but to do this you must first change the decimal to a fraction. Personally i use a decimal calculator.
then you go to where the 3 is on the Y axes. since its positive 3 it would be 3 up instead of down.
then you count over how ever many the X is. this is 1/2 so you go over 1 time then up 2 times.
Personally I like the triangle method where u plot the +3 then draw on the line 1 over then 3 up
if u need to find out what the plot line u can keep doing that all the way up and just reverse it when u go down.

√63 = √9√7= 3 √7
Now replace the above value with the given expression
2*2√5 - 3√7 -2√5+4*3√7
= 4√5 - 3√7-2√5+12√7
= 4√5 -2√5 - 3√7 +12√7
Simplifying the like terms, we get
= 2√5 + 9√7
Thank you.
The expression 2 sqrt(20) - 3 sqrt(7) - 2 sqrt(5) + 4 sqrt(63) simplifies to 2 sqrt(5) + 9 sqrt(7) after breaking down and combining like radicals.
We start by simplifying each radical. Notice that sqrt(20) can be written as sqrt(4*5), which simplifies to 2sqrt(5). Similarly, sqrt(63) can be written as sqrt(9*7), which simplifies to 3sqrt(7). Therefore, our expression becomes:
2(2sqrt(5)) - 3sqrt(7) - 2sqrt(5) + 4(3sqrt(7)) = 4sqrt(5) - 2sqrt(5) - 3sqrt(7) + 12sqrt(7) = 2sqrt(5) + 9sqrt(7). This gives us the simplified form of the original expression.

the measure of the vertex angle of an isosceles triangle is 48°. what is the measure of each base angle?
Answer:
66°
Step-by-step explanation:
the base angles of an isosceles triangle are equal
the sum of the 3 angles in a triangle = 180°
subtract the vertex angle from 180 and divide the result by 2
base angles = 180° - 48° = 132°
base angle = [tex]\frac{132}{2}[/tex] = 66°

Final answer:
The Giants scored 17 points in the last game.
Explanation:
To find the number of points the Giants scored, we need to set up an equation using the given information. Let's represent the number of points scored by the Giants as 'G'.
According to the problem, the Cowboys scored 10 less than three times the number of points the Giants scored, which can be written as: 3G - 10 = 41. To solve this equation, we can add 10 to both sides: 3G = 51.
Finally, divide both sides by 3 to find the value of G: G = 17.

Answer:
Step-by-step explanation:
If the lines are parallel, then angles 1, 7, 3, and 5 are congruent because they are vertical/corresponding angles.
Therefore, they are all 113 degrees. For the rest of them, you just subtract from 180 to get 67. Therefore,
2 = 67 degrees
3 = 113 degrees
4 = 67 degrees
5 = 113 degrees
6 = 67 degrees
7 = 113 degrees
8 = 67 degrees

What is the selling cost of a jacket that the store buys for $60 if the markup is 12%?
Answer:
$67.20
Step-by-step explanation:
We need to find out how much 1% costs so we can multiply that cost by 12 because it goes up 12%.
60/100=0.6
0.6*12=7.2
Now that we have the markup amount we add it to the actual price of $60 so
60+7.2=$60.20
Find x, using SOHCAHTOA?
Answer:
x = 57.22754579
Step-by-step explanation:
We know cos 63 = adjacent/ hypotenuse
cos 63 = 15 sqrt(3)/x
Multiply each side by x
x cos 63 =15 sqrt( 3 )
Divide each side by cos 63
x cos (63)/ cos (63) = 15 sqrt(3)/cos (63)
x = 15 sqrt(3)/ cos 63
x = 57.22754579

After an outbreak of a mysterious disease the average wait time at a hospital increased by 70%. Before the outbreak, the average wait time at the hospital with M minutes. Which of the following expressions could represent the average time at the hospital after the outbreak? Choose two answers:
Answer:
[tex]\frac{170}{100}m[/tex]
[tex]1.7m[/tex]
Step-by-step explanation:
Here,
Before the outbreak, the average wait time at the hospital was m minutes,
Also, after outbreak it is increased by 70 %,
So, the average wait time at the hospital after the outbreak = The average wait time before outbreak + 70 % of the average wait time before outbreak
= m + 70 % of m
[tex]=m+\frac{70m}{100}[/tex]
[tex]=\frac{100m+70m}{100}[/tex]
[tex]=\frac{170m}{100}[/tex]

The prices per pound of different types of nuts are shown. write an expression that can be used to find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds, all for 20 % off.
Peanuts = $3.95 per pound
Cashews = $4.25 per pound
Almonds = $5.99 per pound
Please help! Thank you
Answer:
expression for total cost is given by
[tex]0.80(3.95x+4.25y+5.99z)[/tex]
Step-by-step explanation:
Here we need to find the expression for the total cost
Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds
cost of 1 pound of peanut = $3.95
cost of x pounds of peanut = $3.95x
cost of 1 pound of cashews = $4.25
cost of y pounds of cashews = $4.25y
cost of 1 pounds of almonds = $5.99
cost of z pounds of almonds = $5.99z
total cost = [tex]3.95x+4.25y+5.99z[/tex]
cost after 20% off = total cost - 20% of total cost
= 80% of total cost
cost after 20% off =80%[tex](3.95x+4.25y+5.99z)[/tex]
cost after 20% off =[tex]0.80(3.95x+4.25y+5.99z)[/tex]
now we can plug x= 2 , y= 3 and z=1
so we have
cost after 20% off =[tex]0.80(3.95(2)+4.25(3)+5.99(1))[/tex] =$ 21.31
The expression is ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20) which equals to $21.31.
To find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds with a 20% discount, we need to first calculate the original total cost of the nuts without the discount.
We do this by multiplying each type of nut's price per pound by the number of pounds purchased and summing these amounts up.
The cost for the peanuts is 2 pounds x $3.95 per pound = $7.90.
For the cashews, it is 3 pounds x $4.25 per pound = $12.75.
For the almonds, it is 1 pound x $5.99 per pound = $5.99.
The sum of these costs will give us the total original cost.
The total original cost is therefore $7.90 (peanuts) + $12.75 (cashews) + $5.99 (almonds) = $26.64.
Next, we apply the 20% discount by multiplying the total original cost by 20% (or 0.20) to find the discount amount, and then subtract this discount amount from the total original cost to find the discounted total cost:
Discount amount = $26.64 imes 0.20 = $5.33. Discounted total cost = $26.64 - $5.33 = $21.31.
Therefore, the expression that can be used to find the total cost is: ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20)

in a certain city , the hourly wage of workers on temporary employment crontracts is normally distributed. The mean is $15 and the standar deviation is $3. What percentage of temporary workers earn less than $12 per hour?
A) 6%
B) 16%
C) 26%
D) 36%
Answer:
16%
Step-by-step explanation:
The mean is $15 and the standar deviation is $3.
mean = 15 and SD = 3
We need to find percentage less than 12 per hour
P(x<12)= P(x=12)
to find P(x=12) we find z-score
[tex]z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1[/tex]
Now use z-score table . z-score = 0.1587
P(x=12)=0.1587
To get percentage we multiply by 100
0.1587 * 100 = 15.87 = 16%

Ginger's cat gave birth to a kitten that weighed ounces when it was born. On the day Ginger sold the kitten to its new owner, it weighed ounces. How many ounces did the kitten gain before it went home with its new owner?
Answer:
C. 2 1/8 ounces
Step-by-step explanation:
The kitten gained 2 1/8 ounces, and you can prove it through the following reasoning.
Kitten at birth was 3 3/8 ounces
Gained Weight (WG) was (unknown)
The kitten was 5 1/2 after being sold.
5 1/2 - 3 3/8 = GW (please note that 1/2 is also 4/8, therefore the equation can be represented by 5 4/8 - 3 3/8 = GW
2 1/8 = GW
Answer: The kitten gained 2 1/8 ounces
Step-by-step explanation:
We have to find the difference between the weights of kitten.
5 1/2 - 3 3/8 = weight gained
We solve the compound fraction like this.
5 1/2
2*5+1 = 11
This goes to 11/2
While
3 3/8
8*3+3 = 27
This goes to 27/8
So we subtract 11/2 - 27/8
44 - 27/8
17 / 8
This comes to 2 1/8 ounces.

To solve the system of linear equations 3x-2y=4 and 9x-6y=12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3x-2y=4 and 9x-6y=12 with his graphing calculator, but he could only see one line. Why is this?
A.because the system of equations actually has only one solution
B.because the system of equations actually has no solution
C.because the graphs of the two equations overlap each other
D.because the graph of one of the equations does not exist
The coefficients and constants of the equations are proportional to each other because the graphs of the two equations overlap each other.
The correct option is C.
When Henry multiplied the first equation by -3 and added the two equations together, resulting in the equation 0 = 0, it indicated that the two original equations were dependent and represented the same line. This means that the system of equations has infinitely many solutions. Each point on the line represented by the equations satisfies both equations simultaneously.
When Henry graphed the equations on his graphing calculator and saw only one line, it further confirmed that the two equations are identical or overlapping. The lack of a visible second line indicates that the graphs coincide with each other, overlapping perfectly. This occurs because the coefficients and constants of the equations are proportional to each other, resulting in the same line when graphed.
Hence, option C is the correct choice, as the overlapping of the graphs confirms that the system of equations has infinitely many solutions.

m=d1440
m = 1440d
Answer:
Last choice
Step-by-step explanation:
Let's assume m is the "y" (dependent variable) and d is the "x" (independent variable) because the number of minutes is larger, and that would make more sense.

Find the length of x.
Answer:
x=7
Step-by-step explanation:
The two triangles are similar .
We can use the ratio's of the side to figure out x
2 3.5
-------- = --------------
4 x
Using cross products
2x = 4*3.5
2x=14
Divide each side by 2.
2x/2 = 14/2
x=7
the length of x = 7.
To solve for x using the given ratios of the sides of the two similar triangles, we can follow these steps:
Set up the proportion using the given ratios:
[tex]\[ \frac{2}{4} = \frac{3.5}{x} \][/tex]
Cross multiply:
[tex]\[ 2x = 4 \times 3.5 \][/tex]
Perform the multiplication on the right side:
2x = 14
To solve for x, divide both sides of the equation by 2:
[tex]\[ \frac{2x}{2} = \frac{14}{2} \][/tex]
Simplify both sides:
[tex]\[ x = \frac{14}{2} \][/tex]
Calculate the value:
x = 7
So, x = 7.
Find the length of x.
