the water level of a lake fell by 1 1/4 in during a 1 1/2 week long dry spell simplify the complex fraction below to find the average rate at which the water level changed every week

Step-by-step explanation:

Rate of drop = level drop / time:

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'.
