Determine which integer will make the inequality 2(n + 2) < 5(n − 1) true.
S:{10}
S:{3}
S:{2}
S:{0}
Answer:
10
Step-by-step explanation:
if you replace n with 10 you will get
2(10+2)<5(10-1)
2(12)<5(9)
24<45
which is a true statement if you replace n with any other number you will get a incorrect statement and if you replace n with 3 though they are equal it's not a ≤ it's only <
7. The volume of a cylinder is represented by the formula V = r² h.
Find each missing height and show your reasoning.
volume (cubic inches) radius (inches) height (inches)
96. 4
31.25. 2.5
V. r
Based on the calculations, each missing height of this cylinder is; 6 and 5 inches.
How to calculate the volume of a cylinder?Mathematically, the volume of a cylinder can be calculated by using this formula:
V = πr²h
Where:
V is the volume of a cylinder. h is the height of a cylinder. r is the radius of a cylinder.
Now h the subject of formula, we have:
h = V/πr²
When V = 96π and r = 4, the volume of this cylinder is;
h = V/πr²
h = 96π/π(4)²
h = 96/16
Height, h = 6.
When V = 31.25π and r = 2.5, then the volume of this cylinder is;
h = V/πr²
h = 31.25π/π(2.5)²
h = 31.25/6.25
Height, h = 5.

Mary is four years older than Sue. If the sum of their ages is 16, how old are Mary and Sue?
Answer: Mary 10 Sue 6
Step-by-step explanation:
Answer:
Sue is 6 and Mary is 10
Step-by-step explanation:
let Sue's age be x then Mary is x + 4 and the sum of their ages is
x + x + 4 = 16
2x + 4 = 16 ( subtract 4 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
x + 4 = 6 + 4 = 10
then Mary is 10 and Sue is 6
Directions: Determine whether each equation represents a direct variation. If yes, identify the
constant of variation.
Y - 6 =2(x-3)
Answer:
Yes, this equation represents a direct variation equation
constant of variation = 2
=========================================================
Explanation:
Let's solve for y
y - 6 = 2(x-3)
y - 6 = 2x - 6
y - 6+6 = 2x - 6+6
y + 0 = 2x + 0
y = 2x
The equation is in the form y = kx which fits a direct variation equation. The constant of variation is k = 2.

Mike Lasueze is a salesperson in the appliance department at Wicklow Appliance Inc. He is guaranteed a minimum salary of $220 per week or 5.5% of his total sales, whichever is greater. What is his gross pay for a week in which his total sales were $8,400?
For a sale of $8400 made his gross pay is $373.21
In this question, we have been given Mike Lasueze is guaranteed a minimum salary of $220 per week or 5.5 percent of his total sales, whichever is greater.
We need to find his gross pay for a week in which his total sales were $8,400
weekly pay = $220
commission = 5.5% of sales
= 0.055 of sales
Let m be the total sale and his gross pay be represented by y.
So, we get an equation for the total/gross pay:
y = 0.055x + 220
Required is the gross pay y for x = 8400
y = 0.055(8400) + 220
y = 682
Therefore, for a sale of $8400 made his gross pay is $373.21

A group of 23 friends are at the theater but can't agree on which movie to see. some of the group decides to see lightyear which is playing for $4 per ticket and the rest of the group decides to see jurassic park which is playing for $9 per ticket. altogether the group spends $172, how many of them saw lightyear?
The number of people who watched light year are 7.
Let x= number of friends that watches light year
and y= number of friends that watches jurassic park.
Let the equations be
All together total cost => 4x+9y=172 ------> 1
And total number of people=> x + y=23 ------> 2
By multiplying both equations by 1 and 4 respectively we can get,
By Solving above two equations we get, x=7 and y=16
As X represents number of friends that watches light year, the answer is 7
Therefore, number of people that watches light year will be 7.

imagine that a researcher is interested in whether residents in his local area have higher levels of well-being than the national average. what would be an appropriate alternate hypothesis for a one-tailed or directional z-test for this test? group of answer choices
The alternate hypothesis for the directional z-test is:
Local resident's average > National average
A hypothesis is a theory put up to explain a phenomenon. A hypothesis must be testable according to the scientific method for it to be considered a scientific hypothesis. Scientific hypotheses are typically based on prior observations that cannot be adequately explained by the current body of knowledge.
One of the ideas put out in the hypothesis test is the alternate hypothesis.
A researcher wants to know if people in his neighborhood have a better well-being than people nationwide.
The appropriate hypothesis for a one-tailed or directional z test for the test will be that the average local residents are higher than the national average.

suppose there are two candidates for elected office. explain how the facts that a) voting might not be compulsory and b) resources are needed to finance reelection campaigns affect the conclusions of the median voter model.
The fact that voting might not be compulsory will make the voter ranks the candidate as their proximity, and the median voter wins the vote
The fact that resources are needed to finance reelection campaigns will make the probability of the median voter be in danger
According to median voter model theorem, at-least there must be two candidates
Being that we have two candidates for elected office, let's see how the following may affect the conclusions of the median voter model:
Part a
Voting might not be compulsory:
Here, voter ranks the candidates as per as their proximity, and the median voter will win the vote.
Part b
Resources are needed to finance re-election campaign :
When resources are needed to finance reelection campaign, none can cast their votes and it will distort this strategy. So the probability of median voter is in danger.

a potter forms a piece of clay into a right circular cylinder. as she rolls it, the height h of the cylinder increases and the radius r decreases. assume that no clay is lost in the process. suppose the height of the cylinder is increasing by 0.5 centimeters per second. what is the rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters?
The rate at which the radius is changing when the radius is 7 centimeters and the height is 6 centimeters is -0.8571 cm/s
dr/dt = -0.8571 cm/s
A cylinder's volume can be calculated using...
V = πr²h
For a constant volume, by differentiating with respect to t, we obtain...
0 = π(2rh·dr/dt + r²·dh/dt)
Finding for dr/dt, we have ...
dr/dt = dh/dt(-r²/(2rh)) = (dh/dt)(-r/(2h))
Filling in the given numbers gives ...
dr/dt = (0.5 cm/s)(-7 cm)/(2·6 cm)
dr/dt = -0.8571 cm/s

Answer:
Width = 10 in
Length = 50 in
Step-by-step explanation:
Define the variables
Let x be the width of the rectangle.If the length is five times its width, then the length of the rectangle is 5x.Given the perimeter is 120 in:
