Answer:

Required ration which represent the situation = \frac{-13}{2}

Step-by-step explanation:

Given: Cars in parking lot decreases at rate of 13 cars every 2 minutes.

To find: Rational Number which represent given information

Rational Number is a number in form of  \frac{p}{q} where p be any integer and q is non zero integer.

So from given information

No of cars decreases in 2 minutes = 13 cars

So, No of cars decreases in 1 minute = \frac{13}{2}

Therefore rate at which cars decreasing in parking lot is  \frac{13}{2}  cars/min.

Since it is decreasing, ration which represent it must be equal to \frac{-13}{2}

Therefore, Required ration which represent the situation = \frac{-13}{2}

The diagram shows a right angle.<br> Write an equation to determine the value of x. Solve for x.
kramer

Answer:

8x + (6x + 6) = 90°

x = 6°

Step-by-step explanation:

because it is a right angle, the sum of the angles = 90°

8x + (6x + 6°) = 90°

simplify:

14x + 6° = 90°

subtract 6° from each side:

14x = 84°

divide both sides by 14:

x = 6°
