Answer:
Jina will have enough money to buy the bike in 15 weeks
Step-by-step explanation:
y = mx + b
198 = 9x + 63
Subtract 63 from both sides;
135 = 9x
Divide both sides by 9;
x = 15
In this question , we have to simplify the given ratio, which is
12xy:3x
First we have to see which factor is common in numerator and denominator,
We can write 12 as 3 times 4, that is
![3*4x*y :3x](https://tex.z-dn.net/?f=%203%2A4x%2Ay%20%3A3x%20)
So the common factor is 3x.
In the next step, we cancel out 3x
![4y:1](https://tex.z-dn.net/?f=%204y%3A1%20)
And that's the required simplified form .
Answer:
![\dfrac{\text{kg}\cdot\text{m}^2}{\text{s}^3}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bkg%7D%5Ccdot%5Ctext%7Bm%7D%5E2%7D%7B%5Ctext%7Bs%7D%5E3%7D)
Step-by-step explanation:
Power (denoted by P) can be defined as a function of work (denoted by W) and time (denoted by t) using this formula:
![P=\dfrac{W}{t}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BW%7D%7Bt%7D)
Unit of Work = ![\dfrac{\text{kg}\cdot\text{m}^2}{\text{s}^2}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bkg%7D%5Ccdot%5Ctext%7Bm%7D%5E2%7D%7B%5Ctext%7Bs%7D%5E2%7D)
Unit for Time = s
Therefore, the Unit of Power
![=$Unit for W \times \dfrac{1}{\text{Unit for time}}](https://tex.z-dn.net/?f=%3D%24Unit%20for%20W%20%5Ctimes%20%5Cdfrac%7B1%7D%7B%5Ctext%7BUnit%20for%20time%7D%7D)
![=\dfrac{\text{kg}\cdot\text{m}^2}{\text{s}^2} \times \dfrac{1}{s} \\=\dfrac{\text{kg}\cdot\text{m}^2}{\text{s}^3}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Ctext%7Bkg%7D%5Ccdot%5Ctext%7Bm%7D%5E2%7D%7B%5Ctext%7Bs%7D%5E2%7D%20%5Ctimes%20%5Cdfrac%7B1%7D%7Bs%7D%20%5C%5C%3D%5Cdfrac%7B%5Ctext%7Bkg%7D%5Ccdot%5Ctext%7Bm%7D%5E2%7D%7B%5Ctext%7Bs%7D%5E3%7D)
An appropriate unit for power is: ![\dfrac{\text{kg}\cdot\text{m}^2}{\text{s}^3}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bkg%7D%5Ccdot%5Ctext%7Bm%7D%5E2%7D%7B%5Ctext%7Bs%7D%5E3%7D)
