To find the ratio of girls to boys, you first will subtract 176-96. This will give you 80, which now leads you to the next step. Now since you have the amount of guys you have the solution to the final ratio. 96:80 is the ratio of girls to boys, simplified the ratio is 6:5.
Okee dokee, 9/10*3 1/3, so first, you need to change 3 1/3 from a mixed number to a fraction, which is 10/3, then all the steps is below:
9/10*10/3 => 9*10/10*3 => 90/30 => 3
The correct answer is 3.
The answer is B because you have a positive slope (m in y = mx + b) so that eliminates C and D. And you have a positive y-intercept (b in y = mx + b). This eliminates option A as well, which leaves you with option B.
The equation for the red graph is f(x) = -x².
<h3>How to depict the equation?</h3>
From the information given, g(x) = 4 - x².
The vertex of the point (0, 4) and (0, 0) for g(x) and f(x) respectively. The rule of the translation will be:
(x, y) = (x, y -4).
The equation of the function will be:
f(x) = g(x) - 4
f(x) = (4 - x²) - 4
f(x) = -x²

The number of months overcharged for 1 gallon of leaky water = 1 1/3
= 4/3
Let us assume the quantity of water overcharged = w
Let us assume the time in months = t
Then, the equation modelling this direct variation is
w = (3/4)t
When w = 5, then
5 = (3/4) * t
20 = 3t
t = 20/3
= 6 2/3
From the above deduction, we can conclude that the first option or option "A" is the correct option. I hope the answer helps you.
