Answer:
1.79553
Step-by-step explanation:
Step 1: Write expression
log₁₀(√(69.5² - 30.5²))
Step 2: Evaluate square root
log(√(4830.25 - 930.25))
log(√3900)
log(62.45)
Step 3: Find log
log₁₀ (or log)
log(62.45) = 1.79553
-------------------------------------
To use the table method. we find values that are easily evaluated by log₁₀
log₁₀(10) = 1
log₁₀(50) = 1.69897
log₁₀(100) = 2
So we know that log₁₀(62.45) is between 1 and 2 and greater that 1.69897.
It would be 50.24 ft
BTW in this case I used 3.14 for pi
Answer:
Average = 16, standard deviation =
Step-by-step explanation:
15+12=27
27+(17+14)+22=27+31+22=80
80/5=16
Distance from 22 to 16=6, from 12 to 16=4, so deviation = 5
Answer:
It rotates 50 times a second
Step-by-step explanation:
There is 60 seconds in a minute,so all you have to do is Divide 30,000 by 60 and you get 50!
Answer:
10 miles in 50 minutes
Step-by-step explanation:
1. Divide 20 into 4 to see the unit rate of 1 mile.
2. If you continue on from 20 to 50 you will notice it will be 10 miles.
You welcome.
