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
Answer:
31 ft
Step-by-step explanation:
Let the Woman's Eye level be at Band the top of the statue be at C in the attached diagram.
We want to calculate the height CE of the statue.
CE=CD+DE
First we find CD using trigonometry
Tan 60=CD/15
CD=15 X Tan 60
=25.98 ft
DE=AB= 5ft( Sides of a Rectangle)
Therefore the height of the statue
CE=CD+DE = 25.98+5=30.98 ft
=31ft( to the nearest foot)
199 is the answer because the equation you use is an=a1+d(n-1). Where an (the n is actually supposed to be smaller than the a) is the nth term (a40), a1 (1 smaller than a) is the first term (4), d is the difference (5), and n is the number of the term you're looking for (40)
Answer:
x = 5
Step-by-step explanation:
x² + (2x+2)² = (2x+3)²
x² + 4x² + 8x + 4 = 4x² + 12x + 9
x² - 4x - 5 = 0
(x - 5)(x + 1) = 0
x = -1 This can be discounted as the answer because you cannot have a negative length
answer: x = 5
