Answer:
4.2
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
Suppose x = 0.83 (3 repeating).
Multiply both sides by 10:
10x = 8.3 (repeating 3)
Now, multiply both sides by 10 again:
100x = 83.3 (repeating 3)
So, we have:
100x = 83.3 (repeating 3)
10x = 8.3 (repeating 3)
We see that if we subtract these two equations, the repeating 3s cancel out, and we're left with:
100x - 10x = 83 - 8
90x = 75
x = 75/90 = 5/6
Thus, the answer is 5/6.
Hope this helps!
Answer:
A
Step-by-step explanation:
Simplify both sides x+38.18=82.06
subtract 38.18 from both sides
x+38.18-38.18=82.06-38.08
x=43.88
Answer:
-18
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Since the figure was not supplied, let's focus on that principle.
To calculate it simply subtract the area of the square minus the area of the circle. Given the side of the square 20 ft
1. Square Area
2.Circle Area
Notice the radius is half the square side, i.e. 10 ft
Subtracting the area of the square and the area of the circle:
