Answer:
The surface area of the green prism is 6.25 times greater than the surface area of the blue prism.
Step-by-step explanation:
The surface area of both prisms consists of six rectangles: top, base, front, back, left side and right side. In terms of surface area, top=base, front=back and left side=right side, so the total surface area for each prism is:
2(base area)+2(back area)+2(side area)
=2((base area)+(back area)+(side area))
Area of blue prism = 2((base area)+(back area)+(side area))
=2((4*2)+(4*10)+(2*10))
=2(8+40+20)
=2(68)
=136 cm²
Area of green prism = 2((base area)+(back area)+(side area))
=2((10*5)+(25*10)+(25*5))
=2(50+250+125)
=2(425)
=850 cm²
850cm² is 6.25 times greater than 136cm² <em>(850/136=6.25)</em>, so therefore, the surface area of the green prism is 6.25 times greater than the surface area of the blue prism.
To find the lateral surface area, use the following formula
la = π × r × s
Given:
π = 3.14
r = 7 ft
s = 13 ft
Solution
Input the numbers to the formula
la = π × r × s
la = 3.14 × 7 × 13
la = 285.74
The lateral surface area of the cone is 285.74 square feet
Store pays ($3)
Store sells it for ($5.70)
The percent is always (100%) when there selling it.
markup= $3 ÷ $5.70 · 100% = 1.9
Answer:
She could have just done 42-23 = x and solved the equation in one step because if 23 and x add up to 42, then subtracting one from 42 will result in the other. This means both equations are equivalent, but 42-23 is faster and simpler.
