The second graph

Step-by-step explanation:

Answer:

a). The volume of the pyramid on the left is greater by 2 inches cubed.

Step-by-step explanation:

The volume of a rectangular based pyramid is

V = [tex]\frac{1}{3}[/tex] w b h

Where w, and b are the lengths of the base of the pyramid, and h is the height of the pyramid

Substitute the values given for both pyramids into the equation, and solve for V

Left Pyramid:

V = [tex]\frac{1}{3}[/tex] w b h

V = [tex]\frac{1}{3}[/tex] * 7 * 6 * 3

Volume of Left Pyramid = 42 [tex]inches^{3}[/tex]

Right Pyramid:

V = [tex]\frac{1}{3}[/tex] w b h

V = [tex]\frac{1}{3}[/tex] * 4 * 3 * 10

Volume of Right Pyramid = 40 [tex]inches^{3}[/tex]

Subtract the two volumes to find the difference in volume

42 - 40 = 2 [tex]inches^{3}[/tex]

Answer:

The volume of the pyramid on the left is greater by 2 inches cubed.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Since this is right triangle, we can use the Pythagorean Theorem.

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

14 and 16 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.

14^2+16^2=x^2

Evaluate the exponents

196+256=x^2

Add

452=x^2

To get this is simplest radical form, find the greatest square root that divides evenly into 452

4 is the greatest square root. 4 times 113 equal 452

So, we have

[tex]\sqrt{4}\sqrt{113}[/tex]

Take the square root of 4

2[tex]\sqrt{113}[/tex]

So, choice D is correct.

Answer:

5 runners

Step-by-step explanation:

By looking at the graph, the number of runners in the 5-6 mile category is 5.

Answer:5

Step-by-step explanation:

Using the original scale of 2 inches = 5 feet, the living room is 20 feet wide. With the new scale of 1 inch = 44 feet, the width of the living room on the new blueprint would be 2.2 inches.

To solve this problem, one must first determine the actual width of the living room using the original scale. According to the original scale, 2 inches represent 5 feet. This would mean that the actual width of 8 inches would represent (8 / 2) * 5 = 20 feet. Now, set up a proportion with the new scale, which is 1 inch = 44 feet. If x is the width on the new blueprint, we would have x / 44 = 1 / 20, solving for x gives us x = 44 / 20 = 2.2 inches. Therefore, the width of the living room on the new blueprint would be 2.2 inches.

- 10 in, by 12 in. by 24 in.

- 12 in. by 15 in. by 18-in.

- 10 in. by 16 in. by 20 in.

- 12 in. by 12 in. by 20 in.

Answer:

The possible dimensions of the container are

- 10 in, by 12 in. by 24 in

- 12 in. by 12 in. by 20 in

Step-by-step explanation:

Given

Volume of the container = 2,880 cubic inches

Required

Possible dimensions of the container

To solve this question, the following assumption has to be made;

It'll be assumed that the container is a rectangular

To calculate the volume of a rectangular figure, we simply multiply the dimensions of the figure,

This implies that; we'll test each of the given options.

Which ever gives 2,880 is the right answer.

- 10 in, by 12 in. by 24 in.

[tex]Volume = 10 in * 12 in * 24 in[/tex]

[tex]Volume = 2,880[/tex] cubic inches

- 12 in. by 15 in. by 18-in.

[tex]Volume = 12 in * 15 in * 18 in[/tex]

[tex]Volume = 3,240[/tex] cubic inches

- 10 in. by 16 in. by 20 in.

[tex]Volume = 10 in * 16 in * 20 in[/tex]

[tex]Volume = 3,200[/tex] cubic inches

- 12 in. by 12 in. by 20 in.

[tex]Volume = 12 in * 12 in * 20 in[/tex]

[tex]Volume = 2,880[/tex] cubic inches

From the calculation above, only option A and D gives 2,880;

Hence, the possible dimensions of the container are

- 10 in, by 12 in. by 24 in

- 12 in. by 12 in. by 20 in

Given a volume of 2,880 cubic inches, one possible set of dimensions for a shipping container could be length = 24 inches, width = 15 inches, and height = 8 inches.

The volume of a rectangular container can be calculated by multiplying its length, width, and height. Given the volume of 2,880 cubic inches, we are looking for three numbers (dimensions) that, when multiplied together, equal 2,880.

One possible set of dimensions could be length = 24 inches, width = 15 inches, and height = 8 inches. Multiplying these dimensions together: 24 inches × 15 inches × 8 inches = 2,880 cubic inches, which matches the given volume of the container.

Step-by-step explanation:

6(a+3)=2a+30

Distribute

6a + 18 = 2a+30

Subtract 2a from each side

6a + 18 -2a= 2a+30-2a

4a  +18 =30

Subtract 18 from each side

4a+18-18 = 30-18

4a = 12

Divide each side by 4

4a/4 = 12/4

a = 3

We can factor by grouping

x^3 +6x^2      -2x-12

Factor x^2 out of the first group      and -2 out of the the second group

x^2 (x+6)  -2 (x+6)

Now factor out (x+6)

Step-by-step explanation \

Vm = Volume of the men's basketball

Vm = (4/3)*pi*r^3

Vm = (4/3)*pi*(5)^3 ... diameter = 10 --> radius = 10/2 = 5

Vm = 523.598775598299 cubic inches

Vw = Volume of the women's basketball

Vw = (4/3)*pi*r^3

Vw = (4/3)*pi*(4.5)^3 ... diameter = 9 --> radius = 9/2 = 4.5

Vw = 381.70350741116 cubic inches

Difference in volume = Vm - Vw

Difference in volume = 523.598775598299 - 381.70350741116

Difference in volume = 141.89526818714 cubic inches

Answer:

21.429 grams per day

Step-by-step explanation:

15g times 10 =150g

150g/7 =21.429g per day

Final answer:

A bird that eats 10 times its weight in food per week, with a weight of 15 g, consumes approximately 21.43 g of food per day.

Explanation:

If a bird weighing 15 g eats 10 times its weight in food in a week, we first calculate the total amount of food the bird eats in a week and then divide that by 7 to find the daily intake.

First, we calculate the weekly food consumption:

The bird's weight = 15 g

Total weekly food intake = 15 g × 10 = 150 g

Daily food intake = Total weekly intake ÷ 7

Daily food intake = 150 g ÷ 7 ≈ 21.43 g

Therefore, the bird eats approximately 21.43 grams of food per day.
