There were 90 runners to start a race. in the first half of the race, 1/3 of them dropped out. in the second half of the race, 3/5 the remaining runners dropped out. how many runners finished the race?

24

Step-by-step explanation:

Start with 90 runners.

1/3 dropped out.

1/3 of 90 = 1/3 * 90 = 30

30 runners dropped out.

90 - 30 = 60

Now there are 60 runners.

3/5 of the remaining runners dropped out.

3/5 of 60 = 3/5 * 60 = 36

36 runners dropped out.

60 - 36 = 24

24 runners finished the race.

24 runners

Step-by-step explanation:

1/3 of 90 dropped =  30 dropped

90-30=60

Second half  60 runners

3/5 of 60 dropped  = 36 dropped

36 runners dropped in second half

60-36=24

24 runners finished  the race

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
