Final answer:

The volume of the cylinder with a base diameter of 16 inches and a height of 7 inches is approximately 1407.36 cubic inches. This is calculated using the formula V = πr²h.

Explanation:

To calculate the volume of a cylinder with a base diameter of 16 inches and a height of 7 inches, we use the volume formula V = πr²h. First, find the radius r by halving the diameter, which gives us 8 inches. Then, square the radius and multiply by π (approximately 3.1416) and the height.

V = π × (8 inches)² × (7 inches)

V = π × 64 inches² × 7 inches

V = π × 448 inches³

V ≈ 3.1416 × 448 = 1407.36

The volume of the cylinder is approximately 1407.36 cubic inches.

Final answer:

The volume of a cylinder with a base diameter of 16 inches and a height of 7 inches is 1,408 cubic inches, calculated using the formula V = πr²h.

Explanation:

To calculate the volume of a cylinder with a base diameter of 16 inches and a height of 7 inches, we first need to find the radius of the cylinder's base. The radius (r) is half of the diameter, so for this cylinder, the radius is 8 inches. We then apply the formula for the volume of a cylinder, which is V = πr²h.

Using the values provided:

Calculate the radius: radius = diameter / 2 = 16 inches / 2 = 8 inches.

Compute the volume: V = π * (8 inches)² * 7 inches.

Since π is approximately 3.14159, the calculation is V = 3.14159 * 64 inches² * 7 inches = 1,408 cubic inches.

Therefore, the volume of the cylinder is 1,408 cubic inches.

Answer:

17 1/2 months or rounded up to 18

Step-by-step explanation:

so first you need to set up an equation,

lets do company Q first..

because the monthly fee is 3 bucks thats gonna be the number that goes hand in hand with x so lets put that down

Q - 3x

now we have to add our one time fee of 25 dollars

Q - 3x + 25 .. bam thats our first equation

lets do the same thing for our next company

W - x + 60

( because the fee is one dollar, theres no reason to put 1x, its not mathematically correct, so we just leave it as x )

so now we have to set up the equation together, and because we are trying to find when the two will meet and have an EQUAL cost we make them equal to each other

so

3x + 25 = x + 60

if you solve it...

2x + 25 = 60

2x + 35

x = 17.5

AC = 215,000 km

Step-by-step explanation:

I've attached a diagram that depicts this 3 moons and the planet in regards to their positions.

We need to find the distance AC as shown in the image.

We are given that AM and NC = 100,000 km

And diameter; MN = 15,000km

Thus,AC = MN + NC

AC = 15000 + 100,000 + 100000 = 215,000 km

Answer:

The weight of the brick is 60 ounce to the nearest ounce

Step-by-step explanation:

In this question, we are asked to calculate the weigh of Lou’s brick given the dimensions of the shape of the brick and the weight of the clay.

To answer this question quite aptly, we need to know exactly the volume of the rectangular prism given the dimensions we have in the question.

To calculate this volume , we simply use the measurements we have to get it.

mathematically the volume of a rectangular prism is simply V = w * h * l

where w , h and l are width, height and length respectively.

now let’s calculate!

V = 3.5 * 2.25 * 8 = 63 inches^3

Now we need to know what the brick weigh in ounce. We already have the weight of the clay. now this is equal to the volume of the brick divided by the weight of the clay.

Mathematically this is = 63/1.055 = 59.72 ounce which is 60 ounce to the nearest ounce

Answer:

60 ounce

Step-by-step explanations:

The volume of a rectangular prism is length multiplied by width and the height.

And if the width is 3.5 inches

Length is 8 inches

Height of 2.25 inches

V = 2.25 × 8 × 3.5

= 63 in³

And since the clay weighs 1.055 oz/in³,the total weight of the clay brick will be derived by dividing the volume of the brick by its weight per in³

63/1.055

= 59.7 and to the nearest whole number = 60 ounce

The first step in simplifying is to distribute the -b and -1 to the terms in the parentheses.

The abbreviation PEMDAS stands for parentheses, exponents, multiply or divide, add or subtract, which stands for the sequence of operations in mathematics. To achieve the right result when an expression contains many operations, it's crucial to compute them in the correct sequence (exponents after the parenthesis, etc.).

Given equation 3-b(7b+ 2) + 3b - (11 - b). As we can see that in this equation there is nothing complicated inside the bracket to simplify. so we will jump to the next step which is to distribute the -b.

Hence, in equation 3-b(7b+ 2) + 3b - (11 - b) first step in simplifying is to distribute the -b and -1 to the terms in the parentheses.

Answer:

Interest: $390 | Total: $715

Step-by-step explanation:

To answer the first question, we can use the simple interest formula provided:

[tex]I=Prt[/tex]

P = initial balance

r = annual interest rate

t = time

First, change 8% into the decimal form:

8% -> [tex]\frac{8}{100}[/tex] -> 0.08

Now, plug in the values:

[tex]I=325(0.08)(15)[/tex]

[tex]I=390[/tex]

Charlie made $390 of interest. To find the total, just add that number to $325.

[tex]390+325=715[/tex]

Charlie's total money made was $715.

Final answer:

Charlie earns $390 in simple interest over 15 years. The total future amount, including the initial investment, is $715 after 15 years.

Explanation:

To determine how much interest Charlie's initial investment will earn over the 15-year period, we apply the simple interest formula, I = P rt, where I stands for interest, P is the principal amount, r is the rate of interest per year, and t is the time in years. Plugging in Charlie's investment details: I = $325(0.08)(15).

First, calculate the annual interest: $325  imes 0.08 = $26 per year. Then, multiply the annual interest by the number of years: $26  imes 15 = $390.

Therefore, the total simple interest earned over the 15-year period is $390.

To calculate the total future amount, add the interest earned to the initial investment: Total future amount = Principal amount + Interest = $325 + $390 = $715.

After 15 years, Charlie will have $715 in his account.

y = ax² + c thru (-1,4) and (0,8)

Substituting in the coordinates of each point for x and y gives two equations:

4 = a  (-1)² + c

8 = a (0²) + c = c

From the second one we see c=8.  Substituting into the first one,

4= a + 8

a = 4-8 = -4

Answer: a=-4, c=8

Check:

f(x) = -4x² + 8

f(0) = 8, good

f(-1) = -4(1) + 8 = 4, good

Final answer:

To find the values of a and c for the parabola through points (-1, 4) and (0, 8), we substitute these points into the equation y = ax² + c. This gives us two equations, and by solving them, we find that a = -4 and c = 8.

Explanation:

To find the values of a and c for the parabola y = ax² + c that passes through the points (-1, 4) and (0, 8), we can use these points to set up two equations:

1. For the point (-1, 4), substituting into the equation y = ax² + c, we get: 4 = a(-1)² + c 4 = a + c

2. For the point (0, 8), substituting into the equation y = ax² + c, we get: 8 = a(0)² + c 8 = c

From the second equation, we can see that c = 8. Using this information in the first equation, we substitute c to find a: 4 = a + 8 -4 = a

Therefore, the values for the parabola that passes through the given points are a = -4 and c = 8.

Answer:

a)   0.71

b)   0.9863

Step-by-step explanation:

a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000

-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:

[tex]P(X<500,000)=P(X=0)+P(X=500)\\\\=0.34+0.37\\\\=0.71[/tex]

Hence, the probability of a house price below $500,000 is 0.71

b. -Let X be the mean price of a randomly selected house.

-Since the sample size 40 is greater than 30, we assume normal distribution.

-The probability can therefore be calculated as follows:

[tex]P(X<x)=P(z<\frac{\bar X-\mu}{\sigma/\sqrt{n}})\\\\P(X<500,000)=P(z<\frac{500-403}{278/\sqrt{40}})\\\\=P(z<2.2068)\\\\\\=0.9863[/tex]

Thus, the probability  that the mean value of the 40 houses is less than $500,000 is 0.9863

Should be 5,100 from the information that is given.

Question;

Assumption:

Let us assume Brandon's running speed is = 18.30 and

Ruben's running speed is = 16.50 and

Answer:

The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;

Brandon → Y₁ = 18.3·X₁ and

Ruben → Y₂ = 16.5·X₂

Step-by-step explanation:

The equation is of the form

Y = 17.45·X

That is Amy ran Y meters in X seconds

Therefore we have

[tex]17.45 = \frac{Y}{X}[/tex] or the value 17.45 is the running speed of Amy

Therefore, where the running speed of Brandon is 18.30  and the running speed of Ruben is 16.50  we have

Y meters ran by Brandon in X seconds given by

Y₁ = 18.3·X₁ and

For Ruben we have Y meters ran in X seconds given by

Y₂ = 16.5·X₂.

Answer:

Brandon : Y = BX, where B is the speed (positive integer) and X is the time in seconds.

Ruben : Y = RX, where R is the speed (positive integer) and X is the time in seconds.

Step-by-step explanation:

For Amy, the relationship between the distance run and the time taken is represented by the equation Y equals 17.45X, where she ran Y meters in X seconds.

Therefore we have,

Y = 17.45X

Y/X = 17.45 m/s, where m/s is meter per second.

Let us assume that the speed for Brandon is represented by B and that of Ruben is represented by R.

For Brandon, we obtain Y/X = B m/s

Y = BX

For Ruben, we obtain Y/X = R m/s

Y = RX

Answer: The volume is 40 cubic inches

Step-by-step explanation: Each toy block is 1 cubic inch, which means each toy block is a cube with all sides (Length, width and height) measuring 1 inch. That makes the volume of each cube or block to be derived as;

Volume = L x W x H

Volume = 1 x 1 x 1

Volume = 1 cubic inch

The first 3 floors are made up of six rows of four blocks. This means, the first 3 floors has six by four blocks, that is, six times four blocks and that gives us 24 blocks.

The fourth to eighth floors are made up of four rows of four blocks. This also means four by four blocks, that is, four times four blocks and that gives us 16 blocks.

Having determined the amount of blocks used in the total model building as

1st - 3rd = 24 blocks

4th - 8th = 16 blocks

The total number of blocks used is 24 plus 16 which equals 40. Having been told that each block has a volume of 1 cubic inch, the volume of the model building equals 40 cubic inches.
