Answers
Answer:
18
Step-by-step explanation:
First, you would do a proportion
[tex]\frac{3}{50}[/tex]=[tex]\frac{x}{300}[/tex]
Then you would cross multiply, getting 50x=900.
After that, you would do 900/50, which is 18.
To paint 300 feet of fence we need 18 quarts of paint.

What is the inverse of the function shown( in the form of a graph)
Answers
Answer:
[tex] y = - 1x + b[/tex]
Step-by-step explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.
[tex] - \frac{1}{m} x[/tex]
m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
[tex] - \frac{1}{1} x \\ - 1x[/tex]
So the inverse slope would be -1.

Answers
Answer:
4 + y = 96 = 100
y = 104 - 4 = 100
4 y = 25 = 100 4 + 100 = y = 104
100 = y = 105 - 5
Step-by-step explanation:
Plz mark me as brainliest have a good day
The equations could you solve using the addition property of equality is
y- 4 = 100.
We have to apply the property of addition equality
Now,
4 + y = 100
y= 96
and, y -4 = 100
y = 104
and, 4 y = 100
y= 25
and, 100 = y - 5
y= 105
Thus, the required equality is y- 4 = 100.

The height h, in feet of a model rocket t seconds after launch is given
by the equation h= 245t - 16t?. As the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Express your final answer to the nearest tenth place.
What is the maximum height of the rocket?
Answers
Answer:
h_max = 324.09 ft
Step-by-step explanation:
The correct equation is;
h = 245t - 16t²
We are told that as the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Thus;
245t - 16t² = 325
Thus;
16t² - 245t + 325 = 0
Using quadratic formula, we have the roots as;
t = 1.47s or 13.85s
We will pick the higher value.
Thus;
Maximum height will occur at t = 13.85 s
Thus, plugging in 13.85 for t into h = 245t - 16t², we have;
h_max = 245(13.85) - 16(13.85)²
h_max = 324.09 ft
