Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) =3x - 8 and g(x) = x² + 4
- f(g(- 2)) = ?
<u>First find g(- 2):</u>
- g(- 2) = (-2)² + 4 = 4 + 4 = 8
<u>Find f(8):</u>
- f(8) = 3*8 - 8 = 24 - 8 = 16
Answer:
2:3 unless it wants it in total, then 220:330
Step-by-step explanation:
it gives you the answer with the fraction. A ratio is basically saying with x:y for every x number of one thing there are y number of another. In this case we know 2/5 will be green, so how many will be red? 3/5. So for every 2 greens there are 3 reds.
Another way of looking at it is for the totals. there are 550 total, so 2/5 of that is green. 2/5 of 550 is 220, while 3/5 is 330 so that means of the 550, the ratio is 220:330. Kinda like simplifying fractions where 220/550 is the same thing as 2/5
16.36 times 9 which equals to 147.51 minutes
