An amusement park charges $8 for parking in addition to $1.25 per ride ticket. Write an equation to represent the total cost to visit the amusement park, then find the number of rides a person can go on, if they have $30. Identify your variables.
Answer:
Amount of rides = (30 - 8)/1.25
Answer:
c = 8 + 1.25r
the unit used is dollars
r = the amount of ride tickets purchased
c = total cost
a person could could go on 17 rides with 30$
Step-by-step explanation:
To develop the equation:
1. first, you want your total cost on one side. That is c (c =)
2. second, you need to identify the variable that changes the cost in the equation. That would be the amount of ride tickets because it changes the total cost based on how many a person buys. (c = 1.25r)
3. third, you add the variable that never changes, which is the eight dollars for parking (c = 1.25r +8)
In order to solve for a specific amount of money, you plug in the amount in place of your total cost (c) variable. In this case, you would solve 30 = 8 + 1.25r
It would look something like this:
30 = 8 +1.25r
(subtract 8 from both sides)
22 = 1.25r
(divide each side by 1.25)
r = 17.6
(round down because you can't buy a ride ticket with only 60 cents)
and you're done!
hope that helps!
The ratio of students to teachers at a school is 19:1. At this school, there are 400 people (teachers and students). How many of these 400 people are students?
(enter the number only, without the unit)
Answer:
380
Step-by-step explanation:
First, figure out that in the ratio of 19 : 1, there are 20 people. 400 divided by 20 = 20. This means you have to multiply the number of students in the original ratio (19) by 20 to get the actual amount of students.
19 × 20 = 380 so there are 380 students.

C
Step-by-step explanation:
First, let us try the first on:
sqrt (5^2+4^2)=sqrt 41 so it can't be A
Second one:
sqrt (6^2+7^2)=sqrt 85, no
Third one:

During a field trip, 60 students are put into equal sized groups.
**Describe two ways to interpret 60 ÷5 in this context.
**Find the quotient.
Explain what the quotient would mean in each of the two interpretations you described.
NO WORK = NO CREDIT = REPORT
Thx for helpin <3 !
Answer:
The quotient would be 12.
Step-by-step explanation:
The first way to interpret it would be: 60 as the total amount of students, divided by 5 students per group which = 12 groups with 5 students in each.
The second way to interpret it would be: 60 as the total amount of students, divided into 5 groups which = 12 students in each group.

Answer: f(3) = g(3)
Step-by-step explanation:
ok so f and g are unknown numbers and 3 is equal to 3, since f and g are unknown they could be any number so that's why there the same.
Answer:
f(3) > g(3)
Step-by-step explanation:
add 3 into each equation.
f(x) = 4x^4 g(x) = 10 * 2^x
= =
f(3) = 4(3)^4 g(3) = 10 * 2³
Solve each equation.
f(3) = 4(3)^4 g(3) = 10 * 2^3
= =
f(3) = 12^4 g(3) = 20^3
= =
f(3) = 20,736 g(3) = 8,000
f(3) is greater than g(3)
f(3) > g(3)

Hopes this help
Answer: THE PROBABILITY OF DRAWING A YELLOW MARBLE IS 1/10
THE PROBABILITY OF DRAWING A RED MARBLE IS 5/18
Step-by-step explanation:
FIRST WE DIVIDE THE NUMBER OF YELLOW MARBLES WITH THE TOTAL AMOUNT OF MARBLE THAT IS 2(THE NUMBER OF YELLOW MARBLES)/20(THE TOTAL NUMBER OF MARBLES IN THE BAG)
SO 2/20=1/10
WHEREAS IN THE SECOND ONE, THE YELLOW MARBLES ARE ALREADY DRAWN SO 20-2=18 5(THE NUMBER OF RED MARBLES)/18(THE TOTAL NUMBER OF MARBLES)
SO 5/18
