Peter is typing an essay for his science class. The essay needs to be 3,200 words long. Peter can type 15 words per minute. If Peter has 500 words typed so far, how many hours will it take for Peter to finish typing the essay? (it says the answer needs to be a whole number)

3 hours

Step-by-step explanation:

3200 - 500= 2700 <words he need to type

2700 : 15= 180<minutes

180= 3 hours

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".

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'.
