If a2> 20, then which of the following could be a value of a?

PIT_PIT [208]

Answer:

Step-by-step explanation:

The square root of 20 = 4.47 so a for sure.

But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.

I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.

a for sure.

b and c I think so.

-8 is iffy.

Meiko is hanging a picture collage on her wall. The dimensions of the collage are shown in the diagram. She plans to cover

alexira [117]

Answer: $\frac{A_{collage}}{15.75\ in^2}$

Step-by-step explanation:

Since you did not attach the diagram and I don't know the dimensions of the collage, I will give you a general explanation of the procedure you need to use in order to solve the exercise:

1. You need to use the formula for calculate the area of a rectangle:

$A=lw$

Where "l" is the length and "w" is the width.

2. Using the formula, you must calculate the area of an small picture.

You know that its length is 4.5 inches and its width is 3.5 inches. Therefore, its area is:

$A_{picture}=(4.5\ in)(3.5\ in)\\\\A_{picture}=15.75\ in^2$

3. Calculate the area of the collage using the formula:

$A_{collage}=(l_{collage})(w_{collage})$

4. Finally, divide the area of the collage by the area of an small picture in order to find the number of small pictures that will fit within the collage:

$\frac{A_{collage}}{15.75\ in^2}$
