A triangular window has an area 240 square feet and height 16 feet. What is its base?

30 ft

Step-by-step explanation:

Formula to find the area of a triangle is :

Area = × base × height

Given that,

Area of the triangle = 240 ft²

Height = 16 ft

Base = ??

Let us find now.

Area = × base × height

240  =  = × b × 16

240 × 2 = 16b

480 = 16b

Divide both sides by 16.

30 ft ⇒ base

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'.
