Answer:
C) The total number of about uniforms needed is 60 x 80 uniforms.
Step-by-step explanation:
The Number of total stores the owner has = 64 stores
The number of employees uniform needed in 1 store = 79 uniforms
Now, 64 is Rounded off to about 60.
and 79 is Rounded off to about 80.
⇒ The total number of uniforms in 60 stores = 60 x ( uniform in 1 store)
= 60 x (80 uniforms)
or, the expression of total uniforms needed = 60 x (80 uniforms)
Hence, the total number of about uniforms needed is 60 x 80 uniforms.
7. What I did is divide 520 by 8 to get the miles and hour. I got 65. Since you can get 65 miles and hour, i divided 455 by 65 to get 7.

"Cross multiply."

Answer:

Step-by-step explanation:
Given that,
The pH of the solution = 12.24
We need to find the H⁺ concentration of the solution. We know that,
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
Put pH = 12.24
So,
![12.24=-log[H^+]\\\\\[H^+]=4.83\times 10^{-6}](https://tex.z-dn.net/?f=12.24%3D-log%5BH%5E%2B%5D%5C%5C%5C%5C%5C%5BH%5E%2B%5D%3D4.83%5Ctimes%2010%5E%7B-6%7D)
So, the concentration of H+ is
.
