What’s the value of a?
Answer:
a = 69
Step-by-step explanation:
The linear pair equals 180 degrees.
a + 90 + 21 = 180
a + 111 = 180
a = 69
nice!
Answer:
A= 69 degrees
Step-by-step explanation:
if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.
21 + 90 = 111
180- 111 = 69
Jackson’s car was making a rumbling noise for two weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat fee of $60 and $35 for each hour he spends trying to identify the problem.
A. Write a linear equation in y = mx+b form to represent the cost of getting Jackson’s car diagnosed.
B. Identify the slope and y-intercept, and what they mean in the context of the story.
C. Does this situation represent a proportional relationship? Why or why not?
Answer:
y=35x+60
slope-35 y intercept-60
proportional relationship
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 35x + 60
Slobe 35
y-intercept 60
The y-intercept is the start cost and the slope is how much it will go up per hour.
It is proportional because it is going up by 35 every hour

Find the surface area of the above solid.
For each sequence, find the first 4 terms and the 10th term.
a) 3n + 4
b) 4n-5
Answer:
see explanation
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the formula, that is
(a)
a₁ = 3(1) + 4 = 3 + 4 = 7
a₂ = 3(2) + 4 = 6 + 4 = 10
a₃ = 3(3) + 4 = 9 + 4 = 13
a₄ = 3(4) + 4 = 12 + 4 = 16
Similarly substitute n = 10 for tenth term
a₁₀ = 3(10) + 4 = 30 + 4 = 34
(b)
a₁ = 4(1) - 5 = 4 - 5 = - 1
a₂ = 4(2) - 5 = 8 - 5 = 3
a₃ = 4(3) - 5 = 12 - 5 = 7
a₄ = 4(4) - 5 = 16 - 5 = 11, and
a₁₀ = 4(10) - 5 = 40 - 5 = 35

Which table represents a linear function?
× + 2 + 2x + 3 = 4x PLS HELP ME
Answer: 8
Step-by-step explanation:
Answer:
I dont know what your supposed to do but i can tell you that x = 5 because if you simplify the equation you get 3x + 5 = 4x. Using this you can infer that a single x is equivalent to 5 since you need 5 to get from 3x to 4x.

A sprinkler system uses 800 gallons of water in 5 days. The system uses ___ gallons of water in 1 day
Answer:
160
Step-by-step explanation:
800 gallons in 5 days. The days is the denominator and the gallons are the numerator, whatever you do the the bottom you do to the top, so you divide the denominator by 5 and the numerator by 5 and you get 160 gallons per day. If you want to know how your answer is right, multiply 160 by 5
-2(7 – n) + 4
What is the answer to this any body know it??????????
Answer:
2n+10
Step-by-step explanation:
you just distribute the -2 and you get -14+2n+4 and then add and you'll get 2n+10
if you are solving for the variable n then you would want your equation like this 2n+10=0
next you would put the 10 on the other side of the equation and have 2n=-10
finally you would divide by 2 and get n=-5
The histogram shows the number of hours volunteers worked one week.

What is the positive solution to the equation 3x2 + 31 = 912
A 10.95
B 8.51
8.36
D 7.75
E 4.47
Answer:
E) 4.47
Step-by-step explanation:
3x²+31=91
3x²=91-31
3x²=60
x²=60÷3
x²=20
x=√20
x=4.47
Answer:
4.47
Step-by-step explanation:
the only rational answer for this is 4.47 because once you solve as much as you can, you should end up with a whole number multiplied by a square root. the decimal form of that number is 4.47
Solve
S = 2πr(h + r) for h
Answer:
S/2πr-r = h
Step-by-step explanation:
S = 2πr(h + r)
S/2πr = h+r
S/2πr - r = h
8. Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept
form, simplifying all fractions.
6x + 15y = -15
Answer:
-2/5-1
Step-by-step explanation:
6x+15y=(-15)
subtract both sides by (-6x)
now the equations becomes: 15y=(-6x)-15
divide both sides by 15, since -6 cannot evenly we just leave it as a fraction
Equation becomes y= -6/15x-1
Then simplify it down to y= -2/5x-1
