Fifteen percent of the students in seventh grade at western middlr school have perfect attendance. there are 220 students in seventh grade. how many have perfect attendance

33 students

Step-by-step explanation:

Fifteen percent of the students in seventh grade at western middle school have perfect attendance. There are 220 students in seventh grade. How many have perfect attendance?

Fifteen percent in decimal from is 0.15.

You would then multiply that by the number of students; 220.

.15 * 220 =

One multiplied, you get 33.

Therefore, 33 students have perfect attendance.

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.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
