Each pad of paper cost 3.25. Here is how I found it.

21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25

X = 3.25

Is this what you were looking for?

If staplers cost 21.75 each and there’s 3, you would need to do 21.75x3=65.25
You have 9.75 left for pads of paper and there’s 3 so 9.75/3=3.25

Each pad of paper costs $3.25 or x=3.25
Hope this helped!

Answer: Third option.

Step-by-step explanation:

You know that:

\frac{Area\ of\ sector}{Area\ of\ circle}=\frac{n}{360\°}

Where "n" is the Central angle measured in degrees.

In this case, let be:

Area\ of\ sector=A_s\\Area\ of\ Circle=A_c

Rewriting the formula:

\frac{A_s}{A_c}=\frac{n}{360\°}

Now, you need to solve for A_c:

A_s=(\frac{n}{360\°})(A_c)\\\\A_c=(A_s)(\frac{360\°}{n})

Given the data shown in the picture attached, you can identify that:

A=A_s=6\pi \ in^2\\\\n=40\°

Then, you can substitute these values into the equation (Use \pi =3.14):

A_c=(6*3.14\ in^2)(\frac{360\°}{40\°})\\\\A_c=169.56\ in^2\\\\A_c\approx170\ in^2

Therefore, the entire mirror will cover 170\ in^2

Identify the volume and surface area of the sphere in terms of π. HELP PLEASE!!
Helen [10]

Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Step-by-step explanation:

Start with the two formulas:

Volume of a circle:

V = \dfrac{4}{3} \pi r^3

Surface area of a circle:

S = 4 \pi r^2

Now use r = 24 m in each formula.

Volume:

V = \dfrac{4}{3} \pi (24~m)^3

V = \dfrac{4}{3} \pi (13,824~m^3)

V = 18,432\pi~m^3

Surface area:

S = 4 \pi r^2

S = 4 \pi (24~m)^2

S = 4 \pi (576~m^2)

S = 2,304\pi ~m^2

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

1, I cannot fail this if I do I have a F in math!! Please make sure u know it’s correct I can’t do it alone.
Anton [14]

Answer:One way of knowing the correct answers, we substitute the ordered pairs to the function and see whether it would make the function true.

3x – 4y = 21

A. (−3, 3)

3(-3) – 4(3) = 21

-21 = 21 ---------------> not equal

B. (−1, −6)

3(-1) – 4(-6) = 21

21 = 21 ---------------> equal

C. (7, 0)

3(7) – 4(0) = 21

21 = 21 ---------------> equal

D. (11, 3)

3(11) – 4(3) = 21

21 = 21 ---------------> equal
