First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 = 2112 feet
2x - 10 = 30
2x = 40
x = 20
Your answer is 4/14 or 2/7. There are two possibilities when you flip a coin, heads or tails. Then for the spinner there are 7. Multiply them by each other to get the total number of outcomes of the situation of 14. Then there are only 4 odd numbers from 1-7. This means that you would only be able to get an odd number and heads 4 times.
Hope this helped!
Answer:
I think it's D
Step-by-step explanation:
because you can get an output if you input any numbers
Answer:
30
Step-by-step explanation:
use Pythagoras theorem
hypothenuse of bottom triangle =√24^2+32^2 = 40
x =√50^2-40^2 = 30
