Determine the percentage of off-campus students
From the above table, we have that:
[tex]Off-Campus = 182[/tex]
[tex]Total\ Surveyed = 400[/tex]
The percentage is then calculated as follows;
[tex]\%Off-Campus = \frac{Off-Campus}{Total-Surveyed} * 100\%[/tex]
[tex]\%Off-Campus = \frac{182}{400} * 100\%[/tex]
[tex]\%Off-Campus = 0.455 * 100\%[/tex]
[tex]\%Off-Campus = 45.5\%[/tex]

At a sale, dresses were sold for 95% of their original price. If the dresses originally cost $200 each, how much did a dress cost on sale?
Turn the percentage into a decimal.
95% / 100 = 0.95
Multiply.
200 * 0.95 = 190
Subtract.
200 - 190 = $10
Therefore, the dress costs $10 on sale.
Best of Luck!
Answer: The answer is 190.
Kirima is building a wall for her snow fort. She first makes a firm base out of snow, and then piles uniformly sized blocks of snow in a brick-like pattern. She has a maximum height for this wall in mind, and she wants to figure out how many blocks can be stacked vertically in her wall while remaining below this maximum. So, she constructs the expression 0.4x + 0.6 to measure the height of her wall, where all constants represent measurements in meters. Which of the following statements are true? Select all that apply. 0.4 represents the height of the wall. 0.4 represents the height of the base. 0.4 represents the height of each block. 0.6 represents the height of the wall. 0.6 represents the height of the base. 0.6 represents the height of each block.
Answer:
The correct option is;
0.4 represents the height of each block
Step-by-step explanation:
The information given are;
Kirima first builds a firm base of a given height
Kirima is building her wall using uniformly sized bricks
the height of the wall she is building depends on the number of blocks stacked to form the wall
Therefore, variable that depends on other variable, which is the dependent variable, y, is the height of the wall
The independent, which determines the value of the dependent variable is the number of blocks added, x
The gradient of the equation is the height of each block = 0.4
The y-intercept is the starting value, which is the firm base of dimension, 0.6
Therefore, 0.4 represents the height of each block.

[tex]\huge\boxed{\sf a = -12 , b = 8}[/tex]
Step-by-step explanation:
Given polynomial is:
[tex]f(x) = ax^3+ b^2 + 3x + 4[/tex]
[tex]\rule[225]{225}{2}[/tex]
First factor is (x-1)
Let x - 1 = 0 => x = 1
Putting this in the above polynomial
[tex]f(1) = a(1)^3 + b(1)^2 + 3(1) + 4[/tex]
Given that it's remainder is 3
[tex]3 = a + b + 3 + 4[/tex]
[tex]3 = a + b + 7[/tex]
Subtracting 7 to both sides
[tex]-4 = a + b\\OR \\[/tex]
a + b = -4 -------------------------- (1)[tex]\rule[225]{225}{2}[/tex]
Second Factor is 2x + 1
Let 2x + 1 = 0 => x = - 1 / 2
Putting in the above polynomial
[tex]f(-\frac{1}{2} ) = a (-\frac{1}{2} )^3 + b (-\frac{1}{2} )^2 + 3 (-\frac{1}{2} ) + 4[/tex]
The remainder is 6
[tex]6 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2} + 4\\6 - 4 = -\frac{a}{8} + \frac{b}{4} - \frac{3}{2}\\2 = \frac{-a + 2b -12 }{8} \\-a + 2b - 12 = 16\\-a + 2b = 16 + 12\\[/tex]
-a + 2b = 28 --------------------------------(2)[tex]\rule[225]{225}{2}[/tex]
Adding both equations
a + b - a + 2b = -4 + 28
3b = 24
Dividing both sides by 3
b = 8
[tex]\rule[225]{225}{2}[/tex]
Putting b = 8 in Equation (1)
a + 8 = -4
a = - 4 - 8
a = -12

what is the answer h+6\5=2
Answer:
h = 4/5
Step-by-step explanation:
h + (6/5) = 2
h = 2 - (6/5)
h = (10/5) - (6/5)
h = (10-6)/5
h = 4/5
Check:
(4/5) + (6/5) = 2
10/5 = 2
The solution to the equation h + 6/5 = 2 is h = 4/5.
Given is an equation h + 6/5 = 2, we need to solve for h,
To solve the equation h + 6/5 = 2, we need to isolate the variable h on one side of the equation.
Let's begin by subtracting 6/5 from both sides of the equation to get rid of the term on the left side:
h + 6/5 - 6/5 = 2 - 6/5
Simplifying the equation:
h + (6/5 - 6/5) = 2 - 6/5
The term (6/5 - 6/5) is equal to 0, so we have:
h + 0 = 2 - 6/5
Simplifying further:
h = 2 - 6/5
To combine the fractions on the right side, we need a common denominator, which in this case is 5.
We can convert the whole number 2 into a fraction with a denominator of 5:
h = (2 x 5)/5 - 6/5
This becomes:
h = 10/5 - 6/5
Now we can subtract the fractions:
h = (10 - 6)/5
Simplifying:
h = 4/5
Therefore, the solution to the equation h + 6/5 = 2 is h = 4/5.

Answer:
3(3) + 0.75(2) = (3 + 0.75)x
Step-by-step explanation:
The cost per pound of the mixture is the total cost divided by the total weight.
3 lb granola at $3 per lb has a cost of 3(3)
0.75 lb of raisins at $2 per lb has a cost of 0.75(2)
The total cost is 3(3) + 0.75(2)
The mixture has an unknown cost per lb, so we call it x.
When you multiply the cost per lb of the mix by the total weight, you get the total cost.
Total weight of mix: 3 + 0.75
Cost per lb of mix: x
Total cost of mix: (3 + 0.75)x
Above, we know the total cost is 3(3) + 0.75(2)
We set these two amounts equal to get our equation.
3(3) + 0.75(2) = (3 + 0.75)x
Answer: 3(3) + 0.75(2) = (3 + 0.75)x

What is the probability of choosing a number 1 - 10 that is
greater than 5 or even?
Answer:
70%
Step-by-step explanation:
So, first, our set of choices is 10. This means that there are 10 choices.
We want a number that is greater than 5 or even. Thus, let's mark down all of our choices.
Numbers greater than 5 are:
6, 7, 8, 9, and 10.
Even numbers are:
2, 4, 6, 8, 10.
However, we already counted 6, 8, and 10 previously, so we'll ignore that.
All in all, the following numbers will satisfy our requirements:
2, 4, 6, 7, 8, 9, and 10.
This is 7 out of 10 numbers.
Therefore, our probability is:

A retailer sold a vacuum cleaner for 40% below its marked price. The sale price was 50% above the cost to the retailer. What is the ration of marked price to cost?
Answer:
10 : 9
Step-by-step explanation:
Given that a retailer sold a vacuum cleaner for 40% below its marked price.
Let the marked price = P
40% below = (100 - 40)P/100
Sale price = 60P/100
Sale price = 0.6P
The sale price was 50% above the cost to the retailer.
That is, cost price = (100 + 50)0.6P/100
Cost price = (150)0.6P/100
Cost price = 1.5 × 0.6P
Cost price = 0.9P
What is the ratio of marked price to cost?
The ratio will be = P/0.9P
Multiply both the numerator and denominator by 10
Ratio = 10 : 9

The formula is 4x+3x+2x=180.
x= 20
a= 40
b= 80
c= 60
Step-by-step explanation:
The expression is the angle measurments equaled to 180 degrees because they all make up a straight line (180 degrees).
You then find the other angle measurments by identifying the verticle angles.
For example, 3x= 60 degrees. Therefore angle C= 60 because it is verticle to 3x

Mary and Jane have $48 to share in the ratio 3:5. How much did each girl 2 points
receive? (SHOW WORKING)
Answer:
Mary- $18
Jane- $30
Step-by-step explanation:
Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.
x(3+5) = $48
3x + 5x = $48
8x = $48
8x/8 = $48/8
x = $6
3($6):5($6) = $18:$30
Answer:
Mary = $18
Jane = $30
Step-by-step explanation:
The first thing you need to do is find out how much each part is. To do that you need to add each side of the ratio together (3 + 5 = 8). THen you set up an equation showing the 8 parts * x = 48 and solve for x.
8x = 48
x = 6 <-- Value of each part
Now you multiply the 6 by the number on each side of the ratio,
Mary = 3 * 6 = 18
Jane = 5 * 6 = 30
The above is your answer.
