A store marks up merchandise 27%. The original price of an item is $725. What will be the retail price?
Answer:
$168
Step-by-step explanation:
cause the store marks up the price by 115%
The original price of the item was $725
Store increases the margin by 27%
Let us assume the retail price to be x
To get the retail price we need to add the margin added by the store to the original price which is $725 in this case.
So,
x= 725 × 127/100
x= 92075/100
x= 920.75
Another method-
Let retail price be x
Since the original price of the item is $725
The store increases the price by 27%
Add 27% of $725 to the original price to get the retail price
725 × 27/100
= $195.75
Add 195.75 to the original price to get the retail price
x= 195.75+ 725
x= 920.75
The Retail price which will be charged by the store on the merchandise will be $920.75

A computer salesman makes $10 per hour and 0.5% commission on what he sales. If he works for 40 hours this week, and he sales $4,500 of computers, how much will he make total?
Answer:
Total income earn = $422.5
Step-by-step explanation:
Given:
Earning per hour work = $10
Total hour = 40
Commission = 0.5% on sales
Total sales = $4,500
Find:
Total income earn
Computation:
Income from hour work = $10 x 40
Income from hour work = $400
Total commission = 0.5% x sales
Total commission = 0.5% x $4,500
Total commission = $22.5
Total income earn = $400 + $22.5
Total income earn = $422.5
A grocery store clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. Which number could represent the number of packages of flour tortillas the clerk put on the shelf?
Answer: 18
Step-by-step explanation:
The options are:
A. 23
B. 18
C. 14
D. 32
Since we are told that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. This simply means that the ratio of flour tortillas to the total number of packages on the shelf was (16 -7 = 9) 9 to 16.
Therefore, to get the number that could represent the number of packages of flour tortillas the clerk put on the shelf we have to find the multiple of 9 in the question given . This will be:
Multiples of 9 = 9, 18, 27, 36, 45 ....
Based on the option, the answer will be 18.

Use what you know to try to solve the problem below. A scientist is using a tracking device to measure how fast a blue whale swims. Data from the device show that the whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Make a graph showing the change in the whales distance over time. How far does the blue whale swim in 1 minute? this 25 mi: 5
The graph showing the change in the whales distance over time is given by y = 0.5x
How to solve an equation?An equation is an expression that shows the relationship between two or more numbers.
The standard form of a linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept.
Let y represent the total distance covered for x minutes.
Let the constant rate be m miles per minute. The whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Hence:
2.5 = 5(m)
m = 0.5 miles per minute
y = 0.5x
In 1 minute:
y = 0.5(1) = 0.5 miles
The graph is given by y = 0.5x

The longest leg of a right triangle is 12 inches. The hypotenuse is 3 inches longer then twice the shortest leg. How long is the shortest leg and the hypotenuse of the triangle.
Answer:
Shortest Leg: 5 inches, Hypotenuse: 13 inches
Step-by-step explanation:
A right triangle follows the pythagorean theorem, a^2+b^2=c^2. C is the hypotenus. A combination found using this is 5, 12, and 13. To double check this, we know that the hypotenus is 2x+3, where x is the smallest leg.

8. Complete the statement using <, >, or =.
a. 21-51
b. -5__ _|−9|
|5|_________|-5|
d. |−1|___________|—8|
C.
We can complete the given statements as follows-
a. 21 < 51
b. -5< |-9|
c. |5| = |-5|
d. |−1|< |-8|
Let us look at each statement one by one-
a. 21_51
here, we can clearly see that 21 is smaller than 51, so we use the < sign.
Thus, 21 < 51
b. -5_|-9|
here, on the right hand side we have a modulus sign. The modulus sign implies that we take only the absolute value.
|−9| = 9
Now, if we compare -5 and 9, 9 is clearly greater.
Hence, -5< |-9|
c. |5|__|-5|
here, |5| = 5
and |-5| = 5
Thus, |5| = |-5|
d. |−1|__|-8|
Here, |−1| = 1
and |—8| = 8
And 1 < 8,
thus, |−1|< |-8|

one important point to remember is that just because a difference between two treatment groups is found to be statistically significant, it does not mean that the difference:
Researchers use a finding's Effect size to measure magnitude and reliability.
a difference in significance does not always make a significant difference.
One reason is the arbitrary nature of the p<0.05 cutoff. We could get two very similar results, with p=0.04 and p=0.06, and mistakenly say they’re clearly different from each other simply because they fall on opposite sides of the cutoff.
The second reason is that p values are not measures of effect size, so similar p values do not always mean similar effects. Two results with identical statistical significance can nonetheless contradict each other.
Effect size refers to the measure of the magnitude of the experiment's effect. In other words, effect size measures how important is the relationship between two variables. The larger the effect size, the stronger this relationship is. Moreover, when the effect size is large, you are more likely to be dealing with a relationship that has practical significance.

In the parallelogram shown, AE = t + 2, CE = 3t − 14, and DE = 2t + 8. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. What is the length of line segment DB? 20 units 24 units 48 units 68 units
Answer:
48 units
Step-by-step explanation:
A parallelogram is a polygon with four sides. Opposite sides and opposite angles of a parallelogram are congruent.
The diagonals of a parallelogram bisect each other.
In parallelogram ABCD, AC and DB are the diagonals. Since the diagonals meet at E, hence:
AE = CE and DE = BE (diagonals of a parallelogram bisect each other).
Since AE = CE, hence:
t + 2 = 3t - 14
3t - t = 2 + 14
2t = 16
t = 8 units
Therefore DE = 2t + 8 = 2(8) + 8 = 24 units
DE = BE = 24 units
But DB = DE + BE
DB = 24 + 24
DB = 48 units
Answer:
The answer is 48 units

What are the dimensions?The formulae that can be used to determine the dimensions when the ratio of the dimensions are given and the diagonal is given are:
h = [tex]\frac{H}{\sqrt{ 1 + r^{2} } }[/tex]
w = [tex]\frac{Hh}{\sqrt{ 1 + r^{2} } }[/tex]
Where:

Mr. majors ordered six hot dogs and a bucket of popcorn at the concession stand. if the popcorn was $3.20 and the total was $18.20, what was the price of one hot dog?
Answer:
The price of one hotdog is $2.50
Step-by-step explanation:
You can first write this out as an equation to make it easier to solve.
Lets say that x= the price of a hot dog and y= the price of popcorn
The equation would be:
6x + y = 18.20
We know that y= 3.20 so we can subtract 3.20 from 18.20. That will leave us with 6x = 15
Then, we just have to divide both sides by 6 and our answer comes out as x = 2.50
Answer:
2.50
Step-by-step explanation:
18.20 - 3.20 = 15.00
15.00 ÷ 6(hotdogs) = 2.5
Add a 0 at the end: 2.50
So the cost of one hotdog is $2.50
( why does that hot dog cost that much ;-; )
