Answer:
4 pounds and 1/4 ounces
Step-by-step explanation:
8 and 1 half pounds = 8.5 Ibs
One half of 8.5 = 8.5/2 = 4. 25 Ibs or 4 & 1/4 or 4Ibs 4 ounces.
example
the square root of 16 is 4
the square root of 9 is 3

Answer:
15 blue marbles
Step-by-step explanation:
Given that:
A bag contains 6 red marbles.
The Ratio of red to blue marbles is 2:5
Thus, the ratio of red marbles for 6 red marbles in a bag will be = 6/2 = 3
Now; the ratio of blue marbles in a bag containing 6 red marbles = 3 × 5 = 15 blue marbles
OR
Mathematically;
![\dfrac{2}{5} \times \dfrac{x}{x} = \dfrac{6}{blue}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7Bx%7D%7Bx%7D%20%3D%20%5Cdfrac%7B6%7D%7Bblue%7D)
So, we are looking for the same number we can multiply for both the numerator and the denominator that can give us the value of 6 in the above numerator to determine the value of the denominator. If we use 3 since 2× 3 = 6
We have:
![\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{blue}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B3%7D%20%3D%20%5Cdfrac%7B6%7D%7Bblue%7D)
![\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{15}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B3%7D%20%3D%20%5Cdfrac%7B6%7D%7B15%7D)
So, there are 15 blue marbles in the bag.
If something is to the power of 1/2, it is the same as the square root of that number. So, what's the square root of 49?
