Answer:
320
Step-by-step explanation:
Well, the volume of a pyramid is 1/3 b * h
What is the height of one of these pyramids? Well, they tell you that it's 10. What is the base? It's 6 * 8 = 48
10 * 48 * 1/3 = 160
Now multiply by 2 because there are two pyramids. One on top and one one bottom. 160 * 2 = 320

Circumference = 2 .pi.r
Circumference = 2.pi.8
Circumference =16.pi
Answer:
D) 5,200
Step-by-step explanation:
The formula to find the area of a r rectangle: l x w, where l is the length and w is width.
Area of the backyard: 50 x 80
= 4,000 ft
Area of the house: 40 x 30
= 1,200 ft
Total = 4,000 + 1,200
= 5,200 ft²
Using the law of sins:
B =sin^−1((sin(A)⋅a)/b) = sin^−1((sin(65)⋅110)/155)=40.03 degrees
B= 40.03 degrees (round as needed)
The probability that all three people surveyed is an independent probability and the calculated probability is 0.1225
The probability a surveyed driver is worried = 35%
- Number of people surveyed = 3
Since the probability of being worried is independent ;
- Probability = P(A) × P(B) × P(C)
The probability that all 3 surveyed are worried :
- P(worried) × P(worried) × P(worried)
- (0.35 × 0.35 × 0.35) = 0.1225
Therefore, the probability that all three people surveyed are worried is : 0.1225
