A rectangular swimming pool has a length of 50 meters, a width of 30 meters, and a depth of 1.75 meters. What is the volume of water needed to fill the swimming pool?

___cubic meters

Answers

Answer:

2625 cubic meters

Step-by-step explanation:

the volume of a rectangle is V = length x width x height (depth in this case)

so, 50m x 30m x 1.75m = 2625m^3

2,625 cubic meters is the correct answer

Which of the following equations is an example of the Associative Property of Addition?

Answers

Answer: Choice B

(3+4) + 2 = 3 + (4+2)

=========================================

Explanation:

The general rule for the associative property of addition is

(a+b)+c = a+(b+c)

the a,b,c stay in the same order from left to right. The only thing that changes is the way we group the pair of terms. On the left side, we have a & b together with c left out. Then on the right side, we have b & c together with 'a' excluded.

Addition of any group of numbers can be done in any order, which is why this property is valid (though perhaps there's a more rigorous proof out there). For this specific problem, a = 3, b = 4, and c = 2.

Answer: I think the answer to your question is option B.

the median would decrease.

Answers

Answer:

1. Mean: 103

2. Median: 8

3. Mean would increase.

Step-by-step explanation:

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1,236

Then, 1,236/ 12 = 103

Therefore, our answer!

2. Put the numbers in order from least to greatest:

1, 6, 7, 8, 9, 11, 16

Cross out one on each side until you get to the middle.

3. Add up all original numbers to get a mean of: 2.7 and then add up all the numbers including six to get a mean of: 3.2 As you can see, the mean increased.

Hope this helps, good luck! :)

The Mean is 103 ,Median is 8 and Mean would increase

What is mean and median?

The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set.

The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number.

according to the question,

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1236

Then, 1236/ 12 = 103

Therefore, our answer

2. Put the numbers in order from least to greatest:

1, 6, 7, 8, 9, 11, 16

Cross out one on each side until you get to the middle.

Median is 8

3. Add up all original numbers to get a mean of: 2.7 and then add up all the numbers including six to get a mean of: 3.2 As you can see, the mean increased.

What is 1 inch to 6 feet

Answers

Answer:

6 feet 1 inches in cm =

185.42 cm

The scale “1 inch to 6 feet” is equivalent to the scale “1 to 72,” because there are 72 inches in 6 feet. The scale “1 to 100” would make a scale drawing that is smaller than the scale “1 to 72,” because each inch on the new drawing would represent more actual length.
