Zymirah earns 5% commission on all sales at a jewelry store plus $10 an hour. Yesterday she sold $3,200 in merchandise and earned a total of $240. How many hours does she work?
Answer:
8 hours
Step-by-step explanation:
Given data
Commission= 5%
Sales= $3,200
Total earnings= $240
Let us find the amount in commission earned
=5/100*3,200
=0.05*3,200
=$160
Hence 240-160=$80
$80 is the amount earned yesterday
we are told that per hour is $10
Hence $80 will be earned for
=80/10
=8 hours
A line passes through (0, -1.8) and has a slope of -3. Write an equation of the line.
Answer:
y=-3x-1.8
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1.8)=-3(x-0)
y+1.8=-3(x)
y+1.8=-3x
y=-3x-1.8

A package of Little Bites dog cookies costs $9.20. Which equation can be used to find the total cost, c, of p packages of dog cookies?
Answer:
c=9.20p
Step-by-step explanation:
cost is what you're solving for so that goes on the outside. each package costs 9.20 so you multiply however many packages by that number when finding the cost.

Step-by-step explanation:
A spinner with 20 equal-sized sections has 5 red, 10 blue, 3 green, and 2 yellow sections. Ann pays $10 to spin the spinner. If she spins a yellow, she wins $20; if she spins green, she wins $15; otherwise, she loses.She plays the game twice. What is the expected payoff for her games?
Answer:
The expected payoff for Ann is that she loses the game
Step-by-step explanation:
The expected payoff for Ann is that she loses the game, this is because only 5 out of the 20 sections allow Ann to win money, this is only 25% of the spinner. Meaning that 75% of the spinner will cause Ann to lose the game. Rolling two times increases the odds that she will lose the game. Since the greatest probability is that Ann will land on a section that causes her to lose the game, then this is the expected payoff.

Answer: 72.32
Step-by-step explanation:
The line is 180 so
7x + 8x + 44.4 = 180
15x + 44.4 = 180
-44.4 = -44.4
15x = 135.6
divide both by 15
x = 9.04
So 8 * 9.04 = 72.32
Answer:
The answer is 72.32°
Step-by-step explanation:
So, since that is a straight line, we know that all of the angles add up to get 180° total. Using this knowledge, we can determine that 44.4 + 8x + 7x = 180°.
First, we need to find what x is to find the missing values. To do that, we have to set all the values, 44.4, 8x, and 7x equal to 180, because we know they add up to 180°.
44.4 + 8x + 7x = 180
Combine the like terms.
44.4 + 15x = 180
Bring the 44.4 over to the other side in order to get x alone by subtracting it from 180.
15x = 135.6
Divide both sides by 15 to get x completely alone.
x = 9.07
Now we have what x is, 9.07.
All you need to do now is substitute 9.07 into the place of x.
8(9.07) = 72.32
So now you know that the highlighted angle is 72.32°.
Using the equation y=kx what would be the proportionate equation if she worked 25 hours and made 150.00
Answer:
y = 6x
Step-by-step explanation:
Equation representing the relation between duration of work and earning is,
y = kx
Here, y = earnings
x = Working hours
k = Proportionality constant
By substituting the values in the given equation,
x = 25 hours
y = $150
150 = k(25)
k = 6
Therefore, equation modeling the situation will be,
y = 6x

What is the point-slope form of a line with slope 2 that contains the point
(1,3)?
Answer:
(y-3) = 2(x-1)
Step-by-step explanation:
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
(y-3) = 2(x-1)

Students sell 80% of the books at a book slae. They sell 48 books in all. How many books are at the book sale? Show your work.
Answer:
60 books were at the book sale
Step-by-step explanation:
Let
x = total books at the book sale
Percentage of books sold = 80% of x
= 80/100 * x
= 0.8x
Number of books sold = 48
Therefore,
0.8x = 48
Divide both sides by 0.8
0.8x / 0.8 = 48 / 0.8
x = 60 books
x = total books at the book sale = 60 books
Number of books unsold = Total books at the book sale - number of books sold
= 60 - 48
= 12
Number of books unsold = 12 books

Write the Equation of the line in fully simplified slope- intercept form
Answer:
y=-6/5x-2
Step-by-step explanation:
We are given points (5,-8) and (-5,4)
Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5
Y-intercept = b = (0,-2)
Final equation: y=-6/5x-2
Answer:
y=-6/5x-2
Step-by-step explanation:
y=mx+b
Its sloping downwards, so a negative slope.
two points: (-5,4) and (5,-8)
---------------------------------------------
so first find the slope.
y2-y1 / x2-x1 <= formula
so: -8-(4) / 5-(-5)
which becomes => -12/ 10
which is 6/5 the slope is 6/5
------------------------------------------
plug this into y=mx+b, where m is the slope
so: y=6/5x+b
------------------------------------------
obviously b is the y intercept, where the line meets y
the y intercept is -2
sooooooo final answer is
----------------------------------
y=6.5x+(-2)
-----------------------------------
Negative slope, so becomes y=6/5x-2
What are the cordinates of the point on the directed line segment from -3 -9 to 4 5 that partitions the segment into a ratio of 5 to 2
Answer:
[tex](x,y) = (2,1)[/tex]
Step-by-step explanation:
Given
Coordinate: (-3,-9) and (4,5)
Ratio= 5 : 2
Required
Determine the point at the segment
The coordinate of the point is calculated using:
[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]
Where:
[tex]m : n=5:2[/tex]
[tex](x_1,y_1) = (-3,-9)[/tex]
[tex](x_2,y_2) = (4,5)[/tex]
So, we have:
[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]
[tex](x,y) = [\frac{5 * 4 + 2 * -3}{5+2},\frac{5*5+2*-9}{5+2}][/tex]
[tex](x,y) = [\frac{14}{7},\frac{7}{7}][/tex]
[tex](x,y) = (2,1)[/tex]
The coordinate of the point is: (2,1)
An aeroplane is 528 ft directly above an automobile and starts east at the rate of 20 miles an hour at the same instant the automobile starts east at the rate of 40 miles an hour. How fast are they separating
Answer: 20 mph
Step-by-step explanation:
Given
The airplane is at a height of 528 ft with a rate of 20 mph
The automobile is also directing east at the rate of 40 mph
at this instant, they are separating by the relative velocity between them
[tex]\Rightarrow v_{rel}=40-20=20\ mph[/tex]

Sophia needs to know the area and perimeter of his property. The length of his property is 1/5 mile and the width is 3/8 mile. What is the perimeter of Sophia's property?
Answer:
See the answers below
Step-by-step explanation:
Given data
Length = 1/5mile
Width= 3/8 mile
The expression for the perimeter
P=2L+2W
Substitute
P=2*1/5+ 2* 3/8
P= 2/5+6/8
P= 16+30/40
P=46/40
P= 23/40 miles
Area= Length *Width
Area= 1/5* 3/8
Area= 3/40 square miles
