No problemo dude. So what do you know about sin θ·cot θ? Well, cot θ = cosθ/sinθ. Hence, the sin θ cancels out and what do you know? You are solving for cos θ. Now, you know that the quadrant is II (2). Hence, cos is also negative. So, tan θ = opp/adj = -(5/12). So, cos θ = adj/hyp which is just -12/13.

Three consecutive integers can be represented by the variable n, n+1 and n+2. If the sum of three consecutive integers is 57, wh

pashok25 [27]

You have some unknown integer $n$ , and you know that adding this and the next two integers, $n+1$ and $n+2$ , gives a total of 57.

This means

$n+(n+1)+(n+2)=57$

The task is to find all three unknown integers. Notice that if you know the value of $n$ , then you pretty much know the value of the other three integers.

To find $n$ , solve the equation above:

$n+(n+1)+(n+2)=3n+3=57\implies 3n=54\implies n=\dfrac{54}3=18$

So if 18 is the first integer, then others must be 19 and 20.

Four adults and five children go to see a movie and buy $15 worth of concessions. The total cost of their trip is $71. If each c

Answer:

$7.75

Step-by-step explanation:

Given: Adults = 4, Children = 5, All worth = $15, Total cost = $71, Each child's ticket = $5

To find: How much the adult tickets are

Solution: Use the 5 tickets at $5 to get $25

Add the $15 for concessions to reach $40

25 + 15 = 40

Subtract $40 from the 71 spent to get $31

71 - 40 = 31

Now, divide the 31 by 4 for the number of adults which equals $7.75

31 ÷ 4 = 7.75

So, the cost of the adults' tickets is $7.75
