B. 42 : 7 = 6 : 2
C. 2 : 3 = 3 : 2
D. 3 : 5 = 12 : 20

Answers

Answer 1

Answer: 15.

2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.

16.
The easiest way to answer this question is by going through each answer one by one:

14:6 = 28:18
28 ÷ 14 = 2
18 ÷ 6 = 3
Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion.

42:7 = 6:2
42 ÷ 7 = 6
7 ÷ 7 = 1
42:7 = 6:1
By dividing both numbers by the same number, we can establish that the answer is wrong.

2:3 = 3:2
This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first.

3:5 = 12:20
12 ÷ 3 = 4
20 ÷ 5 = 4
Since both numbers were multiplied by the same number, this is a true proportion.

The answer is D.

Clare made $160 babysitting last summer. She put the money in a savings account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount by 1.03. How much will she have in 30 years

Answers

Answer:

$388.36

Step-by-step explanation:

let us assume that the amount in her accounts compounds annually

Given data

principal p= $160

interest rate r= 3%= 0.03

time t= 30 years

At the end of 30 years the money she will will have can be expressed as

A= P(1+r)^t

A= 160(1+0.03)^30

A= 160(1.03)^30

A= 160*2.42726

A= $388.36

in 30 years she will have $388.36
