Answer:
C. V = π(2.5)²h
Volume = 19.6h
Step-by-step explanation:
Radius (r) of cylinder = ½ of 5 = 2.5 in.
Height (h) = h in.
Volume of a cylinder = πr²h
Equation that can be used to find B:
Plug in the values into the volume formula
V = π(2.5)²h
Volume = 19.6h

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the process is 20%. Thoroughly testing a chip to determine whether it is good or bad is rather expensive, so a cheaper test is used. All good chips will pass the test, but so will 6% of the bad chips. a) (4 points) What is the probability that a randomly chosen chip will pass the test
Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
a) (4 points) What is the probability that a randomly chosen chip will pass the test
[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]
0.812 = 81.2% probability that a randomly chosen chip will pass the test

Last Friday Trevon had $29. Over the weekend he received some money for cleaning the attic. He now has $41. How much money did he receive?
A. 29 - n = 41
B. 29 - n = 40
C. 29 + n = 41
D. 29 + n = 40
Answer:
C
Step-by-step explanation:
Trevon started with $29.
After cleaning, his total rose to $41.
Since he received money, we add that amount (n) to his initial amount of money ($29), to equal his total amount ($41)

Question 1) Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x - 3y = 13, x + 2y = -4. ( I'll post a picture of the question and problem incase there's any confusion). Will Mark Brainliest.
Answer:
x = 2 and y = -3
Step-by-step explanation:
The given equations are:
2x - 3y = 13 ...(1)
x + 2y = -4 ...(2)
Multiply equation (2) by 2.
2x + 4y = -8 ...(3)
Subtract equation (3) from (1).
2x - 3y-(2x + 4y) = 13-(-8)
2x-3y-2x-4y = 13+8
-7y = 21
y = -3
Put the value of y in equation (2).
x + 2(-3) = -4
x-6=-4
x = 6-4
x = 2
So, the solution of the given equations are x = 2 and y = -3.

Answer:
6 cups of bananas
Step-by-step explanation:
there are 9 cups of apples, so 3 cups of apples need to be multiplied by three. that means you have to multiply the 2 cups of bananas by three.

Given :
segment AE and segment BD bisect each otherWhich means :
∠BCA and ∠DCE are equal because they are vertically opposite angles. Segment AC = segment CE because the bisector BD divides the segment AE into two equal parts which are segment AC and segment CE.segment BC and segment CD will be equal because bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.Since two sides and one included angle is equal △ACB≅△ECD under the SAS congruence criterion .
Given a point translated from A(1,2) to B(4,4). If a point C at (0,0) is translated in the same way, what will be its new endpoints?
A.(−3,−2)
B.(3,2)
C.(2,2)
D.(3,3)
Answer:
B.(3,2)
Step-by-step explanation:
Point translated from A(1,2) to B(4,4).
This means that for x, we add 3 units(4 - 1 = 3), while for y, we add two units(4 - 2 = 2).
If a point C at (0,0) is translated in the same way, what will be its new endpoints?
0 + 3 = 3
0 + 2 = 2
So
B.(3,2)

The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find the length that beats 80seconds and the time of a pendulum with length 36cm
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.

A pair of shoes that originally sold at $30 is now being offered at a 25% discount.
What is its present price?
Answer:
$22.5
Step-by-step explanation:
You will pay $22.5 for a item with original price of $30 when discounted 25%.
Answer:
Refer to explanation
Step-by-step explanation:
The screenshot you put is the correct answer, here's another method to get the same answer:
Find what 25% is.
100% = 30
1% = 30 ÷ 100 = 0.30
25% = 0.30 x 25 = 7.50
Find the price after the 25% discount.
100 - 25 = 75
75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)

PLS I NEED HELP! Which graph grows the fastest as x gets larger?
A. y = 3^x
B. y = 5^x
C. y = 4^x
D. y = 2^x
Answer:
y=5^x
Step-by-step explanation:
5 to whatever power will always be larger than 4, 3, or 2.
For example:
3 squared = 9
5 squared = 25
4 squared = 16
2 squared = 4
25 is greater than 9, 16, and 4
