Answer:
5.83
Step-by-step explanation:
816/850x100 = 96
Therefore 96 % of tickets were sold.
11 because it cannot be divided by any whole number besides 1.
Answer:

The least number 12500 need to be multiplied by to make it a perfect square is 5.
Corrected question;
By which least number should 12500 be multiplied to make them perfect squares
Step-by-step explanation:
Perfect squares are squares of whole numbers.
Like 4,9,16 etc.
For 12500, we need to first of all reduce it to its Lowest factors.
12500 = 2×2×5×5×5×5×5
Grouping the factors into pairs of thesame factors.
12500 = (2×2) × (5×5) × (5×5) × 5
Looking at the pairs of factors, we can observe that the last factor 5 need to be paired to make the number a perfect square.
So, when the number is multiplied by 5;
12500 × 5 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×5×5×5)^2 = 250^2
Hence, 62500 is a perfect square.
The least number 12500 need to be multiplied by to make it a perfect square is 5.
Answer:
Solution is : x = 1 ± 0.5√3
Step-by-step explanation:
We have given quadratic equation:
4x² - 8x + 1 = 0
We need to find solution using quadratic formula.
i.e x = 
Compare from general quadratic equation ax² + bx + c=0
Here a= 4 , b = -8 and c = 1
∴ x = -(-8)±√((-8)²-4·4·1) / 2·4
x = (8 ±√48 )/8
x = 1 ± 0.5√3 , This is the answer
