Answer:
10) It increased by appoxamately 17%.
11) 255 decreased by 20%
12) 15 increased by 
%
13) $9,450
14) $149.8
15) $238.5
Step-by-step explanation:
10) 170 is greater than 150 by 25. 25 is 
% of 150, so it increased by appoxamately 17%.
11) 225 is decreased by 45. 45 is 20% of 100, so 255 decreased by 20%
12) 15 is increased by 10. 10 is of 15, so 15 increased by %
13) 5% of 9,000 is 450. 450 + 9,000 is $9,450
14) 7% of 140 is is 9.8. 140 + 9.8 = $149.8
15) 6% of 225 is 13.5. 225 + 13.5 = $238.5
The equation can be written as:
4 + 5 / 2
Remember to follow PEMDAS.
4 + 5 / 2
4 + 2.5
6.5
Best of Luck!
Answer:
The diver will be in free fall for 
seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function 
.

Therefore, 
⇒ 
⇒ 
seconds.
Therefore, the diver will be in free fall for seconds. (Answer)
