Answer:
639 students attend the highschool
Step-by-step explanation:
Find one-ninth of the students
Since 142 students is two-ninths of students, we would divide
1) 142/2=71
71 students is only one ninth of the students, we need to find 9/9 of students
2) 71*9 = 639
639 students attend school
There is a total of 639 students in the school.
What is a fraction?If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
Let's say the number of students in the school is x
Then,
Since 2/9 of it are in the school band
So,
(2/9) x = 142
x = 639
Hence "There is a total of 639 students in the school".

How is the Pythagorean theorem related to the distance formula?Explain.
Answer:
If you plot 2 points on a graph right, you can form a triangle between the 2 points. You can determine the legs's sizes using the coordinates of the points. Pythagorean theorem is then used to find the hypotenuse, which IS the distance from one point to the other. Hope that helps.
Step-by-step explanation:
Answer:
Sample Response: Both formulas can be used to find the distance between two points on the coordinate plane. The vertical leg of the right triangle represents the difference in the y values of the two points. The

(8b + 8) + (7m – 2) + (4n + 4)
(8b + 8) + (7m - 2) + (4n + 4) =
(Simplify your answer.)
Answer:
8b + 7m + 4n = -10
Step-by-step explanation:
(8b + 8) + (7m – 2) + (4n + 4)
First thing to do is to try to open the brackets, so we have
8b + 8 + 7m - 2 + 4n + 4 =
Next, we collect like terms, so that we have
8b + 7m + 4n + 8 - 2 + 4 =
8b + 7m + 4n + 10 =
And rearranging, we have that
8b + 7m + 4n = -10

A. -6x2 - x-7
B. 6x2 – x+7
C. 12x2 - x-7
D. -6x2 – 3x-7
Answer:
A
Step-by-step explanation:
We have the two functions:
[tex]f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\[/tex]
And we want to find:
[tex](f-g)(x)[/tex]

Answer: 9/10 of the book.
Step-by-step explanation:
1. Convert all of the fractions to have a common denominator. 6, 5, and 3 are all multiples of 30, so we can convert the fractions to 30ths.
1/6 = 5/30
2/5 = 12/30
1/3 = 10/30
2. Add the fractions together to find the whole amount of the book Joyce has read.
5/30 + 12/30 + 10/30 = 27/30
3. Simplify
27/30 -> 9/10
Step-by-step explanation:
1/6 + 2/5 +1/3=
nominator × with the other fraction denominator+ second fraction nominator × with first denominator / denominator ×denominator =

What 3 consecutive numbers if the sum is 15333
Answer:
[tex]5110, 5111, 5112[/tex]
Step-by-step explanation:
Let [tex]x=[/tex] first consecutive number
[tex]x + (x+1)+(x+2) = 15333[/tex] ([tex]x[/tex] is the first number, [tex]x+1[/tex] would be the second consecutive number of the sequence, and [tex]x+2[/tex] would be the third)
[tex]3x + 3 = 15333[/tex]
[tex]3x = 15330[/tex]
[tex]x = 5110[/tex]
[tex]x+1 = 5110+1[/tex]
[tex]= 5111[/tex]
[tex]x+2 = 5110 + 2[/tex]
[tex]= 5112[/tex]
[tex]\therefore[/tex] the consecutive numbers that sum up to [tex]15333[/tex] are [tex]5110, 5111,[/tex] and [tex]5112[/tex]

The price of Stock A at 9 A.M. Was $12.53. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $13.28. It begins to decrease at the rate of $0.09 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
1.8571428 hours
Step-by-step explanation:
Given that :
Price of stock A at 9 am = $12.53
Rate of increase = $0.12 per hour
Price of stock B at noon = $13.28
Rate of Decrease = $0.09 per hour
Let number of hours = x
Price of stock A at noon :12.53 + 0.12(3) = 12.89
12.89 + 0.12x = 13.28 - 0.09x
0.12x + 0.09x = 13.28 - 12.89
0.21x = 0.39
x = 0.39 / 0.21
x = 1.8571428
Hence the prices of the stock will be the at about 1.857 hours
Evaluate the step function for the given input values.

g(x) =
3, 25x< 4
5, x 24
9(2) =
g(-2) =
g(5) =
Answer:
I would, but the way this is set up is VERY confusing. sorry. maybe try to fix it after copying and pasting to make sure it makes sense.
The evaluated values of the step function for the given input values are as g(-2) = -4, g(2) = 3, and g(5) = 5.
To evaluate the step function g(x) for the given input values, we need to follow the conditions specified for each interval.
Given the step function:
g(x) =
-4, x < -1
-1, -1 ≤ x < 2
3, 2 ≤ x < 4
5, x ≥ 4
Let's evaluate the step function for each input:
g(-2):
Since -2 is less than -1, the condition for the first interval is satisfied. Therefore, g(-2) = -4.
g(2):
Since 2 is less than or equal to 4, the condition for the second interval is satisfied. Therefore, g(2) = 3.
g(5):
Since 5 is greater than or equal to 4, the condition for the last interval is satisfied. Therefore, g(5) = 5.
Hence, we have:
g(-2) = -4
g(2) = 3
g(5) = 5
