Answer:
6647.6 liters
Step-by-step explanation:
The volume of a cylinder with end area r and length (or height) h is
V = πr²h
If we substitute 2.3 m for r and 400 m for h, we get:
V = π(2.3 m)²(400 m) = 6647.6 m³ or 6647.6 liters

A) 13 meters
B) 2.3 centimeters
=================================================
Work Shown:
Part A
The ruler diagram shows the building on paper is 6.5 cm wide. The right side of the building lines up with the midpoint marker between 6 and 7.
1 cm = 2 m
6.5*(1 cm) = 6.5*(2 m)
6.5 cm = 13 m is the width of the building in real life
Or you can solve it like this
(1 cm)/(2 m) = (6.5 cm)/(x meters)
1/2 = 6.5/x
1*x = 2*6.5
x = 13
------------------------
Part B
(1 cm)/(2 m) = (x cm)/(4.6 m)
1/2 = x/4.6
1*4.6 = 2*x
4.6 = 2x
x = 4.6/2
x = 2.3 centimeters is the height of the building in the drawing

is dilated from the origin to create segment A prime B prime at A' (0, 6) and B' (6, 9). What scale factor was segment AB dilated by
The scale factor of segment AB was 1.94.
What is scale factor?Scale factor is a number by which a given set of measurements is multiplied in order to increase or decrease the size of the measurements. It can be used to enlarge or reduce the size of an object, image, or diagram. It is a useful tool in many areas of mathematics, including geometry, engineering, and computer graphics.
The scale factor for segment AB can be found by taking the ratio of the lengths of the two segments. To calculate this, use the distance formula to find the length of segment AB and A'B' and set them equal to each other.
The distance formula is: d = √[(x2-x1)^2 + (y2-y1)^2]
The coordinates of A and B are (0, 0) and (6, 9), respectively. The coordinates of A' and B' are (0, 6) and (6, 9), respectively.
For segment AB, the distance formula becomes: d = √[(6-0)^2 + (9-0)^2], which simplifies to d = √[36 + 81], which simplifies to d = √117.
For segment A'B', the distance formula becomes: d = √[(6-0)^2 + (9-6)^2], which simplifies to d = √[36 + 9], which simplifies to d = √45.
The scale factor is then found by taking the ratio of the two distances, √117/√45, which simplifies to √117/3, or approximately 1.94. Therefore, the scale factor of segment AB was 1.94.

Jessica is wanting to buy a 10.00 box of candy. The sales tax is 5%. How much is the total for the candy?
$15.00
$12.00
$11.00
$10.50
Answer: To find the total cost of the candy including the sales tax, we first need to calculate the amount of tax by multiplying the cost of the candy by the tax rate.
The cost of the candy is 10.00.
The tax rate is 5%, which can be written as 0.05.
The total cost of the candy would be
10 + (10*0.05) = 10+0.5 = 10.50
So the correct answer is $10.50.

A financial advisor has recommended two possible mutual funds for investment: Fund A and Fund B. The return that will be achieved by each of these depends on whether the economy is good, fair, or poor. A payoff table has been constructed to illustrate this situation:
STATE OF NATURE
INVESTMENT GOOD ECONOMY FAIR ECONOMY POOR ECONOMY
Fund A $10,000 $2,000 –$5,000
Fund B $6,000 $4,000 0
Probability 0. 2 0. 3 0. 5
Draw the decision tree to represent this situation.
Perform the necessary calculations to determine which of the two mutual funds is better. Which one should you choose to maximize the expected value?
Suppose there is a question about the return of Fund A in a good economy. It could be higher or lower than $10,000. What value for this would cause a person to be indifferent between Fund A and Fund B (i. E. , the EMVs would be the same)?
$21,500 this would be cause a person to be indifferent between Fund A and Fund B (i. E. , the EMVs would be the same)
EMV 1 = 0.2*10,000 + 0.3*2,000 + 0.5*-5,000 = $100EMV 2 = 0.2*6,000 + 0.3*4,000 + 0.5*-0 = $2,400.
Comparing both funds based on EMV calculations, Fund B shows a higher EMV. Therefore, to maximize expected value, we should invest in Fund B with an expected value of $2,400. First, his EMV for Fund A is not the same as Fund A's return being higher or lower in good economic conditions. Therefore, the EMC can also be higher or lower. But obviously the economy changes quickly sometimes. You don't always get the same return. So relying solely on returns is risky. Relying heavily on favorable economic conditions makes Fund A vulnerable to change and increases investor risk, so investors need to be more diversified. We can do the calculation:
Fund A return in good economy = Difference between A and B: EMV (Fund A) = EMV (Fund B) 0.2*X + 0.3(2,000) + 0.5(- 5,000) = 2 4,000.2X = 4,300X = $21,500.
Therefore, if the economy is good, Fund A's return should be $21,500 for there to be indifference between Fund A and the fund B.

Which set of side lengths forms a right triangle?
Answer:
11-60-61
Step-by-step explanation:
For right triangle, leg^2+Another leg^2=hypotenuse^2
11^2+60^2=61^2
Answer:
11 inches, 60 inches, 61 inches
Step-by-step explanation:
This is a right triangle, so the Pythagorean Theorem applies.
The Pythagorean Theorem states that the legs of the triangle, 'a' and 'b'—squared—must equal the hypotenuse, squared.
**Hypotenuse: the longest side of a triangle.**
[tex]a^{2} + b^{2} = c^2[/tex]
This sounds a bit complicated, so allow me to explain this to you.
11 and 60: legs of the triangle.
61: hypotenuse
If I were to plug in the numbers into the formula, it would look like this:
[tex]11^2 + 60^2 = 61^2[/tex]
This is the same as:
[tex]11 * 11 + 60 * 60 = 61 * 61[/tex]
[tex]121 + 3600 = 3721[/tex]
If the legs of the triangle, 121 and 3600, have a sum of the hypotenuse, 3721, then these side lengths can form a right triangle.
The other answer choices, however, do not follow the Pythagorean Theorem.

Complete the following function table for the linear equation y=4x-1
First we can find value of x and. When x=0 then y=-1 and x=1 then y= 3
What is linear equation explain?A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term where m is the slope and b is the y-intercept.So the above given equation is called a "linear equation of two variables," where y and x are the variables.
How do you find the value of Y?Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.
Now we have y= 4x-1
lets x=0 then y= -1
x=1 then y=3
x=2 then y=7
To find slope
y=mx+c
y= 4x-1
so by comparing we can find m=4
Then we can evaluate given equation y=4x-1

What will be the successor of the greatest 7-digit number and the predecessor of the smallest 8-digit number? Is there any relation between these two numbers? If yes, state the relation.
Answer:
The largest 7-digit number, is a 7 nine digits, this number is:
9,999,999
If we subtract one, we get a 7-digit number smaller than this one.
if we add one, we get an 8-digit number.
Then this one is the greatest 7-digit number.
The successor of this number, is equal to the number plus one:
9,999,999 + 1 = 10,000,000
The smallest 8-digit number is the first 8-digit number, and we know that this one is:
10,000,000
And the predecessor is equal to this number minus one:
10,000,000 - 1 = 9,999,999
So we can conclude that:
The successor of the greatest 7-digit is the smallest 8-digit number
The predecessor of the smallest 8-digit number is the greatest 7-digit number.
And we could interpolate this for any N-digit number, such that:
The successor of the greatest N-digit is the smallest (N + 1)-digit number
The predecessor of the smallest (N + 1)-digit number is the greatest N-digit number.
