Rahul is going to an amusement park. The price of admission into the park is $15, and once he is inside the park, he will have to pay $4 for every ride he rides on. How much money would Rahul have to pay in total if he goes on 7 rides? How much would he have to pay if he goes on rr rides?
Answers
Using a linear function, the costs are given as follows:
7 rides: $43.r rides: 15 + 4r.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The admission fee is the intercept.The cost per ride is the slope.Hence the cost for r rides is given by the following linear function:
C(r) = 15 + 4r.
The cost for 7 rides is given by:
C(7) = 15 + 4(7) = 15 + 28 = $43.

therefore,

THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.

A carnival game charges different prices for adults and children to play. Kids tickets are two dollars and adult tickets are five dollars. The carnival sold 36 tickets to this game and collected $135. Set up a system of equations that can be used to solve for the number of adult and children tickets sold for this game
Answers
Answer:
kids= 15
adults= 21
Step-by-step explanation:
Step one
let the number of kids be x
and adults be y
Kids tickets are two dollars and adult tickets are five dollars
The carnival sold 36 tickets to this game and collected $135
so the system of the equation is
2x+5y=135----------1
x+y=36---------------2
from 2 x= 36-y
put x= 36-y in 1
2( 36-y)+5y=135
72-2y+5y=135
collect like terms
3y=135-72
3y=63
divide both sides by 3
y= 63/3
y=21
put y= 21 in 2
x+21= 36
x=36-21
x=15
Solve -36 = j + 13 for j .
Answers
Answer:
J = -49
Step-by-step explanation:
Answer:
x=-49
Step-by-step explanation:
-36=j+13
first we need to get j by itself so we need to move 13 from the right side to left by subracting 13 from both sides.
-36-13=j+13-13
-49=j
since J is alone that is the answer

The length of a cell phone is 1.21.2 inches and the width is 4.64.6 inches. The company making the cell phone wants to make a new version whose length will be 1.141.14 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
Answer:
The width of the new phone will be 4.37 inches
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value.
The original length of a cell phone was L=1.2 inches and the original width was 4.6 inches.
A new version of the cell phone is to be released with proportional dimensions with respect to the original cell phone.
We are given the length of the new phone L'=1.14 inches. The ratio of the lengths is 1,2/1.14=1.053.
The new width should be W'=4.6/1.053=4.37 inches
The width of the new phone will be 4.37 inches

Find the equation of the line:

[tex]\displaystyle\\3=-\frac{1}{2}*(-2)+b\\\\3=1+b\\ 3-1=1+b-1\\2=b\\Thus,\\y=-\frac{1}{2} x+2[/tex]
The required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).
Given that,
To determine points using a slope of -1/2 and the point (-2,3).
Coordinate, is represented as the points on the x-axis and y-axis of the graph.
Here,
using the slope-intercept form of the equation,
y = mx + c
we have a point (-2, 3) and m = -1/2
Put point and slope in the equation,
3 = -1/2 * -2 + c
c = 3 - 1
c = 2
Now equation would be
y = -1/2x + 2
Now,
For x = 0
y = 2
Coordinate will be (0,2)
For x = 1
y = -1/2 + 2
y = 3/2
Coordinate will be (1, 3/2)
For x = 2
y = -1/2 * 2 + 2
y = 1
Coordinate will be (2, 1)
Thus, the required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).

CJ wants a new video game but is not sure which one to buy. His choices are 5 sports games, 3 role-playing games, and 8 action games. He writes the game titles on pieces of paper and puts them all in a bag. He wants to buy two different games. If he randomly selects two names from the bag, what is the probability that CJ selects two sports games?
Answers
Answer:
1 /12
Step-by-step explanation:
Given that:
Number of sports game = 5
Role playing games = 3
Action games = 8
Total = (5 + 3 + 8) = 16
The probability of selecting two sports game from the bag :
First selection = sport game and second selection will also be a sport game.
This scenario with be a selection without replacement pattern
First selection :
Number of sports game / total number of options
5 / 16
SEcond selection : total left = 16 - 1 = 15 ; number of sports game = 5 - 1 = 4
Hence
P(sports on second selection) = 4 / 15
P(sports on first and second) :
5/ 16 * 4/15 = 20/ 240 = 1 / 12
