Solve the equation below for h v=πr^2h
Answer:
The answer is
[tex]h = \frac{v}{πr²} [/tex]Step-by-step explanation:
v = πr²h
To solve for h divide both sides by πr²
That's
[tex] \frac{v}{πr²} = \frac{πr²h}{πr²} [/tex]We have the final answer as

(5x-2)^2 help asap pleaseee
Answer:
25x² − 20x + 4
Explanation:
(5x − 2)²
= (5x + −2)(5x + −2)
= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)
= 25x² − 10x − 10x + 4
= 25x² − 20x + 4

Find the circumference of the circle. Round your answer to two decimal places, if necessary.
Use the Circumference of a Circle Formula:
C = 2πr
or
C = (Diameter)*π (since diameter = 2*radius)
In this case, the diameter is 44 miles
So the circumference is:
C = 44*π = 138.23 miles

the perimeter of a square can be found using P = n + n + n + n, where n is the length of one side of the square. Which equation could also be used to find the perimeter of a square
Answer:
P = 4n
Step-by-step explanation:
P = n + n + n + n
If you combine all the like terms you end up with:
P = 4n
The equation to find the perimeter of a square can also be expressed as 4n, where n is the side.
What is Square?A square is a two dimensional figure which has four vertices, four sides and four angles.
Perimeter of a geometrical figure is the sum of the lengths of the boundary of shape.
Given that n is the length of one side of a square.
Perimeter is the sum of the side lengths.
Since a square has four sides,
Perimeter = 4 times the length of side
= 4n
Hence the perimeter of a square can also be expressed as 4n.

Question 5 Rocko paid $12.50 for 25 game tickets. Louisa paid $17.50 for 35 game tickets. What is the constant of proportionality? Express your answer in decimal form.
Answer: k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
Point R is on line segment QS. Given QS = 16 and QR = 9, determine the length RS.
Answer:
The length RS = 7
Step-by-step explanation:
Here, we are interested in determining the length of RS
Let’s have the line segment arranged as follows;
Q R S
where QR = 9 and QS = 16
From the arrangement, we can deduce that;
QS = QR + RS
Thus;
RS = QS - QR
RS = 16 -9
RS = 7
When x is added to its square, the total is 30. Fond the value of x.
(With solution please)
Answer:
[tex]x=\frac{30}{(1+x)}[/tex]
Step-by-step explanation:
step one:
This is a word problem, we need to translate is it to mathematical terms before we solve
"When x is added to its square, the total is 30"
step two:
[tex]x+x^2=30[/tex]
[tex]x+x^2=30\\\\x(1+x)=30\\\\[/tex]
step three:
divide both sides by 1+x we have the value of x as
