A pair of shoes that normally sells for $85.00 goes on sale for 35% off.
Sean thinks that the sale price should be $50.00 but Melanie disagrees and says the price should be $55.25. Aiyanna says they are both wrong and decides the price should be $29.75.
Who is correct and why?
a. Melanie is correct.
b. Sean is correct.
c. Aiyanna is correct.
Answer:
A
Step-by-step explanation:
Melanie is correct
85 x 0.35 = 29.75
85 - 29.75 = 55.25
Answer:
a. Melanie is correct
Step-by-step explanation:
35% of 85= 29.75
*Find this by finding 10% (move decimal place over) and five percent (half of ten percent) and add triple of 10% plus the 5% or look it up*
Subtract this from 85
85-29.75=
$55.25

A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing
books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
Answer:
O no, because people in the bookstore are interested in purchasing books, so they do not represent all shoppers in the mall
Step-by-step explanation:
In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.
Doing this, would help to give an accurate representation of both group in the survey.
One of the base angles in an isosceles triangle is 75 degrees, then its exterior angle is
A. 105 degrees
B.75 degrees
C. 285 degrees
D, 30 degrees
Answer:
105 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
You just gotta subtract your given (in your case 75) from 180 to get your answer my guy
Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?
Answer:
54 years
Step-by-step explanation:
Given that :
Let :
Ann's age = x
Mary's age = x/2
Donald's age = x/3
x + x/2 + x/3 = 99
Take the L. C. M
(6x + 3x + 2x) / 6 = 99
11x / 6 = 99
11x = 99 * 6
11x = 594
x = 594 / 11
x = 54
Hence, Ann is 54 years
Solve the equation for x.
2/3 (6 – 9x) = 16
A) -2
B) -4
C) -9
D) -12
Answer:
A. - 2
Step-by-step explanation:
Given
2/3 ( 6 - 9x) = 16
or, 6 - 9x = 16 * 3 / 2
or, 6 - 9x = 24
or, - 9x = 24 - 6
- 9x = 18
x = 18 / - 9
Therefore x = - 2

what is the mean of 12,24,24 and 52?
Answer: 28
Step-by-step explanation: Mean will be the average of all your numbers divided by the amount of numbers you have. So
24+24+12+52=112
Now since you have 4 numbers divide 112 by 4
So your mean is 28

Simplify the ratio-
2kg : 3kg : 1.5 kg
Answer:
1.33kg : 2kg : 1kg
Step-by-step explanation:
2kg : 3kg : 1.5 kg
Given data
We have the ratio
2kg : 3kg : 1.5 kg
Let us reduce the ratio further
2/1.5: 3/1.5 : 1.5/1.5
1.33kg : 2kg : 1kg
Hence the simplified ratio is 1.33kg : 2kg : 1kg

If a student is selected at random, find the
probability the student is a freshman. Round
to the nearest whole percent.
[?]%
My
The sample space (total number of students) = 30
total number of freshmen = 7
the freshmen = the event considered
.....therefore
probability = 7/30
%probability = 7/30 × 100%
= 23.33% ~ 23%
The solution is, The required probability is 3/4= 75%, is the probability the student is a freshman.
What is the probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
here, we have,
We have to compute the probability,
P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.
Determine the total number of juniors.
Juniors=2+6=8
Since the number of females who are junior is 6, determine the required probability.
P(Female|Junior)=6/8
=3/4
=75%
Therefore, the required probability is 3/4 = 75%.
