If it takes 5 builders hours to build a wall, it will take 2 builders hours to build an identical wall
The time taken for 5 builders to build the wall = hours
The time take for 5 builders to build the wall = 3.5 hours
Time taken for 1 builder to build an identical wall =
5 x (Time taken for 5 builders to build the wall)
Time taken for 1 builder to build the wall = 5 x 3.5
Time taken for 1 builder to build the wall = 17.5 hours
Time taken for 2 builders to build an identical wall = (Time taken for 1 builder)/2
Time taken for 2 builders to build an identical wall = 17.5/2
Time taken for 2 builders to build an identical wall = 8.75 hours
Time taken for 2 builders to build an identical wall = hours

Answer: 7
Step-by-step explanation:
Let the number chosen by Michael be x.
We are told that he multiplied it by itself, added 1. This would be:
= = ( x × x) + 1 = x² + 1
We are further told that he multiplied the result by 10, and added 3. This would be:
= = [(x² + 1) × 10] + 3
= 10x² + 10 + 3
= 10x² + 13
Lastly, he multiplied the result by 4 and his final answer was 2012. This would be:
(10x² + 13) × 4 = 2012
40x² + 52 = 2012
40x² = 2012 - 52
40x² = 1960
x² = 1960/40
x² = 49
x = ✓49
x = 7
The number is 7
can be expressed as:
= ( x × x) + 1 = x² + 1

Answer:
daily interest rate is 3.717%
monthly interest rate is 3.712%
Step-by-step explanation:
We are given
APR=3.65%
We can use formula
where
EAR is effective interest rate
APR is annual interest rate
m is number of periods
(a)
For daily:
APR=3.65%=0.0365
m=365
so, we can plug this value
So, daily interest rate is 3.717%
(b)
For monthly:
APR=3.65%=0.0365
m=12
so, we can plug this value
So, monthly interest rate is 3.712%
