Step-by-step explanation:

If they charge 0.50 cents per ounce then u would take the 50 cents and add that up until it gets to 3.50 and that will give u 7 so the answer is 7 ounces.

Answer:

1. V≈1244.07

2. V≈54286.72

3.V≈23816.41

4. V≈254.47

5. V≈4247.43

6. V≈21714.69

7. V≈4712.39

Step-by-step explanation:

use the formula V=πr^2h

The volume of the given cylinders is 1. V≈1244.07 2. V≈54286.72 3. V≈23816.41 4. V≈254.47 5. V≈4247.43 6. V≈21714.69 7. V≈4712.39.

The volume of the cylinder is the product of the height, pie, and square of the radius.

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

A.

a) The height of the cylinder is given as 11 in and the radius is 6 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 6^2 x 11

                                                    = 1244.07cubics in

b)  The height of the cylinder is given as 30 in and the radius is 24 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 24^2 x 30

                                                    = 54286.72 cubics in

c) The height of the cylinder is given as 21 in.

The radius of the base of the cylinder is given as 19 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 19^2 x 21

                                                    = 23816.41 cubics in

B.

d) The height of the cylinder is 9ft the radius is 3 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 3^2 x 9

                                                    = 254.47 cubics ft

e) The height of the cylinder is 8 ft the radius is 13 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 13^2 x 8

                                                    = 4247.43 cubics ft

f) The height of the cylinder is 27 ft the radius is 16 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 16^2 x 27

                                                    = 21714.69 cubics ft

g) The height of the cylinder is 15 ft the radius is 10 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 10^2 x 15

                                                    = 4712.39 cubics ft

Answer: 8

Step-by-step explanation:

Let the number be represented by x.

Two less than three times a number is the same as six more than twice the number. This will be:

(3 × x) - 2 = (2 × x) + 6

3x - 2 = 2x + 6

Collect like terms.

3x - 2x = 6 + 2

x = 8.

The number is 8

Answer:

The volume of a box is:

V = 560 cubic inches or  [tex]20\frac{20}{27}[/tex]  cubic inches.

Step-by-step explanation:

Given

The width of a box = w = 2 2/3 inches

i.e. [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex]

The length of a box = l = 3 1/3 inches

i.e. [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex]

The height of a box = h = 2 1/3 inches

i.e. [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex]

Using the formula to determine the volume of a box

[tex]V=w\times l\times h[/tex]

substitute  [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex],   [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex]  and  [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex],  

[tex]V=\frac{8}{3}\times \frac{10}{3}\times \frac{7}{3}[/tex]

Apply the fraction rule:  [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]

   [tex]=\frac{8\times \:10\times \:7}{3\times \:3\times \:3}[/tex]

   [tex]=\frac{560}{27}[/tex]   or   [tex]20\frac{20}{27}[/tex]  cubic inches

Therefore, the volume of a box is:

V = 560 cubic inches or  [tex]20\frac{20}{27}[/tex]  cubic inches.

Answer:

20 tshirts and 150 keychains

Step-by-step explanation:

let tshirts be 10x and keychains be 2y

now make a Quadratic equation,

10x+2y=500

=let x = 20

=(10×20)+2y=500

=200+2y=500

=2y=300

y=300/2 = 150

therefore 20 tshirts and 150 keychains sumsup their goal of 500 dollars

Answer:

3.33%

Step-by-step explanation:

Given that :

Final amount A= 320

Principal P = 300

Time (t) = 2 years

Yes, the information is enough to obtain the interest rate :

Using the relation :

A = P(1 + rt)

r = interest rate

320 = 300(1 + r*2)

320 = 300(1 + 2r)

320/300 = 1 + 2r

1.0666666 = 1 + 2r

1.0666666 - 1 = 2r

0.0666666 = 2r

r = 0.0666666 / 2

r = 0.0333333

(0.0333333) * 100% = 3.33%

Based on the information given the interest rate is 53.33%.

Amount= Principal× Interest rate ×Time/100

Let r represent the interest rate

Hence:

320 = 300×r×2 years/100

320×100/300×2=r

r=320/3×2

r=160/3

r=53.33 or 53 1/3

Inconclusion  the interest rate is 53.33%.
