Use rounding to estimate the product 12*9. Then, use compensation to find the actual answer. If Alison was rounding to find how

much 12 books that were $9 apiece cost, would she get a good estimate? Explain.

I would do 12 x 10 = 120
to compensate do 120 - 12 =108 same as 12*9 = 108

The estimate is decent, because we are only $12.00 from the real answer.

What is the multiplicative inverse of the sum of 1/3 + 1/5 ? Express in simplest form

Dima020 [189]

$\frac{8}{15}$

My Work/Reasoning:
First we find the sum of 1/3 and 1/5. $\frac{1}{3} + \frac{1}{5} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15}$
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal. $\frac{8}{15}$ turns into $\frac{15}{8}$
Finally, we simplify. $\frac{15}{8}=1 \frac{7}{8}$

nydimaria [60]

Answer:

A. 112 m^2

Step-by-step explanation:

If the scale factor is 4, the area of the larger figure is 4^2 times that of the smaller one.

... (7 m^2)·4^2 = 112 m^2

_____

The scale factor for area is the square of the scale factor for linear dimensions. When we talk about a scale factor without qualification, we mean the scale factor for linear dimensions.
