Based on the graph, which of the following statements is true?
A.
The number of pumpkins depends on the total price.
B.
The total price depends on the number of crates.
C.
The number of crates depends on the total price.
D.
The total price depends on the number of pumpkins
Answers
Answer:
The total price depends on the number of crates.
Step-by-step explanation:
Without seeing the graph, we can't provide a definitive answer. Generally, in such situations, total price would likely depend on the quantity of goods (pumpkins or crates) purchased (Options D and B).
Explanation:To answer this question, we'd need to closely examine the given graph. However, generally, in a graph showcasing a transaction, the total price depends on the quantity of goods, such as pumpkins or crates, purchased. Hence without explicit information from the graph at hand, option D. 'The total price depends on the number of pumpkins', and option B. 'The total price depends on the number of crates' could potentially be accurate. But we cannot determine definitively without further information.

to get this answer, you first need to consider the 108 books. they are getting split to 2 classes, so divide and youll get 54. from this, EACH class has 18 students, so if you divide, each student gets at most 1
if i got the each part wrong, it would be 3
hope this helps!!!
Each student will receive 3 book covers when 108 book covers are equally distributed among 36 students from two sixth-grade classes.
The question asks us to figure out how many book covers each student will receive if 108 book covers are distributed equally among students in two sixth-grade classes, with each class having 18 students.
First, calculate the total number of students by multiplying the number of classes by the number of students in each class: 2 classes * 18 students/class = 36 students.Then, divide the total number of book covers by the total number of students: 108 book covers / 36 students = 3 book covers per student.As a result, each student will receive 3 book covers.

Answers
Answer:
x-intercept (12.5, 0)y-intercept (0, -5)Step-by-step explanation:
The slope of the line is ...
... (change in y)/(change in x) = (-3 -(-5))/(5 - 0) = 2/5
The y-intercept is given: (0, -5).
The slope-intercept form of the equation can be written from this information as ...
... y = (2/5)x - 5
Solving this for y=0 (to find the x-intercept), we have
... 0 = (2/5)x - 5
... 5 = (2/5)x
... 5·(5/2) = x = 12.5
So, the x-intercept is 12.5, and the y-intercept (given) is -5.

Simplify the expression. 12x^-6 y^10 times 3x^7 y
Answers
We need to simplify the expression:
[tex]12x^{-6}y^{10} \times (3x^{7}y)[/tex]
Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:
Now,
[tex]12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)[/tex]
On simplifying the above expression we get:
[tex]36\times x^{(-6+7)}\times y^{(10+1)}[/tex]
[tex]=36 \times x^{1}\times y^{11}[/tex]
[tex]=36 \times x \times y^{11}[/tex]

an inch is 1/12 of a foot how much has a angelfish grown in a feet
Answers
To find out how much an angelfish has grown in feet, divide the number of inches by 12, since there are 12 inches in a foot. As an example, if an angelfish has grown 6 inches, it would be 6 inches / 12, equaling 0.5 feet.
Explanation:To convert a measurement from inches to feet, we use the fact that one foot is equal to 12 inches. For example, if an angelfish has grown 6 inches, we divide the number of inches by 12 to find the growth in feet:
Find the growth in inches (for example, 6 inches).Use the conversion factor, which is 1 foot = 12 inches.Divide the growth in inches by 12 to get the growth in feet. For 6 inches: 6 inches / 12 inches per foot = 0.5 feet.The angelfish has grown 0.5 feet.
Similarly, let’s convert 374 inches to feet as another example of going from a smaller unit to a larger unit:
Take the given number of inches and divide by 12 since there are 12 inches in a foot.374 inches divided by 12 equals 31(1/6) feet.An analog clock loses 2 minutes every 3 hours. What is the shortest interval of time after which the clock will show the correct time?

the probability is a ratio of number of relevant outcomes and total number of possible cases.
In this scenario, the relevant outcomes are
4, 5, 10 (and their count is 3)
and the total number of possible outcomes:
12
so the probability is
3/12 = 1/4
the answer is 3/12 cause when you divied 12 by 4 you will get 3 and we know that there is 12 faces on the cube so that gives you the ratio 3/12.

At a school concert the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others. How long is the concert ?
Answers
Answer:
Total time of the concert = 59.5 min = 59 minute 30 seconds
Explanation:
At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.
Total length of 8 songs = 4.25*8 = 34 min
Length of 3 songs = 2*4.25 = 8.5 min
Total length of 3 songs = 3* 8.5 = 25.5 min
Total time of the concert = 34 + 25.5 = 59.5 min = 59 minute 30 seconds
The concert is 59.5 minutes long: 8 shorter songs at 4.25 min each and 3 longer songs at 8.5 min each.
To find the total duration of the concert, we first calculate the duration of the 8 shorter songs and then the longer ones.
1. Shorter songs:
Duration of each shorter song = 4.25 minutes
Total duration of 8 shorter songs = 8 × 4.25 = 34 minutes
2. Longer songs:
Each longer song is twice as long as the shorter ones, so its duration is 2 × 4.25 = 8.5 minutes
Total duration of 3 longer songs = 3 × 8.5 = 25.5 minutes
Now, add the durations of both types of songs to find the total duration of the concert:
Total duration = Duration of shorter songs + Duration of longer songs
Total duration = 34 minutes + 25.5 minutes = 59.5 minutes
So, the concert is 59.5 minutes long.

The product of (3 + 2i) and a complex number is (17 + 7i).
The complex number is ?
Answers
The product of (3 + 2i) and a complex number is (17 + 7i)
The product of (3 + 2i) and a complex number is (17 + 7i).
Let the complex number be a + ib
Product means we multiply
So (3+2i) * (a + ib) = (17+7i)
WE need to find a+ ib
Divie by 3 + 2i on both sides
a + ib = (17+7i) / (3+2i)
To divide multiply by the conjugate (3-2i)
[tex]a + ib = (\frac{ 17+7i)*(3-2i)}{(3+2i)(3-2i)}[/tex]
[tex]a + ib = (\frac{(17*3+7*2)+(7*3-17*2)i}{3^2-2^2}[/tex]
[tex]a + ib = (\frac{(65)+(-13)i}{13}[/tex]
[tex]a+ib = \frac{65}{13} - \frac{13}{13}[/tex]
a+ib = 5 - i
The required complex number is 5 - i
Answer:
37+55i
Step-by-step explanation:
The product of (3 + 2i) and a complex number is (17 + 7i) is expressed as shown below:
(3+2i)(17+7i)
Expanding the bracket,
= 51+21i+34i+14i²
= 51+55i+14i²
Note that in complex numbers i² = -1
Substituting this into the result, we have:
= 51+55i+14(-1)
= 51+55i-14
= 37+55i
The product of both complex number is 37+55i
