At the bookstore, Tim bought a magazine for $4, and five
books that all cost the same amount. He spent a total of
$129. Which equation expresses how much each book
cost?
A.x= 129-4
B.5x - 4 = 129
C.5x + 4 = 129
D.4x + 5 = 129
The correct equation that expresses how much each book cost is C.5x + 4 = 129, where x represents the price of one book.
Explanation:The student asked which equation expresses how much each book cost if Tim bought a magazine for $4 and five books that all cost the same amount, spending a total of $129. The correct equation would account for the magazine's cost and the total cost of the five books. The equation that represents this scenario is C.5x + 4 = 129, where x represents the cost of one book, 5x represents the total cost of the five books, and 4 is the cost of the magazine. To find the cost of each book, you need to subtract the magazine's cost from the total and then divide by the number of books. The equation 5x + 4 = 129 does this correctly because when we subtract 4 (the cost of the magazine) from 129 (total amount spent), and then divide that result by 5, we find the cost of a single book.

for the Equtionb 1.75n=7,what is the value of n?
To solve the equation 1.75n = 7, divide both sides by 1.75 to isolate n, which simplifies to n = 4. Therefore, the value of n is 4.
Explanation:To solve the equation 1.75n = 7 for the value of n, you need to isolate n. This can be accomplished by dividing both sides of the equation by 1.75, the coefficient of n.
Here are the steps:
Divide both sides of the equation by 1.75:1.75n / 1.75 = 7 / 1.75Simplify both sides:n = 4The result is n = 4. Therefore, the value of n that satisfies the equation is 4.The hypotenuse of a right triangle is 4 feet

A square pyramid has a height of 25 ft and each side of the base has a length of 15 ft.
If a model of the square pyramid is scaled down by a factor of , what is the surface area of the model?
To determine the surface area of a model pyramid that has been scaled down, we must first compute the area of the original pyramid, and then multiply that area by the square of the scale factor.
Explanation:To find the surface area of a square pyramid we first calculate the area of the base which is side squared (152 = 225 sq ft), and then calculate the area of the four triangular faces. For the latter we can use the formula 0.5 x base x height, where base is the side of the pyramid (15 ft) and height is the slant height. The slant height can be calculated using Pythagoras' theorem which constitutes of half of the base and the height of the pyramid, this will give us the slant height, which then can be used in the surface area formula.
Next, if the pyramid is scaled down by a factor of 0.5, both lengths and areas are reduced by that factor. Hence, multiply the original area by 0.52 = 0.25 to find the surface area of the model pyramid.

Y=-6.25x+1200
Answer:
negative,1800 feet , y=16.25x+1,800
Step-by-step explanation:
The correlation, y-intercept, and equivalent representations of given points all depend on the data's plot on the graph. The correlation is classified as positive, negative, or none based on the scatter pattern of points. The y-intercept is where the line intersects the y-axis, and it could be any of the provided options. The equation representing the line of best fit depends on the slope (gradient) and y-intercept of the line.
Explanation:Without the actual data points, it's hard to definitively answer, but I'll provide some general guidance. The correlation of data points can be categorized as positive, negative, or none depending on how they are scattered on the graph. A positive correlation means as one variable increases, the other increases too, while a negative correlation means as one variable increases, the other decreases. When there's no pattern to the points, the correlation is none.
In terms of y-intercept, it's the point where the line crosses the y-axis. If we assume y-intercept as one of the options provided, e.g. 800 feet, 1200 feet, 1800 feet, and 2200 feet, it depends on how the line fits on the graph.
Similarly, the equivalent representation like Y=800 or Y=-17.5x+2200, Y=-16.25x+1800, or Y=-6.25x+1200 is dependent on the actual pattern of the data points. These representations are equations of straight lines where '-17.5', '-16.25', and '-6.25' represent the slope and '2200', '1800', '1200' respectively are the y-intercepts.

The number of birds in a forest is decreasing by 3% every year. In 2000 there were 5,400 birds. Write an equation that represents the number, y, of birds x years after 2000. How many birds will there be in 2025? Round your answer to the nearest whole number.
Answer:
Step-by-step explanation:
This is a Compound interest problem with a decreasing rate. It is given by the formula:
A = P(1 +/- R)^T
Where A = amount after time T
P = principal or initial amount
R = rate of increase or decrease
T = time elapsed
There's +/- because + is used in the case when the amount is increasing at a particular rate and - is used whe the amiunt is decreasing.
In 2000 there were 5,400 birds and the number of birds is decreasing by 3% (0.03) every year.
The number of birds, y, that will be there x years after 2000 will be:
y = 5400( 1 - 0.03)ˣ
2025 is 25 years ahead of 2000, so x = 25
Therefore, the number of birds in 2025 will be:
y = 5400(1 - 0.03)^25
y = 5400(0.97)^25
y = 5400 * 0.467
y = 2522 birds
There will be 2522 birds in 2025.
The equation to represent the number of birds after x years is y = 5,400(1 - 0.03)^x. To find the number of birds in 2025, we use x = 25 in the equation to get y ≈ 3,295 birds.
Explanation:To write an equation that represents the number, y, of birds x years after 2000 with a yearly decrease of 3%, we use the formula for exponential decay, which is y = a(1 - r)^x. Here, a is the initial amount, r is the rate of decrease, and x is the number of years since 2000.
In this case, the initial number of birds in 2000 was 5,400, so a = 5,400, and the rate of decrease is 3%, meaning r = 0.03. The equation becomes y = 5,400(1 - 0.03)^x.
To find out the number of birds in 2025, we calculate x as the number of years from 2000 to 2025, which is 25 years. Thus, the calculation results in y = 5,400(1 - 0.03)^25. After solving, we round the result to the nearest whole number.
Performing the calculation, y ≈ 3,295 birds.
A data scientist tried to many cups of coffee she drink every day at work over the course of the year. She used the data to build a probability distribution where the random variable C represents the number of cups of coffee she drank on a given day. Find the missing probability for someone who has two or more cups of coffee.
To find the missing probability for consuming two or more cups of coffee in the data scientist's distribution, subtract the sum of the probabilities of all other events from 1, ensuring that all probabilities in the distribution meet the criteria of summing to 1 and each being between 0 and 1.
Explanation:The question pertains to constructing a probability distribution for a data scientist's daily coffee consumption at work. The random variable C stands for the number of cups of coffee she drinks on a given day. To calculate the missing probability for someone who has two or more cups of coffee, one must know the individual probabilities of all other events (0, 1, 2, etc., cups of coffee). The sum of all these probabilities must equal 1, since that represents the certain event that some outcome in the distribution will occur. To find the missing probability, one would subtract the sum of the probabilities for 0 and 1 cups (if those are the only other events) from 1.
For example, if the probability of drinking 0 cups is 0.1 and the probability of 1 cup is 0.3, then the probability of drinking two or more cups would be 1 - (0.1 + 0.3) = 0.6. Important characteristics of a discrete probability distribution include that the sum of probabilities is 1 and that each individual probability is between 0 and 1, inclusive.

A hot air balloon went from an elevation of 5,275 feet to an elevation of 3,128 feet in
38 minutes. What was its rate of descent?
The rate of the descent was_____ feet per minute.
Answer:
0.942 ft/s
Step-by-step explanation:
The rate of descent is the rate at which the hot air balloon is descending, that is, how fast it is descending.
We calculate this by finding how far it has moved and then dividing it by the time it took it to descend.
It moved from 5275 ft to 3128 ft. The displacement is:
5275 - 3128 = 2147 ft
The time taken is 38 minutes. In seconds, it is:
38 * 60 = 2280 seconds.
Therefore, the rate of descent is:
2147 / 2280 = 0.942 ft/s
