Rita spent $90 at the grocery store. of this amount, she spent $81 on fruit. what percentage of the total did she spend on fruit

The percentage is the ratio of (amount spent on fruits/total amount)*100 = (36/45)*100 = (4*100)/5 = 80%

Rita spent a total of $90

She spent 81/90 dollars on fruit

To write 81/90 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .

81/90 * 100 = 0.9 * 100 = 90%

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'.
