Given that ,
The sweater shack is offering 20% discount,
and the regular price is $ 15 .00,
so, the discount given would be
⇢ $ 15 x 20/100
⇢$ 15 x 0.2
⇢$ 3
selling price⇢Regular price - Discount price
⇢$15 - $(20/100 x 15)
⇢$15 - $3
⇢$12
Answer 2↷Given that,
20% out of 30 students scored an A in previous math test,
so ,the number of students who got an A in the test
⇢ 30 x 20/100
⇢30 x 0.2
⇢6
Hence ,6 students secured an A grade in last math test
Answer 3↷Given that,
The Jean junction is selling the jeans at the discount rate of 15% of the regular price which is $25.00,
so, the discount is
⇢$25.00 x $ ( 15/100 )
⇢$25.00 x $ 0.15
⇢$3.75
selling price⇢ $25.00 - $25.00 x $ ( 15/100 )
⇢$25.00- $25.00 x $ 0.15
⇢$25.00 -$3.75
⇢$21.25

50 - 9 = 40 + 1Suzie had a 49-question quiz, and she received 59.2%, but 12 questions weren't graded yet.
If all 12 questions are correct, what is the new percentage?
Based on the number of questions in the quiz that Suzie did, if 12 questions were not graded and they were all correct, the new percentage on the quiz is 69.4%
How to find the new percentage?There were 49 questions in the quiz and 12 were not graded. The number that was graded was;
= 49 - 12
= 37 questions
She got 59.2% which means that the number of questions Suzie got correct were:
= 37 x 59.2%
= 21.9
= 22 answers
If the 12 questions were correct, the new percentage would be:
= (22 + 12) / 49 x 100%
= 34 / 49 x 100%
= 0.693877551 x 100%
= 69.4%

SAVINGS Natalie has $250 in her savings accountinto which she deposits $10 of her allowance each week. The balance of her savings account can be modeled by the function f(w) = 250 + 10w , where w represents the number of weeks. Write a function g(w) to represent the balance of Natalie's savings account if she withdraws $40 to purchase a new pair of shoes. Describe the translation of f(w) that results in g(w) .
Answer:
[tex]g(w) = 210+ 10w[/tex]
Step-by-step explanation:
Given
[tex]f(w) = 250 + 10w[/tex]
[tex]Withdrawal = \$40[/tex]
Required
Determine g(w)
First, we'll write an expression for g(w)
From the question, we understand that she withdrew $40 from her account balance in w weeks.
This implies that:
[tex]g(w) = f(w) - 40[/tex]
Where f(w) is the account balance in w weeks and $40 is the withdrawn amount
Substitute 250 + 10w for f(w)
[tex]g(w) = 250 + 10w - 40[/tex]
Collect Like Terms
[tex]g(w) = 250 - 40+ 10w[/tex]
[tex]g(w) = 210+ 10w[/tex]
Recall that:
[tex]g(w) = f(w) - 40[/tex]
This means that function f(w) when shifter by 40 units downward, gives g(w)
The cost of making a phone is $152. A store sells the phone for $281.20.
Select all the expressions that could be used to find the percentage of markup for the phone.
Answer:
The store is selling the phone by 185% of its value...
Step-by-step explanation:
You just gotta divide 281.20 (the value of the phone at the store), and divide it up by 152 (its original value). And multiply the result by 100 to get the percentage.
[tex](\frac{281.00}{152})(100) = (1.85)(100) = 185%[/tex]%

Step-by-step explanation:
The function h(x) passes through the point (-8,9). What point must lie on h^-1(x)?
Answer:
Step-by-step explanation:
h^-1(x) is the inverse of h(x) so its graph is the reflection of h(x)
in the lines y =- x.
This reflection is (x, y) ---> (y , x)
So the required point is (9, -8)
The point (9, -8) must lie on the inverse function [tex]h^{(-1)}(x)[/tex].
To find the point that must lie on the inverse function [tex]h^{(-1)}(x)[/tex], use the fact that points on the original function and its inverse are reflections over the line y = x.
If the point (-8, 9) lies on the function h(x), then the inverse function [tex]h^{(-1)[/tex](x) will have a point that is the reflection of (-8, 9) over the line y = x.
The coordinates of the reflected point will simply swap the x and y values. So, the point that must lie on [tex]h^{(-1)[/tex](x) is (9, -8).
Therefore, the point (9, -8) lie on the function [tex]h^{(-1)}(x)[/tex].

Find the slope of the line through the given points:
(-3,-4) and (5, 12)
Leave answer as a fraction.
slope =
Blank 1:
Step-by-step explanation:
the slope is (y coordinate change / x coordinate change) when going from one point on the line to another.
it does not matter in what direction we go, but it is important to keep the same direction for the x and the y comparison.
because I prefer to go from left to right, let's go from
(-3, -4) to (5, 12).
x changes by +8 (from -3 to 5).
y changes by +16 (from -4 to 12).
so, the slope is
+16/+8 = 2/1 = 2

Find the measure of angle A
Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:

a. B, C, A
b. C, A, B
C. B,A,C
d. A,B,C
e. A,C,B
f. CB, A
Answer:
The list of angles of the triangle in order from smallest to largest will be: A < C < B
Hence, option 'e' is true.
i.e (A,C,B)
Step-by-step explanation:
We know that in a triangle the greater angle has the longer side opposite to it.
From the given triangle,
Side AC = 7.2 is the longer side. Thus, B is the largest angle as it is opposite to the longer side AC = 7.2.
Then comes the second-longest side AB=4.9. Thus, C is the 2nd largest angle it is opposite to the second-longest side AB=4.9.
Finally comes the shortest side BC = 3.2. Thus, A is the shortest angle as it is opposite to the shortest side BC = 3.2.
Thus, the list of angles of the triangle in order from smallest to largest will be: A < C < B
Hence, option 'e' is true.
i.e (A,C,B)
Which value of m will create a system of parallel lines with no solution?
y=mx-6
8x-4y=12
Answer:
m = 2
Step-by-step explanation:
Rearrange the second equation into slope-intercept form (so that it is formatted the same as the first equation)
8x - 4y = 12
8x - 8x - 4y = -8x + 12
-4y = -8x + 12
-4y/-4 = (-8x + 12)/-4
y = 2x - 3
The slope for this equation is 2.
Equations with the same slope are parallel and therefore have no solution since they can never intersect. Hence, the required value of m is 2.
