Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x-5y= -30
Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.
[tex]3x-5y=-30[/tex]
Move the -3x to the right side
[tex]-5y=-3x-30[/tex]
Divide both sides by -5
[tex]y=\dfrac{3}{5}x+6[/tex]

A corporation is under orders to reduce the time office workers spend filling out their TPS reports. Previously the average time spent on the TPS report was 6.3 hours. In order to test whether the time to fill out the TPS report has been reduced, a sample of 48 office workers was randomly chosen, and their completion times recorded. The mean completion time for their TPS reports was 5.7 hours with a standard deviation of 1.8 hours. In order to test that the time to complete the TPS report has been reduced, state the appropriate null and alternative hypotheses.
Answer:
The null hypothesis, H₀ is that the mean completion time for the TPS report remains at the duration of 6.3 hours
The alternative hypothesis, H₁ is that the mean completion time for the TPS report is less than 6.3 hours
Step-by-step explanation:
The given parameters are;
The average time spent on the TPS report = 6.3 hours
The number of workers in the sample used for the test = 48 office workers
The mean completion time of the TPS report for the sample = 5.7 hours
The test aim; To find out whether the mean time required to fill out the TPS report has been reduced
The null hypothesis, is H₀; μ = 6.3 hours
The alternative hypothesis, H₁; μ < 6.3 hours

State of the given binomial is a factor of the given polynomial
Answer:
B no
Step-by-step explanation:
If (n - 10) is a factor then if the polynomial equals zero when evaluated for 10 it is a factor
10³ - 17(10)² + 61(10) + 92
= 1000 - 1700 + 610 + 92
= 2 ≠ 0
Then ( n - 10) is not a factor of the polynomial
A cone has volume 817. What is the volume
of a cylinder with the same radius and height?
Answer:
The volume is 416
Brainly me or heart if this helped
Answer:
volume of cylinder =π r^2 h
Step-by-step explanation:
Volume is proportional to square of radius and linearly proportional to height of cylinder. if h kept constant radius is doubled volume increases by 2^2 ie it becomes 4 fold. If radius trebled volume will be 9 times the original keeping h constant
if you keep h constant increase radius 4 times volume increases by 4 times only
v/πr^2h is constant =π like circumference/diameter =π

Kayla works at a coffee shop. Yesterday she earned $6.25 an hour plus $8.75 in tips. Let x represent the number of hours worked and y represent the total amount earned. Fill in each blank. NO CAPS NO SPACES Slope: Initial value: Equation: y=
Answer:
y = 6.25x + 8.75
Step-by-step explanation:
Kayla works at a coffee shop. Yesterday she earned $6.25 an hour plus $8.75 in tips.
Let x represent the number of hours worked and y represent the total amount earned.
We have,
Net tip = $8.75
She earned $6.25 per hour.
Initial value = 8.75
So,
Total amount earned, y = 6.25x + 8.75
Hence, this is the required solution.

A box of facial tissue has a volume of 180 cubic inches. What is the width of the box if the height was 4 inches, and the length was 9 inches?
Answer:
The width of the box is 5 in
Step-by-step explanation:
the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H. Here we know V, L and H and want to find W. Solving this equation for W, we get W = V/(LH).
With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be
180 in^3
W = ------------------ = 5 in
(4 in)(9 in)
The width of the box is 5 in
Answer:
Solution :-We have
[tex] \begin{cases} \sf Volume = \frak{480 \: cu \: cm}\\ \sf Length = \frak{4 \: in} \\ \sf Height = \frak{4 \: in}\end{cases}[/tex]
Volume = lbh
180 = 9 × b × 4
180 = 36b
180/36 = b
5 = b
Therefore,
Breadth is 5 inMichael has a new job and earns a salary of $27,000. Jackie has a new job and earns a salary
of $36,000. Michael will receive a salary increase of $3,200 per year, and Jackie will receive a
salary increase of $2,100 per year
Which equation can be used to find x, the number of years it will take Michael to earn the same
salary as Jackie?
A. 27,000x + 3,200x = 36,000x + 2,100x
B. 27,000x + 3,200 = 36,000x + 2,100
C. 27,000x + 3,200x = 36,000x + 2,100
D. 27,000 + 3,200x = 36,000+ 2,100x

Wolverine is three years older than Storm Cyclops is two years younger than Storm. The
sum of their age is 106. How old are each of them
Answer:
Storm is 35, Cyclops is 33 and Wolverine is 38.
Step-by-step explanation:
W, S and C represent the agres of Wolverine, Storm and Cyclops.
W = S + 3
C = S - 2
W + S + C = 106
Making the indicated substitutions, we get:
(S + 3) + S + (S - 2) = 106
Combining like terms:
3S + 1 = 106, and 3S = 105. Thus,
S = 35, C = 35 - 2, and W = S + 3.
Storm is 35, Cyclops is 33 and Wolverine is 38.

We have to find out which is the longest from them.
What is the meaning of unit conversion ?
A unit conversion is done to express the same property as a different unit of measurement.
As per the question ;
Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.
Let's check which is the longest by converting them all in same units say centimeters.
So ;
a) 90 centimeters
= 90 centimeters
b) 40 meters
= 40 × 100 centimeters
= 4000 centimeters
c) 30 kilometers
= 30 × 1000 meters
= 30000 × 100 centimeters
= 3000000 centimeters
d) 10 meters
= 10 × 100
= 1000 centimeters
e) 40 millimeters
= 40 / 10 centimeters
= 4 centimeters
So ; the longest is 30 kilometers.
Thus , the longest measure from the given measures is 30 kilometers.

what is the measure of angle 5?
Answer:
70
Step-by-step explanation:
add 90 to 130 which equals 220 then subtract 220 from 360 which gives you 140 and after divide 140 by 2 and you get 70
130+90=220
360-220=140

The surface area of a certain pyramid is 54 square meters.
Its volume is 648 cubic meters. If a similar pyramid has a
volume of 8232 cubic meters, what is its surface area?
Answer:
294 square meters
Step-by-step explanation:
The surface area of a certain pyramid is 54 square meters. Its volume is 648 cubic meters. If a similar pyramid has a volume of 8232 cubic meters, what is its surface area?
We solve the above question using Proportion
The surface area of a certain pyramid
= 54 square meters.
Volume of certain pyramid =
648 cubic meters.
Surface area of similar pyramid = x
Volume of similar pyramid = 8232 cubic meters.
Hence,
Surface area : Volume
= Surface area/ Volume
= 54 m²/648 m³ = x/8232 m³
Cross Multiply
54 × 8232 = 648 × x
x = 54 × 8232/648
x = 294 square meters
