Answer:
0
Step-by-step explanation:
=>sec A cosec A - tan A - cot A
=>(1/sinAcosA)-(sinA/cosA)-(cosA/sinA)
You get the LCM as sinAcosA then it becomes
=>(1-sin^2(A)-cos^2(A)) /sinAcosA [1-sin^2(A)=cos^2(A)]
=>(cos^2(A)-cos^2(A))/sinAcosA
=>0/sinAcosA
=>0
Answer: He could have played more than 3 games.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality.
I golf club charges $10 to join and $5 per game: So, the cost of playing golf is equal to $10 (joining price) plus the product of the number of games played (x) and the price per game (5).
That expression must be higher than 25, since john paid more than $25.
Mathematically speaking
10+ 5 x > 25
Solving for x
5x >25-10
5x >15
x >15/5
x> 3
He could have played more than 3 games, since his cost was higher ( not equal or higher) than 25.
The number if 18-year old 12-year old students that took part in the survey is 320.
- The number of more 18-year old students than 12-year old students that spent between 25 and 35 mins on social media is 20.
<h3>What is the survey about?</h3>
Looking at the survey chart one can see that the total number of 18year old that partook of the survey are:
30 + 20 + 60 + 70 + 40 + 60 + 40
= 340
From the diagram , 18 year old = 60
12 year old = 40
The differences will be:
= 60 - 40
= 20
Therefore, The number if 18-year old 12-year old students that took part in the survey is 320 and the number of more 18-year old students than 12-year old students that spent between 25 and 35 mins on social media is 20.
