Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio

Hence The height of tree house is 70.71 feet

Answer:
449 per hour
Step-by-step explanation:
First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.
First:
Know there are 60 minutes in one hour
Second:
Take 7.48 and multiply it by 60
Third:
This should give you---448.8
Which is correct, but we are not done
Fourth:
Round to the nearest whole number
448.8
8 is closer to 10 than it is to 1 so we add 0.2
Which gives us 449
Five:
Just add the "per hour"
Six:
Your answer is---449 per hour---
