Anthony is building a cube-shaped box to store some of his smaller crafting supplies. The formula for the surface area of a cube is SA=6s2, where s is the side length of the cube. If he has a total of 200 in.2 of cardboard, can Anthony build a box where s=6 in.?

No, he needs 16 in.2 more cardboard.

No, he needs 232 in.2 more cardboard.

Yes, he will have 56 in.2 of cardboard left over.

Yes, he will have 128 in.2 of cardboard left over

Answers

Answer:

No, he needs 16 inches^2 more cardboard.

Step-by-step explanation:

Take the formula and substitute values into it. 6 * 6^2

Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.

No he needs 16 in 2 more cardboard

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal have they raised?

Answers

Answer: 64%

Step-by-step explanation:

The band needs $800 for new uniforms and of that, they only raised $512.

Set up a proportion [tex]\frac{part}{total} = \frac{percentage}{100}[/tex]and plug everything you know in.

[tex]\frac{512}{800}[/tex] = [tex]\frac{x}{100}[/tex]

Solve for x by cross multiplying and dividing.

512 × 100 = 51200

51200 ÷ 800 = 64

x = 64

The school band has raised 64% of their goal already.

Answer:

The Answer would be 64%

Step-by-step explanation:

You are given the equation y=5-4x. You can put that into slope intercept form.  Slope intercept form is y=mx+b where b is the y intercept and m is the slope. In this equation the slope is -4 and the y intercept is 5. You can  rearrange this equation into slope intercept form. If you do this you will get y=-4x+5.

Answers

a) 20.9

    The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.

    First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!

b) 30

To figure this out, we will set up an equation that looks like this:

[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]

And now we will solve:

[multiply both sides by 12] 230 + x = 264

[subtract 130 from both sides] x = 30

So the age of the new player should be 30!

Have a nice day!
