Answer:
-37%
Step-by-step explanation:
work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100
5-8=-3
-3/8*100= -37.5%
Answer:
-37%
Step-by-step explanation:
work out the difference between the two numbers you are comparing.
Then: divide the increase by the original number and multiply the answer by 100.5-8=-3
-3/8*100= -37.5%Answer:
-37%
How many terms are there in this linear polynomial? 2 m - n + 3
Answer:
3
Step-by-step explanation:
A term is any part of the equation that is separate from another part. In the equation, 2m - n + 3, 2m is a term because they are not separate, n is a term, and 3 is a term. I hope this helps and I hope it's not wrong but I don't think it is.

Kaleb has 45 DVD's in his collection and Eileen has 61. If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month, after how many months will Kaleb and Eileen have the same amount of DVD's?
Answer: After 8 months they will have equal number of DVD's.
Step-by-step explanation:
Given: Kaleb has 45 DVD's in his collection and Eileen has 61.
Let x= Number of months
If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month , then
Total DVD's Kaleb has = 45+4x
Total DVD's Eileen has = 61+2x
When they has equal DVD's , then
[tex]45+4x =61+2x\\\\\Rightarrow\ 4x-2x=61-45\\\\\Rightarrow\ 2x=16\\\\\Rightarrow\ x=\dfrac{16}{2}\\\\\Rightarrow\ x=8[/tex]
Hence, after 8 months they will have equal number of DVD's.

Graph the lines given by the following equations:
y=3-1/2x
To calculate the y position given an x value, multiply the x value by -2 and subtract 3.
Answer:
switch the equation around so it looks like the slope intercept form
y= Mx + b
Step-by-step explanation:
y=3 - 1/2x
y= -1/2x +3
so when x = 0 you know this line is at 3 on the y axis
make a point on the graph at (0,3)
also you know that when x=6 they y is zero.. so
make a point on the graph at (6,0)
now draw a straight line between those two points on your graph :)
How would I find the x-intercept and the y-intercept for the equation: 6x+5y=−60?
Answer:
use the slope intercept form of the equation
y = Mx +b
Step-by-step explanation:
6x+5y = -60
5y = -6x - 60
y = (-6/5)x -12
now just plug in zero for x in that above equation ... that will be the y intercept -12
and plug in zero for y and solve for x
0 = (-6/5)x -12
12= -6/5x
(-5/6)(12) = x
-10 = x

Which algebraic expression represents the phrase "seven more than half of a number”?
o 7 -1/2x
o -7+1/2x
o 1/2x+7
o -1/2x-7
PLEASE HELPPPP
Answer:
C
Step-by-step explanation:
Seven more is addition (+7)
Half a number would be represented by 1/2, and since the number is unknown, it would be represented by a variable (in this case, x)
C is the correct response
Hope this helps!
Decide whether there is enough information to prove that r is parallel to s. If so, state the theorem you would use.
A. No, there is not enough information.
B. Yes. Alternate Interior Angles Converse
C. Yes. Alternate Exterior Angles Converse
D. Yes.Consecutive Interior Angles Converse
E. Yes. Corresponding Angles Converse
Answer:
B. Yes. Alternate Interior Angles Converse
Step-by-step explanation:
The two angles shown in the figure above are alternate interior angles. Each is located within the two parallel lines intersected by the transversal, and they also lie on opposite side of the transversal.
The marked alternate interior angles are congruent. Therefore, lines r and s are parallel. So, by the Alternate Interior Angles Converse, lines r and s are parallel.
Therefore, the right response to the question is:
"B. Yes. Alternate Interior Angles Converse".
To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph. She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph. At what time will Amanda get to work if she leaves home at 8:30 AM?
Answer:
9:45 AM
Step-by-step explanation:
To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph.
Time (hours) = Distance/speed
Hence, the time she spends cycling = 10mile/12 mph
= 0.8333333333 hour
Converting to minutes:
1 hour = 60 minutes
0.8333333333 hour =
0.8333333333 hours × 60 minutes/1 hour
= 50 minutes.
Hence, she spends 50 minutes cycling
She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph.
The total number of minutes she spends to get to work is calculated as:
(50 + 10 + 15)minutes
= 75 minutes.
It takes Amanda 75 minutes to get to work.
At what time will Amanda get to work if she leaves home at 8:30 AM?
= 8:30AM + 75 minutes
= 8:30 AM + 1 hour 15 minutes
= 9:45 AM

A 20 foot ladder leans against a house the base of the ladder is 12 feet from the house. What is the distance from the ground to the top of the ladder?
Answer:
16ft
Step-by-step explanation:
Please see attached diagram depicting the above scenario.
Since the ladder leans against a house, then it forms a right angled triangle while the hypothenus is 20 foot, the distance of the base of the ladder is 12 feet from the house, hence we are required to find the point at which the ladder touches the house I.e height, rep by h.
We will apply Pythagoras theorem to solve the problem.
h^2 = 20^2 - 12^2
h^2 = 400 - 144
h^ 2 = 256
h = √256
h = 16ft
Hence, the distance from the ground to the top of the ladder is 16ft.

Nick has $3.90 in quarters and dimes, and the total number of coins is 27. How many quarters and how many dimes? Can I have some help with formatting?
Answer:
There are 19 dimes and 8 quarters
Step-by-step explanation: Q= Quarter and D=dimes
q+d= 27; q=.25 and d=.10;
.25q+.10d= $3.90
q= 27-d
.25(27-d)+.10d=3.90 >Distribute .25 through the parenthesis
= 6.75-.25d+.10d=3.90 >Combine like terms
= -.15d=3.90-6.75 >Subtract 6.75 from both sides of the equation
= -.15d=-2.85 >Subtract
= d=19 >Divide both sides by -.15
q= 27-d>>>>> q= 27-19
q= 8

A standard number cube that is labeled 1 through 6 is rolled 150 times. What is a reasonable prediction for the number of times it will land on a 3 or a 4?
Answer:
100 times
Step-by-step explanation:
Mathematically, the probability of getting a 3 or 4 is the probability of getting a 3 + probability of getting a 4
Probability of getting a 3 = number of 3/total number = 1/6
Probability of getting a 4 = number of 4/total number = 1/6
Thus, the probability of getting a 3 or 4 is 1/6 + 1/6 = 2/3
So the number of times will be probability multiply by number of rolls
= 2/3 * 150 = 100 times

Emily wants to have her résumé printed. The printing company charges $24.50 for the first 100 résumés, and then a flat rate for each additional 100 résumés. Emily pays $48.50 for 300 résumés. Write a piecewise function that describes this situation. r(x) = and calculate how much is the flat rate for each additional set of 100 résumés after the first 100 résumés are purchased? Please label your answer and round to two decimal places (hundredths) if needed.
Answer:
________{$24.50 if x ≤ 1
r(x) - - - - - {24.50 + f(3 - 2) if x > 1
Flat rate paid for each additional 100 = $12
Step-by-step explanation:
Given that :
Cost of first 100 resume = $24.50
Flat rate for each additional 100 resumes
Total amount paid for 300 resumes = $48.50
Let x = number of sets of 100 resumes
Number of sets of 100 copies = {1, 2, 3}
Since first 100 copies = $24.50
r(x) = cost of printing resume
r(x) = 24.50 if x ≤ 1
Cost of additional 100 equals ;
Let flat rate paid for each additional 100 = f
r(x) = 24.50 + f(3 - 1) if x > 1
________{$24.50 if x ≤ 1
r(x) - - - - - {24.50 + f(3 - 2) if x > 1
The flat rate paid for additional 100 resume ;
(Total amount paid - cost of first 100) / 2
($48.50 - $24.50) / 2
$24 / 2
= $12
