The correct question is

A watch loses 30 secs every hour .If the watch was set right on Sunday 11:30pm .What is time did it show after 10 hours?

(a) Monday 9:25am

(b) Monday 9:30 am

(d) Monday 9:25pm

(a) Monday 9:25am

The time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

Step-by-step explanation:

We are given that a watch looses 30 seconds in one hour and the Watch was set on 11:30pm on Sunday.

we need to find the time this watch will show after 10 hours from starting at 11:30pm on Sunday.

In 1 hour = 30 seconds is lost

In 10 hours = 30*10 = 300seconds

Converting 300 seconds into minutes we get

= 300/60 = 5 minutes

This means whatever the actual time will be this watch will shows 5 minutes less.

10 Hours from 11:30pm on Sunday will be

9:30am on Monday morning

but since the watch is slow by 30 seconds each hours which will make 5 minutes difference from the real time in 10 hours so the time shown by the watch will be

9:25am on Monday morning.

Therefore the time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

just pick what you think i need more time let me know if this

step-by-step explanation:

Answer from: Quest

answer:

given the linear inequality : $x-2y\geq -12$

add 2y to both sides we get;

$x-2y+2y\geq -12+2y$

simplify:

$x\geq -12+2y$

add 12 to both sides of an equation;

$x+12\geq -12+2y+12$

simplify:

$x+12\geq 2y$

divide both sides by 2 we get;

$\frac{x}{2} + 6 \geq y$

$y\leq \frac{x}{2} + 6$

the related equation for the inequality equation [1] is;

$y =\frac{x}{2} +6$

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

$y =\frac{0}{2} +6$

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

$0 =\frac{x}{2} +6$

subtract 6 from both sides we get

$0-6 =\frac{x}{2} +6-6$

$-6 =\frac{x}{2}$

multiply both sides by 2 we get;

$-6 \times 2=x$

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
