Answer:
1.4 mol
Step-by-step explanation:
2NaOH + H2SO4 -----> Na2SO4 + 2H2O
from reaction 2 mol 1 mol
given 2.8 mol x
x = (2.8*1)/2 = 1.4 mol
4x+10 + 3x+5 +y =180
solve for y y=third angle
combine like terms
7x+15+y =180
subtract 7x+15 from each side
y = 180 -(7x+15)
y = 180 -7x-15
y = 165 -7x
The third angle equals 165-7x
Answer:
r = $105.6
Step-by-step explanation:
Given,
Amount paid by Trevor for 4 nights = $528
Rate per day = r
Now,
We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.
Now,
Amount paid = Number of days x Rate per day
$528 = 5 r
r = $105.6
Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.
((5m)^2) + ((m^2)+(5^2))
The wording is a bit weird, but that's what I got.
The length would be 36
12 times 3=36
8 times 3=24
Otherwise it would be 27
