Step-by-step explanation:
0.89 = 1 - 1/(k²)
Start by subtracting 1 from both sides:
0.89 - 1 = -1/(k²)
-0.11 = -1/(k²)
Multiply both sides by -1:
0.11 = 1/(k²)
Multiply both sides by k²:
0.11 k² = 1
Divide both sides by 0.11:
k² = 1 / 0.11
Take the square root:
k = √(1 / 0.11)
Answer:
The answer is 4 and 3/4 or 4.75.
Step-by-step explanation:
1/2 + 1/2 is equal to 1
1/4 is the same thing as 2/8 so we have four eights
3/8 is six eights since we have two on the number line
5/8 x 3 is about 1.875
7/8 is just 7/8 because there is only 1 on the number line.
add all of these fractions together and you will end up with about 4 and 3/4
