If the two spinners below are spun once each, what is the probability that you will spin a total of 8?

3 / 16

Step-by-step explanation:

8 and something else won't be it, they already have 8. This rules out 4 of 16

Then for the rest of the numbers,

1 + 7 = 8

2+6 = 8

And

3+5 = 8

This is 3 options out of 16

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'.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
