=============================================
U = set of natural numbers less than 8
U = {1,2,3,4,5,6,7,8}
G = set of even integers less than 10
G = {..., -4, -2, 0, 2, 4, 6, 8}
Circle the items in G that are also in set U. Those items are {2,4,6,8}
Then go back to set U = {1,2,3,4,5,6,7,8} and erase 2,4,6,8 to be left with {1,3,5,7}
The complement of a set is everything that isn't in a given set. Think of it as the opposite.

2. Mr. Leu is thinking about getting a new cell phone data plan. He looks at two
different cell phone companies US Cellular and Verizon. US Cellular has a plan
where he pays $36 per month and $12 per GB of data he uses per month.
Verizon has a plan that charges $54 per month and $10 per GB of data he uses
per month. How many GB of data would he have to use in a month to make both
plans cost the same? Which plan would you recommend he use?
Answer:
he would have to use all of it and then $16 more to make both plans cost the same. I think he should go with US Cellular
Step-by-step explanation:
just because
if 1 and -3 are the zeroes of the polynomial xcube - axsquare - 13x + b find the values of a and b
Step-by-step explanation:
f(x) = x³ - ax² - 13x + b.
f(1) = 1³ - a(1)² - 13(1) + b = 0
=> 1 - a - 13 + b = 0, b - a - 12 = 0.
f(-3) = (-3)³ - a(-3)² - 13(-3) + b = 0
=> - 27 - 9a + 39 + b = 0, 12 - 9a + b = 0.
Therefore, b - a - 12 = 12 - 9a + b. 8a = 24, a = 3.
=> b - (3) - 12 = 0, b = 15.
Evaluate each expression.

If s ( x ) = 2 - x² and t ( x ) = 3x, what is s ( t ( -7 ) )?
Answer:
- 439
Step-by-step explanation:
s ( x ) = 2 - x² t ( x ) = 3xs ( t ( -7 ) ) = ?--------------------------
t (-7) = 3 * ( -7 ) = -21s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439s ( t ( -7 ) ) = -439Brain can type 50 words per minute. He needs to finish typing his 700-word essay and already has 375 words typed. Write and solve an equation to determine the number of minutes (m) that it will take Brain to finish writing his essay. ( round your answer to the nearest tenth)
Answer:
Step-by-step explanation:
Every minute he types 50 words, so in 700 he types for 14 min. The next step is that there 375 words already done. So you take 700 and and subtract it by 375 and that is 7. Hope It helped you out
I NEED HELP PLEASE !!!
Answer:
real numbers, including the boundary lines
Step-by-step explanation:
The inequality symbols in this system both include the "or equal to" case, so the boundary lines of the "shaded area" are part of the solution set.
Ordinarily, weight is a continuous variable, so we presume the weights of almonds and cashews may be any real number. The problem statement gives no clarity in that regard, so it is entirely possible that the given nuts will only be delivered in packages with integer weights.
Based on our presumption, the solution set is best described as below.
_____
Additional comments
Each inequality gives rise to a "shaded region," as shown in the second attachment. The solution set will be the doubly-shaded region, limited to the first quadrant. (Quantities of nuts cannot be negative.) Strictly speaking, the answer choices are all incorrect.
If f(x) = 4x + 8 and g(x) = \/x + 4,
what is (fºg)(12)?
Answer: 24
Step-by-step explanation:
(fºg)(12) would be f(g(12))
Plug in 12 for g(x) = square root of (12+4) = 4
Plug 4 in f(x)
f(4) = 16 + 8

647,224 likes/8 hours to calculate a u it rate for likes per minute, what new ratio would you create?
Answer:
the new ratio is 1348 likes per min.
Step-by-step explanation:
given:
647,224 likes/8 hours
find:
calculate a unit rate for likes per minute
= 647,224 likes x 1 hour
8 hours 60 min
= 1348.33
therefore,
the new ratio is 1348 likes per min.

Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hours and sold cars worth $120,000. How much did he make last month?
Answer:
$6520
Step-by-step explanation:
salary = hourly rate * hours + 5% of sales
salary = $13/hour * 40 hours + 0.05 * $120,000
salary = $520 + $6000
salary = $6520
Missi designed a stained glass window and made a scale drawing using centimeters as the unit of measurement. She originally planned for the length of the window to be 44 in. but decided to change it to 48 in. If the length of the window in her scale drawing is 4 cm, which statement about the change of scale is true?
One cm represented 11 in. in the first scale, but now 1 cm represents 12 in. in the second scale.
One cm represented 44 in. in the first scale, but now 1 cm represents 48 in. in the second scale.
One cm represented 1 in. in the first scale, but now 1 cm represents 1 in. in the second scale.
One cm represented 12 in. in the first scale, but now 1 cm represents 11 in. in the second scale.
Answer:
A. One cm represented 11 in. in the first scale, but now 1 cm represents 12 in. in the second scale.

Aisha has 3 pizzas. She is serving each person at a party 14 of a pizza. How many people can she serve at the party? Use the number line to help you solve the problem.[ Please help TwT]
Given:
Aisha has 3 pizzas.
She is serving each person at a party 1/4 of a pizza.
To find:
The number of people she can serve at the party.
Solution:
Let the number of people be x.
Number of pizzas is 3. So, each person get [tex]\dfrac{3}{x}[/tex] part of pizza.
It is given that each person get 1/4 of a pizza.
[tex]\dfrac{1}{4}=\dfrac{3}{x}[/tex]
Using cross multiplication, we get
[tex]1\times x=3\times 4[/tex]
[tex]x=12[/tex]
Therefore, the number of persons in 12.
Now, divide the number line in four equal parts between each pair of consecutive integers.
Then, count the marked points from 0 to 3 excluding 0. These points represent number of persons.

Answer:
h = (A - 9)/6
Step-by-step explanation:
Step 1: Define
A = b² + 2bh
b = 3
Step 2: Substitute
A = (3)² + 2(3)h
Step 3: Evaluate and solve for h
A = 9 + 6h
A - 9 = 6h
