1. 1:38 AM to 4:38 AM is 3 hours, 4:38 AM to 4:50 AM is 12 mins. This means that total time elapsed is 3 hours and 12 mins. Rounding to nearest hour gives 3 hours.

2. I assume you mean 11:49 AM. 11:49 AM to 6:49 PM is 7 hours. 6:49 PM to 7:12 PM is 23 mins. Total time is 7 hours 23 mins, or 7 hours to the nearest hour.

3. 2:25 PM to 3:25 PM is 1 hour, 3:25 PM to 3:35 PM is 10 mins. Total time is 1 hour 10 mins or 1 hour to the nearest hour.

4. 8:25 AM to 10:25 AM is 2 hours. 10:25 AM to 10:52 AM is 27 mins. Total time is 2 hours 27 mins or 2 hours to the nearest hour.

The trick is to count the number of hours first, then count the number of minutes remaining.

Triss [41]

Answer:

(-10, 0) and (0,-5)

Step-by-step explanation:

For the function f(x)=-\dfrac{1}{2}x-5, find x-intercept and y-intercept:

1. when y=0, then

0=-\dfrac{1}{2}x-5,\\ \\\dfrac{1}{2}x=-5,\\ \\x=-10;

2. when x=0, then

y=-\dfrac{1}{2}\cdot 0-5,\\ \\y=-5.

You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function f(x)=-\dfrac{1}{2}x-5.

PLEASE HELP I REALLY NEED IT
Aleonysh [2.5K]

Answer:

9. Force is required to change an object velocity.Force is equal to mass times acceleration.

10.  Force acting on object are paired with equal and opposite forces

Step-by-step explanation:

9.

Newton's 2nd law states that force is a product of mass and acceleration.In this case, the force of friction is causing deceleration of the ball.This is an example of rolling friction.Acceleration of the ball depends directly on this friction but indirectly on its mass.

10.

From Newton's 3rd Law ,for every action there is an equal and opposite reaction.The astronaut throwing the ball will experience the effect of an external force againts his own which is equal  and  in the opposite direction to the force she applied.This is why the astronaut moves backward but slower.

Y = 2x + 3
BARSIC [14]

Answer:

Infinite solution

Step-by-step explanation:

There is 3 possible solutions to a system of linear equations:

  • One solution - two distinct lines that do not share y-intercept or slop intersect at a point
  • No solution - two distinct lines that share the same slope but not the same y-intercept never intersect and are parallel
  • Infinite solution - one distinct function represented two ways which in simplest form share the same slope and y-intercept

The first equation is in simplest form y=2x+3.

The second equation 2y=4x+6 when simplified becomes y=2x+3.

These are the same lines with the same slope and y-intercept. Therefore, they have infinite solutions.
