ANSWER
The height is 30 feet
EXPLANATION
The volume of a cylinder is calculated using the formula;
[tex]V = \pi {r}^{2} h[/tex]
The diameter is 24 ft. This implies that the radius of the cylinder is 12ft.
We substitute known values to get:
[tex]4320\pi= \pi{(12)}^{2} h[/tex]
[tex]4320\pi=144 \pi h[/tex]
Divide both sides by 144π
[tex]h = 30ft[/tex]

pLEASE HELP! If z varies inversely as w, and z=5 when w=8, find z when w=10
z=4. If z varies inversely as w, and z=5 when w=8, then when w=10 the value of z is 4.
This exercise is an example of reverse proportionality, Two magnitudes a and b are inversely proportional when there is a constant k such that
a⋅b=k, where constant k is called the proportionality constant.
Then if z varies inversely as w, and z=5 when w=8
z.w=k -------> 5.8=k -------> k=40
So, let's find z when w = 10. With k = 40
z.w=K, clear z from the equation
z=k/w -------> z=40/10 -----> z=4
Final answer:
To find z when w = 10 in an inverse variation equation, we can use the equation z = k/w. By substituting the given values and solving for the constant of variation, we find that when w = 10, z = 4.
Explanation:
To find the value of z when w is 10, we need to use the inverse variation equation. Inverse variation is represented by the equation z = k/w, where k is the constant of variation.
Given that z = 5 when w = 8, we can substitute these values into the equation to find k. 5 = k/8. Solving for k, we get k = 40.
Now, we can substitute the value of k and w = 10 into the equation z = k/w. z = 40/10 = 4. Therefore, when w = 10, z = 4.
what is the measure of secant dc
Answer:
CD = 3
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
CB × CA = CD × CE , that is
4 × (4 + 6.5) = CD × 14
4 × 10.5 = 14CD
42 = 14CD ( divide both sides by 14 )
CD = 3

i^223 is equal to?
[tex]\(i^{223}\)[/tex] is equal to -i.
To find the value of [tex]\(i^{223}\)[/tex], we can use the cycle of powers of i:
[tex]\(i^1 = i\), \(i^2 = -1\), \(i^3 = -i\)[/tex], and [tex]\(i^4 = 1\)[/tex]
The powers of i repeat every four steps.
Therefore, we can express [tex]\(i^{223}\)[/tex] in terms of [tex]\(i^4\)[/tex]:
[tex]\[i^{223} = (i^4)^{55} \cdot i^3\][/tex]
Since [tex]\(i^4 = 1\)[/tex] and [tex]\(i^3 = -i\)[/tex], we have:
[tex]\[i^{223} = 1^{55} \cdot (-i) = -i\][/tex]
How do you write the mixed number 3 2/4 shown as a fraction greater than one
Answer: 14/4
Step-by-step explanation:
since 4/4 is one three would be 12/4. Adding 2/4 to 12/4 is 14/4. So the answer is 14/4
3 2/4 as a mixed number is 14/4
3 multiplied by 4 is 12 and you just add 2 to that and it'll be 14/4

A circular pizza with a diameter of 12 inches is cut along radii into three wedge-shaped slices. The measure of two of the central angles are 80 degrees and 130 degrees. What is the number of square inches in the area of the largest slice? (express your answer in terms of pi)
Answer:
A = 15π in²
Step-by-step explanation:
If two of the central angles are 80° and 130°, totalling 210°, then the third central angle must be (360° - 210°), or 150°.
Let's calculate the area of the entire pizza, whose diameter is 12 in and whose radius is therefore 6 in:
A = πr² → A = π(6 in)² = 36π in².
The area of the largest slice, the one with central angle 150°, is
(150/360) times the total area of the pizza:
A = (150/360)(36π) in², or 15π in²

Find the area of a rectangle whose side lengths are 4x*2and 6x*2-3
Answer:
24x^4- 12x^2 or 12x^2 (2x^2-1)
Step-by-step explanation:
We are given the length and width of the rectangle:
Length=l=4x^2
and
Width=w=6x^2-3
The formula for the area of rectangle is:
Area=length*width
Area=l*w
Putting the values of l and w into the formula:
area=(4x^2 )(6x^2-3)
=24x^(2+2)-12x^2
=24x^4- 12x^2
It can also be written as: taking 12x^2 as common:
=12x^2 (2x^2-1)

A car rental company charges $29 per day to rent a car and $0.15 per mile driven.
a) Write a rule for the total bill B as a function of the number of miles m the car is driven.
b) What is the bill for a 2-day rental if you drove 205 miles?
Answer:
A) C = 29*d + 0.15*m
B) C = $88.75
Step-by-step explanation:
Givens
Let the cost of the rental = C
Let the most of the daily rental = d
Let the cost of the mileage driven = m
Equation
Cost = 29*d + 0.15*m
C = 29*d + 0.15m
Part B
d = 2
m = 205
C = ?
C = 29*2 + 205*0.15
C = 58 + 30.75
C = $88.75
find the percent 133% of 140
The answer would be 186.2.
Answer:
The correct answer is 133% of 140 = 186.2
Step-by-step explanation:
Points to remember
X % of Y is given by
(X/100)*Y
To find 133 % of 140
We have to find 133 % of 140,
According to the formula we can write,
133% of 140 = (133/100) * 140
= 1.33 * 140
= 186.2
133% of 140 = 186.2
Therefore the correct answer is 133% of 140 = 186.2
Please help! Select the correct ordered pairs in the table.
Answer:
(-4, -12) (1, -2) (2, -18)
Step-by-step explanation:
We have a grade 3 polymial function.
We know that the function has a minimum at the point
(-3, -18).
If this is the minimum of the function then this means that when [tex]x <-3[/tex] the function is decreasing and when [tex]x> -3[/tex] the function is growing.
Look in the table for ordered pairs with values of x less than -3.
The only point is (-4, -12).
Then the function has a maximum in ([tex]\frac{1}{3}[/tex], [tex]\frac{14}{27}[/tex])
This means that when [tex]x> \frac{1}{3}[/tex] the function is decreasing and when [tex]x< \frac{1}{3}[/tex] the function is growing.
Search the table for ordered pairs with values of x greater than [tex]\frac{1}{3}[/tex]
We have
(1, -2) (2, -18)
Finally the ordered pairs in which the function decreases are:
(-4, -12) (1, -2) (2, -18)
Observe the attached image.
At 10:00 AM a truck started traveling from point A with a speed of 40mph. 3 hours and 10 minutes later a car started to drive from point A in the same direction with an average speed of 60mph. At what time will the car catch up with the truck?
Answer:
12:07 pm
Step-by-step explanation:
The question is on relative speed
Calculate the distance covered by truck after 3hours and 10 minutes
Given; speed of truck= 40mph
Time the truck took to travel before the car started to drive from point A= 3h 10 minutes
Change hours to minutes= (60×3) + 10 = 190 minutes
Formulae for speed, S=d/t where S is speed of truck, d is distance covered and t is time
if S=d/t then distance d=S×t
d= 40×190/60 =380/3 =126.67 miles
Finding the time the car catch up with the truck
t=d/S where d=126.67 miles and speed of car = 60mph
t= 126.67/60 = 2.11 hours
Change hours to minutes
1 hr=60minutes
2.11 hrs= 2.11×60=126.67 minutes⇒2hrs and 6.67 minutes
t⇒2 hrs 7minutes
Add to the departure time
10.00 + 2: 07 = 12:07 pm
Solve 9(8 - x) = 3x.
Hello - let's do this step by step. Show your work.
You're asking: 9(8−x)=3x.
Now, simplify both sides of the equation.
9(8−x)=3x
(9)(8)+(9)(−x)=3x (To do that, distribute)
72+−9x=3x
−9x+72=3x
Now, subtract 3x from both sides.
−9x+72−3x=3x−3x
Simplify,
−12x+72=0
After, subtract 72 from both sides.
−12x+72−72=0−72
−12x=−72
Last thing, divide both sides by -12.
-12x/12 = -72/-12
Divide.
Therefore, you have x = 6 as your final answer.
Hello there!
9(8-x)=3x
Use the Distributive Property to distribute 9:
72-9x=3x
Move all the variables to the left side. Be sure to use the opposite operation!
-9x-3x=-72
-12x=-72
Divide both sides by 12 in order to isolate x:
x=6

what is the absolute value of 1.7
Answer:
|1.7| = 1.7Step-by-step explanation:
Definition of absolute value:
|a| = a if a ≥ 0
|a| = -a if a < 0
Examples:
|2| = 2
|-2| = -(-2) = 2
|0.45| = 0.45
|-0.45| = -(-0.45) = 0.45
|1000| = 1000
|-1000| = 1000
Therefore
|1.7| = 1.7

Need help with thisssssss
Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
1Kg of grapes cost 5.80 Meagan buys 700 grames of grapes how much does she pay
Meagan pay 4.60
Step-by-step explanation:
1kg------5.80
700g----X
700x5.80=4.60/1=4.60
Final answer:
To find the cost of 700 grams of grapes, divide the cost of 1 kilogram by 1000 to get the price per gram, then multiply by 700. Meagan pays $4.06 for 700 grams of grapes.
Explanation:
To calculate how much Meagan pays for 700 grams of grapes when 1 kilogram (1000 grams) of grapes costs $5.80, we first find out the cost per gram. Then we multiply the cost per gram by the amount of grams Meagan is buying.
The cost per gram is: $5.80 / 1000 grams = $0.0058 per gram.
So for 700 grams, Meagan pays: $0.0058 per gram × 700 grams = $4.06.
Therefore, the cost of 700 grams of grapes is $4.06.
