Answer:
yards
Step-by-step explanation:
The circumference of this circle = 2πr
= 8π
We have to find the arc length of 50°, or 50/360 times the circumference of the circle(because there is 360° in a circle)

<u>Solution-</u>
Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)
1 UK gallon = 4.5459631 lit
1 US gallon = 3.7853060 lit


As the fuel consumption rate = 40 miles per gallon
⇒ You need 1 UK gallon of fuel to go 40 miles
⇒ You need 1.2009499 US gallon of fuel to go 40 miles
Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel
⇒ To go 1 mile you will need 
⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel
∴ 22.1574906 gallon of fuel is actually required.
∴ But, what she thinks will require is
(As she calculated using UK gallons)
Answer:
s = 10k + 30
Step-by-step explanation:
Cost of Adults ticket = $10 per adult
Cost of Ticket = $6 per child
Number of adults = k
Number of Children = 5
s = Total cost
Total cost = (Cost per adult * number of adults) + (Cost per child * Number of children)
s = ($10 * k) + ($6 * 5)
s = $10k + $30
s = 10k + 30
