#2 is 35°C (just plug in 95 to the formula)
#3:
in the left column are:
(8x-(6+y))
(3/4)w+x^2
in the right column are:
y^2-0.5w
w/4+3(x+y)
to solve you just plug in to the formula
Answer:
-1
Step-by-step explanation:
5^(3b-1) = 5^(b-3)
3b-1=b-3 / +1 -b
2b = -2
b = -1
50 girls attended the trip. ( 80 boy + 50 girls = 130 total students) You just multiply both by 10.
If a 12 gallon tank is filled with water at rate of 1/4 of the tank in 5 seconds, then it's filled with 3 gallons per 5 seconds (because 1/4 * 12 = 3). 5/6 of the tank is as much as 5/6 * 12 = 5 = 60/6 = 10 gallons.
If 3 gallons of the tank are filled in 5 seconds, then 10 gallons will be filled in (10 ÷ 3) * 5 = 3 1/3 * 5 = 16 2/3 seconds.
Answer: It will take 0 minutes and 16 2/3 seconds to fill 5/6 of the tank.
I hope that's what you meant :)
