Answer:19
Step-by-step explanation: 380 divide by 20 is 19
give me brainliest please
So she earned 84 total dollars
she earned 14 dollars mowing lawns
she earned (total-mowing lawns=babysitting) 84-14=70 dollar babysitting
7 dollars per hour so
70/7=10 so
h=10
PART A :OK so here is the table for the health inspector; all you are really doing is 7+7+7, and so on:
PART A: health inspector: 7,14,21,28,35,42,49,56,63,70,77,84..........
PART A:same thing for the fire inspector, except this time your adding 12+12+12, and so on:
PART A: fire inspector: 12,24,36,48,60,72,84,96.......
PART B: and to figure out what day they will both come is you have to find the LCM (least common multiple)
PART B: which in this case is Day 84
hopes this helps!!!!!
Simple...
you have:
![F= \frac{G m^{2} }{ d^{2} }](https://tex.z-dn.net/?f=F%3D%20%5Cfrac%7BG%20m%5E%7B2%7D%20%7D%7B%20d%5E%7B2%7D%20%7D%20)
You want to find m-->>>
1.)Isolate m
![d^{2} *F= \frac{G m^{2} }{ d^{2} } * d^{2}](https://tex.z-dn.net/?f=%20d%5E%7B2%7D%20%2AF%3D%20%5Cfrac%7BG%20m%5E%7B2%7D%20%7D%7B%20d%5E%7B2%7D%20%7D%20%2A%20d%5E%7B2%7D%20)
Leaving you with...
F*
![d^{2}](https://tex.z-dn.net/?f=%20d%5E%7B2%7D%20)
=
![G m^{2}](https://tex.z-dn.net/?f=G%20m%5E%7B2%7D%20)
Keep isolating m-->>>
![F* d^{2} =G m^{2}](https://tex.z-dn.net/?f=F%2A%20d%5E%7B2%7D%20%3DG%20m%5E%7B2%7D%20)
![\frac{F* d^{2} }{G} = \frac{G m^{2} }{G}](https://tex.z-dn.net/?f=%20%5Cfrac%7BF%2A%20d%5E%7B2%7D%20%7D%7BG%7D%20%3D%20%5Cfrac%7BG%20m%5E%7B2%7D%20%7D%7BG%7D%20)
Square root to solve what just m is-->>>
![\sqrt{ \frac{F* d^{2} }{G} } = \sqrt{ m^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7BF%2A%20d%5E%7B2%7D%20%7D%7BG%7D%20%7D%20%3D%20%5Csqrt%7B%20m%5E%7B2%7D%20%7D)
=
![\sqrt{ \frac{F* d^{2} }{G} } =m](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7BF%2A%20d%5E%7B2%7D%20%7D%7BG%7D%20%20%7D%20%3Dm)
That is how you solve for m...
Thus, your answer.
