Answer:

base = 3.1 cm

Step-by-step explanation:

b= base

perimeter= p

From the statement we know that p=15.7 cm

moreover:

a=c=6.3 cm

So we have:

15.7=2*a +b

15.7 = 2*6.3 +b

15.7-12.6 = b

b= 3.1 cm = base

Lin has a drawing with an area of 20 in squared. If she increases all sides by a scale factor of 4, what will the new area be?
diamong [38]

The new area will be 320 in²

<em><u>Explanation</u></em>

Lin has a drawing with an area of 20 in² and she increases all sides by a scale factor of 4.

<u>The general rule</u> we need to use here.......

"<em>If the lengths of the sides in a shape are all increased by a scale  factor of  k, then the area will be increased by a scale factor of  k^2"</em>

Here the sides are increased by a scale factor of 4. So, the area will be increased by a scale factor of  (4)^2 =16

Thus, the new area will be:  (20*16)in^2 = 320in^2

A 14-ounce box of cereal sells for $2.10. What is the unit rate?
Ahat [919]

Answer:

The unit rate is equal to 0.15\frac{\$}{ounce}

Step-by-step explanation:

we know that

The unit rate is the ratio of two measurements in which the second term is equal to one

In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal

so

\frac{2.10}{14}\frac{\$}{ounces} =0.15\frac{\$}{ounce}

therefore

The unit rate is equal to 0.15\frac{\$}{ounce}
