To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
What is the average?Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
69 seconds.58 seconds.45 seconds.120 seconds.76 seconds.The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Answer:
24 bracelets can be made from given beads.
● Explanation -To make similar bracelets using all the beads, we have to find the highest common factor of no of beads.Now, Factors of 72 => 1, 2, 3, 4, 6, 8 , 9, 12, 18, 24, 36, 72Factors of 192 => 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192Factors of 120 => 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120HCF => 24Observing this data, HCF of 72, 192 & 120 will be 24.Therefore, total 24 bracelets can be made from given beads.* Each bracelet will have 3 red, 8 blue and 5 white beads.
Select the correct answer. Brianna begins the construction of square EGFH inscribed in circle C by drawing GH, a diameter of the circle that is also a diagonal of the square. Next, she plans to use a compass to construct a perpendicular bisector of GH and mark points E and F at the intersections of the arcs she used to find the bisector. What error, if any, is Brianna making? A. She is not making any errors. B. She should name the diameter she first drew EG and name the new segment FH. C. She should use the compass to find the perpendicular bisector of GC instead of GH. D. She should define points E and F as where the perpendicular bisector of GH intersects the circle. Reset Next
Answer:
B. "She should name the diameter she first drew EG and name the new segment FH."

H(n)=n+2
g(n) = 2n + 1
Find h(n) − g(n)
Answer:
-n + 1
Step-by-step explanation:
(n + 2) - (2n + 1)
n + 2 - 2n - 1
-n + 1
Answer:
[tex] \sf \: -n + 1 [/tex]
Step-by-step explanation:
Given information,
→ h(n) = n + 2
→ g(n) = 2n + 1
Now we have to,
→ find the value of h(n) - g(n).
Then required value will be,
→ h(n) - g(n)
→ (n + 2) - (2n + 1)
→ n + 2 - 2n - 1
→ (n - 2n) + (2 - 1)
→ (-n) + (1)
→ -n + 1
Hence, the value is -n + 1.

If the total surface area of a cube is 96cm², find its volume
======================================================
Explanation:
Let's find the side length of the cube based on the given surface area.
SA = 6s^2
96 = 6s^2
6s^2 = 96
s^2 = 96/6
s^2 = 16
s = sqrt(16)
s = 4
The cube has side length 4 cm.
Now calculate the total volume.
V = s^3
V = 4^3
V = 4*4*4
V = 64 cubic cm.
-------------------
Extra info:
The unit "cubic cm" can be abbreviated to "cc". So whenever you hear something from a medical tv show "get me 10 cc's of XYZ", that's what they're referring to. Of course the "10" might be some other realistic value, it's just an example.
1 cc = 1 milliliter

1. Two containers are being filled with water. One begins with 10 gallons of water and is filled at a rate of 2.5 gallons per minute. The other begins with 24 gallons and is filed at 2.25 gallons per
minute.
Part A: Write an equation that represents the amount of water w, in gallons, with respect to time t, in minutes, for each container
Part B: Solve the system of equations. Show your work
Part C: How long would it take for both of the containers to have the same amount of water? How much water would be in each container?
Answer: PART A:
w-3.5 t=8
w-3.25t=24
PART B:
t=64
and w= 232
PART C:
It will take 64 minutes for both of the containers to have the same amount of water.
The amount of water in each container is:
232 gallons.
Step-by-step explanation:
PART A:
Let the water is filling in 't' minutes.
and 'w' denotes the amount of water in the container.
for container 1:
One begins with 8 gallons of water and is filled at a rate of 3.5 gallons per minute.
The equation is given by:
or
for container 2:
The other begins with 24 gallons and is filled at 3.25 gallons per minute.
The equation is given by:
or
PART B:
on solving equation (1) and equation (2) by method of elimination we get:
subtract equation (2) by equation (1) to obtain:
t=64
and putting the value of t in equation (1) to obtain:
w= 232
PART C:
Hence it will take 64 minutes for both of the containers to have the same amount of water.
The amount of water in each container is:
232 gallons.

What is an equation of the line that passes through the points (8,0) and (3,-5)?
Answer:
y = x - 8
Step-by-step explanation:
You want an equation for the line through the points (8, 0) and (3, -5).
SlopeThe slope of the line can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (-5 -0)/(3 -8) = -5/-5 = 1
InterceptThe y-intercept can be found from the equation ...
b = y1 -m(x1)
b = 0 -1(8) = -8
Slope-intercept equationThe slope-intercept equation of the line is ...
y = mx +b
y = 1·x +(-8)
y = x -8 . . . . . an equation for the line

a cone has a volume of 150.72 cubic millimeters and a height of 9 millimeters what is the radius
The volume of a cone is the amount of space in the cone
The radius of the cone is 4.00 millimeters
How to determine the radiusThe given parameters are:
Volume = 150.72 cubic mL
Height = 9 mL
The volume of a cone is calculated as:
[tex]V = \frac 13 \pi r^2h[/tex]
So, we have:
[tex]150.72 = \frac 13 \pi * r^2 * 9[/tex]
Divide
[tex]150.72 = \pi * r^2 * 3[/tex]
Divide both sides by 3
[tex]50.24 = \pi * r^2[/tex]
Rewrite the equation
[tex]50.24 = \frac{22}{7} * r^2[/tex]
Solve for r^2
[tex]r^2 = 50.24 * \frac{7}{22}[/tex]
Solve for r
[tex]r = 4.00[/tex]
Hence, the radius of the cone is 4.00 millimeters

Step-by-step explanation:
so the middle rectangle part first
15x10=150
then there's triangles so i'm gonna skip the divided by 2 part.
5x4=20
150+20=170
Solution:
Note that:
Surface area = 2(Area of triangle) + 3(Area of rectangle)Finding the area of triangle:
Area of triangle = 1/2 x 4 x 5=> Area of triangle = 1/2 x 20Area of triangle = 10 cm²Finding the area of rectangle:
Area of rectangle = 5 x 10=> Area of rectangle = 50 cm²Using the formula of surface area:
Surface area = 2(Area of triangle) + 3(Area of rectangle)=> Surface area = 2(10) + 3(50)=> Surface area = 20 + 150=> Surface area = 170 cm²The sum of two numbers is 75. Their difference is 25. What are the two numbers?

Answer:
50 and 25
Step-by-step explanation:
y+x=75
y-x=25
y+y=yx and x-x eliminate itself
so now we have the operation 2y= 50, I got the 50 from substrating 25 from 75
now found the value of y, 50/2=25
so y=25

When a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial. The factors of x³-5x+6 are (x+5)(x-2)(x-3).
What is the Remainder theorem?According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.
Since f(–5) = 0, therefore, (x+5) is a factor of the polynomial f(x).
