Answer:
9(5n²+1)
step by step explanations;
5.4/7=27/h
We simplify the equation to the form, which is simple to understand
<span>5.4/7=27/h
We move all terms containing h to the left and all other terms to the right.
<span>-1h=-0.77142857142857
We simplify left and right side of the equation.
<span><span>-1h=-0.77142857142857
</span>We divide both sides of the equation by -01 to get h.
<span>h=0.77142857142857</span></span></span></span>
Answer:
278.63 square inches
Step-by-step explanation:
Gina needs to cut two types of rectangles.
Dimensions of one rectangle is given as,
Width = 12 inches
Length = 
= 
inches
So, the area of this rectangular paper will be
Area = width × length = 
= 171 inches²
Dimensions of the other rectangular paper has been given as
Width = 
= 
inches
Length = 
= 
inches
So, the area of this rectangle will be
Area = width × length = 
= 107.63 inches²
Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.
Answer:
228 in³
Step-by-step explanation:
<u>Volume of a trapezoidal prism</u>
<u>Finding Base Area (on the side here)</u>
- A = 1/2 x (a + b) x h
- A = 1/2 x (12 + 7) x 6
- A = 3 x 19
- A = 57 in²
<u>Volume</u>
- V = A x h
- V = 57 x 4
- V = 228 in³
