3 0
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.

Find the selling price of a $50 item after a 50 % markup
siniylev [52]

Answer:

75 dollars

Step-by-step explanation:

If an item is 50 and you want to markup 50%, you must find 50% of 50 to find how much the item will go up by from 50.

So 50% of 50 means 50% times 50.

50%=.5 or 1/2

So .5(50)=25.

The item is going up by 25 dollars.

So we started at 50 dollars.

So 50+25 is going to be the new amount.

50+25=75 is the new amount.

Which of the following line passes through point (-4,5) and is parallel to the line segment whose endpoints are at (-2,-3) and (
NNADVOKAT [17]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

Then, the requested line will have a slope equal to:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5 - (- 3)} {2 - (- 2)} = \frac {5 +3} {2 + 2} = \frac {8} {4} = 2

Thus, the line is of the form:

y = 2x + b

We substitute point (-4,5)and find "b":

5 = 2 (-4) + b\\5 = -8 + b\\5 + 8 = b\\b = 13

Finally, the equation is:

y = 2x + 13

Answer:

y = 2x + 13

Solve the inequality and graph its its solution -x/6 < 3​
ivanzaharov [21]

Answer:

Option C

Step-by-step explanation:

-x/6 ≤ 3

6(-x/6) ≤ 3 × 6

-x ≤ 18

-1(-x) ≤ -1(18)

x ≥ -18

So the line starts from -18 and extends infinitely to the right.
