Answer:
A= 30
Step-by-step explanation:
A= a+b over 2
h= 5+15 over 2 times that by 3 to get 30
Given the equation :
We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :
Log_10 100 is the same as 10 to the x power is 100
10^x=100
10^2=100
the answer is 2
