Answer:
x = - 6
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 9 when x = 3, thus
k = 
= 
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
Percentage of students with GPA between 1.5 and 3.5 is 75% and Percentage of students that don't belong to freshmen is 73.9%.
<h3>How to Calculate the Percentage?</h3>
1) Total number of households with computer = 111,804
Percentage of Cincinnati households with computer = 82.1%
Thus;
Number of Cincinnati households with computer = 82.1% * 111804 ≈ 91791
2) Total number of students = 854
Percentage of students with GPA between 1.5 and 3.5 = 100 - (11 + 14) = 75%
3) Total number of students = 854
Number of freshmen = 223
Thus;
Percentage of students that don't belong to freshmen = 1 - (223/854) = 1 - 0.2611 = 0.7389 ≈ 73.9%
4) We are given;
17% of the 198 seniors are on Academic Watch
10% of 223 freshmen are on Academic watch
Thus;
a) seniors on academic watch = 17% * 198 ≈ 34
b) freshmen on academic watch = 10% * 223 ≈ 22
c) Number of more seniors that freshmen on academic watch = 34 - 22 = 12

Answer:
7 hours and 30 minutes
Step-by-step explanation:
because if you divide the 5 hours by the 2 people you get 2 hours and 30 minutes so if you add one more person you are basically adding 2 hours and 30 minutes so if u add that 2 hours and 30 minutes to the 5 hours you will get 7 hours and 30 minutes

cones radius is 24/2=12
we have to find cones height
use Pythagorean
h^2+12^2=37^2
h =35
V=pi.r^2.h/3
V=3.14.12^2.35/3
V=5275.2
Answer:
If the problem is,
By finding it,
Take a 5 box grid in which each box represents 1 unit,
Then take 1 box of this grid,
Repeat this step,
Finally, Add them,
We get,
A grid having 10 boxes with 2 taken boxes,
Thus, 
When we do these steps for three grids we will get 
,
That is, by multiplying the result of 
by 3 we will obtain
