His speed is 8 miles an hour. 2/3 x 12/1 = 24/3 = 8
Answer:
that answer is false
Step-by-step explanation:
6 squared equals 36
8 squared equals 64
12 squared equals 144
so if you add 36 + 64 it only makes a hundred so 6 squared + 8 squared is not equal to 12 squared
Sue would have 21 dimes and 12 less of 21 is 9, so sue has 9 nickels
dimes: 21
nickels: 9
Answer:
20
Step-by-step explanation
use the formula a²+b²=c²
since a=21 and c=29 you need to solve for b
Put 21 in for a and 29 in for c
21²+b²=29²
21²=441
29²=841
so then the equation would be 441+b²=841
subtract both sides by 441
then you have b²=400
now just find the square root of 400
√b²=√400
b=20
