Writing Prompt Algebra I
Your aunt is planning on building a rectangular pool that measures 10 feet by 12 feet. A
concrete walk around all four sides of the pool will also be included in the deal. However,
your aunt is not sure how big to make the width of the walk. Therefore, the width will be
“x” feet long. Your aunt is wondering how much land will be needed for the pool and the
walkway bordering the pool. You are to write a written description to your aunt telling her
how you would find the area of land needed for the pool and the walkway bordering all four
sides.
Answer: The width is 12 feet, since the pool measures 10 by 12.
Step-by-step explanation:
Your aunt will need 120 square feet of land. I know this because you multiply the length by the width, it equals 120. Then I have to look for the perimeter, and I do this by adding the length twice and add the width twice. This would equal 42.

The cost, C. of producing coolers, x, is modeled by the equation C = 0.005x2 - 0.3x + 17. How many coolers are
produced when the cost is $19. Round your answers to the nearest whole number
All work must be clearly shown, step by step, to receive full credit. Separate your work. Each new statement or
equation, must be on a new line.
Answer:
66 coolers
Step-by-step explanation:
C = 0.005x² - 0.3x + 17
When C = $19
19 = 0.005x² - 0.3x + 17
19 - 17 = 0.005x² - 0.3x
2 = 0.005x² - 0.3x
0.005x² - 0.3x - 2 = 0
x = -b ± √b² - 4ac / 2a
= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005
= 0.3 ± √ 0.09 - (-0.04) / 0.01
= 0.3 ± √ 0.09 + 0.04 / 0.01
= 0.3 ± √ 0.13 / 0.01
= 0.3/0.01 ± √0.13/0.01
= 30 ± 0.36/0.01
x = 30 ± 36
x = 30 + 36 or 30 - 36
x = 66 or -6
Number of coolers can not be negative
Therefore, number of coolers produced when the cost is $19
is 66 coolers

The area of a circle is 36π in². What is the circumference, in inches? Express your answer in terms of \piπ.
Answer:
[tex]12\pi in[/tex]
Step-by-step explanation:
We are given that
Area of circle=[tex]36\pi in^2[/tex]
We have to find the circumference of circle in inches.
We know that
Area of circle=[tex]\pi r^2[/tex]
Using the formula
[tex]36\pi=\pi r^2[/tex]
[tex]r^2=36[/tex]
[tex]r=\sqrt{36}=6[/tex] in
Circumference of circle=[tex]2\pi r[/tex]
Using the formula
Circumference of circle=[tex]2\pi (6)=12\pi in[/tex]
Hence, the circumference of circle=[tex]12\pi in[/tex]
What is the value of z?
=
Answer:
[tex]z=133/6[/tex]
Step-by-step explanation:
All angles in a triangle added up are equal to 180 degrees.
We can make the equation:
[tex]2z+4z+47=180\\6z+47=180\\6z=133\\z=133/6[/tex]
Answer:
Step-by-step explanation:
We have 3 angles, 2z, 4z, 42
the sum of these angles equal to 180
2z+4z+42=180
6z=180-42
6z=138
z=138/6=23
z=23

Answer:
B (-2, 4)
C (-1, 0)
Step-by-step explanation:
(x,y) -> (x - 8, y - 2)
A (2, 3) -> (2 - 8, 3 - 2) = A (-6, 1)
B (6, 6) -> (6 - 8, 6 - 2) = B (-2, 4)
C (7, 2) -> (7 - 8, 2 - 2) = C (-1, 0)

Delilah deposits 8,255 in an account that pays 4.2% simple interest. How much money will be in her account after 8 years
Answer:
11235.35
Step-by-step explanation:
Given data
P=8225
R=4.2%=0.042
T=8years
The simple interest formula is
A=P(1+rt)
Substitute
A=8225(1+0.042*8)
A=8225(1+0.336)
A=8225*1.366
A=11235.35
Hence the balance will be 11235.35
What is the simplified expression of (2x -8) + (3x-2)
Answer:
5x-10
Step-by-step explanation:
Answer:
5x-10
Step-by-step explanation:
You can add the x together, 2+3 is 5 so we have 5x.
The you add the other numbers, -8+-2 is -10.
You then can put the addition in, and have 5x+-10. Since 10 is a negative, there's no need to put the addition sign, so 5x-10 would be the answer.

Answers:
Person A receives at least 800 dollars, but no more than 1600 dollarsPerson B receives at least 1000 dollars, but no more than 2000 dollars=============================================================
Explanation:
We don't have enough information to nail down exact figures, but we can make a range estimate.
The two people (call them A and B) share the profits in the ratio of 4 to 5
In shorthand notation, we can say the ratio is 4:5
This means person A gets 4x dollars while person B gets 5x dollars
The ratio 4x : 5x reduces to 4:5 after dividing both parts by x. The variable x is some positive real number.
The total profit is therefore 4x+5x = 9x dollars
This expression 9x is between 1800 and 3600 dollars, including both endpoints
We then can say...
[tex]1800 \le 9x \le 3600\\\\\frac{1800}{9} \le \frac{9x}{9} \le \frac{3600}{9}\\\\200 \le x \le 400[/tex]
We see that x = 200 is the smallest possible x value. This leads to person A and B receiving 4x = 4*200 = 800 dollars and 5x = 5*200 = 1000 dollars respectively. Note how the ratio 800:1000 reduces to 4:5 after we divide both parts by 200. We can see that 800+1000 = 1800 which is the lowest profit possible.
The inequality above shows that x = 400 is the largest x value possible. If this is the case, then person A receives 4x = 4*400 = 1600 dollars while person B receives 5x = 5*400 = 2000 dollars. The ratio 1600:2000 reduces to 4:5 after we divide both parts by 400. We can see that 1600+2000 = 3600 is the largest profit possible.
-------------------------
To summarize:
Person A can receive anywhere between 800 dollars and 1600 dollars (inclusive of both endpoints).Person B can receive anywhere between 1000 dollars and 2000 dollars (inclusive of both endpoints).The actual amount they receive will depend on what the actual profit is. Since we're only given the range of the profit, we can only make an estimated guess of the range for each partner.
-------------------------
Side note: For either person, the ratio of the max to min is 2:1. This tells us that the max amount they receive is double compared to the min amount they receive. It's no coincidence that 3600 is double that of 1800.
A car drives 160 km in 2 hours.
What is the average speed of the car?
Answer:
The car travelled an average speed of 80 km/h.
Step-by-step explanation:
Distance travelled by the car = 160 km
Time taken by the car = 2 hours.
Average speed =?
Average speed = Distance/Time
Average speed = 160/2
Average speed = 80 km/h
The car travelled an average speed of 80 km/h.
