A 14-inch-wide conveyor unloads 4000 bushels of wheat per hour. At this speed, how many bushels per hour will an 21-inch-wide conveyor unload?
An 21-inch-wide conveyor would unload
Answers
Answer:
6000 bushels per hour.
Step-by-step explanation:
Let's assume that the rate at which the conveyor unloads wheat is proportional to its width.
If a 14-inch conveyor unloads 4000 bushels per hour, we can write this as:
Rate = 4000 bushels/hour * (Width of conveyor) / 14 inches
Now, if we want to find the rate at which an 21-inch conveyor would unload wheat, we can simply plug in the width into the equation:
Rate = 4000 bushels/hour * (21 inches) / 14 inches
Rate = 6000 bushels/hour
Therefore, an 21-inch-wide conveyor would unload 6000 bushels per hour.

If a translation is applied to square ABCD, the y-coordinate of B' = y_coordinate of B - 8 = -8.
What is the translation?
The translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.
When a translation of T-3, -8 is applied to square ABCD, it means that each point in the square is moved 3 units to the left and 8 units down.
The y-coordinate of B is found by moving 8 units down from the original y-coordinate of B.
Therefore, If a translation is applied to square ABCD, the y-coordinate of B' = y_coordinate of B - 8 = -8.

Answers
The quadratic formula is ax^2 + bx + c = 0, so we need to check if the given equations can be rewritten in this form.
x^4 – 6x^2 – 27 = 0 is quadratic in form, since it can be rewritten as (x^2)^2 - 6(x^2) - 27 = 0, where a = 1, b = -6, and c = -27.
3x^4 = 2x is not quadratic in form, since it can be simplified to 3x^3 = 2, which is not in the form ax^2 + bx + c = 0.
2(x + 5)^4 + 2x^2 + 5 = 0 is not quadratic in form, since it contains a fourth power term and the variables x and (x + 5) are not combined in a quadratic manner.
6(2x + 4)^2 = (2x + 4) + 2 can be simplified to 24x^2 + 44x - 10 = 0, which is quadratic in form, since it can be rewritten as 24x^2 + 44x - 10 = 0, where a = 24, b = 44, and c = -10.
6x^4 = -x^2 + 5 is not quadratic in form, since it contains a fourth power term and a linear term, which are not combined in a quadratic manner.
8x^4 + 2x^2 – 4x = 0 is quadratic in form, since it can be rewritten as 8(x^2)^2 + 2(x^2) - 4x = 0, where a = 8, b = 2, and c = 0.
Therefore, the quadratic equations in the given set are x^4 – 6x^2 – 27 = 0, 6(2x + 4)^2 = (2x + 4) + 2, and 8x^4 + 2x^2 – 4x = 0.

Show that if f is analytic in a domain D and |f(z)|| is constant in D, then the function f(z) is constant in D
Answers
Because f is analytic variable in D, it is differentiable, and every place in D has a zero derivative. Therefore, f in D must be constant.
A function f must be differentiable in the domain D if it is analytic there. The derivative of f must therefore exist and be continuous in D. The derivative of f must be zero everywhere in D if the absolute value of f, |f(z)|, is constant in D since the derivative of an absolute value of a function is always zero. As a result, f must be constant in D since the derivative of f is zero everywhere in D. Due to the fact that the derivative of |f(z)| is always zero, this holds true regardless of the value of |f(z)|. As a result, the function f(z) is constant in the domain D if f is analytical in D and |f(z)| is constant in D.

C. 1.35%
D. 13.5%
Answers
A correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.
What is the interest rate?
Interest rate is the amount charged over and above the principal amount by the lender from the borrower. In terms of the receiver, a person who deposits money to any bank or financial institution also earns additional income considering the time value of money, termed as interest received by the depositor.
The interest rate in a lease can be calculated using the money factor, which is essentially a type of interest rate used in auto leasing.
To calculate the interest rate from the money factor, multiply the money factor by 2400.
In this case, the money factor is 0.00324, so the interest rate would be:
0.00324 * 2400 = 7.776%
Therefore, the correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.

A correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.
Which interest rate is it?The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
The money factor, which is essentially a sort of interest rate utilized in auto leasing, can be used to compute the interest rate in a lease.
By multiplying it by 2400, you can determine the interest rate from the money element.
Given that the money component in this situation is 0.00324, the interest rate would be:
The result of three consecutive conversions from an interest rate to a money factor is 2400 (1/2 × 1/12 × 1/100). 6/2400 = 0.0025 money factor, which can be multiplied by the entire amount borrowed to see how much the monthly interest would be roughly.
(1/2 × 1/12 × 1/100). 6/2400 = 0.0025
0.00324 × 2400 = 7.776%

A bus company is replacing all the old seats in its buses with new ones. The company owns 13 buses and each bus has 28 seats. It costs $89.40 to purchase
each new seat, as well as an additional $31.70 to install each new seat. What is the total cost the company will pay?
Answers
Answer:
$44.236.20
Step-by-step explanation:
First, we need to calculate the cost of purchasing new seats for all the buses. The company has 13 buses and each bus has 28 seats, so the total number of seats to be replaced is 13 * 28 = 364 seats. The cost of purchasing each seat is $89.40, so the total cost of purchasing new seats for all the buses is 364 * $89.40 = $32,610.40.
Next, we need to calculate the cost of installing new seats for all the buses. The cost of installing each seat is $31.70, so the total cost of installing new seats for all the buses is 364 * $31.70 = $11,625.80.
Finally, we need to add the cost of purchasing and installing new seats to get the total cost the company will pay. The total cost of purchasing new seats is $32,610.40 and the total cost of installing new seats is $11,625.80, so the total cost the company will pay is $32,610.40 + $11,625.80 = $44,236.20.

[tex]m^3+3m^2+3m+1[/tex]
Step-by-step explanation:
[tex](m^2+2m+1)(m+1)=(m^2)(m)+(m^2)(1)+(2m)(m)+(2m)(1)+(1)(m)+(1)(1)=m^3+m^2+2m^2+2m+1m+1=m^3+3m^2+3m+1[/tex]
You could also use the binomial theorem because the expression is equivalent to [tex](m+1)^3[/tex] but either method works.

Which relationship between x and y in the equation shows a proportional relationship?
1. y=5(x+3)
2. y = 5x + 3
3. y=x−2
4. y = 3x
Answers
Answer:
4. y = 3x
Step-by-step explanation:
A proportional relationship is one in which the ratio of two variables is always constant. This is also known as direct proportion.
Out of the given options, the equation that shows a proportional relationship is:
4. y = 3x
In this equation, the ratio of y to x (y/x) is always 3, so the relationship between y and x is proportional. As x increases, y also increases at a constant rate, and as x decreases, y decreases at a constant rate. This type of relationship is often represented by the equation y = kx, where k is the constant of proportionality.
