Help? A set of pens sells for $5.25 and costs $1.80 to make. Forty percent of the profit (the difference between the purchase price and the amount it costs to make) from each set of pencils goes to a school. If 1200 sets are sold, what is the amount of money that will go to the school?
I tried doing a question similar to this and I have no idea what I'm doing :,)
Answer:
$1656
Step-by-step explanation:
First you subtract 1.80 from 5.25. Then you find 40% of that, then multiply it by 1200 and you should have your answer.

If x = 12 units, y = 3 units, and h = 12 units, find the area of the parallelogram shown above using decomposition.
A.
108 square units
B.
180 square units
C.
144 square units
D.
216 square units
Answer:
The area is 144 square units
Step-by-step explanation:
The only two measurements that matter are x and h. Since both are 12, we multiply them by each other. 12 x 12 = 144
So the answer is 144 square units
In New York City, the cost to take a taxi can be represented with the equation y = .40x + 2.50, where x is the number of miles driven and y is the total cost. The cost of a taxi in San Francisco is shown in the table below.
Answer:
y = 0.45x + 2.85
Step-by-step explanation:
to solve we can first subtract the initial cost by taking the price at 0 miles and subtracting it from one of the higher numbers, we will go with $5.10 at 5 miles for this example
5.10 - 2.85 = 2.25
now we have the price for just the 5 miles separated from the initial cost, but we still need to figure out what each single mile is, so now we just divide by 5, one for each mile
2.25 / 5 = 0.45
so $0.45 is the cost to ride for one mile, and the initial cost is 2.85, now all we have to do is implement those numbers into a formula, since 0.45 is for each mile, it is multiplied by the miles, or x, so that will be put together below
0.45x
then we have the value to add to that, 2.85
0.45x + 2.85
and that is = to y, the cost to ride in a San Francisco taxi
The cost of a taxi in San Francisco is higher compared to New York and the equation of line is y = 0.75x + 2.85
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = 0.40x + 2.50 be equation (1)
where y represents the cost of the taxi in New York for x miles driven
Let the first point be P ( 0 , 2.85 )
Let the second point be Q ( 5 , 5.10 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 5.10 - 2.85 ) / ( 5 - 2 )
Slope m = 0.75
And , the equation of line for the cost of the taxi in San Francisco for x miles driven is given by
y - ( 2.85 ) = ( 0.75 ) ( x - 0 )
Adding 2.85 on both sides , we get
y = 0.75x + 2.85 be equation (2)
So , when x = 1 mile
y = $ 3.60
And , when x = 1 in equation (1) , we get
y = $ 2.90
Therefore , the cost of a taxi in San Francisco is higher compared to New York
Hence , the equation of line is y = 0.75x + 2.85 for the cost of taxi in San Francisco

A group of students were surveyed to find out if they like playing tennis or volleyball in PE class. The results are shown in the table:
Complete the table and answer the following questions.
a. What percentage of the total students surveyed like both
Volleyball and Tennis?
b. What is the probability that a student who does like
Volleyball does not like Tennis?
Using the probability concept, it is found that:
a) 41.67% of the total students surveyed like both Volleyball and Tennis.
b) There is a 0.1667 = 16.67% probability that a student who does like
Volleyball does not like Tennis.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
There is a total of 70 + 50 = 120 students, and x + 20 = 70 -> x = 50 like both sports, hence:
p = 50/120 = 0.4167.
41.67% of the total students surveyed like both Volleyball and Tennis.
Item b:
60 students like voleyball, and of those, 10 do not like tennis, hence:
p = 10/60 = 0.1667 = 16.67%.
There is a 0.1667 = 16.67% probability that a student who does like
Volleyball does not like Tennis.

The prism below is made of cubes which measure of a centimeter on one side. What is the volume?
Note: Figure is not drawn to scale.
A.
B.
C.
D.
Answer:
8 cm cubed
Step-by-step explanation:
Because that the cubes are well, cubes, all the sides are the same. If 1 side= 1, then the other ones are too. Once you look at the prism, you will notice that there are 8 cubes in total. Let's find the volume of 1 cube first:
The formula is:
w*h*l = v
1*1*1=1
The volume for 1 cube is 1 cm cubed.
1*8=8
The volume for the prism is 8 cm cubed.

One pumpkin weighs 7 lb 12 oz. A second pumpkin with 10 pounds 4 ounces. A pumpkin weighs 2 pounds 9 ounces more than the second pumpkin what is the total weight of all three pumpkins?
Answer: 30 lbs, 13 oz
This converts to 493 ounces
===============================================================
Explanation:
Pumpkin A weighs 7 lb, 12 oz. Let's convert that to ounces only
1 lb = 16 oz
7 lbs = 112 oz (multiply both sides by 7)
7 lbs, 12 oz = 112 oz + 12 oz .... add 12 oz to both sides
7 lbs, 12 oz = 124 oz
Pumpkin A's weight of 7 lbs, 12 oz is the same as 124 oz
-----------
Do something similar for pumpkin B
1 lb = 16 oz
10 lbs = 160 oz
10 lbs, 4 oz = 160 oz + 4 oz
10 lbs, 4 oz = 164 oz
Pumpkin B weighs 164 oz
-----------
Let's convert the "2 lbs, 9 oz" to ounces only
1 lb = 16 oz
2 lbs = 32 oz
2 lbs, 9 oz = 32 oz + 9 oz
2 lbs, 9 oz = 41 oz
So pumpkin C is 41 ounces heavier compared to pumpkin B
The weight of pumpkin C is 164+41 = 205 ounces
----------
We have these three weights in ounces only
Pumpkin A = 124 ozPumpkin B = 164 ozPumpkin C = 205 ozAdding those three ounces only weights leads to
124+164+205 = 493 ounces
The total weight of all three pumpkins is 493 ounces
Now let's convert back to the unit "pounds, ounces"
Divide that result over 16 since there are 16 ounces per pound
493/16 = 30.8125
Ignore the decimal portion. The 30 is the quotient which means 493-30*16 = 13 is the remainder.
In other words,
493/16 = 30 remainder 13
which leads to
493 ounces = 30 pounds, 13 ounces
--------------
As a check,
1 lb = 16 oz
30 lbs = 480 oz
30 lbs, 13 oz = 480 oz + 13 oz
30 lbs, 13 oz = 493 oz
The answer is confirmed.

Amelia works as a babysitter for an hourly wage of $8. Which equation represents the relationship between Amelia's total earnings (y) and the number of hours she works (x)?
1. 8y = x
2. y + 8 = x
3. y = 8x
4. y = x + 8
Answer:
3. y = 8x
Step-by-step explanation:
y = 8x
earnings (y)=$8×number of hours (x)
8 dollars is her hourly wage and that multiplied by the number of hours she works will give you her total earnings.
