Answer is C).

One way to find the answer is to multiply the $54 by .30 (which is 30%converted to a decimal). Doing this will give you what 30% of $54 is.
This gives you 16.2
Since the question is asking what 30% off the price is, subtract the 16.2 from the $54.

Answer:

A. This passage is written incorrectly.

Why?

The reason for this is when you have quotation marks, you must put the punctuation inside the quotes.

How should the passage be written?

The passage should be written like this:

"Did you finish your homework?" Forrest asked.

"I have to write a summary of the book after I finish it," Jeff answered.

"I will leave you to it,"said Forrest. "By the way, its an exciting story," he added.

Instead of.....

"Happy Birthday, Rachel"! Lily cried.

its...

"Happy Birthday, Rachel!" Lily cried.

Instead of.....

Rachel replied sadly "Its been a horrible birthday".

its.......

Rachel replied sadly, "Its been a horrible birthday."

Instead of.....

"Why, Rachel? Its not supposed to be, right"? Lily said, surprised.

its..........

"Why, Rachel? Its not supposed to be, right?" Lily said, surprised.

*Note: I am dreadfully sorry for the typos. Hope this helps!!!

Ava and Kelly ran a road race, starting from the same place at the same time. Ava ran at an average speed of 6 miles per hour. K

zalisa [80]

<h2>Hello!</h2>

The answer is:

It will took 0.375 hours for Ava and Kelly to be 3/4 miles apart.

To calculate how long after they start they will be 3/4 miles apart, we need to write two equations.

So, writing the equations, we have:

Calculations for Ava:

We have the following information,

$v_{Ava}=6mph$

Then, writing the equation,

$x_{Ava}=x_{o}+v_{Ava}*t$

$x_{Ava}=x_{o}+v_{6mph}*t$

Calculations for Kelly:

We have the following information,

$v_{Kelly}=8mph$

We need to calculate when Kelly will be 3/4 miles apart of Ava, so, it's position will be the Ava's position plus 3/4 miles.

Then, writing the equation,

$x_{Ava}+0.75miles=x_{o}+v_{Kelly}*t$

$x_{Ava}+0.75miles=x_{o}+v_{8mph}*t$

Now, substituting Ava's speed into the second equation, we have:

$x_{o}+6mph*t+0.75miles=x_{o}+8mph*t$

$6mph*t+0.75miles=+8mph*t$

$8mph*t-6mph*t=0.75miles$

$2mph*t=0.75miles$

$t=\frac{0.75miles}{2mph}=0.375hours$

Hence, we have that it will took 0.375 hours for Ava and Kelly to be 3/4 miles apart.

Have a nice day!

Kenzie has. 4 pages of homework to do. If she can finish 1/3 of a page in one hour how many hours will her homework take?

Maru [420]

Answer:

It will take her 4 1/3 hours

Step-by-step explanation: so you know you needed to add 4 and 1/3 and you turn the 4 into 4/1 and 1/3 and since it adding you have to have the same denominator and you multiply 1x3 and if you do it on the bottom you have to do it on top so you also do 4x3 and 4x3 is 12 and one 1x3 is 3 and so you don't have to have to do it on the other fraction because now they have the same denominator now and now you add 12/3 + 1/3 and you shall get 13/3 and then you divide 13 divided by 3 and you shall get 4 1/3 and that shall be your answer.

hope it helps you!

The graph shows the functions f(x), p(x), and g(x):

Kruka [31]

Two functions have equal values where their graphs cross.

A) The solution to the pair of equations
.. y = p(x)
.. y = f(x)
will be where the graphs intersect, at (x, y) = (-3, -3).

B) We already know that (-3, -3) is one solution to y=f(x). The graph also appears to go through the point (0, 0).

C) p(x) = g(x) where their graphs cross, at x = -6. Both functions have the value 1 for that value of x.
