Answers
Answer with explanation:
Part A:
- A relation is said to be a function where each input has only a single output.
We usually take the input variable as 'x' and the output variable as 'y'.
In the given table, we can see that 1 is the input value corresponding to 4 and 2 both.
i.e. one input value corresponds to two different output values that contradicts the definition of the function.
Thus the given table doesn't represent any function.
Part B: Given : The total cost f(x), in dollars, for renting a paddle-boat for x hours is shown below:
At x= 120 ,
It represents that the total cost for renting a paddle-boat for 120 hours is $1220.
The table doesn't represent y as a function of x.
Why? One reason is that 1 or 3 is the first element in more than one ordered pair.
Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220
f(120) represents cost of boating for 120 hours.

=> A piece of plywood is 24 inches wide
=> it will be cut into strips of 2 ½ inches wide.
Now, we need to find the numbers of strips in 24 inches plywood.
To do that, we simply need to divide 24 inches from 2 ½ inches.
=> Since 2 ½ is a mixed fraction (combination of whole number and fraction), we need to convert it into improper fraction.
=> 2 ½ = 5/2
=> 24 = 24/1
Now, we have 2 fractions. Let’s divide
=> 24 / 5
1 2
=>24 / 5 = 48 / 5
1 2 2 2
=> 9.6 or 9 3/5
Thus, there will be 9.6 or 9 3/5 of plywood strips.
Answer:
9 inches
Step-by-step explanation:
24/2.5 is 9.6 BUT 0.6 IS NOT A FULL PIECE, SO IT IS 9 INCHES

Answer:
Stan: y=6x+50
Kyle: y=10x+34
Step-by-step explanation:
The y-axis starts at 50 and increases by 6 for Stan's
The y-axis starts at 34 and increases by 10 for Kyle's
hope this helps
Kyle: 10w + 34
The 50 and 34 are added in the equations because this is the amount that Stan and Kyle started out with. The w in the equations represents the number of weeks that Stan and Kyle save their different amounts of money.

Solve:
6 = -w/8
Multiply by 8 on both sides to get the variable alone.
48 = -w
We found the answer for negative w, but we want the answer for w.
48/-1 = -48
-48 = w
First, multiply both sides by 8. / Your problem should look like:
Second, multiply both sides by -1. / Your problem should look like:
Third, switch sides around. / Your problem should look like:
Answer: w = -48

It takes 30 minutes.
It rotates (360/30) = 12 degrees every minute.
In 12 minutes, 1 seat will rotate (12 x 12) = 144 degrees.
============================================
A slightly different way to do it:
1 rotation = 360 degrees
It takes 30 minutes.
12 minutes = (12/30) = 0.4 of a complete rotation.
0.4 of 360 degrees = (0.4 x 360) = 144 degrees
============================================
A slightly different way to do it:
Set up the proportion:
(30 minutes / 360 degrees) = (12 minutes / 'x' degrees)
Cross-multiply the proportion:
30 x degrees-minutes = (12 x 360) degree-minutes
Divide each side by '30 minutes':
'x' degrees = (12 x 360 degree minutes) / 30 minutes = 144 degrees
12minutes times 12 degrees equals 144 degrees.
