Answer:
n = 1
Step-by-step explanation:
This equation is just basic alegebra. First, combine like terms to get
9 - n = 8n. (Because 3 - 3 = 0, and -4n + 3n = -n.) Now the equation is much simpiler; add n to both sides to get 9 = 9n. Divide 9 by both sides to get that n = 1.
You can check your answer by plugging 1 in for n.
9 - 4(1) + 3(1) = 8(1) + 3 - 3
9 - 4 + 3 = 8 + 3 - 3
5 + 3 = 11 - 3
8 = 8
Therefore, n is proven to equal 1.

a standard toilet uses 1.6 gallons per flush. If a toilet is flushed four times per day, how much water will be used in a month(30days)?
Answer:
192 gallons
Step-by-step explanation:
1.6 gallons x by 4 (the amount of times flushed in a day) = 6.4 gallons a day
6.4x30 (days in a month) = 192
192 gallons of water is being flushed a month
Answer:
192 gallons

Heather finished the 12-kilometer race in 2 hours. If Heather kept her pace constant, what was her rate? A. 24 km/hr. B. 14 km/hr. C. 10 km/hr. D. 6 km/hr.
Answer: D, 6km/hr.
Step-by-step explanation:
Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.
How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.
12 ÷ 2 = 6.
Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.

Find the geometric mean of the pair of numbers 14 and 21.
Type answer as a radical in simplest form.
Solve the equation for x.
x2 = 36
The solutions to the equation are
and
x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6

Answer:
x = -6 or +6
Step-by-step explanation:
You know from your multiplication tables that 6×6 = 36, so one answer is ...
x = 6
You also know that the product of two negative numbers is positive, so another answer is ...
x = -6
__
Check
x² = 6² = 6×6 = 36
x² = (-6)² = (-6)×(-6) = 36
_____
Alternate approach
If you like, you can rewrite the equation as ...
x² -36 = 0
This can be factored to ...
(x -6)(x +6) = 0
The zero product rule tells you this product will only be zero if one or the other factors is zero.
x -6 = 0 ⇒ x = 6
x +6 = 0 ⇒ x = -6
The two solutions are x = ±6.

What is most often given a value of zero to describe an object’s position on a straight line?
displacement
reference point
distance
ending location
Answer:
Reference Point
Step-by-step explanation:
The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.
Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.

A block of ice is in the shape of a rectangular prism. The ice block has a volume of 9,600 cubic inches. After being in a warm area, the size of the block is now 18 inches by 12 inches by 20 inches.
What is the difference between the volume of the ice block before and after it melted?
Answer:
5280 cubic inches
Step-by-step explanation:
V= l * w * h
V= 18 * 12 * 20
V= 4320 cubic inches
Then do the first measurement subtracted by the second one because it wants to know the difference.
9600 - 4320 = 5280 cubic inches

Which of the following graphs could represent the volume of water in a cylinder as a
function of its height? Explain your reasoning.
Answer:
It is A
Step-by-step explanation:
It starts from origin
The first graph represent the volume of water in a cylinder as a
function of its height.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The first graph with a straight line passing through the origin could represent the volume of water in a cylinder as a function of its height.
This is because the formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.
If we keep the radius constant and vary the height, we can see that the volume of the cylinder increases linearly with the height. In other words, the volume is directly proportional to the height.
Since the line passes through the origin, this indicates that when the height is zero, the volume is also zero.
This is consistent with the fact that a cylinder with zero height has zero volume.
Hence, the first graph represent the volume of water in a cylinder as a
function of its height.

Answer: 18 units long
Step-by-step explanation:
In the diagram, it looks like line segment AW is 6 units long and WB is 12 units long. Because of parts-whole postulate (the whole is equal to the sum of its parts), you can add AW and WB's lengths together. 6 + 12 = 18, so the length of line segment AB is 18 units long.

Answer:
76 feet (Just put 76 in the answer box)
Step-by-step explanation:
Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.
2(3.5) + 2(4.5)
The two products would be 7 and 9 respectively.
7 + 9 = 16 feet of fencing for 1 rabbit pen.
We have 2 pens, so multiply 16 by 2.
The rabbit pens need 32 feet of fencing.
(Alternatively you could have done 2(2(3.5 + 4.5)).
2(2(8))
2(16)
32 ft of fencing (rabbit pens))
Now, add 12 and 10. Then multiply that by 2.
2(12 + 10)
2(22)
The garden needs 44 feet of fencing.
Now add 32 and 44 to get the total amount of fencing needed.
32 + 44
The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)
