Answer:
y = 5x + 6
Explanation:
we need to things to do this, the slope and the equation of a line
slope = change in y/ change in x
change in y = (-4 - 1) = -5
change in x = (-2 - -1) = -1
-5/-1 = 5
y = 5x + b
plug in a point
1 = 5(-1) + b
b = 6
y = 5x + 6
Mark's dog ran 3 4 of a mile in 1 4 of an hour. Compute the unit rate from the complex fraction 3 4 1 4 miles per hour.
Answer:
4.13×10^22 atoms
Explanation:
1. Find number of moles
mole=mass/rmm of compound
mole= 3.50/102
mole= 7/204 mol
2. Multiply it with avagadros constant( 6.02×10^23 particles)
7/204 × 6.02×10^23= 2.0657×10^22
3. Multiply it with the number of ALMINIUM ATOMS IN AL203( which is 2 atoms)
2.0657×10^22 × 2
you get 4.13×10^22 atoms
