Answer:
Therefore the mass of the object is 56.78 kg.
Step-by-step explanation:
Mass: Mass of an object is physical property.Mass of an object can't change with respect to place.
The S.I unit of mass is Kg
But the weight of an object changes with respect to place.
Weight= mass× gravity
The gravitational force varies place to place.
For this reason the weight of an object is not constant.
The value of g is 9.8 m/s².
Unit of weight:
Weight = mass × gravity
=Kg×m×s⁻²
=N
Given, weight= 557 N , g= 9.81 m/s² and mass=?
Weight = mass × gravity
⇒557= mass× 9.81
![\Rightarrow mass=\frac{557}{9.81}](https://tex.z-dn.net/?f=%5CRightarrow%20mass%3D%5Cfrac%7B557%7D%7B9.81%7D)
⇒mass= 56.7787≈56.78
Therefore the mass of the object is 56.78 kg.
Answer:
This is a ratio problem
Since we know 4.75 inches equals 75 miles, we can find what small unit of a inch correlates to 75 miles, and then use that data to find the other answer. To do this, we divide 75 miles by 4.75 inches. We get 16 as an estimate (15.789 to 16). Knowing this, we can multiply 16 to 6.25 and get 100 miles. 100 miles is the answer

The first is a. you can rewrite it
![\sqrt{x^5} = \sqrt{x^2x^2x} = \sqrt{x^2}\sqrt{x^2}\sqrt{x} = xx\sqrt{x} = x^2\sqrt{x}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%5E5%7D%20%3D%20%5Csqrt%7Bx%5E2x%5E2x%7D%20%3D%20%5Csqrt%7Bx%5E2%7D%5Csqrt%7Bx%5E2%7D%5Csqrt%7Bx%7D%20%3D%20xx%5Csqrt%7Bx%7D%20%3D%20x%5E2%5Csqrt%7Bx%7D%20)
the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined
the third is c.
![\sqrt{36x} + \sqrt{100x} - \sqrt{25x} \\ 6\sqrt{x}+10\sqrt{x}-5\sqrt{x} \\ 11\sqrt{x}](https://tex.z-dn.net/?f=%5Csqrt%7B36x%7D%20%2B%20%5Csqrt%7B100x%7D%20-%20%5Csqrt%7B25x%7D%20%5C%5C%206%5Csqrt%7Bx%7D%2B10%5Csqrt%7Bx%7D-5%5Csqrt%7Bx%7D%20%5C%5C%2011%5Csqrt%7Bx%7D%20)
the fourth is d.
add 3 to both sides
![\sqrt{2x} = 10](https://tex.z-dn.net/?f=%5Csqrt%7B2x%7D%20%3D%2010)
then square both sides
![2x=100](https://tex.z-dn.net/?f=2x%3D100)
then divide both sides by 2, x=50
