Mike is driving a Toyota Camry. He’s inflated his tire to the dealer-recommend level of 32 PSI. At what speed will Mike’s car start hydroplaning? With what tire pressure would his car start hydroplaning at 45 miles per hour? Use the formula v=10.35 square root p

Answers

Answer 1

Answer:

Part A

A speed of approximately 58.55 mph

Part B

A pressure of approximately 18.9 psi

Step-by-step explanation:

Part A

The parameter for the car are;

The tire pressure, p = 32 psi

The given equation determined for the speed, 'v', when a car will start hydroplaning is presented as follows;

v = 10.35·√p

Where;

v = The speed at which the car is moving when it will hydroplane in mpj

p = The pressure in the tire in psi

The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi is therefore;

v = 10.35 × √(32 psi) ≈ 58.55 mph

The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi, v ≈ 58.55 mph

Part B

When a car is moving at, v = 45 mph, we have;

v = 10.35·√p

∴ The pressure in the car tire, p = (v/10.35)²

∴ at p = 45 mph, we have;

p = (45 mph/10.35)² ≈ 18.9 psi

The tire pressure at which Mike's car start hydroplaning, p ≈ 18.9 psi

six times the number plus
11. What is the number?

Answers

Answer:

-16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer : -16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer:

y = 27/6

Step-by-step explanation:

3/2x - 6 = -9/2x + 21

12/2x = 27

6x = 27

Since both are y, you know the values are equal to each other.
3/2x - 6 = -9/2x + 21
3/2x = -9/2x + 27
Get rid of fraction (multiply by 2)
3x = -9x + 54
12x = 54, x = 4.5
Plug 4.5 into any equation as x
y = 3/2(4.5) - 6
y = 6.75 - 6 = 0.75

Solution: y = 0.75 or 3/4
