Troyanec [42]

Answer:

The person's height must be greater than or equal to 55 inches to go on the ride

Step-by-step explanation:

Let

x -----> the height of the person

we know that

A person must be at least 55 inches tall to go on the carnival ride

The phrase " at least" means "greater than or equal to"

so

The inequality that represent this situation is

$x\geq 55\ in$

therefore

The person's height must be greater than or equal to 55 inches to go on the ride

Please help.. what is the function rule for the perimeter P of a building with a rectangular base if the width w is two times th

Otrada [13]

<span>For the answer to the question above, this is the formula for finding the rectangular base.
P = 2L + 2W</span>Consider the Width being twice as long as the length. If we write it down, it will look like this<span>W= 2 L</span>We'll plug that into the perimeter equation,<span>P = 2L + 2W→ P = 2L + 2(2L)</span>Now, just simplify the equation and problem is solved.
I hope I helped you with my answer.

A Lamborghini veneno and a ford pinto leave cities 1040 miles apart, speeding towards each other, The veneno’s speed is 180 mile

Kisachek [45]

Answer: The speed of the veneno is 220 miles per hour.

Step-by-step explanation:

We have the relation:

distance = speed*time.

We can model this situation as:

The cars will pass eachother when the sum of their distances traveled in the given time, 4 hours, is equal to the initial separation between them, 1040 miles.

So we have:

Sv = speed of the veneno.

Sp = speed of the pinto.

Sv*4hours + Sp*4hours = 1040 miles.

Now, we know that:

Sv = Sp + 180mph.

We want to find the speed of the veneno, so we should write:

Sp = Sv - 180mph.

Then we can replace this in our equation as:

Sv*4h + Sp*4h = 1040mi

(Sv + Sp)4h = 1040mi

(Sv + (Sv - 180mph))*4h = 1040 mi

(2*Sv - 180mph)*4h = 1040mi

2*Sv*4h - 720mi = 1040mi

Sv*8h = 1040mi - 720mi = 1760mi

Sv = 1760mi/8h = 220 mi/h

The speed of the veneno is 220 miles per hour.

A race pilot's average rate of speed over a 720-mile course is inversely proportional to the time in minutes t the pilot takes t

alexira [117]

If d = rt, Then r = d/t
avg speed = 720/t

Therefore after subtracting penalty points, the function for score is:
$s = \frac{720}{t} - p$

For part 2 i will attach a picture.

Part 3)
Set s = 3 and solve for t
$\frac{720}{t} - 2 = 3$
$720 = 5t$
$t =144$
