These two prisms are similar. What is the value of y?

y is equal to 7

Step-by-step explanation:

the ratios on each side are 2 to 14, 9 to 63, and if you divide 14 by 2 you get 7. and if you divide 63 by 9 you get 7

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'.
