Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.
Step-by-step explanation:
When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A= so we plug in our known variables...
we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.
r=9
A=
A=81
A=254.469
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to call the numbers x and y.
A number is equal to twice a smaller number plus 3.
Greater number is x, and smaller is y. So
The same number is equal to twice the sum of the smaller number and 1.
This means that
Equaling the values for x:
Since division by 0 does not exist, it means that there is no solution for the system.
