Answer:
The length (which is the bottom and top lines) are both 9 inches long.
Step-by-step explanation:
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.

Question 3
The CEO of Hot Tires compares factory production for his two factories using the data in the table shown below.
Factory A Factory B
Production Production
Monday 102
112
Tuesday 106
119
Wednesday 114
105
Thursday 98
96
Friday
101
113
Which inference is valid?
A
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.
D
Factory B produced more tires than factory A because factory Bhas a mean of 109 and factory A has a mean of 104.2.
Find the volume of each figure. Round your answers to the nearest hundredth, if necessary
Answer:
666.67π .ft^3
here's your solution
=> radius of cone = 10 ft
=> height of cone = 20 ft
=> volume of cone = πr^2h/3
=> putting the value of radius and height
=> volume = 10^2*20/3π
=> volume = 666.67π .ft^3
hope it helps
Use the area of the rectangle to find the area of the triangle,
6.ft
7 ft
A. The area of the triangle is 42 square feet, because the area of the
rectangle is 42 square feet
B. The area of the triangle is 21 square feet, because the area of the
rectangle is 21 square feet.
C. The area of the triangle is 21 square feet, because the area of the
rectangle is 42 square feet.
D. The area of the triangle is 26 square feet, because the area of the
rectangle is 24 square feet
Answer:
The correct answer is C:
The area of the triangle is 21 square feet, because the area of the
rectangle is 42 square feet.

Answer:
p+33+p-19+2p-46=180
Step-by-step explanation:
Add all your variables and all your numbers and then simplify
Answer:
p=53
Step-by-step explanation:
(p-19)+(p+33)+(2p-46)=180
53-19=34
53+33=86
2(53)-46=60
34+86+60=180

Luke is a locksmith. On weekends he gets paid \$ 64 . 50 per hour, plus a flat rate service fee of \$ 75 for every job. On this Saturday he has three separate jobs that will take 1 1/2, 1/4, and 1 1/4 hours to complete respectively
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.

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.
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
( here is a tip i have gotten for rounding )

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.

x = (blank) degrees and adding letters so i can ask the question
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°

Dorcas walks a distance of 18 km from home to school at a speed of 6km/h how long does she take to arrive at school?
Time = distance / speed
Time = 18 km / 6 know
Time = 3 hours
Answer:
[tex] \bf \huge 3 \: hours[/tex]
Step-by-step explanation:
Given that :Dorcas walks a distance of 18 km from home to school at a speed of 6km/h.to find :how long does she take to arrive at school ?formulas used :time = distance / speedlet us assume :time = texplanation :⟼ distance = 18 km
⟼ speed = 6 km/h
⟼ t = distance / speed
⟼ t = 18/6 h
⟼ t = 3h
⟼ time = 3 hours.
∴ dorkas take 3 hours. to arrive at school.
