Answer:

Adults: 79 tickets

Students: 237 tickets

Step-by-step explanation:

a + b = 316    Eq. 1

b = 3a            Eq. 2

a = adults

b = students

Replacing Eq. 2 in Eq. 1

a + 3a= 316

4a = 316

a = 316/4

a = 79

from the Eq. 2

b = 3a

b = 3*79

b = 237

Check:

from the Eq. 1

a + b = 316

79 + 237 = 316

A circle has a circumference of 6. it has an arc of length 1/3
Maksim231197 [3]

Answer:

Ф = 10°

Step-by-step explanation:

Regarding arc length, s:  s = r·Ф, where Ф is the central angle in radians and r is the radius.

We need to find the central angle, Ф, in this problem.

We know that C = circumference = 6, and that this leads to r = 6/π.

Substituting 6/π for r and 1/3 for s in Ф = s / r, we get:

Ф in radians = 1/3  /  (6/π), or  Ф = π/18 rad.    

                                                                           π         180°

Converting this into degrees, we multiply    ------ by ----------

                                                                           18        π rad

obtaining:  Ф = 10°

7. When dy/dx = (x -6)1/2, what does y equal?
Sergio039 [100]
The answer is below
\frac{dy}{dx} = \frac{1}{2} (x - 6)
multiply both sides by dx

dy = \frac{1}{2} (x - 6)dx
integrate both sides of the diffrential

integral \: dy = integral \: \frac{1}{2} (x - 6)dx
simplify and integrate to get y alone don't forget to tack on c with your indefinite integral

y = \frac{x {}^{2} }{4} - 3x + c
