a driver starts his parked car and within 5 seconds reaches a speed of 60 km / h, as he travel east. what is his acceleration?

1 answer:

5 0

Acceleration =

   (change in speed) / (time for the change)
AND
   (direction of the change)

-- Change in speed = (end value) - (start value) = 60 km/hr
      = 16-2/3 m/s
-- Time for the change = 5 sec

-- Direction of the change = east.

   Acceleration = 3-1/3 m/s² east .

Three times a number minus another number is -3. The sum of the numbers is 11. Find the numbers

MatroZZZ [7]

The first equation is

$3x-y=-3$

The second equation is

$x+y=11$

If you sum the two equations you'll cancel y:

$4x=8 \iff x=2$

And since the sum must be 11, we have y=9.

Varvara68 [4.7K]

Answer:

20.65 points.

Step-by-step explanation:

We have been given that a star athlete at a local college scored 640 points during the 31 basketball games. We are asked to find the average number of points she scored per game.

To find the average number of points scored per game by player we will divide total number scored by the total number of games.

$\text{Average number of points scored per game}=\frac{640}{31}$

$\text{Average number of points scored per game}=20.645161290322580\approx 20.65$

Therefore, the average number of points scored per game by the player is 20.65 points.
