Answer:
12m
Step-by-step explanation:
work out the area of the rectangle then times it by 2 because the parallelogram is twice the area of the rectangle. 8 × 4.5m = 36m². 36 ×2 = 72cm². Now you do 72 ÷ 6 = 12 . the answer is 12m.
A cylinder has two bases and a height that (unless oblique) runs right along a side, while a cone has one base and whose height begins at the center of its base and goes straight up to the peak.
Answer:
rectangular container
Step-by-step explanation:
Triangular prism area: A = 1/3 * base area * height
= 1/3 * 12 * 19
= 76 cm²
Rectangular prism: A = base area * height
= 8 * 15
= 120 cm²
The rectangular container has a better value because it has a bigger area and is cheaper.
Hope this helps!
Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)
15 = 5 + 8d - 12
15 = 8d - 7
<u>+7 + 7</u>
22 = 8d
22/8 = d
2.75 = d
Check:
15 = 5 + 4(2(2.75) - 3)
Parentheses first: -3+1 = -2
Multiply: -2*2=-4
Subtract: -4-5=-9
Final Answer: -9
