Lana has a memory box that measures 18 inches wide by 9 inches deep. The height is 1.5 feet what is the volume of the box. IN INCHES!!!!!!!

Answers

Answer:

2916

Step-by-step explanation:

1.5 feet is 1 foot 6 inches, or 18 inches

volume is height * length * width, so 18 * 9 * 18 = 2916

Answer:

2,916 inches

Step-by-step explanation:

The formula for volume is length x width x height.

So, you will have to start to identify each of these.

First, though, because of 1.5 being feet and not inches, you must convert.

1 foot = 12 inches, so 1/2 foot = 6 inches. Meaning, 12 + 6, which is 18 inches.

Now, you can solve: 18 x 18 x 9 = 2,916.

A 9-inch diameter pizza has 30 calories per square inch. About how many calories are in the entire pizza?
Use 3.14 for pi.

Answers

Answer:

113.04 calories

Step-by-step explanation:

please mark answer as brainlest

The whole pizza will have 1908 calories.

What is area?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area.

Given that, a 9-inch pizza has 30 calories per inch² we need to find that how many calories are in the entire pizza,

For finding the same we will find the area of the pizza,

Area = π × radius²

= 3.14 × 4.5²

= 63.6

Therefore, the area of the pizza is 63.6 in²

Since, 1 in² = 30 calories

So, 63.6 in² = 30 × 63.6 = 1908 calories.

Hence the whole pizza will have 1908 calories.

Ella wants to make a fruit salad for herself and 5 friends.

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

1. How many cups of fruit salad does Ella have?

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person
1.) 15 cups
2.) 3 cups per person

Answers

Answer:

4/11

Step-by-step explanation:

there are 4 green out of 11 total

Answer:

B.

Step-by-step explanation:

First, you will need to find out how many marbles there are total, which is 11. After doing so, you are able to eliminate two of your answer choices already (C. and D.). Next, identify how many green marbles are in there, which is 4. You are able to identify that A. can be eliminated as well. With you finding probability, the total amount will be on the bottom. So, you can see that there is a 4/11 or about 36% chance that a green marble will be picked.

Answers

Answer:

7. D) 180

7. C) 24%

7. D) 2 out of 9

7. D

Step-by-step explanation:

36 doesn't go into 5

45 doesn't go into 4

60 doesn't go into 9

180/4 = 45

180/3 = 60

180/5 = 36

180/9 = 20

We can make this problem even easier by converting the denominator from 25 to 100. This can be done with multiplication (x4)

Whatever you do to the denominator, you must also do to the numerator, so if we multiply both sides by 4, we get 24/100, which is equivalent to .24

total: 81 pieces of jewelry

18/81 or 2/9 (divide numerator and denominator both by 9)

.67 = 67/100

.607 = 607/1000 or 60.7/100

Part C: Greg had a rectangular vegetable garden that was 4 feet wide by 5 feet long. He increased the length of his garden by 2 feet and doubled the width. How many square feet larger is the area of his new garden compared to the area of his old garden? In a short paragraph, explain your answer in your own words.

Answers

part a: c. 96 square feet

part b: 60 inches

part c: 36 square feet


explanation: I multiplied 4 and 5 because area = l•w meaning the garden was originally 20 square feet. I then doubled the making it 8 and added two feet to the length making it 7 feet. Since area equals l•w i multiplied 8 and 7 getting 56 square feet. Since the question asked, “how many square feet larger,” I subtracted the new area, 56 square feet, by the old one, 20 square feet, and got 36 square feet.

13: what is the measure of angle y?

14: what is the measure of angle x?

15: what is the measure of angle z?

Answers

angle y and the angle measuring 76 degrees are opposite so they should be equal. this means angle y = 76 degrees.

angle x + angle measuring 76 degrees should = 180 (they are supplementary angles)

x + 76 = 180

180 - 76 = x

x = 104 degrees

angle z is opposite angle x so they are equal. angle z = 104 degrees

y is 76 because it’s vertical to the degree given and then z and x is 180-76 which equals 104. z and x are the same because they are vertical to each other
