One of the highest snowfall rates ever recorded was in silver lake, colorado, in april 1922, when just over 7 feet of snow fell in one day. what was the rate in inches per hour? (1 foot = 12 inches, 1 day = 24 hours)

3 inches per hour

T calculate the rate change feet to inches and divide by 24

7 feet = 7 × 12 = 84 inches

rate = = 3.5 = 3 inches per hour

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
