New cylinder:
h = 15cm
V= 1130.4 cm³
πr²h = 1130.4
3.14*r²*15=1130.4
r²=1130.4/15*3.14
r²=24
r=√24
r=4.898 = 4.9 cm
The radius be to meet the client's need is 4.9 cm.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.
Volume is sometimes referred to as capacity.
We have,
Radius of cylinder (r)= 6 cm
Height of cylinder (h) = 10 cm
and, Height of new cylinder (H) = 15 cm
Radius of new cylinder = R cm
Now, Volume of cylinder can be compared as
πr²h = πR²H
6 x 6 x 10 = R² x 15
360 / 15 = R²
R² = 24
R= 4.9 cm
Thys, the radius is 4.9 cm.

angle K and angle L are complementary angels. If the measurement of angle K =(3x+3) and the measurement of angle L =(10x-4).what is the measure of each angle
The measurement of two angles is 24° and 66°
Step-by-step explanation:
First of all, let us define complementary angles
The angles whose sum is 90° are called complementary angles
Given
∠K = (3x+3)
∠L = (10x-4)
According to the definition,
[tex]K+L = 90\\3x+3 + 10x-4 = 90\\13x -1 = 90\\13x-1+1 = 90+1\\13x = 91[/tex]
Dividing both sides by 13
[tex]\frac{13x}{13} = \frac{91}{13}\\x = 7[/tex]
So,
∠K = 3x + 3 = 3(7) + 3 = 21+3 = 24°
∠L = 10x - 4 = 10(7) -4 =70 -4 = 66°
Hence,
The measurement of two angles is 24° and 66°

Which ordered pair is a solution to the system of linear equations Negative 4 x + y = 8 and x minus 5 y = 17?
Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
The solution of the given system of equations is [tex]y=-4[/tex].

Slope=2; (14,33)
What is the slope
Step-by-step explanation:
Hi! I am a little confused because in this question they would normally ask for the equation of the line but if you are wondering what the slope is, it says in the information that the slope is 2. I will solve for the line equation anyway though.
A line has this form: y=mx+b.
For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.
First, we can put in the point into the equation. The point given is (14,33) so the x value is 14 and they y value is 33.
y=mx+b
33=m(14)+b
We know the slope is 2 (from the given information) so we can substitute that in for m.
33=(2)(14)+b
Solving for b, the Y-intercept, we get b=5.
Perhaps your question was "what is the Y-intercept" and then this would be the answer.
Finally, the final equation for the line is:
y=2x+5

Find the sum of the whole numbers from 1 to 960
Step-by-step explanation:
A quick way to do this sort of question:
First add the last number and the first number:
1 + 960 = 961
Then divide the total amount of numbers by 2.
960 ÷2 = 480
Now multiply these two numbers together:
961 × 480 = 461280
The sum of the whole numbers from 1 to 960 can be found using the formula for the sum of an arithmetic series. By substituting the values into the formula, we find that the sum is 461280.
Explanation:The sum of the whole numbers from 1 to 960 can be found using a simple formula for the sum of an arithmetic series. The formula is S = n/2 * (a + l), where 'n' is the number of terms, 'a' is the first term, and 'l' is the last term.
In this case, 'n' is 960 (there are 960 terms from 1 to 960), 'a' is 1 (the first term), and 'l' is 960 (the last term).
Plug these values into the formula to get: S = 960/2 * (1 + 960) = 480 * 961 = 461280. So, the sum of the whole numbers from 1 to 960 is 461280.

Nia told Patrick that her new backpack only cost $14 because she used a 30% off coupon when she bought it. Patrick wants to buy a similar backpack. How much will it cost if he does not have a 30% coupon?
Please answer quick, and please show steps on how you did it, tysm.
Nia's backpack after 30% off represents 70% of the original backpack cost. Setting up a ratio of 70/100 = 14/X, we can solve for the original price, X. Patrick will pay $20 if he does not have a 30% off coupon.
Explanation:This problem can be solved using a bit of Percentage Calculations. We know that after a 30% discount, Nia's backpack cost $14. This means that $14 represents 70% of the original backpack cost (100% - 30%). So to find out the 100%, or the full price, we need to determine what number 70% is 14 of. We can set up a ratio to find the original cost (X).
The steps are:
We write the equation 70/100 = 14/X where X is the original price.Then we cross-multiply to solve for X: 70 * X = 100 * 14. Which simplifies to X = (100 * 14) / 70Calculate the value to get X = 20.So, the backpack would cost Patrick $20 without a 30% off coupon.

An apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant. The apartment building has 92 total occupants.
2× + 16 =92
How many double-occupancy apartments are currently rented?
The currently rented double-occupancy apartments are 38 apartments.
Step-by-step explanation:
An apartment has rented x apartments with two occupants and 16 apartments with one occupant and the total occupants were 92, these can be written in the equation as
[tex]2x+16=92[/tex]
To find the number of double occupancy apartments that are rented, we need to solve the equation and find the value of x.
[tex]2x+16=92[/tex]
Subtracting 16 from both sides of the equation,
[tex]\begin{aligned}&2 x=92-16\\&2 x=76\end{aligned}[/tex]
Dividing both sides by 2, we get,
[tex]\begin{aligned}\frac{2 x}{2} &=\frac{76}{2} \\x &=38\end{aligned}[/tex]
Thus, there are 38 double-occupancy apartments are currently rented.
The correct answer is that there are 38 double-occupancy apartments currently rented.
To solve the problem, we start with the given equation that represents the total number of occupants in the apartment building:
[tex]\[ 2x + 16 = 92 \][/tex]
This equation takes into account that each double-occupancy apartment (x) houses two occupants, and there are also 16 single-occupancy apartments. We want to find the value of x, which represents the number of double-occupancy apartments.
First, we subtract 16 from both sides of the equation to isolate the term with x:
[tex]\[ 2x + 16 - 16 = 92 - 16 \][/tex]
[tex]\[ 2x = 76 \][/tex]
Next, we divide both sides of the equation by 2 to solve for x:
[tex]\[ \frac{2x}{2} = \frac{76}{2} \][/tex]
[tex]\[ x = 38 \][/tex]
Therefore, there are 38 double-occupancy apartments currently rented in the building. This matches the correct answer provided at the beginning.
What is y = 4 * (0.8) ^ t
The function y = 4 * (0.8)^t is an exponential decay function, representing the decrease of a quantity over time, with y being the value at time t. To find y at any given t, substitute t into the equation and calculate the result.
Explanation:The given function y = 4 * (0.8)^t is an exponential decay function, where y represents the value of the function at time t, the number 4 is the initial value of the function when t = 0, and 0.8 is the decay factor relevant for each time unit. This type of function is often used in contexts such as radioactive decay, depreciation of value over time, or population decrease in a closed environment, where some quantity decreases by a consistent percentage over equal time intervals.
To solve for y at a given time t, simply substitute the value of t into the function and evaluate the exponential expression. It is important to use a calculator or software tool to evaluate the exponential term accurately when t is not a round number.

a recipe for lemonade calls for 2 cups of sugar for every 1/2 cup of lemon juice. How many cups of sugar would be needed if you had 3 cups of lemon juice?
Answer: 12cups of sugar
Step-by-step explanation:
2cups of sugar = 1/2cup of memo
Xcups of sugar =3cups of lemon
X = 6÷ 1/2
= 12
Answer:
12 cups sugar
Step-by-step explanation:
there are a couple ways to do this...by unit rate or a proportion...
2 cups of sugar for every 1/2 cup of lemon juice
2 / (1/2) = 2 * 2 = 4.....the unit rate is 4/1....or 4 cups of sugar for every 1 cup of lemon.
so if u have 3 cups of lemon, and 1 cup of lemon = 4 cups of sugar, then 3 cups of lemon would equal (4 * 3) = 12 cups of sugar
or set it up as a proportion...
2 cups sugar to 1/2 cup lemon = x cups sugar to 3 cups lemon
2 / (1/2) = x / 3....cross multiply
(1/2)(x) = (3)(2)
1/2x = 6
x = 6 * 2
x = 12 cups sugar
either way u choose to do it will result in the same answer.

| 3y - 3x = -12
Answer:
x=5/2, y=-3/2. (5/2, -3/2).
Step-by-step explanation:
2=2y+5
3y-3x=-12
--------------
2-5=2y
2y=-3
y=-3/2
3(-3/2)-3x=-12
-9/2-3x=-12
3x=-9/2-(-12)
3x=-9/2+12
3x=-9/2+24/2
3x=15/2
x=(15/2)/3
x=(15/2)(1/3)
x=15/6=5/2
The solution for the system of equations is x = -5/2 and y = -3/2.
To solve the system of equations given, one can use substitution or elimination methods. The first equation 2= 2y + 5 can be rearranged to solve for y:
2y = 2 - 5
2y = -3
y = -3/2
Using the second equation 3y - 3x = -12, we substitute y with -3/2 to solve for x:
3(-3/2) - 3x = -12
-9/2 - 3x = -12
3x = -12 + 9/2
3x = -15/2
x = -15/6
x = -5/2
Therefore, the solution for the system of equations is x = -5/2 and y = -3/2.
