Answer:
Step-by-step explanation:
V=lwh=4*5*10=200 cubic inch or in^3
6-2.8=3.2
6+3.2=9.2
the answer is 9.2
This can be represented by the inequality 8

12
As Dina wants at least 8, and no more than 12, that means 8, 9, 10,11, and 12, are applicable
The equation that can be used to solve for SC is 10/18 = SC/24
<h3>What are similar triangles?</h3>
They are triangles having similar sides and angles.
From the diagram shown, we can use the similarity theorem of triangles to get the measure of SC
From the figure we are given the information:
- CR= 10,
- CB = 18, and;
- AC = 24
According to the similarity theorem'
CR/CB = SC/AC
10/18 = SC/24
Hence the equation that can be used to solve for SC is 10/18 = SC/24
