Step one:
given data
We have a question to answer
given that the speed is 6 mph and the time taken is 3 hours
v= 6mph, t= 3, distance =?
distance= speed * time
distance= 6*3= 18miles
From the distance calculated, we can see that there exist a proportional relationship, lets say the time taken is 4 hours, then the distance will be
distance= 6*4= 24 miles.
hence the distance traveled is proportional to the time taken
While shopping at the mall, Jonathan saw two toys he wanted to buy. The toys originally cost $15.95 and $11.65,
but they were on sale for off the regular price.
Jonathan paid for the toys with a $20 bill. Which expression can be used to determine how much change Jonathan received?
20-1/3(15.95+11.65)
20-((15.95+11.65)-1/3(15.95+11.65))
((15.95+11.65)-1/3(15.95+11.65))-20

A car tracked 600 miles in 5 hours. what is the average speed of the car ?
Answer:
120 mph
Step-by-step explanation:
How to calculate is 600/5
Answer
The average speed of the car is 120 miles per hour.
Explanation
The formula to find speed is distance over time.
600 miles is the distance.
5 hours is the time.
So divide 600 by 5.
600 divided by 5 is 120, meaning the average speed of the car is 120 miles per hour.

The leg of a right triangle is 3 units and the hypotenuse is 6 units. What is the length, in units, of the other leg of the triangle? (5 points)
Answer:
a. rad27
Step-by-step explanation:
we can use a2+b2=c2 where c is the hypotonuse.
we plug in 3^2+b2=6^2
9+b^2=36
b^2=27
then do a rad over each to get rid of the ^2 on the b
b=rad 27
answer is rad27
8 divided by 832 (long division)
Answer:
Step-by-step explanation:
832/8 math problems division = 104. Therefore 104 to 2 decimal places= 104
832/8 divided by 2 » (832/8) ÷ 2 » 104 ÷ 2 = 52
Angle a is 5/3 of Angle b.
Find Angles a and b plz
Answer:
Angle a = 112.5°
Angle b = 67.5°
Step-by-step explanation:
Angle a + angle b = 180° (Supplementary Angles/angles on a straight line)
Let x = m<b
m<a = ⁵/3(x)
Therefore:
⁵/3x + x = 180
[tex] \frac{5x}{3} + x = 180 [/tex]
[tex] \frac{5x + 3x}{3} = 180 [/tex]
[tex] \frac{8x}{3} = 180 [/tex]
Multiply both sides by 3
[tex] \frac{8x}{3} \times 3 = 180 \times 3 [/tex]
[tex] 8x = 540 [/tex]
Divide both sides by 8
x = 67.5°
Angle a = ⁵/3(x) = ⁵/3(67.5) = 112.5°
Angle b = x = 67.5°

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,
Number of practice weeks = 5
Number of practice days in a week = 5
The total number of practice days.
= 5 x 5
= 25 days
Total time for 25 practice days = 37.5 hours.
The number of hours each practice day.
= 37.5 ÷ 25
= 1.5 hours
Thus,
1.5 hours of practice each day.

Inverse function details
Step-by-step explanation:
First, replace f(x) with y ⇒ f(x)=6x-19 ⇒ y=6x-19
Then y with x and x with y ⇒ y=6x-19 ⇒ x=6y-19
Solve the equation from for y:
x=6y-19
x+19=6y dividing with 6
1/6 x +(19/6) = y
Replace y with f−1(x) ⇒ f−1(x)= 1/6 x +(19/6)

answer question 4 pleaseeeee
Answer:
a) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8
b) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32
Step-by-step explanation:
We are given function [tex]f(x)=4(2)^x[/tex]
We need to find Average rate of change
The formula used is: [tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}[/tex]
Part a) The interval is: x=1 to x=2
We have a= 1 and b=2
Finding f(a) i.e f(1)
[tex]f(x)=4(2)^x\\Put \ x =1\\f(1)=4(2)^1\\f(1)=4(2)\\f(1)=8[/tex]
Now finding f(b) i.e f(2)
[tex]f(x)=4(2)^x\\Put \ x =2\\f(2)=4(2)^2\\f(2)=4(4)\\f(2)=16[/tex]
Now finding average rate of change.
[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{16-8}{2-1} \\Average \ rate \ of \ change=\frac{8}{1}\\Average \ rate \ of \ change=8[/tex]
So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8
Part b)
The interval is: x=3 to x=4
We have a= 3 and b=24
Finding f(a) i.e f(3)
[tex]f(x)=4(2)^x\\Put \ x =3\\f(3)=4(2)^3\\f(3)=4(8)\\f(3)=32[/tex]
Now finding f(b) i.e f(4)
[tex]f(x)=4(2)^x\\Put \ x =4\\f(4)=4(2)^4\\f(4)=4(16)\\f(4)=64[/tex]
Now finding average rate of change.
[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{64-32}{4-3} \\Average \ rate \ of \ change=\frac{32}{1}\\Average \ rate \ of \ change=32[/tex]
So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32
Since the interval is increasing, so does our average rate of change increasing as function is also increasing.
