A kite has A=120 cm2 and d1=16 cm. Identify the length of d2. A) d2 = 15 cm
B) d2 = 7.5 cm
C) d2 = 12 cm
D) d2 = 18 cm

d2 = 15 cm

Step-by-step explanation:

The area of a kite with diagonald d1 and d2 is

A = 1/2(d1)(d2)

From the formula A = 1/2(d1)(d2) find d2.

d2 = 2A/d1

Substitute A = 120cm2 and d1 = 16 cm.

d2 = 2(120)/16

simplify.

d2 = 15 cm

Therefore, the length of d2 is 15 cm.

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'.
