A sweater that originally cost $40 is on sale for 10 percent off. What is the amount of the discount?
Answer:
$36
Step-by-step explanation:
orig price = $40
discount=10%
40*10/100= 400/100 = 4
$40-4= $36
Answer:
$4
Step-by-step explanation:
x percent = x/100
10 percent = 10/100 = 0.10
10% of $40 = 0.10*40 = 4
You save $4
The old price is $40 and changes to $36 after the discount is applied. This is ignoring any taxes or other surcharges

A basketball team played six games. In those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13. What was the mean difference in game scores over the six games?
Mean =sum of observations/ no.of observations
Mean=8+11+7+11+4+13/6
=54/6
mean=9
The mean difference in the game scores over six games is 2.5
What is mean difference?The mean difference measures the absolute difference between the mean value in two different groups.
Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.
The mean difference of the given data can be calculated using the following formula -
Mean Difference = (∑W / n) - (∑L / n)
Where -
(∑W / n) is the mean of games won.
and
(∑L / n) is the mean of games lost.
(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75
and
(∑L / n) = (11 + 4)/2 = 15/2 = 7.5
Mean difference = (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5
Therefore, the mean difference in the game scores over six games is 2.5

Answer:
2.7
Step-by-step explanation:
g(x)=8x+2
g( ) = -62
Answer:
-8
Step-by-step explanation:
Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.
Angle one: 2x°, angle two: xº, angle 3: (X + 8)°
Sum of all angles in a triangle = 180°
Which means :-
∠1 + ∠2 + ∠3 = 180°
[tex]2x + x + x + 8 = 180°[/tex]
[tex]4x + 8 = 180°[/tex]
[tex]4x = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]x = \frac{172}{4} [/tex]
[tex]x = 43[/tex]
Angle 1 :-
= 2x
= 2 × 43
= 86°Angle 2 :-
= x
= 43°Angle 3 :-
= x + 8
= 43 + 8
= 51°[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

what is the rate of change for y= -2/5x-9
Answer:
If two quantities x and y are related by y = f(x), the derivative f'(xo) represents the rate of change of y with respect to x at the point xo. It is measured in (units of y)/(units of x). A positive rate of change is sometimes called a rate of increase.

Step-by-step explanation:
A builder could get 6 sheets of sheetrock for $9. If he bought 12 sheets, how much money would he have spent? sheets 6 12 money 9 x (12)(6) = 6x 108 = 6x 108 = 6x 6 6 18 = x
Answer:
$18
Step-by-step explanation:
we proceed by first solving for the unit cost of a sheet
then calculate the cost for any number of sheet
We are told that a builder could buy 6 sheets for the cost of $9
this means that one sheet would cost 9/6= $1.5
Now the builder buys 12 sheets
therefore the cost of 12 sheets will be
12*1.5= $18

Y=9x-17
y = x + 23
Answer:
y=9x-17; x=17/9 or x=1 8/9 or x=1.8
y=x+23; x= -23
Step-by-step explanation:
y=9x-17
0=9x-17 (Move variables to the left-hand side and change its sign)
-9x=-17 (Divide both sides of the equation by -9)
x=17/9, x=1 8/9, or x=1.8
y=x+23
0=x+23 (To find x-intercept/zero, substitute y=0)
-x=23 (Move variable to the left-hand side and change its sign)
x= -23 (Change the signs on both sides of the equation)
x= -23
Answer:
x = 5
y = 28
the expressions both equal y so they are equal to each other. so you right the equation as
9x - 17 = x + 23
then you subtract x from both sides
and then add 17 to both sides
the final step is to divide 8 on both sides and that gives you the answer x = 5. then you plug that back into the problem so...
y = 5 +23
so y = 28.

What does it mean when they ask "What is the domain of f(x)," and the range?
Answer:the domain is all real numbers it also like the x value and the range is all y value
Step-by-step explanation:
Answer:
The domain is the set of values of "x" for which the function has meaning.
Based on my knowledge x can be any real number except for zero.
The range of f(x) is the same as finding all that y could be.
The range of f(x) is all the y values where there is a number x with y = f(x).

what is 1/10 of 4.8
Answer:
0.48
Step-by-step explanation:
Just move back one decimal point of 4.8
Answer: I just did this one lol
Step-by-step explanation:
10 percent *4.8 =
(10:100)*4.8 =
(10*4.8):100 =
48:100 = 0.48
Now we have: 10 percent of 4.8 = 0.48
Question: What is 10 percent of 4.8?
Percentage solution with steps:
Step 1: Our output value is 4.8.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$4.8=100\%$.
Step 4: Similarly, $x=10\%$.
Step 5: This results in a pair of simple equations:
$4.8=100\%(1)$.
$x=10\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{4.8}{x}=\frac{100\%}{10\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{4.8}=\frac{10}{100}$
$ x=0.48$

When the transformation (x,y) → (x + 10, y + 5) is
performed on point A, its image, point A', is on the origin
What are the coordinates of A? Justify your answer.
Answer:
its 3.05
Step-by-step explanation:
The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is performed on point A.
Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.
Since the transformation (x,y) → (x + 10, y + 5) is performed on A.
A = (0 - 10, 0 - 5)
If we are going from the pre-image to the image, we will translate to the left and downwards
A = (-10, -5)
Hence the coordinates of A will be at (-10, -5)
