Answer:

12 hits

Step-by-step explanation:

Let x be the number of hits needed

1 hit equals an at-bat.

(45+x)hits / (130+x)at-bats = 0.4

(45+x) = 0.4(130+x)

45 + x = 52 + 0.4x

45 - 52 = 0.4x - x

-7 = -0.6x

x = -7/-0.6

x = 11.667

x = 12(approximately)

12 hits are necessary since there are no fraction of hits

Give an example of tangents in the real world that have not been presented in this lesson.
german

Answer:

Hey! Sorry im too late lol but here-

Step-by-step explanation:

Example of tangent in the real world-

When a stone gets tied at one end of a string & the other end is rotated, then the stone will form a circle.

How you know the tangent and radius are perpendicular:

The radius is formed vertically and is completely straight, while the tangent is completely straight but horizontal. You can draw a right triangle angle between the radius and tangent line by adding a third line, and a right angle is 90 degrees. So, this forms a perpendicular line.

Hope this helped :))
