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.

Explain how to decompose a triangle into congruent triangles. How do those decomposed pieces relate to the area of the rectangle?

Answers

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

Step-by-step explanation:

First you would have to divide the rectangle into half, to form two congruent triangles. Then if you multiply the area of 1 of the triangles, it will give you the area of both triangles, and so the area of the triangle as a whole.

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.

Answers

Answer:

1. Mean: 103

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.
