Olivia is going to an amusement park. The price of admission into the park is $40, and once she is inside the park, she will have to pay $4 for every ride she rides on. How much money would Olivia have to pay in total if she goes on 13 rides? How much would she have to pay if she goes on r rides?
Cost for 13 rides:
Cost for r rides:
Answer:
Cost for 13 rides: $92
Cost for r rides: I am guessing it would be 40+4r
Step-by-step explanation:
If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
2.Ellington earns $210 for working 10 hours. How much does he earn per 40 hours?
Answer: $840
Step-by-step explanation:
Set up the proportion 210/10 = x/40.To solve it quickly, multiply 210 with 4, since 10*4 = 40. Therefore, x = 840.How to convert 3100.0 × 10² into scientific notation
Answer: 3.1 x 10 ^5
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The required scientific notation of the number 3100 * 10² is [tex]3.1*10^5[/tex].
Given that,
To convert 3100.0 × 10² into the scientific notation.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is scientific notation?Scientific notation is appropriate formate of large values like 100000 = [tex]10^5[/tex] is called scientific notation,
Here,
3100 * 10² = 3.1 * 1000 * 10²
3100 * 10² = 3.1* 10³ * 10²
3100 * 10² = 3.1 ([tex]10^{3+2}[/tex])
3100*10² = [tex]3.1*10^5[/tex]
Thus, the required scientific notation of the number 3100 * 10² is [tex]3.1*10^5[/tex].

Frank's Auto Corner recorded its sales for the second quarter (April, May and June) of 1999. April sales were 89 cars, May sales were 98 cars, and June sales were 115 cars. During the same quarter in the previous year, 1998, the total sales were 287 cars. How many cars were sold at Frank's Auto Corner during the second quarter of 1999? How many more cars were sold during the second quarter in 1999 than in the second quarter of 1998? Explain how you got your answer.
The number of cars sold at Frank's Auto Corner during the second quarter of 1999 is 302 cars.
The number of cars sold by which 1999 sales exceeds 1998 sales is 15 cars
What is the number of cars sold in second quarter of 1999?
The number of cards sold by Frank's Auto Corner in the second quarter of 1999 is the sum of April sales, May sales and June sales as provided in the scenario given, hence, we just need to sum up the three figures to ascertain total number of cars sold
cars sold in second quarter 1999=89+98+115
cars sold in second quarter 1999=302 cars
The difference between the number of cars sold in second quarter of 1999 over that sold in the second quarter of 1998 is computed by taking the difference between 302 cars and 287 cars
difference in car sales=302-287
difference in car sales=15 cars

Drag numbers to complete the table for missing values of x, x2, and x3.
Answer: The filled out table is shown in the attachment below
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216
=======================================================
Explanation:
In the first row we have x^2 = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.
So we'll have 2 in the first box of row 1.
If x = 2, then x^3 = 8 after cubing both sides.
In other words, x^3 = 2^3 = 2*2*2 = 8
The value 8 goes in the other box of row 1.
---------------
For row 2, we use x = 6 to square that to get x^2 = 6^2 = 6*6 = 36.
36 will go in the blank box for row 2

determine the x-intercept and y-intercept of the following linear equations
standard form and show you did it
Answer:
Step-by-step explanation:
the x intercept takes coordinate (x,0)
the y intercept takes coordinate (0,y)
x intercept y intercept
40: x+y=5 (5,0) (0,5)
x=0 , y=5, when y=0 x=5
41: x-y=5 (5,0) (0,-5)
x=0, -y=5 then y=-5, when y=0, x=5
42: 3x+4y=12 (4,0) (0,3)
x=0, 4y=12⇒y=12/4⇒y=3
y=0, 3x=12⇒x=12/3⇒x=4
43: 2x+3y=6 (3,0) (0,2)
x=0 , 3y=6⇒y=6/3=2
y=0 ,3y=6 ⇒ y=6/3 ⇒y=2
44: 3x+4y=-24 (-8,0) (0,-6)
x=0 , 4y=-24⇒y=-24/4 ⇒ y=-6
y=0 , 3x=-24⇒ x=-24/3⇒x=-8
45: 1/3x+2/3y=5/6 (5/2,0) (0,5/4)
x=0 , 2/3 y=5/6 ⇒12y=15 ⇒ y=15/12 ⇒y=5/4
y=0 , 1/3 x=5/6 ⇒6x=15 ⇒x=15/6 ⇒x=5/2
46: x=-2 (-2,0) no y intercept
it is vertical line , there is no y intercept
47: y=15 no x intercept (0,15)
horixzontal line, no x intercept
48: 3x-7y=8 (8/3,0) (0,-8/7)
x=0 , -7y=8 ⇒y=-8/7
y=0 , 3x=8 ⇒x=8/3
give the equation of the x- axis and identify the type of line it represents (vertical or horizontal ).
___Fill_in_blank_here_______________________________________
Answer:
Equation of x-axis is y=0, it is a horizontal line.
Step-by-step explanation:
We need to find the equation of the x- axis and type of line it represents (vertical or horizontal ).
On the x-axis, the value of y is always 0 and the value of x can be and real number. Since y is free from x and its value is 0, therefore the equation of x-axis is
[tex]y=0[/tex]
Value of y remains same. So, it represents a horizontal line which intersects the y-axis at 0.
Therefore, equation of x-axis is y=0, it is a horizontal line.

Diego's age d is 5 more than 2 times his sister's age s. This situation is represented
by the equation d = 2s +5. Which equation is equivalent to the equation d = 2s +5?
a. d = 2(s+5)
b. d - 5 = 2s
C.
d - 2 = s +5
d. = 5+5
Answer:
d-5=2s
Step-by-step explanation:
Diego's age d is 5 more than 2 times his sister's age s.
The equation used to represent it is :
d = 2s +5
We need to find the equivalent equation for the above equation.
If we take 5 to LHS of the equation, it will become -5 such that,
d-5=2s
Hence, option (b) is the equivalent equation.
