Not all square roots are irrational. This can be proven by finding the perfect square roots. The sqrt. of 16, 25, and 26, for example, the answers are all rational numbers.
I hope this is what you are asking for; let me know if you need anythings else :)
Number of tiles used for
covering the kitchen floor = 10
Area covered by the floor = 6
* 5 feet^2
<span><span>
= 30 square feet</span>
</span>
Length of each tiles = 3 feet
Width of each tiles = w feet
Area covered by each tiles = 3w square feet
Then the equation can be written as
3w * 10 = 30
30w = 30
w= 30/30
<span>
= 1 feet</span>
So the width of each tiles is 1 feet.
I hope the procedure is clear enough for you to understand. The equation to determine the solution is
10 *3w = 30
There are 10 tiles used and the area covered by each tiles is 3w. Also the area of the floor is 30 square feet. All those information's have been used to get to the equation.
Answer:
THe expected annual cost is $282200
Step-by-step explanation:
We should take the base cost and sum it by the anual cost multiplied by 3, because the lifetime of the machines is 3 years. Since the expected return is 10%, then we have to multiply the result by 1.1, therefore
cost = (750000+12000*3)*1.1 = $864600
Now, we divide this by 3 to obtain the annual cost
Annual cost = 864600/3 = $288200
Answer:
Yes
