In a fish tank, 1/2 of the fish have a red stripe on them. if 10 of the fish have red stripes, how many total fish are in the tank?

20

Step-by-step explanation:

20 fish are in the tank

Step-by-step explanation:

If 1/2 of the fish have stripes and there are 10 fish with stripes then you would take the reciprocal of 1/2 which is 2/1 or 2 and multiply it by 10

10*2/1=20

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'.
