A sales associate at a computer electronics store
is given a choice of two different salary plans.
One plan pays a weekly salary of $180 with a
commission of $30 for every computer sold. The
other plan pays no salary but offers $75
commission on each computer sold. How many
computers must the sales associate sale to make
the same amount of money under both plans?
Answer:
the sales associate has to sell 4 computers to make the same amount of money under both plans
Step-by-step explanation:
y=money
x=computers sold
Plan 1: y=30x+180
Plan 2: y=75x
75x=30x+180
45x=180
x=4

The price of a DVD is 24.00 plus 8%tax. What is the total Price on this DVD in dollars and cents?
Answer: $25.92
Step-by-step explanation: Using proportions, I found what 8% of 24 is. 8/100 = x/24, as shown in the photo. 8 x 24 = 192. Divide by 100 for 1.92 and that is the tax. Add 1.92 to the original of 24 to get $25.92

Which series of transformations will move the triangle in quadrant 1 onto the similar triangle in quadrant three?
Answer:
Its D if you think about it
Step-by-step explanation:in your mind move the triangle on the top right down 6 units and then turn your triangle 90 degrees counter clockwise (quick maths)
The only transformation that will move the triangle in quadrant 1 onto the similar triangle in quadrant three is;
Option D; translation 6 units down and rotation 90° counterclockwise
The y-coordinate of the right angle vertex of the triangle in quadrant 1 is y = -2. Meanwhile the y-coordinate of the same right angle point of the triangle in quadrant 3 is y = -4.
Thus, for the triangle in quadrant 1 to be on the same level with that in quadrant 3, we need to translate the triangle in quadrant 1 downwards by 6 units.
Now, since we want to map this newly translated triangle to the one in quadrant 3 and as such we need to rotate it 90° counterclockwise

jada earned $50 babysitting and plans to use the money to go to the fair l.admission to the fair is $5 and each ride is $2.50.while at the fair she buys a funnel cake for $3.what is the maximum number of rides jada can ride?
Answer:
The maximum number of rides is 16
Step-by-step explanation:
She has a total of $50 and spends $3 for the cake and $5 for admission. She has to spend $2.50 for every ride.
Your equation would be set up as:
$50=$5+$3+$2.50x
You would combine like terms and get
$50=$8+$2.50x
Subtract the $8 from $50 and you get
$42=$2.50x
Divide each number by 2.50 and you get
16.8=x, you cannot have a decimal as an answer since she cannot ride eight tenths of a ride so the maximum number of rides is 16

A new amusement-park ride that lasts 1 minute can have up to 1200 riders per hour. How many riders can ride per minute?
Answer:
20 riders can ride per minute.
Step-by-step explanation:
The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.
The reasoning behind this is:
There are 60 minutes in an hour.
If the park ride lasts a minute, then the ride can have 60 rides per hour.
The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.
1200 ÷ 60 = 20.

It can be concluded that, the statement made by the student - multiply the area of the base times the height is correct method to find the volume of box.
What is the volume of a Cuboid?
The volume of a cuboid is given by -
V = L x B x H.
where -
L is the length
B is the breadth
H is the height
Given is a statement made by a student who says - To find the volume of a box that has a 19 by 22 base and 27 layers, I multiply the area of the base times the height.
Since the dimensions of the base represent a rectangle, We can place 27 layers over it one after the another, the resulting figure will be a cuboid, such that the height of the cuboid will 27 units. The volume of the box will be -
Area of its base x 27
Or we can write -
19 x 22 x 27
11286 units³

What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?
Someone please help me
Answer & Step-by-step explanation:
When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:
[tex]y=mx+b\\\\[/tex]
m is the slopeb is the y-intercept, which is the value of y when the value of x is zerox and y are the corresponding coordinate points (x,y)[tex]6x-5y=15[/tex]
Solve for y. Subtract 6x from both sides:
[tex]6x-6x-5y=15-6x\\\\-5y=-6x+15[/tex]
Divide both sides by -5:
[tex]\frac{-5y}{-5} =\frac{-6x}{-5} +\frac{15}{-5} \\\\y=\frac{6}{5}x-3[/tex]
The slope is [tex]\frac{6}{5}[/tex].
Now you need to make an equation in point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
m is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinate pointsInsert known values:
[tex]y-4=\frac{6}{5}(x-5)[/tex]
You can use this equation, or you can convert to slope-intercept form by solving for y:
Use the distributive property:
[tex]y-4=\frac{6}{5} x-6[/tex]
Add 4 to both sides:
[tex]y-4+4=\frac{6}{5}x-6+4\\\\ y=\frac{6}{5}x-2[/tex]
:Done
The equation of the perpendicular line is [tex]y = \frac 65x - 2[/tex]
The equation of the line is given as:
[tex]6x -5y = 15[/tex]
Start by calculating the slope (m) of the line as follows:
[tex]6x -5y = 15[/tex]
Subtract 6x from both sides
[tex]-5y = 15 - 6x[/tex]
Divide both sides of the equations by -5
[tex]y = -3 + \frac65x[/tex]
Rewrite as:
[tex]y = \frac65x-3[/tex]
For a linear equation, y = mx + b, the slope of the line is m
So, the slope is:
[tex]m = \frac65[/tex]
The equation of the line is said to be parallel to the above equation
So, the slope of the line is:
[tex]m = \frac65[/tex]
The line is said to pass through point (5,4).
So, the equation of the line is:
[tex]y = m(x - x_1) +y_1[/tex]
This gives
[tex]y = \frac 65(x - 5) +4[/tex]
Expand
[tex]y = \frac 65x - 6 +4[/tex]
[tex]y = \frac 65x - 2[/tex]
Hence, the equation of the line is [tex]y = \frac 65x - 2[/tex]
