Answer:

I want to show you how to do this as well, the formula you are working with is a^2+b^2=c^2

Step-by-step explanation:

1.) 8^2+b^2=12^2

64+b^2=144

subtract 64 from both sides

b^2=80

take the square root of 80 and you get

b= 8.9

if you need more help on this let me know, I am going to list the other answers now because to do it all and show work on here is a lot of typing, all of which I will do if you do not understand the first example. Also the c value can ONLY BE THE HYPOTENUSE VALUE. The hypotenuse is the longest side of the triangle. For example, 12 would be the C value on number one and in number two it would be 15.

2.) 14.5

3.) 10.3

4.) 18.8

5.) 8

6.) 15

Rectangle M was dilated to form rectangle M’. What ratio is the scale factor?

Gemiola [76]

Solution:

we are given that

Rectangle M was dilated to form rectangle M’.

we have been asked to find

What ratio is the scale factor?

we can find the required ratio by dividing the corresponding sides of the given rectangles as below:

$Ratio=\frac{6}{4}=\frac{2}{4/3}\\ \\\\$

$Ratio=\frac{3}{2}=\frac{6}{4} \\ \\ \ Ratio=\frac{3}{2}=\frac{3}{2}\\$

Hence the required ratio is 3/2.

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?

Lisa [10]

Answer:

At a rate of 5%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question:

Payment plan for $1500 means that $P = 1500$
