Answer:

Step-by-step explanation:

In 30 minutes she can walk 2 miles. We'll put that as a ratio. 30:2. Now to figure out how much she walks in 45 minutes, we set variable to x and make it stand for how much she walks. We have 30:2 = 45:x We cross multiply to get 30x=90, x=3. Tara can walk 3 miles in 45 minutes.

92 = 11 + 12 + 13 + 2(a) + 4(3a)

92 = 36 + 2a + 12a

92 = 36 + 14a

-36 -36

56 = 14a

56/14 = 14a/14

a = 4

4. To solve this problem, we must simply subtract the volume of the smaller box from the volume of the larger box. The formula for volume of a rectangular prism is length * width * height. So we know that the bigger box has a height of 20 inches, a length of 15 inches, and a height of 9 inches. We can multiply these together to get the volume.

20 * 15 = 300

300 * 9 = 2700

The bigger box has a volume of 2,700 cubic inches.

Now for the smaller box. This box has a length of 12 inches, a width of 8 inches, and a height of 4 inches. Let us multiply this together:

12 * 8 = 96

96 * 4 = 384

The smaller box has a volume of 384 cubic inches.

Now, we just need to subtract.

2700 - 384 = 2316

There are 2,316 cubic inches of space left in Jeff's bigger box.

5. Mrs. Nelson has plans for a flower box that has two constant side lengths, the length and height (5 feet and 2 feet). The width can be any whole number (counting number) only up to 5 feet, so there are 5 different volumes she could have. Those are:

5 * 2 * 1 = 10 cubic feet

5 * 2 * 2 = 20 cubic feet

5 * 2 * 3 = 30 cubic feet

5 * 2 * 4 = 40 cubic feet

and

5 * 2 * 5 = 50 cubic feet

The possible volumes for Mrs. Nelson's flower box are 10, 20, 30, 40, and 50 cubic feet.

So there you have it!
Hope that helped! =)
