Mrs. Bowman spent $110 to rent a popcom machine for the school
carnival and $75 to buy popcorn, oil, and other supplies. If she sold
263 bags of popcorn for $1.50 each, how much money did she make after paying for the machine and the supplies?
Answer:
200 minutes I am getting poi tea yayyyy
Answer:
$209.50
Step-by-step explanation:
First, find how much she made selling the popcorn:
263(1.5)
= 394.50
Then, find how much she spent on supplies and the machine:
110 + 75
= 185
Subtract the expenses from the profit:
394.50 - 185
= $209.50
Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided. 4(3 - 2x) = 15
Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
The correct answer is: -3/8
Write the algebra expression: six times the sum of four and a number
Answer:
6(4+x)
Step-by-step explanation:
Answer:
6(x+4)
Step-by-step explanation:
We want to write an algebraic expression for "six times the sum of four and a number"
Let's break this down.
The sum of four and a number:
The words "sum" indicates addition. We can call " a number" x, since it is unknown.
So, the sum of four and a number is: (x+4).
Six times:
The word "times indicates multiplication. We are multiplying six and the sum of four and a number.
So, we have: 6(x+4)
The algebra expression for "six times the sum of four and a number" is 6(x+4)
There are 7 more sweaters than shirts in the drawer. There are 15 sweaters and shirts in the drawer in all. How many shirts are there in the drawer? Let S represent the number of shirts. Which equation represents the situation
Answer:
7 + 2s = 15
4 shirts
Step-by-step explanation:
Let's say w denotes sweaters and s denotes shirts.
Since there are 7 more sweaters than shirts:
w = 7 + s
There are a total of 15 sweaters and shirts in all, so:
w + s = 15
Substitute 7 + s in for w in the second equation:
w + s = 15
7 + s + s = 15
7 + 2s = 15
Solving for s:
7 + 2s = 15
2s = 15 - 7 = 8
s = 8/2 = 4 shirts
Thus, the equation is 7 + 2s = 15, and there are 4 shirts.

The requried value of the unknowns in the function is given as a = 4 and b = 3.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
As mentioned in the question,
For even function table is given,
x ⇒ -2, 0, 2, 3
f(x) ⇒ 4 5 a 7
For even function,
f(x) = f(-x)
From table,
f(2) = f(-2) = 4
So, a = 4
For odd functions,
f(-x) = -f(x) [f(-x) ≠ f(x)]
f(-2) = -f(2)
b = 3, [f(2) = -3 from table]
Thus, the requried value of the unknowns in the tables is given as a = 4 and b = 3.

Hugh bought some magizines that cost 3.95 each and some books that cost 8.95 each. He spent a total of 47.65.If Hugh bought 3 magazines,how many books did he buy
Answer:
4 books
Step-by-step explanation:
We are told that: Hugh bought some magazines that cost 3.95 each
Hugh bought 3 magazines.
Hence, total cost of magazines = 3 magazines × 3.95
= 11.85.
Total cost of magazines = 11.85
From the question, we know that, the total amount Hugh spent = 47.65
Hence, The total cost for books =
Total amount spent - Total cost of magazines
= 47.65 - 11.85
= 35.80
Therefore, the total cost of books = 35.80
We are told in the question that the cost of books is 8.95 each or 8.95 per book.
Hence, the number of books that Hugh bought is calculated as :
35.80/8.95
= 4 books
Therefore, Hugh bought 4 books
Express 4 tickets for $25 as a unit rate
Unit rate is the amount it costs for 1.
Divide total cost by number bought:
25/4 = 6.25
Unit price = $6.25 per ticket

Allison wants to buy a skirt that has a regular price of $30. The skirt is on sale for 1/5 off the regular price. Allison has a coupon that will take 1/10 off the sale price. There is no sales tax on clothing. If Allison pays with a $50 bill, how much change will she receive? (Note: Express the answer as dollars.cents.)
Answer:28.4
Step-by-step explanation:
The amount of change received is $28.4.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Regular price = $30
Selling price = (30 - 1/5 x 30) = 30 - 6 = $24
Coupon off = 1/10 x 24 = 2.4
The amount the shirt was bought.
= 30 - 6 - 2.4
= 30 - 8.4
= 21.6
The change was received.
= 50 - 21.6
= $28.4
Thus,
$28.4 is received as changed.

If a and B are the zeros of the quadratic polynomial f(x) = x2- 5x + 4 find the value of 1/a+1/b-2ab
Answer:
-27/4Step-by-step explanation:
Given the quadratic polynomial given as g(x) = x²- 5x + 4, the zeros of the quadratic polynomial occurs at g(x) = 0 such that x²- 5x + 4 = 0.
Factorizing the resulting equation to get the roots
x²- 5x + 4 = 0
(x²- x)-(4 x + 4) = 0
x(x-1)-4(x-1) = 0
(x-1)(x-4) = 0
x-1 = 0 and x-4 = 0
x = 1 and x = 4
Since a and b are known to be the root then we can say a = 1 and b =4
Substituting the given values into the equation 1/a+1/b-2 ab , we will have;
= 1/1 + 1/4 - 2*1*4
= 1 + 1/4 - 8
= 5/4 - 8
