Trey will read 18 pages in 45 minutes.
This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18
Answer: approximately 311 feet
I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.
=========================================================
Explanation:
Refer to the diagram below. When using the 47 degree as the reference angle, we know that,
- opposite side = x
- hypotenuse = 325
We can say:
sin(angle) = opposite/hypotenuse
sin(47) = x/425
425*sin(47) = x
x = 425*sin(47)
x = 310.825323188148
x = 311
The kite is approximately 311 feet off the ground.
Answer:
3141.59
Step-by-step explanation:
Formula: V = Pi x Radius(squared) x Height
so
Pi x 10(squared) x 10 = 3141.59
