It’s part of a supplementary angle. 180-133 = 47.
Answer:
x = 47°
Step-by-step explanation:
Since CPD is a straight line, then
133 and x are adjacent angles and supplementary, sum to 180° , then
x + 133° = 180° ( subtract 133° from both sides )
x = 47°

Your brother is 13 your age. Your sister is 4 years older than your brother. Your sister is 9 years old. Write and solve an equation to find your age a.
An equation is
???=9.
You are
??? years old.
Answers
answer:
if you rounded it the answer is 15 years old!
step-by-step explanation:
when know that your sister is 9 years old, so lets start off with that. because your sister is 4 older then your brother then that must mean that you brother is 5 years old
9-4
= 5
we also know that you brother is 1/3 your age so divide 5 by 1/3 or .33
5/ .33
= 15.15
but since it looks like we only need the whole number. just round down to 15 since your age is not close enough to round up to 16

To find the perimeter with only one given measurement and the total perimeter, first you need to double the given value. In this case it is 6 so 6 x 2 = 12. After that you need to find the rest of the sides so you can do 30 - 12 = x, or 12 + x = 30. As a total the answer is 18. Finally you divide 18 by two because there is two sides and you get 9.

Answers
Answer:
Luke will earn $ 418.50.
Step-by-step explanation:
Given that on weekends Luke gets paid $ 64.50 per hour, plus a flat rate service fee of $ 75 for every job, and on this Saturday he has three separate jobs that will take 1 1/2, 1/4, and 1 1/4 hours to complete respectively, to determine the money you will earn on the day the following calculations must be made:
(75 x 3) + (1.5 x 64.5) + (0.25 x 64.5) + (1.25 x 64.5) = X
225 + 96.75 + 16.125 + 80.625 = X
418.50 = X
So, all Saturday, Luke will earn $ 418.50.

Factory B produced more tires than factory A because factory B has a median of 112 and factory A has a median of 102
B
Factory B has less variability in production because the range for factory B is smaller than the range for factory A.
с
Factory A has less variability in production because the range for factory A is greater than the range for factory B.

Answer: positive, linear association
Step-by-step explanation: that is the answer, because the dots are rising up in a slope
Answer:
The answer is simple: Positive, linear association. Why is that? It is moving from left to right, increasing as it goes. That is a sign of a positive slope. And, this has a linear association because the points are jumbled together in a clear direction, so we know that we can place a line of best fit.
