The answer is 2z-10. Hope it helps.
Answer:
a = 17 sqrt(2)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite / hypotenuse
sin 45 = 17/a
Multiply each side by a
a sin 45 = 17
Divide each side by sin 45
a = 17 / sin 45
a = 17 / ( 1 / sqrt(2))
a = 17 sqrt(2)
Answer:
60ml of the 50% alcohol solution and 20ml of the 6% alcohol solution
Step-by-step explanation:
We can build a system of equation for solve this problem
x = first solution
y = second solution
x + y = 80
0.5x + 0.06y = 80 * 0.39
x + y = 80
0.5x + 0.06y = 31.2
x = 80 -y
0.5(80-y) + 0.06y = 31.2
40 - 0.5y + 0.06y = 31.2
-0.44y = -8.8
y = 20
x = 80 - 20 = 60
Answer:
2/3 gallons
Step-by-step explanation:
Given data
We have the following data
1/2 gallons is the same as 0.5 gallons
hence 0.5 gallons will cover 3/4 of his deck
x gallons will cover 1 of his deck
cross multiply we have
3/4*x = 0.5*1 gallons
3x/4= 0.5
3x= 2
divide both sides by 3
x= 2/3
Hence 2/3 gallons will cover the entire deck
