Sweet Swannies Store had a sale offering 15% off all its merchandise.
Find the total discount received if I purchased the following items:
Jacket - $85
Beanie - $22
Scarf - $32
Answer:
85+22+32=139
139×15%=20.85
$20.85
or
22×15=3.30
32×15=4.80
85×15=12.75
12.75+4.80+3.30=$20.85
$20.85

Mr. David's Earnings
A. Based on the graph, is the relationship between x and y proportional?
Explain your reasoning
B. What does the point (3,90) represent in the context of this situation?
C. Based on the graph, how many dollars will Mr. David earn if he works
10 hours? Show or explain how you got your answer.
D. Write an equation that could be used to find y, the number of dollars
Mr. David earns for working x hours.
Answer:
A. Proportional by $30
B. 3 represents the hours he works
90 represents the money he earned
C. $300
D. I don know, sorry
Step-by-step explanation:
The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.
A. Based on the graph, the relationship between x and y proportional is a linear relationship.
B. The point (3,90) represents in 3 hours he earns 90 dollars.
D. The linear equation will be
[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]
C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be
y = 30x
y = 30 × 10
y = $300

Write the equation of the line that passes through the points (1, -6) and (8, 9). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
[tex]y-9 = \frac{15}{7} (x-8)[/tex]
Step-by-step explanation:
Point-slope form is represented by [tex]y-y_1 = m (x-x_1)[/tex]. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.
To find the slope, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:
[tex]\frac{(9)-(-6)}{(8)-(1)} \\= \frac{9+6}{8-1} \\= \frac{15}{7}[/tex]
Thus, the slope is [tex]\frac{15}{7}[/tex].
2) Now, using the point-slope form of [tex]y-y_1 = m (x-x_1)[/tex], substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values in order to write an equation in point-slope form. The [tex]m[/tex] represents the slope, so substitute [tex]\frac{15}{7}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for [tex]x_1[/tex] and [tex]y_1[/tex]. (I chose (8,9)). This gives the following equation and answer:
[tex]y-9 = \frac{15}{7} (x-8)[/tex]

Step-by-step explanation:
a triangle is 180 degrees
<ACB=50 (180-130=50)
50+90=140
180-140=40
Answer:
40 degrees
Step-by-step explanation:
so in order to find this we first off know that every triangle's inside angles are equal to 180 degrees total.
so if we take that <A is equal to 90 degrees
then we see that the outside of <C is equal to 130 and line BCD is a confirmed straight line
then each line is equal to 180 degrees so we subtract 130 from 180 in order to find the inside angle of C so that would equal 50
so now that we know <A=90
and <C=50
then we add those two together and that equals 140 degrees
and so there is only one more angle which is <Z
so we subtract 140 from the total amount of 180 degrees in the triangle
leaving us with <Z=40 degrees
what is the median in the box plot ? 50 60 70 80 90 100
Answer:Median
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Y=2x
X = -y + 6
Answer:
(2, 4 )
Step-by-step explanation:
Given the 2 equations
y = 2x → (1)
x = - y + 6 → (2)
Substitute x = - y + 6 into (1)
y = 2(- y + 6) ← distribute
y = - 2y + 12 ( add 2y to both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Substitute y = 4 into (2) for corresponding value of x
x = - 4 + 6 = 2
solution is (2, 4 )

Joe sold a total of 10 baked goods. Each cookie costs $1.25 and each brownie costs $2.50. Joe made $20 at the bake sale. How many cookies did Joe sell?
Answer:
16 cookies
Step-by-step explanation:
20/1.25=16
You take the total cost and divide it by the individule cost
Answer: Joe sold 5 cookies
Step-by-step explanation:
If you do the multipaction you will know that 2.50 x 5 = 12.50 and then you would have 5 more baked goods so then you would multiply 1.50 x 5 which equals 7.5 which when you add together equals a total of 20

Which relationships describe angles 1 and 2?
Select each correct answer.
vertical angles
supplementary angles
complementary angles
adjacent angles
Two lines intersecting in a right angle with a ray splitting the third quadrant with one labeling the left angle and two labeling the angle right of the ray
It's multiple answers. If you don't know it Please don't answer!!
Answer:
I think adjacent angles are the vertical angles but supplementary angles are 2 angles that combine to equal 180 degrees and complementary angles are 2 angles that add up to 90 degrees so the right angle with a ray splitting it is a complementary angle.
