Mindy earns income equal to 40% of her sales minus the shipping cost of her products. She wants her income to be at least $1,500 this month and calculates that her total shipping cost will be $48. This can be represented by the inequality 0.4x−48≥1,500, where x represents the amount of her sales in dollars. What is the LEAST amount of sales Mindy must have to ensure that her income is at least $1,500 this month?

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'.
