A candy store uses a 50% markup on cost. Find out the owners cost of a candy bar that sells for $1.50.
Answer:
The owners' cost of the candy bar is $1
Step-by-step explanation:
Assume that the owners' cost of the candy bar is 100%
∵ The owners' cost of the candy bar is 100%
∵ The candy store uses a 50% markup on cost
∵ The selling cost = owners' cost + markup
∴ The selling cost = 100% + 50% = 150%
∵ The candy bar sells for $1.50
→ That means 1.50 is 150% of the owners' cost
∴ 1.50 = 150% × owners' cost
→ Change 150% to decimal by divide it by 100
∵ 150% = 150 ÷ 100 = 1.50
∴ 1.50 = 1.50 × owners' cost
→ Divide both sides by 1.50
∴ 1 = owners' cost
∴ The owners' costs = $1
∴ The owners' cost of the candy bar is $1
will someone tell me the equation for this word problem.
will give brainliest
Answer:
5c + 3d = 55
4c + 3d = 53
Step-by-step explanation:
lets pretend c= cost of chicken, d= cost of duck
5 chickens total cost would be 5c
3 ducks total cost would be 3d
in equation one added together would be 55 for total cost (given in word problem).
repeat for second equation.
please give thanks :)
50 points on god if yall can get this
Step-by-step explanation:
The price of a game discounted by 18% is 0.82x cuz 82% is left
the price of the toy is 1.18x because x + 0.18x
the volume of water is 7/10x because 7/10 is left
the total amount of flour is 13/10x because 10/10x + 3/10x
-5x-4y=10
y intersect: (____ ; ____)
x intersect: (____; _____)
see picture above. dont answer if u dont know. first gets marked brainliest!!
Answer:
y intercept = [tex](0, ~-\frac{5}{2} )[/tex]
x intercept = [tex](-2, ~0)[/tex]
.
Step-by-step explanation:
[tex]-5x - 5y = 10[/tex]
.
y intercept
[tex]\to x = 0[/tex]
[tex]-5(0) - 4y = 10[/tex]
[tex]-4y = 10[/tex]
[tex]y = \frac{10}{-4}[/tex]
[tex]y = -\frac{5}{2}[/tex]
so, the answer is [tex](0, ~-\frac{5}{2} )[/tex]
.
x intercept
[tex]\to y = 0[/tex]
[tex]-5x - 4(0) = 10[/tex]
[tex]-5x = 10[/tex]
[tex]x = \frac{10}{-5}[/tex]
[tex]x = -2[/tex]
so, the answer is [tex](-2, ~0)[/tex]
.

In a school with 700 students, a survey revealed that 80% of the students liked the new lunch menu. Based on this data, how many students liked the new menu?
Answer:
560 students
Step-by-step explanation:
We are given that the total number of students is
700
The survey results is 80% likes the new lunch menu
We are expected to establish what amount of students is 80%
=80/100*700
=0.8*700
=560
Hence 80% of 700 is 560

Aaron ran 5/8 mile to his friend's house. Then he ran another 1/4 mile to the park.
Complete question : Aaron ran 5/8 mile to his friend's house. Then he ran another 1/4 mile to the park. Find Aaron's total miles ran?
Answer:
7/8 miles
Step-by-step explanation:
Given that:
Distance to friend's house = 5/8 miles
Then, Distance to park = 1/4 miles
Total. Distance ran :
(5/8 + 1/4)
L.C.M of 4 and 8 = 8
(5 + 2) / 8 = 7/8 miles
Total distance ran = 7/8 miles
The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 5 points. Apply chebychev's theorem to the data using k= 12 interpret the results
Answer:
Interpreting the results:
a) At least 99.3% of the data lies between 12 standard deviations of the mean
b) The data lies between points 0 and 168
Step-by-step explanation:
The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 5 points. Apply chebychev's theorem to the data using k= 12 interpret the results
Chebychev's theorem states that:
At least 1 - 1/k² data lies between k standard deviation of the mean
μ ± kσ
Where k is a positive number greater than 1
From the question above
μ = Mean = 84 points
σ = Standard deviation = 5 points
Hence: k = 12
We have:
1 - 1/12²
= 1 - 1/144
= 144 - 1/144
= 143/144
= 0.9930555556
Approximately = 99.3%
Interpreting these results means that At least 99.3% of the data lies between 12 standard deviations of the mean
Hence,
μ - kσ
84 - 12 × 7
= 84 - 84
= 0
μ + kσ
84 + 12 × 7
= 84 + 84
= 168
Hence, the data lies between points 0 and 168
State which theorem you can use to show that the quadrilateral is a parallelogram.
Answer:
We can use the theorem ''Parallelogram Diagonals Converse'' to show that the quadrilateral is a parallelogram.
Step-by-step explanation:
We know that the diagonals of any parallelogram bisect each other, each diagonal cutting the other into two equal parts.
In other words, according to Parallelogram Diagonals Theorem Converse, the figure will be a parallelogram if the diagonals of the quadrilateral figure cut (bisect) each other. It is basically the
From the given Parallelogram, it is clear that the diagonals bisect each other, each diagonal cutting the other into two equal parts with the length 3 units.
Therefore, we can use the theorem ''Parallelogram Diagonals Converse'' to show that the quadrilateral is a parallelogram.

Katherine invested $86,000 in an account paying an interest rate of 52%
compounded daily. Michael invested $86,000 in an account paying an interest rate of
5% compounded continuously. After 13 years, how much more money would
Katherine have in her account than Michael, to the nearest dollar?
Answer: $4,331
Step-by-step explanation:
I will assume that the question meant 5.2% not 52% as this is quite excessive.
Katherine after 13 years.
Convert the variables;
n = 13 years = 13 * 365 = 4,745 days
r = 5.2% = 5.2/365 = 5.2/365%
Future value = P * ( 1 + r)^n
= 86,000 * (1 + 5.2/365%)⁴⁷⁴⁵
= $169,068
Michael after 13 years;
If compounded continuously, the formula is;
Future value = Pe^rt
= 86,000 * e⁰.⁰⁵ ˣ ¹³
= $164,737
Difference = 169,068 - 164,737
= $4,331
Gianna has 20 cookies in a bag. 20% of the cookies are vanilla. How many cookies are vanilla?
Answer:
4 cookies are vanilla
Step-by-step explanation:
because 20% is technically 1/5th of 100% we need to divide 20 by 5
20/5 = 4
A college has a financial aid formula that applies to applicants whose family's income is below a certain threshold. The financial aid can be determined by the function f(x)=15000+3000x, where x is the number of siblings (including half siblings and step siblings) that the applicant has living in their household. Find and interpret the given function values and determine an appropriate domain for the function.
PLZ HELP!
Answer:
This equation shows you how financial aid increases $3000 for every additional sibling, starting at $15,000.
Step-by-step explanation:
This equation means that for every sibling there is an additional $3000 in financial aid. When there are no siblings there is an automatic $15000 in financial aid.
Since you can't have "negative number" of siblings, the domain must begin with 0. You can have a lot of siblings, so let's put the end of domain as infinity.
Domain = [0, ∞)
If you substitute in this domain into the equation, the range will be the output. The least will be $15,000 and the most will be infinity as well.
Range = [15000, ∞)

Use (2, 16) and (4,32) to find the constant of proportionality.
The unit rate (constant of proportionality) is
miles
hour
(Simplify your answer
Answer:
8 miles per hour
Step-by-step explanation:
First find the slope. The slope is the unit rate/constant of proportionality.
To find slope use the points given and formula y2-y1 / x2-x1
(32-16) / (4-2)
= 16 / 2
= 8
Thus the unit rate is 8 miles per hour.

The combined volume of all the tanks at an aquarium is 1.25×10^6 gallons. The aquarium plans to install a new dolphin yank with the volume of 250 gallons. What would be the total of all of the tanks at the aquarium after the new dolphin tank is installed?
Answer:
1,250,250 gallons
Step-by-step explanation:
1.25 * 10^6 gallons = 1,250,000 gallons
1,250,000 gallons + 250 gallons = 1,250,250 gallons
the sum of 2 numbers is 49. Twice the smaller number is 97 less than 3 times the larger number. What are the numbers?
Answer:
let the larger and smaller number be x and y respectively
first condition
x + y = 49
second condition
3x = 2y+97
3x-2y =97
Multiplying first condition by two and adding both equations
2x + 2y = 98
3x -2y = 97
5x = 195
x = 195/5 = 39
putting the value of x in
x + y = 49
y = 49 -39 = 10
