Answer:

$39 per square foot.

Step-by-step explanation:

The cylinder has a height of 2 feet and a radius of 5 feet.

The total cost of the metal will be (assuming US dollars) $8572.20.

And we want to determine the cost per square foot.

First, we can find the surface area of the cylinder. The surface area for a cylinder is given by the formula:

[tex]SA=2\pi r^2+2\pi rh[/tex]

Where r is the radius and h is the height.

Since the radius is 5 feet and the height is 2 feet and using 3.14 for π, the surface area is:

[tex]SA=2(3.14)(5)^2+2(3.14)(5)(2) =219.8\text{ feet}^2[/tex]

Therefore, to find the cost of metal per square foot, we can divide the total cost over the amount of surface area. Hence:

[tex]8572.20 / 219.8= \$ 39 \text{ per square foot}[/tex]

So, the metal costs $39 per square foot.

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

6 11/12 = 72/12 + 11/12 = 83/12

2 4/16 = 2¼ = 8/4 + 1/4 = 9/4

3⅔  = 9/3 + ⅔ = 11/3

Fractions need a common denominator to be added or subtracted.

Answer:

13/24

Step-by-step explanation:

First, it would be easier to find the common denominator of 1/3 and 1/8. The easiest way to do that is to do 3x8=24. This means the common denominator is 24 and so we must convert the fractions so they have this denominator.

1/3 --> 8/24

1/8 --> 3/24

Now, we can simply add these fractions together to find out the fraction of songs that are NOT country songs.

8/24 + 3/24 = 11/24 songs are not country songs.

To find out the fraction of songs that are country, simply do 1 (or 24/24) take away 11/24.

24/24 - 11/24 = 13/24 songs are country songs.

Answer:

The total amount of granola bars ordered were 840 granola bars.

Step-by-step explanation:

Multiply 35 by 24.

If Mr. Kowolski ordered 35 boxes of granola bars and Eoch box contained 24 granola bors then 840 is the total number of granola bars Mr. Kowolski ordered.

Two or more expressions with an Equal sign is called as Equation.

Given that Mr. Kowolski ordered 35 boxes of granola bars.

Each box contained 24 granola bors.

We need to find the total number of granola bars Mr. Kowolski ordered.

To find this we have to multiply thirty five with twenty four.

Multiplication is a method of finding the product of two or more numbers

35×24

We get eight hundred forty

840

Hence, 840 is the  total number of granola bars Mr. Kowolski ordered.

Answer:

10 Quarters and 5 dimes

Step-by-step explanation:

10 Quarters = $2.50

5 dime = $0.50

Answer:

20 dimes and 4 quarters

Step-by-step explanation:

So, a dime is 10 cents and a quarter is 25

So, let's say you have x dimes and y quarters

X+Y=24 (total amount of coins)

Also,

10x+25y= 300 (cents)

I just put the 3 dollars into cents

Now, you have a system of equations and we should solve it:

X+y=24 ----x=24-y

10x+25y=300

So substitute x in the 2nd equation

10(24-y)+25y=300

240-10y+25y=300

240+15y=300

15y=60

y=4

Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20

So, 4 quarters and 20 dimes

Check:

20 dimes=2 dollars

4 quarters= 1 dollar

correct

Answer:

125 degrees.

Step-by-step explanation:

L is the midpoint of NK so the arcs NM and Mk are equal.

So MK = 55 degrees and the arcs JN and JK are equal

Therefore  

JK =

(360 - 2*55)/2

= (360 - 110) / 2

= 250 /2

= 125 degrees.
