I think it’s 2,000 but again I could be wrong I need like the options
<h3>Answers: </h3><h3>Use <u>60 gallons</u> of the 30% solution</h3><h3>Mix with <u>40 gallons</u> of the 80% solution</h3>
===============================
Work Shown:
x = amount of the 30% solution (in gallons)
y = amount of the 80% solution (in gallons)
The two amounts must add to 100 as this is the total we want, so x+y = 100 which becomes y = 100-x after subtracting x from both sides
The expression 0.30*x represents the amount of pure alcohol from the first batch, while 0.80*y represents the amount of pure alcohol from the second batch. In total, we have 0.30*x+0.80*y gallons of pure alcohol. We want 50 gallons of pure alcohol (50% of 100 gallons is 50 gallons), therefore we end up with this equation: 0.30*x+0.80*y = 50
Let's use substitution to isolate the variables.
0.30*x+0.80*y = 50
0.30*x+0.80*(100-x) = 50 ... replace y with 100-x
0.30*x+0.80*(100)+0.80*(-x) = 50 ... distribute
0.30*x+80-0.80x = 50
-0.50*x+80 = 50
-0.50*x+80-80 = 50-80 ... subtract 80 from both sides
-0.50*x = -30
x = -30/(-0.50) .... divide both sides by -0.50
x = 60
If x = 60, then y is...
y = 100-x
y = 100-60
y = 40
I searched that in my math book dictionary and i found out that adjacent angles are two non-overlapping angles that share a vertex and a side
Answer:
64868 feet
Step-by-step explanation:
The deepest point as a negative 35,840 feet mark
The tallest point has a positive 29,028 feet mark
<u>The difference between them:</u>
- 29,028 - (-35,840) = 64,868 feet
<u>Answer is</u> 64,868 feet
it is a because it is the line is in the spot we're it is ststop to go
