In polar coordinates, r ² = x ² + y ², so
x ² + y ² = 144 → r ² = 144
12² = 144, so this reduces to
r = 12
which represents a circle with radius 12.

I need the answer to “3x+2y=r solve for x”
Answer:
[tex]x = \frac{r - 2y}{3}[/tex]
Step-by-step explanation:
3x + 2y = r
-2y -2y
3x = r - 2y
Now that 2y has been subtracted from both sides you can isolate the variable. To do that you would divide both sides by 3.
[tex]x = \frac{r - 2y}{3}[/tex]

A fish tank measures 10 inches long and 5 inches wide. Micheal wants to buy a fish tank that can hold 150 cubic inches of water. What is the independent and dependent variable
Answer:
h = 3 inches
Step-by-step explanation:
Volume of the fish tank = length × width × height
Volume = 150 cubic inches
Length = 10 inches
Width = 5 inches
Height = x
Volume of the fish tank = length × width × height
height = volume of the fish tank / length*width
h= 150 / 10*5
h = 150 / 50
= 3
h = 3 inches
The height = 3 inches
From the height formula,
height = volume of the fish tank / length*width
The dependent variable is height
The independent variable are length, width and volume
Which percent is equivalent to 1/2?
O 1%
o 2%
o 25%
o 50%
Answer:
it is 50%
Step-by-step explanation:
1/2 resembles a half of something, 50 is a half of a hundred, 100 would always be the whole or 1000 or 10, the point is that the whole number would always have 1 at the front, and 1 or more zero's at the back, like if someone for example would say, "how good does this taste from a one to a ten" the half would be 5, it's not like someone would say "how good does this taste from a one to a 7, that doesn't make sense, sure it could be a(n) 1000 this time, but you would still do 500 cause it is the half of that.
a shop sells flower fertiliser in 25kg bags and in 50kg bags. one week,the shop has two special offers for the fertiliser.
offer a(25kg) 2 bags for £35 offer b(50kg) 3 bags for £92.50
which offer(a or b ) is the best value for money?
Answer:
Offer b is the best value for money
Step-by-step explanation:
Average Value
To compare different offers of the same product, we often calculate the average value of each offer. Once we have all the values referred to a common base, we can compare and decide.
The shop is offering 2 bags of 25 Kg of fertilizer for £35 and 3 bags of 50 Kf of fertilizer for £92.50.
Since the number of kilograms per bag and the number of bags for each offer are not the same, we calculate the cost of each kilogram of fertilizer for each offer.
The first offer is for 2 bags of 25 kg, that is, 50 Kg of fertilizer. The cost of each kilogram is
£35/50 = £0.7
The second offer is for 3 bags of 50 Kg, that is, 150 Kg of fertilizer, which cost per kilogram is:
£92.50/150 = £0.62
Since the second cost per kilogram is less than the first one, offer b is the best value for money
Which fractions have a decimal equivalent to a repeating decimal
Answer: 19/3
Step-by-step explanation:
If you want to find which have a decimal equivalent to a repeating decimal, all you have to do is divide each one and see which turns out to be a repeating decimal. 19 divided by 3 is 6.333333333 repeating, so it would be a repeating decimal. This is easiest to do with a calculator, but it is also important to learn how to do it by hand.

what's the total area of each smaller space is 5 feet on each side
Answer:
100
Step-by-step explanation:
100
The total area of the four squares is the sum of each individual area of each square. Hence, the total area of the square is 100 ft²
Given that :
Side length of each square, s = 5 feets Area of a square = s²The area of each square can be calculated thus :
Area = 5² = 25 ft²The area of the entire square :
(5² + 5² + 5² + 5²)
(25 + 25 + 25 + 25) = 100 ft²
The total area of the square is 100 ft²
