Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

Answer:
119
Step-by-step explanation:
Find 10% by dividing by 10, then halve it to get 5%. The answers are 14 and 7 accordingly.
Add them together to get 15%, which is now 21.
Take 21 off of 140 to get the answer, which is 119.
ALTERNATIVE METHOD - CALCULATOR
To solve the question using a calculator and with only one equation, multiply the number by 0.85 to find 85% of the number, and there's your answer.
I would think that it would be the first and third
Answer:
No
Step-by-step explanation:
15+ 4 1/2 + 6 3/4 = 26 1/4 in. and that is just 3 3/4 in. less 2 1/2 feet/ 30 in.
<u>Examining the question:</u>
We are given the expression:
We know from Basic trigonometry that:
<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:
Since the denominator of both the values in the denominator is the same:
We know that 
= 
, using the same property:
and we are done!
