a student cost for last semester at her community college was $2200. she spent $308 of that on books. what % of last semesters college costs was spent on books
Answer:
We conclude that 14% of last semester's college cost was spent on books.
Step-by-step explanation:
The cost spent at community college = $2200
The amount spent on books = $308
The % of last semesters college costs was spent on books can be determined using the formula
% spent books on = [308 / 2200] × 100
= 0.14 × 100
= 14%
Therefore, we conclude that 14% of last semester's college cost was spent on books.

Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
Perimeter
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
Area
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

Step-by-step explanation:
A company makes 140 bags.
21 of the bags have buttons but no zips.
25 of the bags have zips but no buttons.
45 of the bags have neither zips nor buttons.
How many bags have zips on them?
A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object. The total number of bags that have both zips and buttons is 49.
What is a set?A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that A company makes 140 bags. 21 of the bags have buttons but no zips. 25 of the bags have zips but no buttons. 45 of the bags have neither zips nor buttons.
Now, we can write the following things about the given condition,
Total number of bags, s = 140
Bags with Only zips, only Z = 25
Bags with only buttons, only B = 21
Bags with neither or them, Z'∩B' = 45
Now, the total number of bags that have both of them is,
Z∩B = s - only Z - only B - Z'∩B'
= 140 - 25 - 21 - 45
= 49
Hence, the total number of bags that have both zips and buttons is 49.

Which side is the hypotenuse in your diagram?
Answer:
the ten-inch side is the hypotenuse.
Step-by-step explanation:
[tex]a^{2}+ b^{2} =c^{2}[/tex]a= 6
b= 8
c= 10
use substitution to replace the variables in the equation, it should look like this:

A company that makes hair-care products had 6,000 people try a new shampoo. Of the 6,000 people,
36 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
% of the people had a mild allergic reaction,
Answer:
0.6% of the people had a mild allergic reaction.
Step-by-step explanation:
Given that:
Number of people who tried hair care products = 6000
Number of people who had reaction = 36
Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{36}{6000}*100[/tex]
Percent of people = 0.6%
Hence,
0.6% of the people had a mild allergic reaction.

Answer:
x=2
Step-by-step explanation:
First you put the equations in the form of y = mx + b
Then once they are like that it would look like:
y = -2x + 6
y = 3x - 4
So then you can set them equal to each other and it will look like this:
-2x + 6 = 3x - 4
Then you add 2x to both sides and get:
6 = 5x - 4
Next, add 4 to both sides and get:
10 = 5x
So then you will simplify by dividing both sides by 5 and getting:
2 = x
