Answer:
Percent is 40%
the decimal is .40
Step-by-step explanation:
1/5 = 20%/.20
So if 1/5 is 20% 2/5 should just have 20% more resolving in 40% or .40
Answer:
Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Step-by-step explanation:
Speed = distance / time
Speed*time = distance
Assuming that Megan travelled x hours at 9mph
(9*x) + (7*(9-x)) = 75
x = 6 hours
So Megan travelled at 9mph for 6 hours and 7mph for 3 hours
For range it’s highest number minus lowest number so:
28 - 21 = 7
For median it’s the middle number:
Since there’s two we add them and dive it by two so:
25 + 24 = 49 dived by 2 = 24.5
For mode it’s most occurring number in this case :
All of them appear twice so none of them are the mode
Answer:
1/10 is the simplest form
To write this expression as a positive exponent we use this rule of exponents: xa=1x−a. 5−3=15−−3=153. Use this rule for exponents: xa=1x−a. 5−3=15−−3=153=1125.
