Answer:

522

Step-by-step explanation:

We are given that the price of the motorcycle is 3238 and if we borrow it then the payment per month will be 165 for 24 months.

So the total amount that we are going to pay if we borrow the motorcycle will be 165 × 24  = 3960

While the actual price of the bike is 3438.

Difference in the payment and actual price = 3960 - 3438 = 522

Therefore, you can save 522 by paying cash.

Answer:

345 calories.

Step-by-step explanation:

We have been given that there are 230 calories in 4 ounce of a type of ice cream.

First of all let us find calories per ounce ice-cream by dividing 230 by 4.

[tex]\text{Number of calories per ounce ice-cream}=\frac{230}{4}[/tex]

[tex]\text{Number of calories per ounce ice-cream}=57.5[/tex]

Therefore, the ice-cream contains 57.5 calories per ounce of ice-cream.

Let us find amount of calories in 6 ounces of ice-cream by multiplying number of calories per ounce by 6.

[tex]\text{Amount of calories in 6 ounces of ice-cream}=57.5\times 6[/tex]

[tex]\text{Amount of calories in 6 ounces of ice-cream}=345[/tex]

Therefore, there are 345 calories in 6 ounces of ice cream.

17 kids are part of club A and B

Answer: Choice A) 9/45 and 8/40

------------------------

If you divide both top and bottom of 9/45 by the GCF 9, you get 1/5

If you divide top and bottom of 8/40 by the GCF 8, you also get 1/5

So the original fractions must be the same

------------------------

Another way to check is to use a calculator and see that 9/45 = 0.2 and 8/40 = 0.2, so 9/45 = 8/40

Or you can subtract the fractions and you should end up with 0, so, 9/45 - 8/40 = 0

-------------------------

You can also set up a proportion and cross multiply

9/45 = 8/40

9*40 = 45*8

360 = 360

The last equation is true, so the first equation must be true

To find equivalent fractions for 1/12 and 3/8 using the least common denominator, multiply the numerator and denominator of each fraction by the appropriate factor to obtain fractions with a common denominator of 24.

To find an equivalent fraction for 1/12 and 3/8 using the least common denominator, we need to determine the smallest multiple that both denominators (12 and 8) have in common. The least common multiple of 12 and 8 is 24.

To convert 1/12 to a fraction with 24 as the denominator, we need to multiply the numerator and denominator by 2:

1/12 = (1 * 2) / (12 * 2) = 2/24.

To convert 3/8 to a fraction with 24 as the denominator, we need to multiply the numerator and denominator by 3:

3/8 = (3 * 3) / (8 * 3) = 9/24.

Final answer:

The equivalent fractions with the least common denominator of 24 for 1/12 and 3/8 are 2/24 and 9/24, respectively.

Explanation:

To find an equivalent fraction for each fraction with the least common denominator (LCD), you first need to determine the LCD for 1/12 and 3/8. In this case, the LCD for 12 and 8 is 24. Then, you adjust each fraction to have the denominator of 24.

For 1/12: Multiply both the numerator and the denominator by 2 to get 2/24.

For 3/8: Multiply both the numerator and the denominator by 3 to get 9/24.

Therefore, the equivalent fractions with a common denominator of 24 are 2/24 and 9/24.

To understand equivalency in general, when you multiply the numerator and the denominator of a fraction by the same number, you are creating a fraction that represents the same value as the original.

Step-by-step explanation:

__________________________________________

Start at:

____________________

6:00 a.m.

____________________

Add 1  1/4 hours ; which is

1 + (1/4) hours:

Note:  " 1 hr = 60 min." .

_____________________

So:

 (1/4 hr) *  ([tex]\frac{60 min }{ 1 h}[/tex]) ;

                                       =  (1/4) * 60 min;

                                       = (60/4) min.

                                       = 15 min.

______________________

So:  1  1/4 hr =  1 hr. 15 min.;

______________________

So:  Start at:  6:00 a.m .

Add  " 1  1/4 hrs."  ;  i.e. add 1 hr 15 min.

_______________________

6:00 a.m + 1 hr = 7:00 a.m.  ;

 7:00 a.m.  +  15 min. =  7: 15 a.m. ;

_______________________

Now, we are at:

_______________________

7:15 a.m.  ;

Now add:  "1/2 hour" to "7:15 a.m." to this time.

Note:  " 1 hr = 60 min.

So;

"1/2 hr = (1/2) * (60 min) = (60 / 2) min. = 30 min.

________________________

So: we have 7:15 a.m. ;

we add "30 min." to this time.

and we have:  7:45 a.m.

___________________________________________________

The answer is:  " 7:45 a.m. "  .

(a) [tex]\left\{\begin{array}{l}0.8m=2\\p+0.2m=3\end{array}\right.[/tex]

(b) correct choice is 2.5 lb peanuts and 2.5 lb mixture (2.5, 2.5);

Step-by-step explanation:

Let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture.

1. In m pounds of the 80% almond-20% peanut mixture there are 0.8m pounds of almonds and 0.2m pounds of peanuts.

2. When added p pounds of peanuts to m pounds of mixture, you get (p+0.2m) pounds of peanuts and 0.8m pounds of almonds.

3. In 5 pounds of the 40% almond-60% peanut mixture there are [tex]0.6\cdot 5=3[/tex] pounds of peanut and [tex]0.4\cdot 5=2[/tex] pounds of almonds.

(a) Then you get a system of two equations:

[tex]\left\{\begin{array}{l}0.8m=2\\p+0.2m=3\end{array}\right.[/tex]

(b) Solve this system. From the first equation

[tex]m=\dfrac{2}{0.8}=2.5\ pounds,[/tex]

then

[tex]p+0.2\cdot 2.5=3,\\ \\p=3-0.5,\\ \\p=2.5\ pounds.[/tex]

a. The percentage of students who prefer strawberries is 33.33%.

b. The percentage of students who prefer the least favorite fruit is 8.33%.

c. The percentage of students who prefer apples or pears is 45.83%.

A) To find the percentage of students who prefer strawberries:

Add up the total number of students surveyed: 30 (apples) + 15 (oranges) + 40 (strawberries) + 25 (pears) + 10 (peaches) = 120 students.

Determine the number of students who prefer strawberries: 40.

Calculate the percentage: (Number of students who prefer strawberries / Total number of students surveyed) * 100 = (40 / 120) * 100 = 33.33%.

B) To find the percentage of students who prefer the least favorite fruit:

Identify the least favorite fruit, which is peaches with 10 preferences.

Calculate the percentage: (Number of students who prefer peaches / Total number of students surveyed) * 100 = (10 / 120) * 100 = 8.33%.

C) To find the percentage of students who prefer apples or pears:

Add up the number of students who prefer apples and pears: 30 (apples) + 25 (pears) = 55.

Calculate the percentage: (Number of students who prefer apples or pears / Total number of students surveyed) * 100 = (55 / 120) * 100 = 45.83%.

Answer:

0

Step-by-step explanation:

given a + b = 2a ( subtract 2a from both sides )

a - 2a + b = 0

- a + b = 0 ⇒ b - a = 0

Answer:

B

Step-by-step explanation:

distribute parenthesis on both sides of the equation

- 24x - 12 = - 12x - 120 ( add 12x to both sides )

- 12x - 12 = - 120 ( add 12 to both sides )

- 12x = - 108 ( divide both sides by - 12 )

x = 9 → B

Answer:

First man rate is 115

Second man rate is 50

Step-by-step explanation:

Let's assume rate of charge of first men is x

rate of charge of second  men is y

we are given

the sum of the two rates was 165. per hour

so, we get

[tex]x+y=165[/tex]

Two men worked on a car. the first man worked 20 hours and the second man worked 15 hours. Together they charged 3050

so, we get

[tex]20x+15y=3050[/tex]

we can simplify it

[tex]5(4x+3y)=3050[/tex]

[tex](4x+3y)=610[/tex]

so, we got system of equations as

[tex]x+y=165[/tex]

[tex]4x+3y=610[/tex]

We can solve for y from first equation and plug into second equation

[tex]y=165-x[/tex]

[tex]4x+3(165-x)=610[/tex]

[tex]x+495=610[/tex]

[tex]x=115[/tex]

now, we can solve for y

[tex]y=165-115[/tex]

[tex]y=50[/tex]

Answer:

Reflection across y-axis followed by dilation with scale factor 4 and center (0,0).

Step-by-step explanation:

From the given figure it is noticed that the vertices of preimage are E(-2,1), F(-2,0) and G(-3,0). The vertices of image are E'(8,4), F'(8,0) and G'(12,0).

The triangle E'F'G' is enlargement of mirror image of EFG. Therefore reflect the triangle EFG across y-axis. If a point reflects across y-axis, then

[tex](x,y)\rightarrow (-x,y)[/tex]

The new vertices of the triangle are E(2,1), F(2,0) and G(3,0).

Length of FG is 1 unit and length of F'G' is 4 units. The scale factor is

[tex]\frac{F'G'}{FG}=\frac{4}{1}=4[/tex]

Length of OF is 2 unit and length of OF' is 8 units.

[tex]\frac{OF'}{OF}=\frac{8}{2}=4[/tex]

Rule of dilation with scale factor k and origin as center of dilation is defined as

[tex](x,y)\rightarrow (kx,ky)[/tex]

The vertices of image are E'(8,4), F'(8,0) and G'(12,0).

Since the distance ratio of image and preimage from the origin is same as the scale factor, therefore the center of dilation is origin.

Thus, the triangle EFG can form the triangle E’F’G’ using reflection across y-axis followed by dilation with scale factor 4 and center (0,0).

Notes: In this case dilation with scale factor 4 and center (0,0) followed by reflection across y-axis will give the same results.

Answer:

Dilation by a scale factor of 4 followed by reflection about the y-axis

Step-by-step explanation:

given the first 3 terms of the geometric sequence - 4, 20, - 100

with r = [tex]\frac{-100}{20}[/tex] = [tex]\frac{20}{-4}[/tex] = - 5

the n th term formula ( explicit formula ) is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] [tex]r^{n-1}[/tex]

here r = - 5 and [tex]a_{1}[/tex] = - 4, hence

[tex]a_{n}[/tex] = - 4 [tex](-5)^{n-1}[/tex] with n ≥ 1

This question is solved using geometric sequence concepts, and doing this, we get that the correct option is:

[tex]a_n = -4(-5)^{n-1}, n \geq 1[/tex], second option

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is the same, called common ration, and the general equation is given by:

[tex]a_n = a_1q^{n-1}, n \geq 1[/tex]

In which [tex]a_1[/tex] is the first term and q is the common ratio.

-------------------------------------------------------

n an

1 −4

2 20

3 −100

First term is -4, so [tex]a_1 = -4[/tex], then:

[tex]a_n = a_1q^{n-1}, n \geq 1[/tex]

[tex]a_n = -4q^{n-1}, n \geq 1[/tex]

The common ratio is:

[tex]q = \frac{-100}{20} = \frac{20}{-4} = -5[/tex]

Thus:

[tex]a_n = -4(-5)^{n-1}, n \geq 1[/tex] is the sequence.

Answer:

the number is 70

Step-by-step explanation:

let unknown number is 'x'

given that 2x/7=20

multiply by 7 both sides

2x=20*7

divide by 2 on both sides

x=(20*7)/2

x=10*7

x=70

If the quotient of twice a number divided by 7 is 20, then the number is 70.

Let the number be represented as x

Twice the number = 2x

Twice a number divided by 7 = 2x/7

The quotient = 20

To get the value of x:

2x/7   =  20

Cross multiply:

2x  =  7(20)

2x  =  140

x   =  140/2

x  =   70

Therefore, if the quotient of twice a number divided by 7 is 20, then the number is 70.
