2 tens, and 8 ones. I say this because 20 = 10 + 10 so, two tens. 8= 1+1+1+1+1+1+1+1 so, eight ones.

Help me out please. i need to find the function rule,

Replace x in the equations and see which one gets the matching y :

-5(0) = 0 +1 = 1

-5(1) = -5 + 1 = -4

-5(-1) = 5 +6 = 6

The first equation works.

sam makes some bread rolls. He gives 2/5 of the bread rolls to his neighbor and 4/9 of the remainder to his cousin. He has fifte

FinnZ [79.3K]

Neighbor: 2/5(x) 
Remainder = x - 2/5(x) = 3/5(x) 
Cousin = 4/9 * 3/5(x) = 4/15(x) 

x - 2/5(x) - 4/15(x) = 15 
x - 6/15(x) - 4/15(x) = 15 
x - 10/15(x) = 15 
(15x - 10x) = 225 
5x = 225 
x = 225/5 = 45 

Therefore, he made 45 rolls

If you had carried out the algebra using variables before plugging numbers into your expressions, you would have found that (vf)

Answer:

Step-by-step explanation:

Volt is energy per electric charge

$1V=1J/C$

and the energy units in terms of meters, seconds and kilograms are:

$1J= 1kg\frac{m^{2}}{s^{2}}$

So the unit of volt is

$1V= kg \frac{m^{2}}{Cs^{2}}$

So the velocity expression (it can not be read completly) but i guess that it could be as follows

$vf_{a} = -2\sqrt{\frac{q_{a}\Delta V}{m_{a}}}$

So the unit analysis would be

$vf_{a} = \sqrt{\frac{C kg\frac{m^{2}}{Cs^{2}}}{kg}}}$

note that the coulomb unit of numerator is cancelled from the denominator. The same occurs for kg unit.

$vf_{a} = \sqrt{\frac{m^{2}}{s^{2}}}$

Applying square root

$vf_{a} = \frac{m}{s}$
