Round to the nearest tenth 200 meters,19.30 seconds, usain bolt, jamaica

Rounding numbers make numbers easier to work with. The tenths is the place found immediately to the right of the decimal point. The next place is called the hundredths. If the number in the hundredths place is 5 or above, we add one to the number in the tenths place and let the other numbers go. If the number in the hundredths place is four or below, we let the other numbers go.

First. 200

200 is already rounded to the nearest tenth. Note that there is no any decimal point.

Second. 19.30 seconds

The number in the tenth place is 3 and the number in the hundredth place is 0, that is, zero is less than four, therefore we can say that this number rounded to the nearest tenth is:

19.30 or 19.3

Third. Usain bolt, jamaica

We can't round words. This concept is apply only to real numbers.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
