Answer:
Step-by-step explanation:
Need to find the value of t, when h(t) = 0
-
-16t^2 +64t + 100 = 0
- 4t^2 - 16t - 25 = 0
- 4t^2 - 2*2t*4 + 16 = 41
- (2t - 4)^2 = 41
- 2t - 4 = √41
- 2t - 4 = 6.4
- 2t = 10.4
- t = 5.2
Answer is 5.2 seconds
Answer:
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
Explanations:
Number of snicker bars = 6
Number of cookies = 5
Total = 6 + 5 = 11
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
X = 5/14 I believe is the answer
It is equal to 63.
Hope this helped☺☺
It would be 220 because 20 students in all, 20×20 is the 400 students. so if you just multiplied the 9 and 11 by 20, it would match up with 400 students and you would have 220 girls. (This is not how most people work this out, but I hope it helped).
