{(4, 20), (8, 4), (2, 3), (15, 3), (6, 15), (6, 30), (1, 5), (6, 18), (0, 3)}
a. Write the ordered pair(s) whose first and second coordinate have a greatest common factor of 3So we must find GCF of the ordered pairs
GCF of 4 and 20:
The factors of 4 are: 1, 2, 4
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 4
GCF of 8 and 4:
The factors of 4 are: 1, 2, 4
The factors of 8 are: 1, 2, 4, 8
Then the greatest common factor is 4
GCF of 2 and 3:
The factors of 2 are: 1, 2
The factors of 3 are: 1, 3
Then the greatest common factor is 1
GCF of 15 and 3:
The factors of 3 are: 1, 3
The factors of 15 are: 1, 3, 5, 15
Then the greatest common factor is 3
GCF of 6 and 15:
The factors of 6 are: 1, 2, 3, 6
The factors of 15 are: 1, 3, 5, 15
Then the greatest common factor is 3
GCF of 6 and 30:
The factors of 6 are: 1, 2, 3, 6
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30

Then the greatest common factor is 6
GCF of 0 and 3:
The factors of 0 are: All Whole Numbers
The factors of 3 are: 1, 3
Then the greatest common factor is 3
Summarizing the results:
(15, 3) and (6, 15) and (0, 3) are the ordered pairs whose first and second coordinate have a greatest common factor of 3
b. Write the ordered pair(s) whose first coordinate is a factor of its second coordinate.So let us find the factors of second cordinate and check
For (4, 20) , the factors of 20 are 1, 2, 4, 5, 10, 20
Thus first coordinate 4 is factor of second cordinate
For (8, 4) the factors of 4 are 1, 2, 4
Thus first coordinate is not a factor of second cordinate
For (2, 3), the factors of 3 are 1, 3
Thus first coordinate is not a factor of second cordinate
For (15, 3), the factors of 3 are 1 and 3
Thus first coordinate is not a factor of second cordinate
For (6, 15) , the factors of 15 are 1, 3, 5, 15
Thus first coordinate is not a factor of second cordinate
For (6, 30), the factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30
Thus first coordinate 6 is factor of second cordinate
For (1, 5) , the factors of 5 are 1 and 5
Thus first coordinate 1 is a factor of second cordinate
For (6, 18) , the factors of 18 are 1, 2, 3, 6, 9, 18
Thus first coordinate 6 is factor of second cordinate
For (0, 3) , the factors of 3 are 1 and 3
Thus first coordinate is not a factor of second cordinate
Summarizing the results:
The ordered pair(s) whose first coordinate is a factor of its second coordinate are (4, 20) and (6, 30) and (1, 5) and (6, 18)
c. Write the ordered pair(s) whose second coordinate is a prime number.A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole numbers that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.
Therefore,
(2 , 3) and (15, 3) and (1, 5) and (0, 3) are ordered pair(s) whose second coordinate is a prime numbers
To find the ordered pairs with a GCF of 3, divide the second coordinate by the first to find pairs where the first is a factor of the second, and check the second coordinate for prime numbers.
Explanation:To find the ordered pairs whose first and second coordinates have a greatest common factor of 3, we can go through each pair and check the GCF. The pairs that have a GCF of 3 are (6, 15), (6, 30), and (0, 3).
To find the ordered pairs whose first coordinate is a factor of its second coordinate, we need to divide the second coordinate by the first coordinate and check if the result is a whole number. The pairs that meet this condition are (2, 3), (15, 3), and (0, 3).
To find the ordered pairs whose second coordinate is a prime number, we need to check if the second coordinate is divisible only by 1 and itself. The pair that meets this condition is (2, 3).
Erica says that 1/5 of the national flag of Thailand shown on the right is blue. what’s wrong?
Answer:
The blue portion of the flag is actually 2/6 or 1/3 of the flag
Step-by-step explanation:
If you look at the size of the blue portion of the line it takes up twice the space as the white part. Imagine a small line drawn through the middle of the blue rectangle, now you can see that the flag is split up into 6 parts, rather then 5! Since we now have 2/6 of the flag being taken up by blue, that can be reduced down to 1/3 of the flag covered in blue.

[tex]7 \div 12 = \frac{7}{12} \\ 120 \times \frac{7}{12} = 70[/tex]
Answer:
B
Step-by-step explanation:
Given that for every 12 seeds, 7 grew into plants
Then for 120 seeds, that is 120 ÷ 12 = 10 times as many seeds, thus
number growing into plants = 10 × 7 = 70 → B
This table gives a few (z,y) pairs of a line in the coordinate plane.
-56 66
-42 58
-28 50
What is the y-intercept of the line?
Answer:
The y-intercept of the line is 34.
Step-by-step explanation:
There are few points on the z-y plane through which a straight line passes.
The points are (-56,66), (-42,58) and (-28,50).
Now, take the first two points to get the equation of the straight line.
The equation is [tex]\frac{y - 58}{58 - 66} = \frac{z - (-42)}{-42 - (- 56)}[/tex]
⇒ [tex]\frac{y - 58}{- 8} = \frac{z + 42}{14}[/tex]
⇒ 14(y - 58) = - 8(z + 42)
⇒ [tex]y - 58 = - \frac{8}{14}z - 24[/tex]
⇒ [tex]y = - \frac{8}{14}z + 34[/tex]
This equation is in slope-intercept form.
Hence, the y-intercept of the line is 34. (Answer)
Si n es un número impar,¿ cual de las siguientes opciones representa un numero par? a) 2n +1 b) n(n+2) c) n+(n-1) e) 2(n+1)
Answer: e) 2(n+1)
Step-by-step explanation:
De las opcionas dadas, e) 2(n+1) es la correcta.
Empecemos por explicar la siguiente regla:
(número par)(número par)=número par
(número par)(número impar)=número par
(número impar)(número impar)=número impar
Ahora bien, en la expresión 2(n+1) el resultado de lo que se encuentra dentro del paréntesis va a ser multiplicado por 2, el cual es un número par, por lo tanto el resultado final va a ser un número par independientemente de si lo que está en el paréntesis es par o impar.
Por ejemplo, si elegimos 1 que es impar:
2(1+1)=2(2)=4
El resultado es par.
Si probamos con las otras opciones, los resultados serán impares:
a) 2n +1
2(1)+1=2+1=3 impar
b) n(n+2)
1(1+2)=1(3)=3 impar
c) n+(n-1)
1+(1-1)=1+0=1 impar
Ava and Addison are saving for a new cell phone. Ava is starting at 100$ and adding 5$ each week.Addison is starting with 200$ and is adding 4$ each week. Write and solve a problem that can be used to find out after how many weeks Ava and Addison will have the same amount of money saved?
Answer:
The numbers of weeks for which both Ava and Addison have same amount of money saved is 100 weeks .
Step-by-step explanation:
Given as :
The amount of money having with Ava at starting = $100
The money that Ava is saving each week = $5
The amount of money having with Addison at starting = $200
The money that Addison is saving each week = $4
Now, Let The numbers of weeks for which both Ava and Addison have same amount of money saved = n weeks
Now, According to question
The amount of money having with Ava at starting + (The money that Ava is saving each week × numbers of weeks) = The amount of money having with Addison at starting + (The money that Addison is saving each week × numbers of weeks)
Or, $100 + $5 × n = $200 + $4 × n
Or, $5 × n - $4 × n = $200 - $100
Or, n = 100
So, The numbers of weeks for which both Ava and Addison have same amount of money saved = n = 100 weeks
Hence,The numbers of weeks for which both Ava and Addison have same amount of money saved is 100 weeks . Answer

Solve the following system of equations graphically: y=3x+4 and y=-2x-5
Answer:
(x, y) = (-1.8, -1.4)
Step-by-step explanation:
Modern graphing calculators make it trivially simple to solve many problems by graphing. It has become my favorite method.
The graph shows the solution to be (x, y) = (-1.8, -1.4).
___
If you're graphing by hand, it is usually convenient to start with the y-intercepts, then draw the lines with the required slopes. These equations are written in slope-intercept form, making that approach relatively simple.
The first equation has a y-intercept of (0, 4) and a slope of 3. So, another point on the graph will be left 1 and down 3 (as opposed to right 1 and up 3). That point is (-1, 1).
The second equation has a y-intercept of (0, -5) and a slope of -2. So, another point on the graph of that will be left 1 and up 2, to (-1, -3)

In a shop, apples cost 27p each and oranges cost 36p each.
Muhammed bought some apples and oranges in the shop. He paid £1.53.
Work out how many apples and how many oranges Muhammed bought.
HELP!
Answer:
The number of apple bought is 3
The number of orange bought is 2
Step-by-step explanation:
Given as :
The price of each apple = 27 p = 27 × 0.01 pound = 0.27 pound
The price of each orange = 36 p = 36 × 0.01 pound = 0.36 pound
The Total money paid for the fruits = 1.53 pounds
Let The Total number of apple bought = a
And The Total number of orange bought = o
Now, According to question
Total money paid for the fruits = Total number of apple bought × price of each apple + Total number of orange bought × price of each orange
Or, 0.27 a + 0.36 o = 1.53 ......A
Here The Total quantity of fruits bought is not given, so apply hit and trial method to calculate total number of each fruit
Let The a = 1 and o = 1
So, 0.27 × 1 + 0.36 × 1 = 1.53
∴ 0.63 ≠ 1.53
Again
Put a = 2 , o = 2
So, 0.27 × 2 + 0.36 × 2 = 1.53
∴ 1.26 ≠ 1.53
Again
Put a = 3 , o = 3
So, 0.27 × 3 + 0.36 × 3 = 1.53
∴ 1.89 ≠ 1.53
Now, Let a = 3 , o = 2
So, 0.27 × 3 + 0.36 × 2 = 1.53
∴ 1.53 = 1.53
so, from hit and trial method , we get the number of apple = a = 3
And he number of orange = o = 2
Hence, The number of apple bought is 3
And The number of orange bought is 2 . Answer

Suppose a snow cone has a paper cone that is 8 centimeters deep and has a diameter of 5 centimeters. The flavored ice comes in a spherical scoop with a diameter of 5 centimeters and rests on top of the cone. If all the ice melts into the cone, will the cone overflow? Explain.
Answer:
D
Step-by-step explanation:
We require to calculate the volume (V) of the cone and sphere.
The volume of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V = [tex]\frac{1}{3}[/tex]π × 2.5² × 8 ≈ 52.36 cm³
The volume of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V= [tex]\frac{4}{3}[/tex]π × 2.5³ ≈ 65.45 cm³
Since volume of the sphere is greater than the volume of the cone
Thus when the ice cream melts it will overflow → D
7. Nick’s youth group has 20 regular students that attend weekly get togethers. They saved up enough money for each person to go swimming 10 times each with the daily pay plan. After they saved that amount, they found out they can use the early pay plan and save money. They plan to donate their savings to the church since it’s in need of a new sound system. How much money will they be able to donate with the savings from all 20 youth? (Please show all your work for full credit)
WILL GIVE BRILIEST
Answer:
If each youth saves $10 daily, their weekly savings would be $1400. So they donated $1400 to the church.
Step-by-step explanation:
Let the daily pay plan for each youth be $y
Daily pay plan for 20 youth = $20y
Weekly pay plan = 7×20y = $140y
Assuming each youth saves $10 daily
Daily savings for 20 youth = 20×$10= $200
Weekly savings for 20 youth = 7×$200= $1400
If they used the early pay plan ($140y) to go swimming, they saved $1400 which they donated to the church.
Answer:
$375 saved or roughly 33%.
Step-by-step explanation:
With daily plan;
(15)4.00 = 60.00
(25)60.00 = $1,500.00
If the youth group saved up enough for each of them to swim 15 times and 25 students are attending, they originally had $1,500.00 saved for the trip.
With early pay;
(25)45.00 = $1,125.00
1,500.00 - 1,125.00 = $375 saved or roughly 33%.
Hope this helps! And please, do not copy-paste this answer. Write it in your own words, thanks <33
Zolt Inc. (zolt) stock is selling for $8.22 per share with an EPS of .45 cents per share. What is Zolt's PE ratio? (Round to nearest tenth.)
rev: 09_19_2013_QC_35406
18.3
19.5
8.3
20.0
None of these
Answer:
18.3 ( when EPS is 45 cents), otherwise there is none of these
Step-by-step explanation:
PE = Current Price / EPS
current Price = $ 8.22 = 822 cents
EPS = .45 cents (?) ... is it 45 cents ?
if it is 45 cents : PE = 822 / 45 = 18.26 ≈ 18.3
The required PE ratio of the Zolt's is given as 18.3. Option A is correct.
Given that,
Zolt Inc. (zolt) stock is selling for $8.22 per share with an EPS of .45 cents per share.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
PE = Current Price: EPS
PE = Current Price / EPS
Current Price = $ 8.22 = 822 cents
EPS = 0.45 cents = 45 cents
it is 45 cents per PE
So Ratio = 822 / 45 = 18.3
Thus, the required PE ratio of the Zolt's is given as 18.3. Option A is correct.

Solve 4^(x+2) = 12 for x using the change of base formula log base b of y equals log y over log b.
Answer:
[tex]x \approx -0.208[/tex]
Step-by-step explanation:
By applying logarithms to each side of the equation and some algebraic handling:
[tex]x+2 = \log_{4} 12[/tex]
[tex]x + 2 = \frac{\log_{10} 12}{\log_{10} 4}[/tex]
[tex]x = \frac{\log_{10}12}{\log_{10}4} - 2[/tex]
[tex]x \approx -0.208[/tex]
Final answer:
To solve the equation
[tex]4^{x+2} = 12[/tex]for x, you can use the change of base formula log base b of y equals log y over log b. By following the steps, you should find the solution to be x ≈ -0.086.
Explanation:
To solve the equation
[tex]4^{x+2} = 12[/tex]for x, we can use the change of base formula log base b of y equals log y over log b. Let's solve it step by step:
Take the logarithm of both sides of the equation using any base (let's use base 10 for this example): [tex]log (4^{x+2})[/tex] = log 12Apply the power rule of logarithms: (x+2) * log 4 = log 12Divide both sides by log 4: x+2 = log 12 / log 4Subtract 2 from both sides to isolate x: x = log 12 / log 4 - 2Use a calculator to evaluate the right side of the equation: x ≈ -0.086Therefore, the solution to the equation
[tex]4^{x+2} = 12[/tex]is approximately x = -0.086.

(SAT Prep) In the given figure, find x for which a ∥ b?
A. 50° B. 65° C. 75° D. 95°
Please explain your answer, and thanks in advance :)
Answer:
x= 65 degrees
Step-by-step explanation:
If the triangles vertices are marked CDE (d as the right angle and c as the leftmost vertex) then:
Alternate interior angles
⇒m∠ACE=85 degrees
m∠ACD=25 and m∠ACD+m∠DCE=m∠ACE=85 degrees
⇒ 25 + m∠DCE= 85 ⇒ m∠DCE=60 degrees
Since the sum of the angles in a triangle is 180 degrees
⇒ 60 + 90 + m∠DEC = 180 ⇒ m∠DEC= 30 degrees
Finally, since ∠BEC is supplementary to the given 85 degree angle
⇒ 30 + 85 + x = 180 ⇒ x=65
Answer:
[tex]\huge\boxed{x = 65 \ \text{degrees}}[/tex]
Step-by-step explanation:
We can use angle relationships to find the measure of [tex]x[/tex] here.
Let's assume that the triangle has the points ABC, where m∠a is the leftmost angle, m∠b is the right angle, and m∠c is the rightmost angle (I've labeled it in the attached picture).
We have to realize here that a and b are parallel lines. This means that the angles on one side will be equivalent to the other as long as the triangle in the center is symmetrical along both.
It's not. However, we can make it symmetrical by realizing that the 85° angle is the exact same as Line A AC. These are alternate interior angles, meaning their angle measurements will be the same. So Line A A C is also 85°.
Line A A C covers the area even in the triangle. Since we know the total measure and the measure outside the triangle, we can find the measure of m∠a.
[tex]25 + a = 85\\\\a = 85-25\\\\a = 60[/tex]
Now we know that m∠a is 60°. We also know that m∠b is a 90° angle. All triangle angles add up to 180°. Since we know two out of the three, let's find the measure of m∠c by adding up what we know and subtracting from 180.
[tex]60+90+c=180\\\\150+c=180\\\\c=180-150\\\\c=30[/tex]
Now that we know m∠c, we can note that the 85° angle, m∠a, and x are supplementary. This means their angle lengths add up to 180°. Since we know two out of the three, we can do a process similar to finding the missing triangle angle.
[tex]85+30+x=180\\\\115+x=180\\\\x=180-115\\\\x = 65[/tex]
Therefore, x is 65°.

Answer:
∠A ≈ 19.47°
Step-by-step explanation:
As you know , the angle that tangent makes with the radius at the point of tangency is 90°.
∴∠OKA = 90°
As AO = 15 and OK = 5 ,
[tex]sin(A) = \frac{OK}{AO}[/tex]
[tex]sin(A) = \frac{5}{15} [/tex]
[tex]sin(A) = \frac{1}{3} [/tex]
∠A = [tex]sin^{-1} (\frac{1}{3} )[/tex]
∠A ≈ 19.47°
Answer:
[tex]\mathbf{m\angle A = sin^{-1}(\frac{1}{3}) \approx 19.47^{\circ}}[/tex]
Step-by-step explanation:
This question involves some basic knowledge of trigonometric function. The following formula only works for right angled triangles.
[tex]\mathbf{sin(x) = \frac{perpendicular}{hypotenuse}}[/tex]
In ΔAKO,
m∠AKO = 90°
Therefore ΔAKO is a right angled triangle. If we take ∠A into consideration then base will be AK, perpendicular will be OK and hypotenuse will be AO.
AO = 15
OK = 5
[tex]\therefore \mathrm{sin(\angle A) = \frac{OK}{AO} = \frac{5}{15} = \frac{1}{3}}[/tex]
[tex]\mathrm{sin(\angle A)=\frac{1}{3}}[/tex]
[tex]\mathrm{\angle A=sin^{-1}(\frac{1}{3})}[/tex]
To calculate [tex]\mathrm{sin^{-1}(\frac{1}{3})}[/tex] use scientific calculator
value of [tex]\mathrm{sin^{-1}(\frac{1}{3})}[/tex] is approximately equal to 19.47°
Therefore [tex]\mathbf{m\angle A \approx 19.47}[/tex]
(NOTE : When a line passing through center of a circle, is drawn to a tangent at the point of tangency then the angle made between then is 90°
Therefore m∠AKO = 90°)
line m passes through the points -2,7 and 4,-5 as shown below.
Answer:

If w=45,what is the value of 2(w-7)
Answer:
76
Step-by-step explanation:
if w=45, you'd get 2(45-7) by replacing the variable (w) with its value (45)
so first you'd distribute 2 to the 45 and the 7
now it'd be:
90-14=76
so the answer would be 76! :)
Answer:
The answer is 76
Step-by-step explanation:
First you swap in the number like so: 2(45-7)
Then you figure out what's is the parentheses first going with PEMDAS like so : 2(38)
Finally you multiply the number getting your final answer which is :76
