sin(b) = 0.8

Step-by-step explanation:

The sine is equal to the length of the side opposite the angle, divided by the length of the hypotenuse.

In this case, the side in question has a given length of 8, and the hypotenuse 10, so the sine of B is equal to 8 / 10, or 0.8

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'.
