The surface area of the pyramid is multiplied by 100.
======================================================
Explanation:
Consider a square that is 3 by 3. Its area is 3*3 = 9.
Then we'll multiply each dimension by 10 to get a 30 by 30 square. The new larger area is 30*30 = 900. The jump from the old area (9) to the new area (900) is "times 100". We can write 100 as 10^2, where the base of that exponential is the scale factor 10.
This idea can apply to any surface area and not just squares. This is why the surface area of the enlarged pyramid is 100 times that of the original pyramid.
new surface area = 100*(old surface area)
Answer: He would have $1.33 after 3 years glad to help please mark brainliest!
Step-by-step explanation:
using simple interest formula: A = P(1 + r)^t
A= Total amount in 3 years
P=starting total
r=rate of percent as a decimal
t=time in years
A=1(1+0.10)^3
A=1(1+0.10)^3
A=1(1.10)^3
A=1(1.331)
A=1.331
A=1.33
The total area is 78 sq. ft.
Since the medal platform has different measurements, we need to individually compute the area of each polygon.
The top polygon is a square. Its sides measure 3 ft.
A₁ = a²
A₁ = 3 ft²
A₁ = 9 ft²
The middle polygon is a rectangle.
Its total width can be derived by adding the widths given and the width of the square above.
w = 3 ft + 3 ft + 3 ft
w = 9 ft
A₂ = width * height
A₂ = 9 ft * 2 ft
A₂ = 18 ft²
The bottom polygon is also a rectangle.
w = 4 ft + 9 ft + 4 ft
w = 17 ft
A₃ = width * height
A₃ = 17 ft * 3 ft
A₃ = 51 ft²
Total Area = A₁ + A₂ + A₃
T.A. = 9 ft² + 18 ft² + 51 ft²
T.A. = 78 ft²
The answer to your problem is C
Answer:
i think 90 people
Step-by-step explanation:
3,000 - 50 (clean up fee) - 64 (mark and heather) = 2886
32 x 10 = 320 ( cost of ten people )
2886 - (320 x 9) = 6
6 dollars left
