You need the formula: feet per second = feet/second
Now you have to recast the formula to:
feet per second * second = feet , because you want to know the number of feet.
At the bottom is the answer.
At last you have to insert the values:
28 feet per second * 20 seconds = 560 feet
Using proportions, the expected number of adults in Palm City whose main source of news is the internet or newspaper is of 19,413.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
From the table, the proportion of adults in Palm City whose main source of news is the internet or newspaper is found as follows:
p = (62 + 88)/(62 + 88 + 128 +24 + 38) = 0.4412.
Hence, out of 44,000 adults, the expected number is found as follows:
0.4412 x 44000 = 19,413.

Answer:
y + 1 = 3x
Step-by-step explanation:
The graphed line is y = 3x - 1
The options given to us are
y + 1 = 3x
y = -3x + 1
y = 3x + 1
y - 3x = -3
Consider the first equation:
y + 1 = 3x
Substitute (0,-1) into the equation:
-1 + 1 = 3(0)
0=0
Substitute (1,2) into the equation:
2+1 = 3(1)
3 = 3
Thus the equation holds true for the given points.
Rearrange the equation
y + 1 = 3x
y = 3x - 1
As it is the same equation which was initially graphed, both of these lines will be same and overlap each other, resulting in infinite number of solution
