Macy's buys a coat from the manufacturer for $22.00. They markup the coat by 75%. Ms. Tonyes buys the coat and uses a 15% off coupon. How much does Ms. Tonyes pay for the coat before tax?
Answer:
Toney buys the coat for $ 14.8.
Step-by-step explanation:
Cost of coat =$ 22
Mark up by 75 %
discount = 10 %
Let toney pay $ R for the coat.
So, according to the question
R + 75 % R = 1.75 R
Now the cost is
1.75 R - 15 % of 1.75 R = 22
1.75 R - 0.2625 R = 22
R = 14.8
So, he buy the coat for $ 14.8.

Answer:
b = 7.14cm
Step-by-step explanation:
For this question, we need to use the pythagorean theorem, since it is a right triangle, and we know two sides. The formula for the Pythagorean theorem is c^2 = a^2 + b^2.
1. a = 5.8cm so a^2 will be 5.8 x 5.8 which is 33.64
2. c = 9.2cm so c^2 will be 9.2 x 9.2 which is 84.64
3. If we add these to our Pythagorean equation, it will be 84.64 = 33.64 + b^2. --> 51 = b^2 --> b = 7.141428....
4. Since we need to round it to two decimal places, b will be 7.14.

The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:
a) 16
b) 14
c) 32
d)28
Answer:
40
Step-by-step explanation:
Let the numbers be 2x and 3x
Then their L.C.M. = 6x
BUT also their LCM=48
6x=48
x=48/6
x=8
So,
First number=2x=2x8=16
Second number=3x=3x8=24
The numbers are 16 and 24.
Hence required sum =(16+24)=40
So none of the options are correct
find the slope of a line parallel to given line.
Answer:
-3
Step-by-step explanation:
If lines are parallel to each other, they will never touch so the slope will be the same.
So if the first line is already given in slope intercept form, that means the -3 is the slope.
So a line parallel to this would have the slope -3 and start at a different place on the y axis.

If y=-2x+6 wee changed to y=3x+2 how would the graph of the new line compare with the first one
Answer: (a)
Step-by-step explanation:
Given
The given graph is y=-2x+6 and it changed to y=3x+2
The slope of the graph determines the steepness
Slope changes from -2 to 3. So, latter graph is more steeper.
Also, y intercept is obtained by putting x as 0
Y intercept changes from 6 to 2 i.e. decrease of 4 units
Hence, option (a) is correct.
Two positive numbers have a difference of 21. The larger number is five more than twice the smaller. Find the two numbers.
Answer:
X = 29
Y = 8
Step-by-step explanation:
X - y = 21
X = 2y + 5
Substitute:
2y+5-y= 21
2y = 16
Y = 8
X-8 = 21
X = 29
What are the coordinates of the hole in the graph of the function?
f (x) = x^2 − 3x − 10
x−5
Enter your answer in the boxes.
Answer:
The hole is at (5,7)
Step-by-step explanation:
x^2 − 3x − 10
-------------------
x−5
Factor the numerator
(x-5)(x+2)
-------------------
x−5
There is a hole at x=5 since it will cancel in the numerator and the denominator
f(x) = x+2 and letting x = 5
f(5) = 5+2
The hole is at (5,7)

Find a point on the line and the line's slope.
y+4=-3/2(x+7)
Answer:
The slope is 3/2 and a point on the line is (-7,-4)
Step-by-step explanation:
Point slope form of a line is
y -y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y+4=-3/2(x+7)
y - -4 = 3/2 ( x - -7)
The slope is 3/2 and a point on the line is (-7,-4)

A city has a population of 340,000 people. Suppose that each year the population grows by 5.25%. What will the population be after 15 years?
Answer:
Future population = 720800
Step-by-step explanation:
Below is the calculation of population after 15 years.
Given the present population = 340000
Growth in population = 5.25%
Use below formula to find the values:
Future population = Present population ( 1 + r)^n
Future population = 340000 ( 1 + 5.25%)^15
Future population = 340000 (2.15)
Future population = 720800

Given:
The inequality is:

To find:
The inequality after isolating the y-term.
Solution:
We have,
[tex]y+2>\dfrac{1}{3}(6x+9)[/tex]
On simplification, we get
[tex]y+2>\dfrac{1}{3}(6x)+\dfrac{1}{3}(9)[/tex]
[tex]y+2>2x+3[/tex]
Subtracting 2 from both sides of the above inequality, we get

[tex]y>2x+1[/tex]
Therefore, the required inequality is [tex]y>2x+1[/tex].

Answer:
Arc AB = 110
Step-by-step explanation:
<C = 55 degrees. That's the way the triangle is marked. AB = BC.
The central angle is twice the angle made by the end points of line AB
The central angle = 2*55 = 110
The measure of arc AB equals the central angle which makes arc AB = 110

Use the Pythagorean theorem to classify the triangle
formed by the three fences. Which is true about the
numbers 5, 12, and 13?
Answer:
they are equal
Step-by-step explanation:
The triangle with sides 5, 12, 13 is a right triangle because
a^2+b^2 = c^2
5^2+12^2 = 13^2
25+144 = 169

A company plans to reduce the amount of energy used each year. This table shows the company's plan.
Answer:
the anserw would be B
Step-by-step explanation:
The relationship that explains the exponential relationship between the year and amount of energy used is: Option B: The amount of energy used decreases by different amount each year.
What is the rate of exponential function?Rate of an exponential function is in terms of exponential function itself. It's not constant, and always changing. For example, the rate of [tex]y = e^x[/tex] with respect to x is [tex]y' = e^x[/tex] itself, which increases as x increases.
The given table is:
Year(Serial no.) Amount of energy used (kWh)
1 1,000,000
2 900,000
3 810,000
4 792,000
The differences between each consequent years of the amount of energy used is:
1000000 - 900000 = 100000
900000 - 810000 = 90000
810000 - 792000 = 18000
So, we see that the decrement is done by decreasing amount.
So rate of change wasn't constant but continuosly changing.
Thus, Option C is clearly wrong.
We see that 100,000 is 10% of 1,000,000
and 90,000 is 10% of next years amount 900,000
but 18,000 is not 10% of next years amount which is 810,000
Thus, Option A is wrong too.
Option B is correct in its statement, and so as option D because we don't see any immediate pattern in the decrement, except that the energy is just decreasing, so its unexpected.
The rate of exponentially related variables is not unexpected though.
So, its only Option B which is closest (among other options) to the intention of telling that the relation between the year and the amount of energy used is exponential, although it doesn't prove that the relationship is exponential. (because, suppose the function i take is [tex]y = x^2[/tex], then its rate with respect to x is [tex]y' = 2x[/tex] and this rate is also non-constant, but the function wasn't exponential).
Thus, the relationship that explains the exponential relationship between the year and amount of energy used is: Option B: The amount of energy used decreases by different amount each year.
