If x varies inversely as t, and x = 8 when t = 6, find t when x = 12- =

Mathematics

Answer:

t = 4

Step-by-step explanation:

given x varies inversely as t , then the equation relating them is

x = \frac{k}{t}  ← k is the constant of variation

To find k use the condition x = 8 when t = 6 , then

8 = \frac{k}{6} ( multiply both sides by 6 )

48 = k

x = \frac{48}{t} ← equation of variation

when x = 12 , then

12 = \frac{48}{t} ( multiply both sides by t )

12t = 48 ( divide both sides by 12 )

t = 4

<h3>Answer:  B) 7 units</h3>

===========================================================

Explanation:

The y coordinates of the two points are the same, so we can subtract the x coordinates and apply absolute value

|R - T| = |-6 - 1| = |-7| = 7

Or we can say

|T - R| = |1 - (-6)| = |1 + 6| = |7| = 7

Either way, the two points are 7 units apart.

You could use the distance formula to get the same answer, but that's definitely overkill in my opinion. The trick mentioned above also could work if the x coordinates were the same, but the y coordinates were different. In any other case, you would have to use the distance formula.

The clock was exactly on time at 7am at 1pm the clock was 228 seconds late at that rate how slow was the clock half an hour
yan [13]

Answer:

19 seconds.

Step-by-step explanation:

Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:

1 PM = 13:00

13 - 7 = 6

228/6 = 38

38/2 = 19

Thus, every half hour the clock is delayed 19 seconds.

a map has a scale of 6 in : 36 mi. If Clayton and Clinton are 52 mi apart, then they are how far apart on the map?
cricket20 [7]
The map scale is 6 in : 36 mi

simplify it, divide 6 from both sides

6/6 = 1
36/6 = 6

1 in : 6 mi

To find the amount of inches in 52 miles, divide 52 with 6

52/6 = 8.67 (rounded)

8.67 in should be your answer

hope this helps
