The area, A square feet, of the wall Ivan is painting is directly proportional to the time he spends painting the wall, T hours. It takes Ivan 4 hours to paint 113.6 feet of the wall. How long will he take to paint 227.2 square feet of the wall?

4 hours

Step-by-step explanation: Square feet of the wall F²∆ T

F² = KT

113.6² = K4

K= 12,904.96

Time to paint 227.2 is;

F² = KT

227.2² = 12,904.96x T

T = 51,619.84/12,904.96

T= 4 hours

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

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'.
