Answers

Answer:

i. 31/25

ii. 1/5

Step-by-step explanation:

you know that tanx = 3/4, so you can also find that sinx = 3/5 and cosx = 4/5. Then you can use the double angle identities to find cos2x and sin2x: cos^2(x) - sin^2(x) + 2sinxcosx and substitute the givens to get 31/25. Then, cosx - sinx is obviously 1/5.

There are 80
students in a speech contest. Yesterday,

1

4
of them gave their speeches. Today,

2

5
of the remaining students gave their speeches. How many students still haven't given their speeches?

Answers

yesterday, 1/4 of 80 =20 gave their speeches, so there are 80-20=60 students left.
Today, 2/5 of 60=24 students gave their speeches, so there are 60-24=36 students who still haven't give their speeches
another way to think of it is 80*(1- 1/4)*(1- 2/5)=80*(3/4)*(3/5)=36

Final answer:

To find the number of students who haven't given their speeches, subtract the number of students who have given their speeches from the total number of students. Yesterday, 14 students gave their speeches and today, 25 more students gave their speeches. So, there are 41 students who still haven't given their speeches.

Explanation:

To find the number of students who haven't given their speeches, we need to subtract the number of students who have given their speeches from the total number of students.

Yesterday, 14 students gave their speeches, so there are 80 - 14 = 66 students remaining.

Today, 25 students gave their speeches, so there are 66 - 25 = 41 students who still haven't given their speeches.
