Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h
Answer:
C
Step-by-step explanation:
we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.
so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.
therefore, dividing both sides by pi is a good first step.

Step-by-step explanation:
Water is flowing into an inverted cone, of diameter and height 30 cm at a rate of 4 litres per minute. How long, in seconds,
will it take to fill the cone?
1st question : volume to be filled in liter ?
V cone = 1/3 x base area x h
= 1/3 x pi x r² x h
= 1/3 x 3,14 x (30:2)² x 30
= 1/3 x 3,14 x 15² x 30
V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters
then
we know 4 liters .............1 minute
we are looking for 7 liters............. n minute
4 x n = 7 x 1
n = 7/4
n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec
Is 2 squared + 3 squared = 4 squared a true statement? Explain.
Answer:
It is not true it is false.
Step-by-step explanation:
since 2^2+3^2=4^2
4+9=16
13≠16
Step-by-step explanation:
No.
2² + 3² = 4 + 9 = 13.
4² = 16.
13 ≠ 16.

Keep it, change it, flip it...
keep the first fraction the same, change the division into a multiplication sign, then flip the numerator and denominator of the second fraction.
It should look like this.
3/8 x 9/4
Solve and you should get 27/32

explain the steps in finding the midpoint of the points (-1,2) and (3,-6). The state the midpoint
Answer:
(1, -2)
Step-by-step explanation:
midpoint x = (x₁ + x₂) / 2
midpoint y = (y₁ + y₂) / 2
[tex](\frac{-1 + 3}{2} , \frac{2 + -(6)}{2} )[/tex]
= (1, -2)
The midpoint of the points (-1,2) and (3,-6) is (1, -2).
What is Midpoint?
To find the midpoint of numbers, add two numbers and divide by 2.
Given that;
Two points are (-1,2) and (3,-6).
Now,
Let midpoint of the points (-1,2) and (3,-6) is (x, y)
The value of x = (-1 + 3)/2
= 2/2
= 1
And, The value of y = (2 + (-6))/2
= -4/2
= -2.
Thus, The midpoint of the points (-1,2) and (3,-6) is (1, -2).

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(7) = -1 B. g(0) = 2 C. g(-4) = -11 D. g(-13) = 20
Answer:
The correct option is;
D. g(-13) = 20
Step-by-step explanation:
The given information are;
The domain of the function, g is given as -20 ≤ x ≤ 5
The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45
g(0) =-2 and g(-9) = 6
Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9
Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1
Therefore, we can get either;
g(-13) = 20 or g(7) = -1
However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true
How do you use the GCF to write equivalent fractions?
Answer:
Step-by-step explanation:
To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.Oct 4, 2021
Tiana has 2 2/3 gallons of paint. She uses 1/2 of the total amount to paint her room. She gives of the remaining paint to her brother. How many gallons of paint does Tiana give to her brother?
Answer:
2 1/6
Step-by-step explanation:
How we calculate this is make the two fractions denominators the same so we can make them both 6.
for the 3 we times it by 2 and 2 by 3.
so our 2 fractions are now 2 4/6 and 3/6 Now
so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6
Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.
Hope it helps have a great afternoon:)

Find the size of angle XYZ. Give your answer to 1 decimal point. Z 13cm X 4cm Y
Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°
What is the Tangent Ratio?The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.
Thus:
∅ = ∠XYZOpposite side = 13 cmAdjacent side = 4 cmThus:
tan (m∠XYZ) = 13/4
m∠XYZ = tan^-1(13/4)
m∠XYZ = 72.9°
