16. An object travels along a horizontal straight path at a constant rate. The object travels zo of the length of the path in second. At that rate, how many seconds does it take the object to travel the entire length of the path?

Step-by-step explanation:

Step-by-step explanation:

1/20 is a tiny portion of the length that needs to be traveled.  20/20 is the whole length.  If 1/20 gets traveled in 3/4 of a second, multiply 3/4 by 20 to see how long it takes to travel 20(1/20) which is equal to 1, the whole path.

20(3/4) = 15 seconds

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'.
