A cylinder has a volume of 8,792 cubic units. If the height of the cylinder is 7 units, which of the following represents the radius of the cylinder?
Answer:
I think its 20 units I could be wrong though
Step-by-step explanation:
The radius of the cylinder = 19.99 units
What is the volume of the cylinder?[tex]V=\pi r^{2} h[/tex], where 'r' is the radius and 'h' is the height of the cylinder.
For given example,
the height of the cylinder (h) = 7 units
the volume of the cylinder (V) = 8792 cubic units
Using the formula for the volume of the cylinder,
⇒ V = π × r² × h
⇒ 8792 = π × r² × 7
⇒ r² = 8792/(7 × π)
⇒ r² = 399.8
⇒ r = 19.99 units
Therefore, the radius of the cylinder = 19.99 units

What is the volume in cubic inches of the
pyramid?
HINT: 1. The base is a square, therefore all sides are the same.
2. Multiply all the numbers and then divide by 3 since the formula is V = 1/3 Bh.
Final answer:
The volume of the pyramid can be found using the formula V = (1/3) * B * h, where B is the area of the base and h is the height of the pyramid. Plugging in the given values, the volume is 60 cubic inches.
Explanation:
To find the volume of a square pyramid, you can use the formula V = (1/3) * B * h, where V represents the volume, B represents the area of the base, and h represents the height of the pyramid.
In this case, the base is a square, so the area of the base is side * side. Since the base edge is 6 inches, the area of the base is 6 * 6 = 36 square inches.
Plugging in the values for B and h into the formula, we get V = (1/3) * 36 * 5 = 60 cubic inches.

The teachers created the table shown. Approximately what percent of all students in a foreign language class are 9th graders taking Spanish?
A) 56%
B) 52%
C) 27%
D) 21%
Answer:
27%
Step-by-step explanation:
Add the number of students: 87+86+71+92= 336
Divide the number of 9th grade Spanish students by the total number of students: 92÷336= 0.27
Times by 100 to get a percentage: 27%
Final answer:
To find the percentage of 9th graders taking Spanish compared to all students in foreign language classes, add the counts from all classes to find the total, then divide the number of 9th grade Spanish students by this total and multiply by 100.
Explanation:
To determine the percent of all students in a foreign language class that are 9th graders taking Spanish, we would need the total number of students taking foreign languages and the number of those who are 9th graders taking Spanish. Let's assume we have the following numbers in our data table:
8th grade French students
9th grade French students
8th grade Spanish students
9th grade Spanish students
Add the numbers of all the students together to find the total. Then, divide the number of 9th grade Spanish students by the total and multiply by 100 to get the percentage.
For example, if there are 100 students in total and 27 of them are 9th graders taking Spanish, the calculation would be:
(27 / 100) * 100% = 27%

1/8+c=4/5 plzzzzzz i need help
Answer:
c = 27/40
Step-by-step explanation:
1/8+c=4/5
Subtract 1/8 from each side
1/8 - 1/8+c=4/5-1/8
c = 4/5 - 1/8
The common denominator is 40
4/5 *8/8 =32/40
1/8 *5/5 =5/40
c = 32/40-5/40
=27/40
1/8 + c = 4/5
Multiply by common denominator 40=5(8).
5 + 40c =32
40c = 32-5 = 27
c = 27/40
Answer: c = 27/40
mr. and mrs. Rainer took out a $240,000 loan to purchase their home. If the interest rate on the loan is 1.2% compounded bimonthly, how much interest will they paid after 30 years?
Answer:
$103968.11.
Step-by-step explanation:
Given information:
Principal amount = $240,000
Rate of interest = 1.2% = 0.012
Number of years = 30
Number of times in an year = 24
Formula for amount:
[tex]A=P(1+\dfrac{r}{n})^{nt}[/tex]
where,
P is principal, r is rate of interest, t is number of years, n is number of times interest compounded in a year.
[tex]A=240000(1+\dfrac{0.012}{24})^{24(30)}[/tex]
[tex]A=240000(1.0005)^{720}[/tex]
[tex]A=343968.11[/tex]
Now,
[tex]Interest=A-P[/tex]
[tex]Interest=343968.11-240000[/tex]
[tex]Interest=103968.11[/tex]
Hence, the interest is $103968.11.
Final answer:
The total interest paid on a $240,000 loan with a 1.2% interest rate compounded bimonthly over 30 years is $103,875.4
Explanation:
Calculating Compound Interest Over 30 Years
Mr. and Mrs. Rainer took out a $240,000 loan for their home with an interest rate of 1.2% compounded bimonthly. To calculate the total amount of interest they will pay after 30 years, we need to use the formula for compound interest:
A = [tex]P(1 + \frac{r}{n})^{nt[/tex]
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount ($240,000)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
First, convert the interest rate from a percentage to a decimal by dividing by 100:
r = 1.2% / 100 = 0.012
Since the interest is compounded bimonthly, it is compounded 6 times a year (n = 6). The loan is for 30 years (t = 30).
Now, we can substitute the values into the formula and calculate A:
A = [tex]$240,000(1 + \frac{0.012}{6})^{6*30[/tex]
A = 240,000 * 1.002¹⁸⁰
A = 343,875.4
We'll subtract the principal (P) from A to find the total amount of interest paid over the 30 years.
I = A - P
I = 343,875.4 - 240,000
I = 103,875.4

An angle is formed when two straight lines or rays meet at a common endpoint.
The two angles are said to be adjacent angles when they share the common vertex and side
B is the common vertex.
The vertex of an angle is the common endpoint of two rays that form the angle.
We need to find the adjacent angles of ∠ABC.
∠ABE and <DBC are the adjacent angles of ∠ABC as they having the same vertex B.
They are vertical angles and share the same vertex point B.
The two angles that are adjacent to ∠ABC are ∠ABE and <DBC are
Hence, ∠ABE and <DBC are the two angles that are adjacent to ∠ABC.

What is the probability of getting the same colour twice?
brainliest - asap please!
The probability of getting the same colour twice when a fair spinner with 10 sections (3 red, 4 blue, 3 green) is spun twice is 34%.
Explanation:This question is about the concept of probability in Mathematics. Since the spinner is spun twice and we want the same colour both times, we need to calculate the probability for each colour and then add them together.
There are 10 sections in total on the spinner, with 3 being red, 4 being blue, and 3 being green:
The probability of spinning red twice is (3/10)*(3/10) = 9/100. The probability of spinning blue twice is (4/10)*(4/10) = 16/100. The probability of spinning green twice is (3/10)*(3/10) = 9/100.
So the total probability of getting the same colour twice is 9/100 + 16/100 + 9/100 = 34/100 = 0.34 or 34%.

to find x you plug the two equations equal to each other and solve for x
3x + 50 = 6x - 10
subtract 3x by both sides --> 50 = 3x - 10
add 10 to boths sides --> 60 = 3x

What polygon has 4 equal sides, 2 obtuse angles and 2 acute angles?
A.square
B.rectangle
C.trapezoid
D.fhombus
Answer:
If you meant to type rhombus, instead of fhombus than d is your answer.
Step-by-step explanation:
It is not square because a square has 4 right angles. It isn't rectangle because there isn't 4 equal sides, and isn't trapezoid because there isn't four equal sides either.
Final answer:
A polygon with 4 equal sides, 2 obtuse angles, and 2 acute angles is known as a rhombus, since squares and rectangles only have right angles, and trapezoids typically do not have 4 equal sides.
Explanation:
The polygon in question has 4 equal sides, 2 obtuse angles, and 2 acute angles. This description rules out a square (option A) and a rectangle (option B) since they only have right angles, and it rules out a trapezoid (option C) since a trapezoid typically does not have 4 equal sides. The remaining option is a rhombus (option D), which fits the given criteria. In a rhombus, all sides are indeed equal, and it can have 2 obtuse and 2 acute angles.
It's important to know that the sum of the interior angles in any quadrilateral is 360°, which holds true for a rhombus as well. In addition, understanding that angles on a straight line equal 180° can be helpful when analyzing the properties of quadrilaterals.
