Find y.
PLEASE HELP ASAP

y = 4

Step-by-step explanation:

y = 4

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = , then

cos45° = = = ( cross- multiply )

y × = 4 ( divide both sides by )

y = 4

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

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'.
