Answer: 384 feet

Step-by-step explanation:

     We will simplify and solve -16t² + 160t when t is equal to 4.

-16t² + 160t

-16(4)² + 160(4)

Answer:

Step-by-step explanation:

**Note: The polynomial in question is -16t² + 160t, as clarified in the discussion under the question.**

Since there is a polynomial to find the height given a certain time, the height is a function of time.

This function would be h(t) = -16t² + 160t, so plugging in 4 for t would give the height.

h(4) = -16(4)^2+160(4)

-16(16)+160(4) <em>[Squaring 4]</em>

<em />-256 + 640 <em>[Multiplying]</em>

<em />384 <em>[Combining both terms]</em>

Hence, the <u>height</u> of the firework after 4 seconds is 384 feet.

- Hose A fills a water truck at the constant rate of 60 gallons every 15 minutes. Hose B fills a water truck at a constant rate
joja [24]

Answer:

"The rate of Hose A is 1 gallon per minute more than the rate of Hose B"

Step-by-step explanation:

Hose A:

60 gallons every 15 minutes means

60/15 = 4 gallons per minute

Hose B:

y = 3x

y is gallons

x is minutes

we put x = 1 and get:

y = 3*1 = 3

That means 3 gallons per minute

Thus,

the correct choice is C), or third option. 4 is 1 greater than 3 so Hose A is 1 gallons per minute more than the rate of Hose B.

A recipe for oatmeal cookies makes 24 cookies. The recipe calls for 2 1/2 cups of flour. Penny wants to make 3/4 of the recipe.
barxatty [35]

Answer:

Penny needs 1\frac{7}{8} cups of flour to make 3/4 of the recipe.

The recipe will make 18 cookies.

Step-by-step explanation:

We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.

To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:

\frac{3}{4}\text{ of recipe}=24\times \frac{3}{4}

\frac{3}{4}\text{ of recipe}=6\times \frac{3}{1}

\frac{3}{4}\text{ of recipe}=18

Therefore, the recipe will make 18 cookies.

We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:

\text{Cups of flour needed to make 3/4 of recipe}=2\frac{1}{2}\times \frac{3}{4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{5}{2}\times \frac{3}{4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{5\times 3}{2\times 4}

\text{Cups of flour needed to make 3/4 of recipe}=\frac{15}{8}

\text{Cups of flour needed to make 3/4 of recipe}=1\frac{7}{8}

Therefore, Penny needs 1\frac{7}{8} cups of flour to make 3/4 of the recipe.
