In a community survey, 13/20 of the residents claim to recycle. If there are 720 residents, how many residents claim to recycle?
Answer:
468
Step-by-step explanation:
make a proportion:
13/20 = x/720
20x?=720
20x36=720
whatever you do to the bottom you do to the top
13x36=468
468/720 residents claim to recycle

A cylindrical shaped swimming pool has a diameter of 30 feet and a water height of 4.5 feet. How many cubic feet of water is contained in the pool? Use 3.14 for pi. Round your answer to the nearest cubic foot.
Answer: A
Step-by-step explanation:
The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.
Next, the volume of a cylinder is V= πr²h
R is the radius
h is the height
π= 3.14 (in this question).
We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.
R= 15
H= 4.5
Pi= 3.14
Now we can plug into the formula:
Using pemdas, do exponents first. Then multiply from left to right.
V= πr²h
V= 3.14x15²x4.5
V= 3.14x225x4.5
V= 706.5x4.5
V= 3,179.25
3,179.25 rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A
Hope this helps :)) Also brainliest would be appreciated, I worked pretty hard on this :D

Carina is borrowing $27,000 to buy a new car. If she borrows the money at 4.15% interest compounded annually for 5 years, how much interest will she pay on her car loan?
$33,087.21
$6,087.21
$1,120.50
$5,602.50
Answer:
NO, the these three border pieces will not make a right triangle
Step-by-step explanation:
Use the compound amount formula A = P(1 + r)^t:
Here A = ($27,000)(1 + 0.0415)^5
A = ($27,000)(1.0415)^5 = $33,087.21
Subtracting the principal amount, $27,000, leaves the compound interest amount: $33,087.21 - $27,000 = $6087.21
She will pay $6,087.21 interest on this loan.

How do you convert mass to volume without density?
Answer:
Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be
The general formula is:
ρ
=
m
V
where
ρ
is density in
g/mL
if mass
m
is in
g
and volume
V
is in
mL
.
So to get the mass...
m
=
ρ
V
Or to get the volume...
V
=
m
ρ
When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.
Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.
These days, you should be able to search for the density of any common object.
When you have the density and volume but not the mass, then just make up a mass.
You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
Don't guess!

Which key correctly represents the information below?
A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13
Answer:
The correct answer is C) 11 | 2 = 112
Step-by-step explanation:
That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:
112, 112, 115, 118.
The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.
Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)
Can you please help me solve this ?!?!
Answer:
x = -72
Step-by-step explanation:
Using algebra:
⇒ [tex]-\frac{x}{8} -11 = 2[/tex] (First add 11 to both sides of "=")
⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")
⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)
⇒ [tex]x = -72[/tex]
Hope this helped, Good Luck!

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118
