which would give you -18t-3
It C to because 1. expand by distributing terms -(18t+9)+6

gas truck, The truck is 40 feet long and the radius of the base is 60 inches, Gas has a density of five pounds per
cubic foot. Mr. Franklin makes $2.50 per pound of gas when he sends a delivery. How many trips of full tanks of
gas will Mr. Franklin have to send to pay for his three kids to go to four years of college each?
Be sure to label each step and show all work. Don't forget units.
a) Find the volume of the cylinder
b) Find the mass of the gas in one truckload by using the density formula
c) Find the amount of money one truckload will generate.

The answer goes here,
a) We have to tell the time and day which simone has to tell her sister, for picking her up from airport.
b) We have given the day (monday), time(7:00 pm) and total time to reach the destination(18 hours).
c) No such formula will be used here, we will just use our mental ability to solve this question.
d) She will leave at 7:00 pm, day has 24 hours. So, she will be in the flight on monday:
= 24 - (12 + 7) ----------- [12 here means the time of rest of the day,(morning to noon)]
= 24 - 19
= 5 hours
So, she will complete 5 hours of her destination on monday,now the time left is:
= 18 - 5
= 13
= (12 + 1 )hours
So, on tuesday, she will be in the flight for 12 hours (noon) and then on 1:00 pm she will reach the airport, as she needs and extra hour to plane so, the final time is 1:30 pm. And finally, the time she should tell her sister is 1.30 pm.

Work Time Lost due to Accidents At a large company, the Director of Research found that the average work time lost by employees due to accidents was hours per year. She used a random sample of employees. The standard deviation of the sample was hours. Estimate the population mean for the number of hours lost due to accidents for the company, using a confidence interval. Assume the variable is normally distributed. Round intermediate answers to at least three decimal places. Round your final answers to the nearest whole number.
Answers
Answer:
(95.215 ; 100.785)
(95 ; 101) (nearest whole number)
Step-by-step explanation:
To obtain the confidence interval :
Mean ± margin of error
Mean = 98 hours
Margin of Error = Tcritical * (s/√n)
samole standard deviation, s = 5.6 hours
df = n - 1 = 18 - 1 = 17
Tcritical at (0.05, df = 17) = 2.110
Hence ;
Margin of Error = 2.110 * (5.6/√18) = 2.785
Confidence interval :
98 ± 2.785
Lower boundary = 98 - 2.785 = 95.215
Upper boundary = 98 + 2.785 = 100.785
(95.215 ; 100.785)
A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 ft3 / sec sec . Find the rate of change of the radius of the surface of the water when the radius of the surface of the water is 2 2 ft. (You must also include the units)
Answers
Answer:
[tex]\frac{dr}{dt}=0.11062ft/sec[/tex]
Step-by-step explanation:
From the question we are told that:
Radius [tex]r=5ft[/tex]
Height [tex]H=15ft[/tex]
Rate [tex]R=15ft/3sec =5ft/s[/tex]
Surface Radius [tex]R_{surf}=2.2ft[/tex]
Generally the equation for Volume is mathematically given by
[tex]V=\frac{1}{3}\pi*r^2h[/tex]
Since radius to height ratio gives
[tex]\frac{r}{h}=\frac{5}{15}[/tex]
[tex]\frac{r}{h}=\frac{1}{3}[/tex]
[tex]h=3r[/tex]
Therefore
[tex]V=\frac{1}{3}\pi*r^2(3r)[/tex]
[tex]V=\pi r^3[/tex]
Generally the equation for Change of Volume is mathematically given by
[tex]\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)[/tex]
[tex]\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}[/tex]
[tex]\frac{dr}{dt}=\frac{5}{45.62}[/tex]
[tex]\frac{dr}{dt}=0.11062ft/sec[/tex]

Answers
Answer:
Step-by-step explanation:
$39
The net worth should be considered as the $39.
Calculation of the net worth;We know that
Net worth = Total assets - total liabilities
here,
total assets = checking & savings + baseball card + check for work done
= $275 + $210 + $19
= $504
And, the total liabilities = owe + borrowed
= $415 + $50
= $465
So, the net worth be
= $504 - $465

Answers
Given:
The geometric sequence is:
25.5, 5.1, 1.02, 0.204, ...
To find:
The explicit rule for the given geometric sequence.
Solution:
We have,
25.5, 5.1, 1.02, 0.204, ...
Here, the first term is 25.5 and the common ratio is:
[tex]r=\dfrac{a_2}{a_1}[/tex]
[tex]r=\dfrac{5.1}{25.5}[/tex]
[tex]r=\dfrac{1}{5}[/tex]
The explicit rule for a geometric sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
Putting [tex]a=25.5,\ r=\dfrac{1}{5}[/tex] in the above formula, we get
[tex]a_n=25.5(\dfrac{1}{5})^{n-1}[/tex]
Therefore, the correct option is B.

Given :
A function f(x) for different range of x.
To Find :
The value of f( -3 ) .
Solution :
We have to find the value of function at x = -3.
Now, in the given figure -3 lies in range x ≤ -2 and definition of function at that range is :
[tex]f(x) = \dfrac{2}{x}[/tex]
So, putting value of x = -3 in above equation, we get :
[tex]f(-3) = \dfrac{2}{-3} \\\\f(-3) = \dfrac{-2}{3}[/tex]
Hence, this is the required solution.

Helaine graphed the equation 12x−4y=3. What was the slope of Helaine’s line?
Answers
Answer:
The slope is 3
Step-by-step explanation:
12x−4y=3
Solve for y
Subtract 12x from each side
-12x +12x−4y=-12x+3
-4y = 12x+3
Divide each side by -4
-4y/-4 = -12x / -4 +3/-4
y = 3x -3/4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 3
Answer:
The slope is 3
Step-by-step explanation:
12x−4y=3
Solve for y
Subtract 12x from each side
-12x +12x−4y=-12x+3

Divide each side by -4
-4y/-4 = -12x / -4 +3/-4
