Given :
A store received 300 containers of milk to be sold by February 1. Each container cost the store $0.79 and sold for $1.55. The store signed a contract with the distributor in which the distributor agreed to a $0.50 refund for every container not sold by February 1.The formula of profit is given below:
Profit = Revenue - Expenses --- (1)
So, first determine the total cost of the 300 containers.
Total Cost = 300 [tex]\times[/tex] 0.79
= $237
Now, determine the revenue for the 270 sold containers.
Revenue = 270 [tex]\times[/tex] 1.55
= $418.5
Now, the determine the revenue for the 30 unsold containers.
Revenue = 30 [tex]\times[/tex] 0.50
= $15
So, the total revenue is given by:
Total Revenue = 418.5 + 15
= $433.5
Now, substitute the known terms in the equation (1).
Profit = 433.5 - 237
= $196.5
So, the total profit did the store make is $196.5.

To estimate the value of e^−0.01 using linear approximation or differentials, we can use the fact that the derivative of e^x is e^x. Specifically, we can linearize the function at a point close to x = -0.01 and use the linear equation to estimate the value of e^−0.01.
Explanation:To estimate the value of e^−0.01 using linear approximation or differentials, we can use the fact that the derivative of e^x is e^x.
Specifically, we can linearize the function at a point close to x = -0.01 and use the linear equation to estimate the value of e^−0.01.
Let's use the point x = 0 as our approximation point.
The linear equation is given by y = f'(a)(x - a) + f(a), where y represents the value of e^x, f'(a) represents the derivative of e^a at x = a, and f(a) represents the value of e^a at x = a.
Since the derivative of e^x is simply e^x, we have f'(0) = e^0 = 1.
Plugging in the values, we get y = 1(x - 0) + e^0 = x + 1. Therefore, substituting x = -0.01 into the equation, we estimate that e^−0.01 ≈ -0.01 + 1 = 0.99.

Given the figure below, find the values of x and z .
There is a picture below to see it clearly.
Two angles whose sum is 180° are called supplementary angles. The value of x is 10, while the value of z is 96.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
The measure of ∠Z will be equal to 96° because ∠AOB and ∠COD are vertically opposite angles.
The sum of the measure of ∠AOB and ∠BOC will be equal to 180°, since both lie on the same line, therefore,
∠AOB + ∠BOC = 180°
96° + (14x - 56)° = 180°
14x - 56 = 180 - 96
14x = 140
x = 10°
Hence, the value of x is 10, while the value of z is 96.

Final answer:
The monthly payment is $168.35, and the interest amount to pay is $360.45.
Explanation:
Simple interest is calculated on the principal amount at a given rate over a specific time period. The formula for simple interest is SI = PRT / 100, where P represents the principal, R denotes the rate, and T signifies the time in years. In this scenario, the principal is $2670, the time is 18 months (or 1.5 years), and the rate is 9%. Substituting these values into the formula, we find that the simple interest amounts to $360.45. Adding this interest to the principal, the total amount to pay becomes $3030.45. Finally, by dividing this total by the time in years (18 months or 1.5 years), we determine that the monthly payment is $168.35. Therefore, the monthly payment is $168.35, and the interest amount to pay is $360.45.
find the degree of the polynomial and determine whether it is a monomial, binomial,trinomial, or none of these 5x+7
Final answer:
The degree of the polynomial 5x+7 is 1; it has two terms, 5x and 7, and therefore, it is classified as a binomial.
Explanation:
To find the degree of the polynomial 5x+7 and determine whether it is a monomial, binomial, or trinomial, we first examine the terms of the polynomial. This polynomial has two terms, which are separated by a plus sign. The first term is 5x and the second term is 7. The degree of a polynomial is the highest power of the variable x that appears in the polynomial. In the term 5x, x is to the first power (since x is equivalent to x^1), and in the term 7, x is to the zero power (since any number to the zero power is 1, and the term does not contain x). Therefore, the degree of the polynomial is 1, which is the degree of the term 5x.
Since 5x+7 consists of two terms, it is known as a binomial. A monomial would have only one term, a binomial has two terms, and a trinomial has three terms. Therefore, the polynomial 5x+7 is a binomial of degree 1.

Two cars leave towns 300 kilometers apart at the same time and travel toward each other. One car's rate is 16 kilometers per hour more than the other's. If they meet in 2 hours, what is the rate of the faster car?
To find the rate of the faster car, set the speed of the slower car as 'x' km/h and the speed of the faster car as 'x + 16' km/h. Since they meet in 2 hours, and the total distance is 300 km, the equation is 2x + 2(x + 16) = 300. The faster car's speed is found to be 83 km/h.
Explanation:The question involves solving for the rate of the faster car when two cars travel towards each other from a distance of 300 kilometers apart and meet after 2 hours. We'll designate the speed of the slower car as 'x' km/h, which implies the speed of the faster car is 'x + 16' km/h. Since they meet in 2 hours, the total distance covered by both cars together is 300 kilometers.
Using the formula for distance (distance = rate × time), we can set up an equation:
2x + 2(x + 16) = 300
Simplifying this equation:
2x + 2x + 32 = 300
4x = 268
x = 67
The speed of the slower car is 67 km/h, and therefore, the rate of the faster car must be 67 + 16, which is 83 km/h.

A room has an area of 456 square feet. One dimension is 5 feet more than the other. Find the dimensions of the room.
Dimensions of the room with area of 456 square feet is 19 feet by 24 feet.
To solve for the dimensions of a room where the area is 456 square feet and one dimension is 5 feet more than the other, we can set up the following equations:
Let the width be x feet.
Then the length will be (x + 5) feet.
The area of a rectangle is given by the multiplication of its length and width, so the equation to represent the area is x(x + 5) = 456.
Expanding this, we get x2 + 5x - 456 = 0.
This is a quadratic equation which can be factored or solved using the quadratic formula. Factoring gives us (x - 19)(x + 24) = 0.
Since a room cannot have a negative dimension, we take the positive value of x, which is 19 feet.
Therefore, the width of the room is 19 feet, and the length is 19 + 5 = 24 feet.
Identify a pattern in the given list of numbers.Then use this pattern to find the next number.
1,4,1,20,1,100,1
The number sequence alternates between 1 and multiples of 5. The pattern of the multiples of 5 increases by a factor of 5 each time, next number in the sequence being 500.
The sequence shown is 1, 4, 1, 20, 1, 100, 1.
To find the next number in this sequence, we can observe that the sequence of numbers (not including the 1's) is increasing by a factor of 5 each time =(4, 20, 100, ...).
Since 100 =5*20, to find the next number after the last 1, we need to multiply 100 * 5.
So, the next number after the last 1 would be 100* 5 = 500.

The first term of a geometric sequence is 15 and the second term is 6. Find the fourth term.
To find the fourth term of a geometric sequence with a first term of 15 and a second term of 6, we first calculate the common ratio (r = 2/5), and then successively multiply by the common ratio to find subsequent terms. The fourth term is determined to be 24/25.
The question involves finding the fourth term of a geometric sequence where the first term (a₁) is 15, and the second term (a₂) is 6. In any geometric sequence, each term is found by multiplying the previous term by a common ratio (r). Thus, we can find r by dividing the second term by the first term: r = a₂ / a₁ = 6 / 15 = 2 / 5.
Now that we have the common ratio, we can find the third term by multiplying the second term by the ratio: a₃ = a₂ × r = 6 × 2 / 5 = 12 / 5. Finally, we find the fourth term by multiplying the third term by the ratio: a₄ = a₃ × r = (12 / 5) × (2 / 5) = 24 / 25.
Therefore, the fourth term of the geometric sequence is 24/25.
