Answer:
First Question's Answer = 7 + A
Second Question's Answer = (2 x 5) x 7
Step-by-step explanation:
The commutative property of addition states that numbers can be added together in any order without changing the resulting sum.
Therefore, A + 7 = 7 + A
The associative property of multiplication states the way in which three or more terms are grouped does not change the product.
therefore, 2 x (5 x 7) = (2 x 5) x 7

You get out of school and walk north for 20 minutes. You
travel 1. 6 km. What is your average velocity?
1
Answers
Answer:
Step-by-step explanation:
Velocity is change in displacement over change in time.
v = d/t
In this problem, d = 1.6 km and t = 20 minutes
To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.
You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.

There are 30 businesses with 4 executives each for the new office building. Each business needs one office for each of its
executives. The building has 1,440 offices. What is the proportion of executives to offices?
A 1 to 12
B
4 to 1
C
1 to 6
D
6 to 1
Answers
Answer:
A. 1 to 12
Step-by-step explanation:
if each business has 4 executives there is a total of 120 executives
30(4) = 120
to find the proportion of executives to offices we divide the number of offices by the number of executives
1440/120 = 12
a more in depth look is
1440 offices / 120 executives
"offices" and "executives" cannot divide each other out, but the 1440 and 120 can so it would be
12 offices / 1 executive

An engineer needs to create a bridge that consists of right triangles for support. Determine whether the triangle shown is a right triangle.
Be sure to include your answer and show/explain the steps you used to solve.
Answers
Answer:
See below
Step-by-step explanation:
We can see that the thick line which outlines the main cable, the base and tower form a triangle
The longest length is the main cable which is 15m
If it is indeed a right triangle. the squares of the sums of the two shorter sides must equal the square of the longer side.
Sum of squares of shorter sides(also called legs) = 9² + 12²
= 81 + 144
= 225
Square of the longer side = 15² = 225
Since 15² = 9² + 12²
the triangle shown is indeed a right triangle with hypotenuse = 15m and the legs of the right triangle 9m and 12m

Answers
Answer:
258 ft
Step-by-step explanation:
seperate the polygon into two boxes that way u have one big box that is 21 ft in width and 8 ft in height. Then multiply 21*8 to find the area of the box which is 168.
for the other box you can find the height by subtracting 18 ft and 8 ft from the first box which gives a height of 10 ft. To find the wisth you have to subtract 21-12 which is 9. Now you can multiply 10*9=90
Add the two boxes together:
90+168=258

Answers
Answer: 0.12, 1/8, 14%, 0.2
Step-by-step explanation:
We can try and convert everything to a decimal in order to make things easier. 0.12 and 0.2 are already given to us. Now we convert 1/8 to a decimal by dividing 1 by 8 and you should get 0.125. Next convert 14% to a decimal by moving the decimal place 2 places foward, which gives you 0.14. Your numbers are 0.12, 0.2, 0.125, and 0.14 now you place them into order from least to greatest. Since one of them is three digits you can make the rest three digits to make it easier. 0.120, 0.200, 0.125, 0.140.
Your final answer would be 0.12, 0.125, 0.14, 0.2
