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

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

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 :)

Walden gives the pizza delivery person an $8.00 tip, which was 12% of the cost of his pizzas. How much was the total amount that Walden spent? Round your answer to the nearest cent.
ANSWERS WITH WEIRD FILE THINGYS WILL BE REPORTED IMMEDIATLY
Answer:
$17
Step-by-step explanation:
Tip = $8.00
Pizzas cost:
First you have to do 12% of $8.00 which = $0.96
Then you have to add the $0.96 to the $8.00 which = $8.96
Total = $8.00 + $8.96
= $16.96
then round it to nearest cent which is $17
Answer:
$74.67
Step-by-step explanation:
$8 was 12% of the cost of the pizzas, so we have to add that to the initial cost. The initial cost can be found by (8*100)/12, which would be $66.67. Since we need to find the total amount of money spent, we have to add the initial cost of pizzas and the $8 tip, which is 12% of that. Final answer is $74.67

I'm confused I put 13-x and it said incorrect?? HELP!
Answer:
Maybe -12?
Step-by-step explanation:
Because sometimes variables on their own symbolize 1, so we can subtract 13 from 1 to get -12.

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!

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.
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
The sequence 10, 15, 22.5, 33.75, ... represents the percentage of votes a particular political candidate has according to polls each day after they participated in a charity event. Does the sequence have a common ratio or a common difference? Is it a geometric sequence?
Answer:
it is a geometric sequence
Step-by-step explanation:
the common ratio is 1.5.
you have to divide 15/10 and that will give you 1.5
then 22.5/15. the answer is 1.5

Find the value of x and find whether the angles or supplementary or complementary.
Answer:
1) x = 31
2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).
Step-by-step explanation:
1) Since both angles add up to be a supplementary,
→ equation 1 + equation 2 = 180
→ (3x + 25) + (2x) = 180
Solving by applying algebra will give the answer "x = 31".
Hope this helps!
