Answer:
Step-by-step explanation:
The new bike costs 180 dollars
Parents paid 40%
what is a percentage? per cent= divide by 100
parents paid 180 *40/100=180*0.4=72 dollars
Jennifer has to pay the rest
180-72=108
Answer:
$108
Step-by-step explanation:
You want to start by finding 40% of 180. When something says "of", you multiply! To make 40% in the correct format, move the decimal over to the right by two spaces, which leaves you with .40. As I said "of" means multiply, so you do .40 x 180, which = $72. This is the amount her parents paid, so you much subtract this from the total amount to find out what Jennifer paid. You do 180-72=$108. Jennifer paid $108!

8x – 3y = 5
3y = 2x + 1
Answer:
x = 1
y = 1
Step-by-step explanation:
this should be your answer
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
8x - 3y = 5 → (1)
3y = 2x + 1 → (2)
Substitute y = 2x + 1 into (1)
8x - (2x + 1) = 5
8x - 2x - 1 = 5
6x - 1 = 5 ( add 1 to both sides )
6x = 6 ( divide both sides by 6 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
3y = 2(1) + 1 = 2 + 1 = 3 ( divide both sides by 3 )
y = 1
solution is (1, 1 )

Find the 6th term 9 18 36
Answer:
I think the answer is 288.
Step-by-step explanation:
The rule seems to be multiplying the past number by 2. So, 9*2=18 and 18*2=36. If we continued that rule we would then get 72, 144, and the sixth term is then 288.
hope this helps :D
Answer:
Step-by-step explanation:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
[tex]a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288[/tex]

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day. Today, the balance in Lin's sister's account is -$2.67. In 14 days, Lin's sister will be paid $430 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $5.95 each day after this deposit is made? Explain or show your reasoning.
Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.
Step-by-step explanation:
Today, Lin's sister's balance is -$2.67
She gets charged $5.95 per day.
There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times
So her balance after 14 days will be:
Balance = -$2.67 - $5.95*14 = -$85.97
When she charges the $430 in the account, her balance will be:
Balance = -$85.97 + $430 = $344.03
So now she has a positive balance, which means that the bank does not charge her anymore.

In a high school stadium there are 750 seats. There are twice as many seats in the home
section as there are in the visitor section. Which system of equations could be used to
determine the number of seats in the home section, h, and the number of seats in the
visitor section, v, in the stadium?
PLEASE HELP HURRY PLEASEEE
Answer:
There are 250 home section and 2(250) = 500 visitor section.
Step-by-step explanation:
Let there are h number of seats in the home section and v is the number of seats in the visitor section.
h+v = 750 ...(1)
There are twice as many seats in the home section as there are in the visitor section.
v = 2h ...(2)
From equations (1) and (2).
h+2h = 750
3h = 750
h = 250
Hence, there are 250 home section and 2(250) = 500 visitor section.
lf p+q/s=9, q/p =4, and square q=6, what is the value of s?
Answer:
s=5
Step-by-step explanation:
The third equation implies that q=36.
Substitute for q in the second equation to get
36/p=4
Now solve for p
p/36=1/4
p=36/4=9
Solve the first equation for s.
s/(p+q)=1/9
s=(p+q)/9
Now substitute for q and p in this equation.
s=(9+36)/9=45/9=5
Johnny wrapped a piece of string around a can of soup. If the soup's diameter was 4 inches, how long was the string? Find the circumference
Answer:
12.56
Step-by-step explanation:
Formula is Pi* radius(squared) and since you aren't given the radius you can figure that out by dividing the diameter by 2 to get radius
Answer:
12.57 inches
Step-by-step explanation:
A piece of string wrapped around a can has the length of the circumference of the can.
circumference = pi * d
C = 3.14159 * 4 inches
C = 12.57 inches
GEOMETRY Holly can make an open-topped box out of a square piece of cardboard by cutting 3-inch squares from the corners and folding up the sides to meet. The volume of the resulting box is V = 3x^ 2 – 36x + 108, where x is the original length and width of the cardboard.
Factor the polynomial expression from the volume equation.
HINT: look for a GCF first!
Answer:
[tex]V(x)=3(x-6)(x-6)[/tex]
Step-by-step explanation:
Polynomial Factoring
The volume of a cardboard box is expressed as:
[tex]V(x)=3x^2-36x+108[/tex]
It's required to factor that expression.
First, factor out 3:
[tex]V(x)=3(x^2-12x+36)[/tex]
The expression in parentheses is a perfect square:
[tex]\boxed{V(x)=3(x-6)(x-6)}[/tex]
what is the amount of pieces in each color
Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78
