IF your equation is this: h(t)= -16t^2 + 27t + 7, then you set it equal to 17 and solve for t. What this does is tells you the times (t) when the ball is exactly 17 feet off the ground. Because this is a parabola, the ball will go up past the 17 foot mark, then pass it again on the way back down. This happens at .55 seconds (going up), and 1.13 seconds (coming down).

Step-by-step explanation:
The number of integers meeting the criteria can be found by counting them using a counting formula.
<h3>Divisible by 7</h3>
Integers divisible by 7 will have the form (7n), where n is some positive integer. The number of them less than 1000 can be found from ...
7n ≤ 1000
n ≤ 142.857
There are 142 integers less than 1000 that are divisible by 7.
<h3>Divisible by 7 and 11</h3>
Similarly, integers divisible by 7 and 11 will be of the form (77n), for some positive integer n.
77n ≤ 1000
n ≤ 12.987
There are 12 integers less than 1000 that are divisible by both 11 and 7.
<h3>Divisible by 7, not 11</h3>
The number of integers less than 1000 that are divisible by 7, but not 11, will be the difference of these numbers.
142 -12 = 130 integers divisible by 7, but not 11.
Answer:
7 : 8
Step-by-step explanation:
Here is the full question
150 adults complete survey 80 were women
write the ratio men:women
put it in its simplest form
Number of men that partook in the survey = 150 - 80 = 70
Ratio of men to women = 70 : 80
divide both numbers by 10
7 : 8
Find the mean, median and more for the following data sets. (15, 13, 19, 17, 25, 13, 23, 18, 19, 17, 21)
