We can determine the value of the adult ticket cost and student ticket cost by following these steps:

1. solve form one of the variables from one of the equations

Let's solve for a from 2a + 2s = 40

2a + 2s = 40

2a + 2s - 2s = 40 - 2s

2a = 40 - 2s

2a/2 = 40/2 - 2s/2

a = 20 - s

2. Replace the expression found and solve for s

4a + 5s = 87

4(20 - s) + 5s = 87

4×20 - 4×s + 5s = 87

80 - 4s + 5s = 87

80 + s = 87

80 - 80 + s = 87 - 80

s = 7

3. Replace 7 for s into a = 20 - s

a = 20 - 7

a = 13

Then, a = 13 and s = 7.

Then the adult ticket cost is $13 and the student ticket cost is $7

Softa [21]

Answer:

a)- Given that a student is a 10th grader, there is a 14% chance he or she has a job.

Step-by-step explanation:

Option (a) is correct here because Relative frequency means the probability of occurrence or number of time-specific event occurs to the total event.

Option (b) is not correct because We already know that student is in 10th or 11th grade, after that we get to know about 14% chance.

Option (c) & (d) are clearly not possible.

Find parametric equations for the sphere centered at the origin and with radius 3. Use the parameters s and t in your answer. x(
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

In general (x, y, z) = (p ·cos s ·sin t, p· sin s· sin t, p · cos t) where p is radius

x(s, t)= 3 ·cos s ·sin t

y(s, t)= 3· sin s· sin t

z(s, t) = 3· cos t

Where, radius is 3, s ∈ [0,2π), and t ∈ [0, π]

Marat540 [252]

Answer:

The area of the shaded region is 42.50 cm².

Step-by-step explanation:

Consider the figure below.

The radius of the circle is, <em>r</em> = 5 cm.

The sides of the rectangle are:

<em>l</em> = 11 cm

<em>b</em> = 11 cm.

Compute the area of the shaded region as follows:

Area of the shaded region = Area of rectangle - Area of circle

                                            =[l\times b]-[\pi r^{2}]\\\\=[11\times 11]-[3.14\times 5\times 5]\\\\=121-78.50\\\\=42.50

Thus, the area of the shaded region is 42.50 cm².
