The surface area of a cylinder is approximately 240.33 square inches.

The formula for the surface area of a cylinder is A = 2πr² + 2πrh, where r is the radius and h is the height of the cylinder.

Given the 24-inch cylindrical tube and its base has a 3-inch diameter.

Here,

Radius r = 3/2 = 1.5 inches

Height h = 24 inches

To determine the surface area of the container, substitute the given values for r = 1.5 and h = 24:

A = 2π(1.5)² + 2π(1.5)(24)

A = 2π(2.25) + 72π

A = 4.5π + 72π

A = 76.5π

We can approximate π as 3.14, then

A ≈ 76.5× 3.14

Apply the multiplication operation, and we get

A = 240.33 square inches

Thus, the surface area of a cylinder is approximately 240.33 square inches.

(a) The profit function is found by subtracting the cost function from the revenue function. In this case, the profit function P(x) can be found by subtracting C(x) from R(x):

P(x) = R(x) - C(x) = (−1x^2+370x) - (5x+2400)

Simplifying the expression gives:

P(x) = -1x^2 + 370x - 5x - 2400

P(x) = -1x^2 + 365x - 2400

Therefore, the profit function is P(x) = -1x^2 + 365x - 2400.

(b) The average profit function is found by dividing the profit function by the number of items sold, x. In this case, the average profit function Pˉ(x) can be found by dividing P(x) by x:

Pˉ(x) = P(x) / x = (-1x^2 + 365x - 2400) / x

Simplifying the expression gives:

Pˉ(x) = -1x + 365 - 2400/x

Therefore, the average profit function is Pˉ(x) = -1x + 365 - 2400/x.

Answer: $460

Step-by-step explanation:

To calculate the total amount of money you will pay back after borrowing $400 for 5 years at an annual interest rate of 3%, you can use the following formula:

Total amount = principal + interest

Principal = the amount you borrowed = $400

Interest = the amount of interest paid over the 5 years period.

To calculate the interest, we can use the formula:

Interest = Principal x Rate x Time

Rate = the annual interest rate expressed as a decimal = 0.03

Time = the time period in years = 5

So, the interest for the 5-year period is:

Interest = $400 x 0.03 x 5 = $60

Therefore, the total amount of money you will pay back is:

Total amount = $400 + $60 = $460

You will pay back $460 over five years if you borrow $400 at an annual interest rate of 3%.

Answer: To calculate the total amount of money to be paid back for borrowing $400 for 5 years at an annual interest rate of 3%, we need to use the formula for simple interest:

Simple interest = Principal x Rate x Time

where:

Principal = $400 (the amount borrowed)

Rate = 3% per year

Time = 5 years

Plugging these values into the formula, we get:

Simple interest = $400 x 0.03 x 5

= $60

Therefore, the total amount of money to be paid back is the sum of the principal and the simple interest:

Total amount = Principal + Simple interest

= $400 + $60

= $460

So, you will need to pay back a total of $460 after 5 years of borrowing $400 at an annual interest rate of 3%.

Answer:

-14 gallon jugs

- 10 half-gallon jugs

Step-by-step explanation:

I'm not an expert at solving these algebraically, so I'm going to do this the old-fashioned way: Guess and Check.

Lets sum up our information:

- He bought 19 gallons

- He bought those 19 gallons with 24 jugs

- There are half-gallon and full gallon jugs

We know that if he bought 24 full gallon jugs, he would have 24 gallons of milk, but he only has 19, so this is not the answer

We know that if he bought 23 full gallons jugs and one half-gallon jug, he would have 23.5 gallons of milk, but he only has 19 gallons of milk, so this is also not the answer.

We keep reducing the number of full gallon jugs and increasing the number of half-gallon jugs until we reach 19 gallons total.

After trying different combinations, we can figure out that he bought

-14 gallon jugs

- 10 half-gallon jugs

The answer is 5(2y-3).

Factorization is an easy process wherein you just need to find out the common factors and solve your question as per requirement.

To factor 10y-15, we need to find the greatest common factor (GCF) of the two terms. The greatest common factor (GFC) of 10 and 15 is 5. We can then factor out the GCF from each term to get:

10y-15 = 5(2y-3)

where 5 is a whole number greater than 1.

So the answer as a product with a whole number greater than 1 is 5(2y-3).

104 consumers bought at least one of the three labels, 12 consumers bought labels A and B but not C 44 consumers bought label A and 91 consumers bought none of these labels because of the equations.

To find the number of consumers who buy the product sold under at least one of the three labels, we need to add up the number of consumers who buy the product under each label individually and those who buy the product under multiple labels.

However, we need to be careful not to double count those who buy the product under all three labels. Therefore, the formula for this calculation is:

At least one of the three labels = (A only) + (B only) + (C only) + (A and B only) + (A and C only) + (B and C only) + (A, B, and C)

Plugging in the given values, we get:

At least one of the three labels = 15 + 20 + 28 + 12 + 9 + 12 + 8 = 104 consumers

To find the number of consumers who buy the product sold under labels A and B but not C, we simply use the value given for those who buy only those sold under labels A and B:

Labels A and B but not C = 12 consumers

To find the number of consumers who buy the product sold under label A, we need to add up the number of consumers who buy the product under label A individually and those who buy the product under label A and one or both of the other labels. Therefore, the formula for this calculation is:

Label A = (A only) + (A and B only) + (A and C only) + (A, B, and C)

Plugging in the given values, we get:

Label A = 15 + 12 + 9 + 8 = 44 consumers

Finally, to find the number of consumers who buy the product sold under none of these labels, we subtract the number of consumers who buy the product under at least one of the three labels from the total number of consumers surveyed:

None of these labels = Total consumers - At least one of the three labels = 195 - 104 = 91 consumers

Answer:

burrito $3.00 , taco $1.50

Step-by-step explanation:

using the variables b and t for burrito and taco , then

2t + 2b = 9 → (1)

t + 3b = 10.5 → (2)

multiplying (2) by - 2 and adding to (1) will eliminate t

- 2t - 6b = - 21 → (3)

add (1) and (3) term by term to eliminate t

(2t - 2t) + (2b - 6b) = 9 - 21

0 - 4b = - 12

- 4b = - 12 ( divide both sides by - 4 )

b = 3

substitute b = 3 into either of the 2 equations and solve for t

substituting into (1)

2t + 2(3) = 9

2t + 6 = 9 ( subtract 6 from both sides )

2t = 3 ( divide both sides by 2 )

t = 1.5

1 burrito costs $3.00 and 1 taco costs $1.50

Answer:

The answer is C

The principal is 50 and the rate of interest is 0.4.

The principal (P) and the rate of interest (R) can be calculated using the following equations:
P = (400*2)/(440 - 400)
R = (440 - 400)/(P*2)
Substituting the given values in the equations we get:
P = 2000/40 = 50
R = 40/100 = 0.4

To calculate the rate and principal of the sum of money, we can use the formula for simple interest: I = Prt, where I is the interest, P is the principal, r is the rate, and t is the time in years.
Given that the yearly interest for the first year is 400 and for the second year is 440, we can set up two equations:
400 = Prt
440 = Pr( t + 1)
Since the interest is for two consecutive years, the time in the first equation is t and the time in the second equation is t + 1.

We can rearrange the first equation to solve for P:
P = 400 / rt
Substituting this value of P into the second equation gives us:
440 = (400 / rt)( t + 1)
Simplifying and rearranging gives us:
440rt = 400t + 400
40rt = 400
rt = 10

Since we are looking for the rate and principal, we can substitute the value of rt back into the first equation:
400 = P(10)
P = 40
So the principal is 40 and the rate is 10 / t. To find the rate, we can substitute the value of P back into the first equation and solve for t:
400 = 40(10 / t)
t = 10
So the rate is 10 / 10 = 1.

An exponent is a numerical value that indicates how many times a number, variable, or expression is to be multiplied by itself. It is usually written as a superscript to the right of the base, such as in the expression 3², where 3 is the base and 2 is the exponent.

The exponent indicates that 3 is to be multiplied by itself 2 times, resulting in a value of 9. Exponents are used in many areas of mathematics, including algebra, calculus, and geometry, and are an important concept for understanding mathematical operations and functions.

To simplify the expression, we need to follow the order of operations and combine like terms where possible:

2/3(3x - 1) + 4x + 3² - 10x + 5

First, simplify the expression inside the parentheses:

2/3(3x - 1) = 2x - 2/3

Next, simplify the squared term:

3² = 9

Now, combine the like terms:

2x - 2/3 + 4x - 10x + 9 + 5 = -4x + 14 + 2/3

Finally, we can rewrite the expression with the fractional coefficient as a mixed number:

The equation of the tangent line to the curve at the point (1, 3) is y = (3/2)x + 1/2.

To find the equation of the tangent line to the curve at a given point, we first need to find the slope of the tangent line at that point. We can do this by finding the derivative of the curve, which is given by y'(x) = 3x² / 2(2+x³)^(1/2).

Next, we need to find the coordinates of the point at which we want to find the equation of the tangent line. Let's say we want to find the equation of the tangent line at the point (1, 3).

Now, we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is given by y - y1 = m(x - x1), where m is the slope of the line, and (x1, y1) is a point on the line.

Plugging in the values for the slope and the point, we get:

y - 3 = (3(1)²/ 2(2+(1)³)^(1/2))(x - 1)

Simplifying the equation, we get:

y - 3 = (3/2)(x - 1)

y = (3/2)x + 1/2

So, the equation of the tangent line to the curve at the point (1, 3) is y = (3/2)x + 1/2.

Dividing the fraction (x - 2) / (3x - 21) by (5x - 10) / (9x - 63) will result to 3/5.

To divide two fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is simply the fraction flipped upside down. So, the reciprocal of the second equation (5x - 10) / (9x - 63) is (9x - 63) / (5x - 10). Now we can multiply the two fractions together to get the answer.

(x - 2) / (3x - 21) × (9x - 63) / (5x - 10)

= [(x - 2)(9x - 63)] / [(3x - 21)(5x - 10)]

Now we can simplify the numerator and denominator by factoring out the common factors:

= (9x - 63)(x - 2) / (3x - 21)(5x - 10)

= (3)(3x - 21)(x - 2) / (3x - 21)(5)(x - 2)

Let's start by using the information given in the problem to write an equation for the perimeter of the rectangle:

Perimeter = 2(length + width)

We know that the length of the rectangle is twice its width, so we can write:

length = 2*width

Substituting this expression into the equation for the perimeter, we get:

Perimeter = 2(2*width + width)

Simplifying this expression, we get:

Perimeter = 6*width

We are given that the perimeter is 7 1/3 cm, which we can convert to a mixed number:

Perimeter = 7 + 1/3 = 22/3

Substituting this value into the equation above, we get:

22/3 = 6*width

Solving for the width, we get:

width = 22/3 ÷ 6 = 11/9

Now that we have the width, we can use the expression for the length to find its value:

length = 2*width = 2(11/9) = 22/9

Finally, we can use the formula for the area of a rectangle, A = length * width, to find the area:

A = (22/9) * (11/9) = 242/81 square cm

Therefore, the area of the rectangle is 242/81 square cm.
