Answer:

8

Step-by-step explanation:

10/15=0.66666666666

0.66666666666 times 12 = 8 or the missing length

So the answer is 8 :)

Answer:

He spent 52.5 minutes reading.

Step-by-step explanation:

The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5

Answer:

[tex]Vanillas = \$5.6[/tex]

Step-by-step explanation:

Given

[tex]Cup\ Cakes = 24[/tex]

[tex]Cost = \$0.35[/tex] (each)

[tex]Vanilla = \frac{2}{3}[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

Required

Determine the cost of all vanilla cupcakes

First, we need to determine the number of vanilla cakes.

This is calculated by multiplying the fraction of Vanilla by number of cupcakes

So:

[tex]Vanilla = \frac{2}{3} * 24[/tex]

[tex]Vanilla = \frac{2 * 24}{3}[/tex]

[tex]Vanilla = \frac{48}{3}[/tex]

[tex]Vanilla = 16[/tex]

Since 1 cupcake costs $0.35.

16 would cost 16 * $0.35

So:

Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

Answer:

2/3y + 1 = 1/6y + 8

2/3y - 1/6y = 8 -1

1/2y = 7

y= 7×2/1

y= 14

I attached a diagram that will aid the understanding of the question.

Firstly, I would love to review what a scale factor is before going into the question.

If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.

Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:

1. From P to Q, the scale factor greater than one because Q is bigger than P.

2. From P to R, the scale factor is greater than one for the same reason.

3. From Q to S, the scale factor is less than one because S is smaller than Q.

4. From Q to R, the scale factor is greater than one because R is bigger than Q.

5. From S to P, the scale factor is equal to one because they are equal.

6. From R to P, the scale factor is less than one because p is smaller than R.

7. From P to S, the scale factor is equal to one because they are equal.

Answer:

11.5962

Step-by-step explanation:

2.31 of 5.02

In mathematics, saying "of" is the same as multiplying the two values, hence the problem is;

2.31 * 5.02

= 11.5962

Answer:

$180.48

Step-by-step explanation:

225.60 * .8  = 180.48

Answer:

$45.12

Step-by-step explanation:

100 - 80 = 20

225.60 x .20 = $45.12

Answer:

Tiffany pays a total price of $9.81 for the basket of watermelons

Step-by-step explanation:

Percentages

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

Answer:

9.81 it was confirmed :)

Answer:

27x-24

Step-by-step explanation:

Using distributive property, we can simplify 8(2x-3) to 16x-24. That becomes 16x-24+11x.

Then, we can add 16x and 11x to get 27x.

The answer will be 27x-24.

Answer:

8w+24x-16

Step-by-step explanation:

Answer:

Step-by-step explanation:

what is average speed:

"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."

step one:

given data

Distances   Time

4km             32min

2km              22min

 1km              16min

the total distance covered is

4+2+1= 7km

the total time taken = 32+22+16=70min

the average speed= distance/time

average speed= 7/70= 0.1km per min

Answer: The temperature was 1 8/10º at the end of the day after Mother's Day

Step-by-step explanation:

5 8/10º-14 7/10º=-9 1/10º at the end of Mother’s Day

-9 1/10º+10 9/10º=1 8/10º at the end of the next day after Mother’s Day

Answer:

Step-by-step explanation:

If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.

Slope of a line passing through two points C(4, 5) and D(8, 10),

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{10-5}{8-4}[/tex]

m = [tex]\frac{5}{4}[/tex]

Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]

y - y' = m(x - x')

y - 5 = [tex]\frac{5}{4}(x-4)[/tex]

y = [tex]\frac{5}{4}x-5+5[/tex]

y = [tex]\frac{5}{4}x[/tex]

If point B(4, 0) lies on the line CD,

0 = [tex]\frac{5}{4}(4)[/tex]

0 = 5

Which is not true.

Therefore, point B doesn't lie on line CD.

Answer:

$2368.75

Step-by-step explanation:

Kedar earns a monthly salary of $2200 and a commission of 3.75%

He sold $4500 this month

The first step is to calculate his commission for this month

His commission can be calculated as follows

= 4500 × 3.75/100

= 4500 × 0.0375

= 168.75

Therefore yr amount earned this month can be calculated as follows

= 2200 + 168.75

= $2368.75
