Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
Answer:
M = -4
Step-by-step explanation:

When the exponent is negative, you have to make the number a fraction(1 over the number).
For example:


This gets rid of the negative, but it leaves the exponent

When an exponent is a fraction, it is the square root.
For example:
![x^{\frac{1}{3}} = \sqrt[3]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D)

![x^{\frac{1}{4}}=\sqrt[4]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7Bx%7D)
So...

Answer:
A. The twelve-pack is better because each soda cost $0.25
Step-by-step explanation:
12 x 0.25 = $3.00 which is only like a buck and 25 cents more for 6 more orange juices.
In the market, you would buy the 12 pack because $1.25 is less than 6 more orange crushes. Also, it's a solid deal and the rate is not pricey! :)
