Tony is reading a book that is 707 pages long. If he is 76% done, how many pages has he read?

apporoximately 537.

Step-by-step explanation:

you take 76% of 707. in this case you end up with a decimal but you should round to the nearest tenth

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'.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
