Ava is buying paint from Amazon. Ava needs 3⁄4 cup of blue paint for every 1 cup of white paint. Ava has 28 ounces of white pain

Drupady [299]

Answer:

21

Step-by-step explanation:

So we know the ratio is 3/4:1

So if she has 28 ounces of white pain, we can do 28*3/4=21. You could also do 28/4 (find out how much 1/4 of the value is) which is 7 and then multiply that by 3. What your basically doing is your putting it into 4 equal parts and then just multiplying by 3 since that's the amount of parts you need/have.

Graph the inequality on the numberline and then write it in interval notation. 4-3y<-8

pogonyaev

First, let's simplify the inequality

$\begin{gathered} \frac{4}{3}y$

The graph looks like this:

Notice that the white dot is placed above the -6, it is important to include it like that.

Now, as an interval:

$\begin{gathered} y$

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (4, 3)

Point (-2, 1)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute: $m=\frac{1-3}{-2-4}$
Subtract: $m=\frac{-2}{-6}$
Simplify: $m=\frac{1}{3}$

Answer:

$t= 6\ s$

Step-by-step explanation:

We know that the equation that models the height of the ball as a function of time is $h(t) = -16t ^ 2 + 80t + 96$ .

Where the initial speed is 80 feet.

When the ball lands on the ground, its height will be $h(t) = 0$ .

So to know how long it will take the ball to reach the ground, equal h (t) to zero and solve for t.

$-16t ^ 2 + 80t + 96 = 0$

To solve this quadratic equation we use the quadratic formula.

For an equation of the form:

$at^2 +bt +c$

The quadratic formula is:

$t=\frac{-b\±\sqrt{b^2 -4ac}}{2a}$

In this case

$a =-16\\b = 80\\c =96$

Then

$t=\frac{-80\±\sqrt{80^2 -4(-16)(96)}}{2(-16)}$

$t_1=-1\\\\t_2=6$

We take the positive solution

$t= 6\ s$
