Answer:
Reflect about the y axis
Step-by-step explanation:
please mark brainliest :)
Step One
Find the area of the base
A = s * s
s = 755.5 feet
Area = 755.5^2
Area = 570780.25 square feet.
Step two
Multiply the volume by 3
V = 1/3 B * h
3*V = B * h
V = 85600000
85600000 * 3 = B * h
256800000 = B * h
Step Three
Divide by B
B = 570780.25
256800000 = 570780.25 * h
256800000 / 570780.25 = h
449.91 feet = h
Answer:
12
Step-by-step explanation:
By ythagoras Theorem,
x^2 + 9^2 = 15^2
x^2 + 81 = 225
x^2 = 225 - 81
x^2 = 144
x = √144
x = 12
√52-√13+√117
sqrt (4*13) - sqrt (13) + sqrt (13*9)
sqrt(4)sqrt(13) -sqrt(13)+sqrt(13)sqrt(9)
2sqrt(13) -sqrt(13)+3sqt(13)
sqrt(13)[2-1+3]
4sqrt(13)
Choice A
Solution:
<u>Step-1: Find the missing side length using Pythagoras theorem:</u>
- 115² = 69² + x²
- => 13225 = 4761 + x²
- => 13225 - 4761 = x²
- => 8464 = x²
- => x = √8464 = 92
<u>Step-2: Find the area of the rectangle:</u>
- Area of rectangle = LB
- => 69 x (92 + 100)
- => 69 x 192
- => 13248 units²
