Thirty miles per hour. First you divide 2,464 feet by 22.4. you should get 110 feet which is per second, then you multiply it by 60 representing one minute but in seconds, you should get 6,600 feet per minute, then you multiply it by 60 mins and you should get 396,000 feet per minute. Next, you multiply 396,000 by 24 hours, the result is 9,504,000 feet per hour. Finally, you divide 9,504,000 by 5280 (there is 5280 feet in one mile) and the answer is 30 miles per hour.

A right triangle has a base that measure 39 inches and a height that measures 80 inches. What is the length of its hypotenuse?

guajiro [1.7K]

The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)

What is the set fee, or initial value, of this function

Ber [7]

Answer:
The set fee would be $15

Explanation:
The set fee is the starting value. This means that it is the value of the y at x = 0 (y-intercept).

To get the set fee, we would first need to get the equation of the line.

Equation of the linear line has the following general formula:
y = mx + c
where m is the slope and c is the y-intercept

1- getting the slope:
we are given two points which are:
(20,25) and (50,40)
the slope = $\frac{y2-y1}{x2-x1}= \frac{40-25}{50-20} = 0.5$

The equation now is:
y = 0.5x + c

2- getting the value of the y-intercept:
To get the value of the c, we will use any of the given points, substitute in the equation and solve for c.
I will choose the point (20,25)
y = 0.5x + c
25 = 0.5(20) + c
25 = 10 + c
c = 15

The equation of the line representing the scenario is:
y = 0.5x + 15

Now, we know that the value of the c is the y-intercept which is the initial value of the function at x=0.
In our situation, this represents the set fee.

Hope this helps :)
