Answer:
9 meters
Step-by-step explanation:
Area of a parallelogram is base * height.
A = b * h
65.7 = b * 7.3
b = 9 meters
Answer:
134 kilometers or 83 miles.
Explanation:
First make all the units equivalent, so
60 km/h = 60 km/h or 37.28 m/h
45 m/h = 72.42 km/h or 45 m/h
50 km/h = 50 km/h or 31.07
So in one hour the car has gone 60 km or 37.28 m because they travel at 60km/h, which means they get that far in that amount of time.
In half an hour they get half of 45 miles, because 45 m/h means they get 45 miles in 60 minutes, so in 30 minutes, or half and hour, they are getting half of 45 = 22.5 miles or 36.21 kilometers.
In 45 minutes they are getting 75% of 50 km because 45 minutes is 75% of an hour. So 75% of 50 is 37.5 km or 23.3 miles.
Add this all together and get:
Kilometers:
60 + 36.21 + 37.5 = 133.71 km
Miles:
37.28 + 22.5 + 23.3 = 83.08 m
133.71 km = 83.08 So it checks out.
This is approximately 134 km or 83 miles.
Answer:12 miles per hour
Step-by-step explanation:
60miles/5hours =12 miles per hour
Answer:
4:3 would be the ratio in its simplified form.
Answer:
Step-by-step explanation:
Let f(x) be the polynomial.
If x=-3, x=0,x=0, x=1 are roots ,then by the factor theorem, x+3=0,x=0,x=0, x+1=0 are factors of f(x).
This implies that:
