Answer:

They bought 23 tickets for children and 52 for adults.

Step-by-step explanation:

So first you must find what i represents so here it is

A= Adult

C= Children

They both sold the tickets which is going to be

A + C = 75

Now here it shows

12= each adult ticket

8= each children ticket

find the equation like this 12 A + 8C = 808

Now to find the C

You can find by resolving it like this

C= 75 - A

Solve the A and C

4A = 208

A = 52

12 (52) + 8C = 808

624 + 8C = 808

Children = 23

Adult= 52

The angular velocity of a fan blade is 6.2 radians per second.
MA_775_DIABLO [31]

Answer:

94.7 revolutions

Step-by-step explanation:

In the question above, we are given the following values for the fan

Angular velocity = 6.2 radians per seconds

Time = 1.6 minutes.

Step 1

We would convert the time given to seconds

1 minute = 60 seconds

1.6 minutes = ?

We cross multiply

1.6 minutes × 60 seconds

= 96 seconds

Step 2

Number of revolutions made by the fan is calculated as :

Angular velocity(rad/s)

× time(seconds)

Number of revolutions = 6.2 radians per seconds × 96 seconds

=595.2 radians

Converting from radians to revolution

1 radian = 0.159155 revolutions

595.2 radians =

Cross multiply

= 595.2 radians × 0.159155 revolutions

= 94.729056 revolutions.

Approximately to the nearest tenth = 94.7 revolutions.

Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.

Please help ASAP 50 points :(((
Katyanochek1 [597]

Answer:

(f o g) (x) = 36x² + 3

(g o f) (x)  = 6x² + 18

Step-by-step explanation:

f(x) is x² + 3  

g(x) is 6x

(f o g) (x) means for all xs in f replace it with g(x) or 6x

(f o g) (x) = (6x)² + 3  - see 6x is in place of x and 6x is g(x)

(f o g) (x) = 36x² + 3

(g o f) (x)  = 6(x² + 3)  

(g o f) (x)  = 6x² + 18

The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is 35
Inessa [10]

35km; Since the points on the map are one millionth of their actual size, simply multiply by one million and convert from there.

35*1,000,000 = 35,000,000mm

35,000,000/1000 = 35,000m

35,000/1000 = 35km
