Hurry in need for the product of 5 and a number x is 1/4 . what is the value of x.

We are given 5 and x need to multiply ( the product represents multiplication operation).

"The product of 5 and a number x is 1/4" statement can be expressed as in equation form.

5 * x = 1/4 .

On multiplying 5 and x, we get 5x.

Therefore, 5 * x = 1/4 can be written as

5x =1/4.

We are solving it for unknow number x.

So, we need to isolate it for x on left side.

We need to get rid 5 from left side in order to isolate it for x.

Dividing both sides by 5, we get

x=

Therefore, required number is 1/20.

So, second option 1/20 is correct option.

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'.
