Let's assume, for simplicity, that there were 100 questions in the test: a score of 80% means you got 80 right and (100-80)=20 wrong.
The ratio is then 80 to 20 or
80:20.
you can also simplyfy it, by dividing both numbers by 20:
4:1
which I think is the best way to give the answer!
a truck can travel 160 miles in the same time that it takes a car to travel 200 miles. If the truck's rate is 10 miles per hour slower than the car's find the average rate for each.
the rate of the car is miles per hour
Answer:
= 186 F
136 F is taken as the steam point
-50 F is taken as the ice point
∴ difference = steam point - ice point
= 136- (-50)
= 186F
i think it might be ![\sqrt[5]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B3%7D)
but im not sure
