A town's population is 33,600. About 125 people move out of the town each month. Each month, 150 people on average move into town. A nearby town has a population of 35,000. It has no one moving in and an average of 150 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question Which equation models the situation? OA. 150m + 125m + 35,000 = 33,600 + 150m OB. 150m - 125m + 35,000 = 33,600 - 150m O C. 150m - 125m +33,600 = 35,000 - 150m OD. 150m + 125m +33,600 = 35,000 + 150m

I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell? CAN SOMEONE ANSWER IT PLZ
9514 1404 393
Answer:
12 muffins15 cookiesStep-by-step explanation:
Often, you can work these problems in your head.
If you sold all cookies, your revenue would have been 27×3 = 81. It was 129-81 = 48 more than that. Each muffin generates 4 more revenue than a cookie dies, so there must have been 48/4 = 12 muffins. The 27-12 = 15 were cookies.
You sold 15 cookies and 12 muffins.
__
If you let a variable represent the most expensive item (m for muffins), then you can write an equation for the revenue. You may recognize that some of the steps in the solution match the "verbal" solution above.
3(27 -m) +7m = 129
4m +81 = 129
4m = 129 -81 = 48
m = 48/4 = 12 . . . muffins
27-12 = 15 . . . cookies

An aquarium in the shape of square will hold 25 gallons of water. If the volume is 3.375 cubic ft., find the length of one side?
Answer: The length of one side = 1.5 feet
Step-by-step explanation:
GIven: The shape of aquarium is square ( in 3d its cube).
Its volume = 3.375 cubic ft
Volume of cube = [tex](side)^3[/tex]
i.e. side = [tex](Volume)^{\dfrac13}[/tex]
Now, Side of aquarium = [tex](3.375)^{\frac13} =(1.5^3)^{\frac13} =1.5[/tex] [[tex]1.5^3=3.375[/tex]]
Hence, the length of one side of aquarium = 1.5 feet

Which table shows a proportional relationship between x and y?
x 2 3 5 6
y 3 4 7 9
x 1 5 8 10
y 15 75 120 150
x 4 6 8 10
y 6 8 10 12
x 3 9 10 15
y 1 3 4 5
Answer:
The third table.
Step-by-step explanation:
To have a proportional relationship there must be a constant rate of change
6-5 / 9-7 = 1 /2
5-3 /7-4 = 2/3
these are different so this is not a proportional relationship
10-8 /150-120 =2/30
8-5 /120-75 =3/45
these are different so this is not a proportional relationship
10-8 /12-10 =2/2 =1
8-6 /10-8 =2/2= 1
These are the same therefore it is proportional

A really tough trivia quiz has 50 multiple-choice questions, each with four possibleanswers. Use a normal approximation to calculate the probability of randomly guessing the correct answers for at least half of the questions.
Answer:
0.00004
Step-by-step explanation:
Given that:
n = 50
Number of options = 4 ; 1 is the correct answer
Hence ;
p = 1/4 = 0.25
Using normal approximation :
Mean (m) = np = 50 * 0. 25 = 12.5
Standard deviation (s) = √(n*p*q)
q = 1 - p = 1 - 0. 25 = 0.75
s = √(50*0.25*0.75) = 3.062
At least half the question :
Half the question = 1/2 * 50 = 25
P(X ≥ 25) = P(X ≥ 24.5)
(x - m) / s
P(X ≥ 24.5) = (24.5 - 12.5) / 3.062
= 12 / 3.062
= 3.919
P(Z ≥ 3.919) = 0.00004 (Z probability calculator)

The cost of a compact disc is $18. Mrs. Meridth bought 3 discs and received a 15% discount. If the sales tax is 8.8%, find the total price. Show each step.
Answer:
$49.572
Step-by-step explanation:
Given that :
Cost per disc = $18
Number of disc purchased = 3
Discount received = 15%
Sales tax = 8%
Original cost : cost per dic * number purchased
Original cost = $18 * 3 = $54
Discounted price = (100 - 15)% * $54
Discounted price = $45.9
Sales tax :
(100 + 8)% of $45.9
108% * $45.9
= $49.572
Total price = $49.572

The side of a square measures (4x − 7) units.
Part A: What is the expression that represents the area of the square? Show your work to receive full credit. (4 points)
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
(10 points)
Answer:
Part A: 16x^2 -56x+49
I'm not quite sure on Part B and C though, sorry :/.
Step-by-step explanation:
To find the expression we need to solve (4x-7)•(4x-7)
4x•4x = 16x^2
4x•-7= -28x
-7•4x= -28x
-7•-7=49
Combine alike terms
16x^2-56x+49

V/8=2
Find the value of V?
Answer:
16
Step-by-step explanation:
Basic Algebra, isolate V.
Do the opposite equation to get V on its own.
Because it is V/8, multiply both sides by 8 to get 8 on its own (if you wanted to move v over you would divide)
[tex]\frac{v}{8} =2[/tex]
[tex]v =2*8[/tex]
[tex]v =16[/tex]
A 9-pound bag of sugar is being split into containers that hold 2/3 of a pound. How many containers will the 9-pound bag create?
Answer: below
Step-by-step explanation: You simply need to divide the total amount of sugar (9 lbs) by the amount that you put into each bag (2/3 lb). This expression looks kind of ugly in this form, so let's instead multiply 9 by the reciprocal of 2/3, which in this case is 3/2. The reciprocal of any number is just 1 divided by the number.
Answer:
12
Step-by-step explanation:
Each 3 pounds will need 4 containers
