Answer:
45 cookies
Step-by-step explanation:
Use a unit rate.
With a unit rate, we find the number of cookies that are baked using 1 scoop.
(30 cookies)/(6 scoops) = 5 cookies/scoop
The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.
Now we multiply the unit rate by 9 scoops.
9 scoops * 5 cookies/scoop = 45 cookies
Answer: 45 cookies
Answer:
Rate = 108 km/hr
Distance travelled in 2 hours = 216 km
Step-by-step explanation:
A car is travelling at a rate of 30 meters per second
1 km = 1000 meters
? km = 30 meters
Cross multiplying gives; km
1 hr = 3600 seconds
? hrs = 1 second
Cross multiplying gives; hrs
Speed = Distance ÷ Time
Speed in km/hr = km ÷ hrs = km × = 108 km/hr
Distance travelled in 2 hours = 2 × 108 km = 216 km
Prime numbers are only divisible by 1 or itself; the first few are are 2, 3, 5, 7, and 11.
