Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
Arada [10]

Answer: 200 adult tickets and 400 student tickets were sold.

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of student tickets that were sold.

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $850, the expression would be

1.75x + 1.25y = 850- - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This is expressed as

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 850

1.75x + 2.5x = 850

4.25x = 850

x = 850/4.25

x = 200

y = 2x = 2 × 200

y = 400

A balloon attached to an atmospheric data-gathering device must be at least 1000 m high to begin recording information. Two spot
maks197457 [2]

The angle of elevation that the instruments have to record to be at the correct height is given as 79°

<h3>How to solve for the angle of elevation</h3>

We have 2x + 70 = 180

We have to find the value of x

2x = 110

x = 55

y/sin x = 225/sin70

This is the use of sine rule

From here we would have

y = 225(sinx/sin70)

Remember x = 55

y =  225(sin55/sin70)

y = 196.1378

tanθ = 1000/y

tan θ = 1000/196.1378

tanθ = 5.098

θ = tan⁻¹5.098

= 78.90°

Hence the conclusion is that the angle of elevation has to be 78.9 degrees for it to be at the correct height.

Find the exponential function that satisfies the given conditions:
swat32

<u>Answer-</u>

<em>The exponential function that satisfies the given conditions is f(t)=67(0.9953)^t</em>

<u>Solution-</u>

This can be represented as exponential decreasing function,

f(t)=a(1 - r)^t

Where,

  • a = starting amount = 67
  • r = rate = 0.47% = 0.0047
  • t = week

Putting the values,

\Rightarrow f(t)=67(1 - 0.0047)^t

\Rightarrow f(t)=67(0.9953)^t

Therefore, the exponential function that satisfies the given conditions is

f(t)=67(0.9953)^t
