Answer:
14,112 mile/year
Step-by-step explanation:
169344÷12 = 14,112 mile/year
To determine the rate that an individual walks. Take each set values and put in the following formula to solve for the rate.
Rate = number of feet/ seconds
Person 1 = 60 feet / 10 seconds = 6 feet/sec
Person 2 = 25 feet / 5 seconds = 5 feet/second
Person 1 walks at a faster rate than person 2.
For the top: 10(4-7), distribute the 10 to both 4 and -7
10(4) = 40
10(-7) = -70
For the bottom, - is the same as - 1
Distribute -1 to both 4 and -1
-1(4) = -4
-1(-1) = 1
(40 - 70)/(-4 + 1)
Simplify. combine the terms.
40 - 70 = -30
-4 + 1 = -3
Divide:
-30/-3 = 10
D. 10 is your answer

Answer:
x = 10.5 in
Step-by-step explanation:
The rectangles are similar, thus the ratios of corresponding sides are equal.
that is = ( cross- multiply )
2x = 21 ( divide both sides by 2 )
x = 10.5
Answer: The answer is 40 degrees
Step-by-step explanation: Angles CDE and ABC are congruent and the sum of the other angles together is 140 degrees. Since all triangles add up to 180 degrees 40 degrees is left.
