Answer:
see explanation
Step-by-step explanation:
Using cross- products, that is
= 
then ad = bc
Given the ratios
and 
Then equating and using cross- products
If both sides equate then the ratios are equivalent
= , then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent
17 minutes
In order to solve this you make a porportion:
24/12=34/x
You do (34×12)÷24
34×12=408
408÷24=
17

Answer:
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).
Ordering tickets online cost $10 plus additional service charge of $8.
Therefore total cost,C = 10t + 8
Buying tickets at the door cost $12
Therefore, total cost,C = 12t
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Answer:
D
Step-by-step explanation:
Sinusoid graphs look like regular waves.
It is obvious that only I and III look like waves.
II is known as a stepwise function.
