Determine the percent change from 30$ to 75$
1 answer:
150%
(new value-old value/old value)*100 is the formula
so if you plug it in
(75-30/30)*100
75-30=45/30=1.5*100=150

Answer:
11.8
Step-by-step explanation:
3(12.4) + 6(11.5) = 37.2 + 69 = 106.2
106.2/9 = 11.8
The answer to this question would be 4
- Here, t represents time, which is the input of the function, so we know that 10 is the time in minutes.
- h(t) represents the altitude, which is the output of the function after time, t.
- So, we need to substitute 10 into 210 -15t in place of t.
- On simplifying 210 -15(10), we get that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.
0.25=25/100=1/4. 1/4×84=84/4=21. The answer is 21
