A book sold 31,100 copies in its first month of release. Suppose this represents 7.8% of the number of copies sold to date. How

zvonat [6]

For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.

Answer:

$2,239.66

Step-by-step explanation:

To find the amount of reimbursement, convert miles to km by multiplying 1564 by 1.609 since 1 mile = 1.609 km.

He drive 1564(1.609)=2,516.476 km.

Multiply this distance by $0.89 per km.

2516.476(0.89)=$2,239.66

John is buying new shoes. He finds the shoes he wants on sale for 30%, and the original price is $88. How much will he pay for t

Brilliant_brown [7]

Answer:

61.6 dollars

Step-by-step explanation:

So, lets go over what we know:

The shows orginally cost 88 dollars.

They are 30% less than that.

This basically means that the shoes will cost 70 percent of their orginal price.

We can basically find the new cost by multiplying the 88 dollars by the 70 percent.

Or, multiplying 88 by 0.7, which is the decimal form of 70%.

88*0.7=61.6

How did I get this?

Multiply 80 by 0.7:

7*8=56

We have 0.7 so it = 5.6

However, it's tens place is 80, not 8, so it will be = 56

It is the same thing in the ones place, however it is 8 not 80, so it will be 0.7*8

= 5.6

56+5.6=61.6

So 61.6 is our answer.

Hope this helps!

What is the ratio of the perimeter of ΔHKO to the perimeter of ΔFGO

Lera25 [3.4K]

Answer:

Part 1) The ratio of the perimeter of ΔHKO to the perimeter of ΔFGO is $\frac{1}{2}$

Part 2) The ratio of the area of ΔKHO to the area of ΔGFO is $\frac{1}{4}$

Step-by-step explanation:

Part 1)

we know that

If two figures are similar , then the ratio of its perimeters is equal to the scale factor

In this problem

Triangles HKO and FGO are similar by AAA Theorem

Find the scale factor

The scale factor is equal to the ratio of its corresponding sides

$\frac{4}{8}=\frac{7}{14}=\frac{1}{2}$

Part 2) Find the ratio of the area of ΔKHO to the area of ΔGFO

Area of ΔKHO

$A=4*7/2=14\ units^{2}$

Area of ΔGFO

$A=8*14/2=56\ units^{2}$

The ratio of its areas is equal to

$\frac{14}{56}=\frac{1}{4}$

Alternative Method

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem we have that

The scale factor is $\frac{1}{2}$

squared the scale factor

$(\frac{1}{2})^{2}=\frac{1}{4}$ ----> is correct
