a   125600 cm^3

b    327910.2 m^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

a   = 3.14 (20)^2 100

  =125600 cm^3

b  We know the diameter  r =d/2 = 118/2 =59

V = pi r^2 h

         3.14 (59)^2 *30

        327910.2 m^3

Answer:

1) 125,600 cm³

2) 327,910.2 m³

Step-by-step explanation:

Volume of cylinder: pi × r² × h

1) 3.14 × 20² × 100

125,600 cm³

2) 3.14 × (118/2)² × 30

Answer:

The mean of X, μₓ is 2

The standard deviation of X, σₓ is 1.3

Step-by-step explanation:

Here we have the expected value given by the following relation

Expected value = P(x) × n

Where:

P(x) = Probability that the event occurs

n = Number of times the event occurs

The probability of the dice showing 1  = 1/6

The number dice rolled = 12

Therefore, out of 12, the expected number of dice that show 1 in a turn = 12×1/6 = 2

The proportion, p of dice that show 1 = 1/6, hence the mean, μx = np

Standard deviation of a proportion,  [tex]\sigma _x =\sqrt{np{(1 - p)} }[/tex]

Where:

p = 1/6

n = 12

Hence;

μx = 12 × 1/6 = 2

[tex]\sigma _x =\sqrt{np{(1 - p)} } = \sqrt{12 \times \frac{1}{6} (1 - \frac{1}{6}) } = \sqrt{\frac{5}{3} } = 1.29099 \approx 1.3 \ to \ the \ nearest \ tenth[/tex]

Hence the mean and standard deviation of X are presented as follows;

The mean of X, μₓ = 2

The standard deviation of X, σₓ = 1.3.

6:10

2.) 30:50

6*5=30 and 10*5=50

(6:5 is the proportional relationship)

Step-by-step explanation:

Part A: Since the base numbers are 6:5, you can multiply any number like 5 on both sides. They only have to be the same number.

Part B: Divide the numbers until you cannot any more. I divided them both by 6.

Answer:

The answer is D.

Step-by-step explanation:

It have 5 different surface. I will name them as front, back, left, right and down. It's easier for you to see.

Front: 36*50= 1800

Back: 14*36=504

Left: 14*48/2=336

Right:14*48/2=336

Down:36*48=1728

Then, we add everything together and get the answer.

Answer:

Interest = $20

Amount due = $120

Step-by-step explanation:

This is a Simple Interest problem. Simple interest is given as:

I = (P * R * T) / 100

Where I = interest

P = principal or amount loaned

R = rate of interest

T = time elapsed

Ted borrowed $100 from 2 years at a 10% interest rate.

This means that P = $100, R = 10%, T = 2 years.

Hence, the interest will be:

I = (100 * 10 * 2) / 100

I = 2000 / 100

I = $20

The interest after two years will be $20.

Therefore, the total amount due at the end of the loan is:

A = P + I

A = 100 + 20 = $120

The amount due is $120.

Answer:

D.  127

Step-by-step explanation:

Because our spinner is split up evenly 8 ways, we a have a 1/8th chance of getting 6 with any given spin. We will want to pick the number that is the closest to one 1/8th of 1104 from our options at the right.

Let's check them one by one. Note that 1/8 as a decimal is .125, if you are using a calculator to do this problem, decimals will be fastest and we'll work with those here.

A) 291/1104 = .264

B) 117/1104 = .106

C) 209/1104 = .189

D) 127/ 1104 = .115

Our closest number to .125 (ie, 1/8th) is .115. or 127 out of 1,104 spins.

Answer:

D, 127

Step-by-step explanation:

it would be d because if the spinners each have equal spots then you can divide it by 8. which gets you 138, but that isn't an option and its probability so its always around a number. so the closest one is 127 or D

Answer:

D

Step-by-step explanation:

The outlier of 2 decreases the mean page count.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

If the outlier is included in the calculation of the median and mean, then it will affect the measures of central tendency.

However, if the outlier is excluded from the calculation, then it will not affect the measures of central tendency.

If the 2-page introduction chapter is an outlier on the higher side of the distribution, the outlier of 2 increases the mean page count more than the median page count.

If the 2-page introduction chapter is an outlier on the lower side of the distribution, the outlier of 2 decreases the mean page count more than the median page count.

therefore, The outlier of 2 decreases the mean page count.

Answer:

Cut the room into a rectangle and a trapezoid vertically. Then just use the rectangle and trapezoid area formulas to solve.

Step-by-step explanation:

It should work because this is how I find the area of most irregular shapes.

Answer:

To find the area you would first break the shape down into smaller regular shapes. In this case it would be a rectangle and trapezium. Then the next step to working out the area is to work out the area of one of the shapes. In this example i would start with the rectangle as it would be easier. The formula for the area of the rectangle would be length multiplied by the width. Then hold on to the answer. After you would work out the area of the trapezium. The formula for the area of a trapezium is: [tex]\frac{a+b}{2} *height[/tex]. To work this out you would add the lengths of the top line and the bottom line and divide them by 2. Then you would multiply that by the height of the trapezium. After you would add the area of the rectangle and the area of the trapezium and this will give you the total area.

1) Divide the shape into smaller regular shapes.

2) Find the area of the rectangle.

3) Find the area of the trapezium.

4) Add the two areas together.

Answer:

your answer is (1,-6)

Step-by-step explanation:

when a point is reflected in y-axis, then the y-co-ordinate remains same and then x-co-ordinate becomes the opposite of that number.

When you reflect a point across the y-axis, only the x-coordinate changes while the y-coordinate stays the same. For example:

(-x, -y) -> (x, -y)

So:

(-1, -6) -> (1, -6)

Final answer:

To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, the GCD (greatest common divisor) can be used. The GCD between 60 and 8 is 4, and the GCD between 75 and 10 is 5. Thus, the largest number that satisfies the conditions is 4.

Explanation:

To find the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively, we can use the concept of the greatest common divisor (GCD). The GCD is the largest number that divides two or more numbers without leaving a remainder. To find the GCD, we can use the Euclidean algorithm.

First, we divide 60 by 8. The quotient is 7 and the remainder is 4. Then, we divide 8 by 4. The quotient is 2 and the remainder is 0. Since the remainder is 0, we stop here. Therefore, the GCD of 60 and 8 is 4.

Next, we divide 75 by 10. The quotient is 7 and the remainder is 5. Then, we divide 10 by 5. The quotient is 2 and the remainder is 0. Again, since the remainder is 0, we stop here. Therefore, the GCD of 75 and 10 is 5.

Therefore, the largest number that divides 60 and 75 and leaves remainders of 8 and 10 respectively is 4.

Answer:

960 cubes

Step-by-step explanation:

To find how many cubes of side 1 foot can be contained in the room, we have to find the volume of the storage room and then, divide by the volume of the cube.

The storage room is in the shape of a rectangular prism, hence, its volume is:

[tex]V = L * W * H[/tex]

where L = length

W = width

H = height

The dimensions of the storage room are:

10 feet wide, 12 feet long, and  8 feet high

Hence, its volume is:

[tex]V = 10 * 12 * 8 = 960 ft^3[/tex]

The volume of the cube of side 1 foot is:

[tex]V = S^3\\\\V = 1^3 = 1 ft^3[/tex]

Hence, the number of cubes that can be contained in the storage room is:

960 / 1 = 960 cubes

960 cubes can be stored in the storage room.

Answer:

Our system is  :   S + L = 19,  and  3S + 6L = 87

Let # of small rooms = S

# of Large rooms = L

10 Large rooms and 9 Small rooms

Step-by-step explanation:

Let # of small rooms = S

# of Large rooms = L

S + L = 19

3*S + 6*L = 87

Our system is  :   S + L = 19,  and  3S + 6L = 87

solve.

S = 19 - L

3*(19 - L) + 6L = 87

57 - 3L + 6L = 87

57 + 3L = 87

3L = 30

L = 10

S = 19 - 10 = 9
