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

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

Answer:
162 degrees
Step-by-step explanation:
Angles P and F are supplementary, so ...
3x^2 +12x = 180
x^2 +4x = 60
x^2 +4x -60 = 0
(x +10)(x -6) = 0
The useful value of x that makes this true is x=6.
The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:
∠S = 180° -18° = 162°

Step-by-step explanation:
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
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
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]

Caleb buys a two-pint bottle of juice for $4.48. What is the unit rate of the
cost of the juice per fluid ounce?
Answer:
0.14
Step-by-step explanation:
Not sure if this is what you are asking but, 2 pints is 32 ounces. So if you want juice per ounce then you divide 4.48/ 32 which gets you: 0.14. Sorry if this is not what your are looking for.

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
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)
