Answer:

87 3/4

Step-by-step explanation:

If the manufacturer also sells a small-size box that has a volume that is 3/10 of the volume of the regular-size box, then the volume of the small-size box of dog treats would be 87 3/4.

To determine the volume of the box, we would first convert the measurements of the regular-size boxes to a proper fraction. We could proceed as follows:

3 1/4 inches = 13/4

7 1/2 inches = 15/2

12 inches

Now we sum the volumes as follows: (13/4) * (15/2) * (12/1)

= 585/2 cubic inches

Now, we would find 3/10 of  585/2 cubic inches

= 87.75 inches or 87 3/4 cubic inches.

Answer:

(A) 113.04^2

Step-by-step explanation:

Area of a circle is found with: πr^2

in this we will replace π with 3.14

the radius is 6feet

first step: 6^2 = 36

second step:  3.14*36= 113.04^2

Step-by-step explanation:The given graph is a line graph, represents increasing and decreasing rainfall in six different years.The given graph misleads ,in terms of length, when amount of rainfall 4.6-3.9 is plotted with six different years 2006-2011. When rainfall decreases from 4.5 to 4.4, the decrease , in length of rectangle is less,should be equal, in comparison to when year increases from 2006 to 2007. It must be in the shape of Square.
Part B if instead of line graph, we will draw bar graph ,representing Amount of rainfall(4.5-3.0) on y axis in the month of July, to 6 different years from (2006-2011) on x axis,i think it will be least misleading.

Explanation:

Volume of triangular prism = 1/2 × Base × Height × Length

Identify the following:

Find Volume:

[tex]Area \: of \: triangle = ½ × height× width \\ area = \frac{1}{2} \times 8 \times \frac{20}{3} \\ area = \frac{{ \cancel8} {}^{ \: \: 4} }{ \cancel2} \times \frac{20}{3} \\ area = \frac{80}{3} {ft}^{2} [/tex]

Now for volume :-

Volume = area of triangle (2D ) × length

[tex]volume = area \times length \\ vol = \frac{80}{3} \times 12 \\ vol = \frac{80}{ \cancel3} \times { \cancel{12}} {}^{ \: \: 4} \\ volume = 320 {ft}^{3} [/tex]

Answer:

Main part of backpack V = 840 inᶾ

Front pocket of backpack V = 64 inᶾ

Top curve of the backpack V = 395.8406744 inᶾ

Total V = 1299.840674 inᶾ

Step-by-step explanation:

1.

As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl).  We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket).  As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h).  We will use this formula to find the volume of the half cylinder (top curve of the backpack).

2.

For the large rectangular prism (main part of the backpack), we are given:

w = 7in

h = 10in

l = 12in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V = whl

V = 7 x 10 x 12

V = 840 inᶾ

3.

Now for the smaller rectangular prism (front pocket of backpack), we are given:

w = 2in

h = 4in

l = 8in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V = whl

V = 2 x 4 x 8

V = 64 inᶾ

4.

Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder.  We are given:

r = 6in

h (which will be the same as the width of the backpack in this case scenario) = 7in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V* = πr^2h

V* = π x 6^2 x 7

V* = 791.6813487 inᶾ (round this number if you must)

Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.

V = V*/2

V = 791.6813487/2

V = 395.8406744 inᶾ (round this number if you must)

5.

Finally, we can add our volumes together to acquire the volume of the backpack as a whole!

Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)

Recall that:

Large rectangular prism (bottom part of the backpack) = 840 inᶾ

Smaller rectangular prism (the pocket) = 64 inᶾ

Half cylinder (top curve of the backpack) = 395.8406744 inᶾ

So:

Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ

Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)

Answer:

451.61

Step-by-step explanation:

1) Set a linear equaion

[tex] \frac{98}{x} = \frac{21.70}{100} [/tex]

2) Cross multiply

[tex]21.70x = 98 \times 100[/tex]

3) Multiple the right side

[tex]21.70x = 9800[/tex]

4) Divide both side by 21.70

[tex] \frac{21.70x}{21.70} = \frac{9800}{21.70} [/tex]

5) Solve the linear equation

[tex]x = 451.6129032[/tex]

[tex]x≈451.61[/tex]

Then 21.70% of 451.61 is 98

Answer:

The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.

Step-by-step explanation:

Let pencils be p

Let crayons be c

6 pencils and 5 crayons are 37.5 inches. This will be:

6p + 5c = 37.5 ........ equation 1

7 pencils and 6 crayons are 44.1 inches. This will be:

7p + 6c = 44.1 ........ equation 2

Multiply equation 1 by 7

Multiply equation 2 by 6

42p + 35c = 262.5 (3)

42p + 36c = 264.6 (4)

Subtract 4 from 3

c = 2.1

Plug the value of c into equation 1

From equation 1

6p + 5c = 37.5

6p + 5(2.1) = 37.5

6p + 10.5 = 37.5

6p = 37.5- 10.5

6p = 27

p = 27/6

p = 4.5
