Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as 
then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × 
= 1.75 × 18 = 31.5
Answer:
b
Step-by-step explanation:
The answer to your problem is going to be that there is a total of 432 seats in each movie area. you get this by multiplying 18 and 24 together. this is because there is 24 seats in each of the 18 rows. it is the same as finding the area of a rectangle, length * width.
Answer: 0
Step-by-step explanation:
describes a horizontal line
so slope = 0
Multiply the length of the model by 10
18.5* 10 = 185 inches
