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.

The 225 students who passed all of their classes on the last report card will attend a one-hour Friday Fun-Day sponsored by the Parent-Teacher
Organization (PTO). A variety of activities and snacks will be provided and students will receive one prize. A random survey of 50 students was
conducted to determine how many of each prize should be purchased for the Friday Fun-Day. The results of the survey are shown.
• 28 students want a slime kit.
• 12 students want a basketball.
• 6 students want a jewelry bead kit.
• 4 students want an artist sketch pad and pencil set.
Problem
Based on the survey results, which of these is NOT a valid prediction of the prizes wanted by the 225 students?
A There are 126 students who want a slime kit.
B There are 36 fewer students that want an artist sketch pad and pencil set than a basketball.
C There are 71 students who want either a basketball or a jewelry bead kit.
D There are 27 more students who want a slime kit than all the other prizes combined.
Answer:
C. is incorrect.
Step-by-step explanation:
Calculate the percentages for each prize desired by the 50 students responding in the sample survey. See the attached image for this calculation. Multiply these percentages times the total student body of 225 students to determine the likely selection for each prize (on the attachment).

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).

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

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. 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

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.
The sum of two numbers is 75. Their difference is 25. What are the two numbers?
Show all work
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
now plug the number in
25+x=75
75-25=50
so x= 50
Which ratio best defines relative frequency? Number of nonfavorable outcomes:Number of possible outcomes Number of possible outcomes:Number of nonfavorable outcomes Total number of times an experiment is performed:Number of times an event occurs Number of times an event occurs:Total number of times an experiment is performed.
The ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.
What is relative frequency?Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.
The relative frequency can be given as,
[tex]f_r=\dfrac{f}{n}[/tex]
Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.
The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.
Now, the ratio has to be find out which best defines relative frequency. Lets check options,
Number of non-favorable outcomes:Number of possible outcomes-Here, the non-favorable outcomes is asked but for the relative frequency the favorable outcomes is considered. Number of possible outcomes:Number of non-favorable outcomes-The number of total outcomes is considered for a relative frequency. Total number of times an experiment is performed:Number of times an event occurs-This ratio is inverse as the ratio of relative frequency.Number of times an event occurs:Total number of times an experiment is performed-This is the correct option, as it justify the definition of the relative frequency.Hence, the ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.
