Mark wants to buy shoes that cost 200 dollars. they have him a dicount for 20 dollars and he used his 2 percent coupen. how much did mark pay for the shoes

$176.40

Step-by-step explanation:

Lets assume the order of events to be:

20 dollars discount first,

2% coupon discount, next

So, original cost is 200

Discount of 20 dollars, means that it now costs:

200 - 20 = $180

Now, we have a 2% discount coupon on it. We have to find 2% of 180 and subtract that from 180.

Note: 2% is 2/100 = 0.02

So,

180 * 0.02 = 3.6

So, final price would be:  180 - 3.6 = $176.40

Mark paid $176.40 for the shoes

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'.
