Roger is building a storage shed with wood blocks that are in the shape of cubic prisms. Can he build a shed that is twice as hi
azamat

Complete question is;

Roger is building a storage shed with wood blocks that are in the shape of cubic prisms. Can he build a shed that is twice as high as it is wide?

A. Yes. For every block of width, he could build two blocks high.

B. Yes. He could use half as many blocks for the height as the width.

C. There is no way to determine if he can do this.

D. No, it is not possible to do this

Answer:

A. Yes. For every block of width, he could build two blocks high.

Step-by-step explanation:

We are told that the wood blocks are in the shape of cubic prisms.

Now, cube shapes means that all sides are equal.

Now, if he divides the cube into 2, he can use one have to add to the top to make the height double since the sides are equal.

Thus, the height will now be twice a side of the cubic prism.

Thus, he can build a shed twice as high as its width.

Abner wants to create a shopping budget where he spends less than $80 per month on clothes. He also wants to spend at least thre
strojnjashka [21]

Answer:

D) Abner can spend $60 per month on school clothes and $20 per month on gym clothes and stay within his budget.

Step-by-step explanation:

In the problem it states that Abner will spend 3 times more on (s)school clothes than (g) gym clothes.

So it would appear as s ≥ 3g.

If we plug in $60 as s (school clothes) and $20 as g (gym clothes), the statement is true.

60 ≥ 3(20)

60 ≥ 60. These numbers make the linear system true.

If you have trouble with this, an easy way to find this answer is simply creating the linear system that represents the problem, (he will buy 3 times more school clothes than gym clothes) s ≥  3g and plug in each variable from the answer choices until you find the variables that make the linear system true.
