Answer: 3.3
Step-by-step explanation: maximum was 250 yards and each pool is 75 yards, how many pools did he use? divide the 250 by 75 which you should've gotten 3.33333333333. round to the nearest tenth.
It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30
The square is 130 in squared and the other shape is 54 in squared. If you're looking for the sum of the whole thing, its 185 in squared.
square: 13*10=130
triangle: 7*4= 28/2=14
rectangle: 10*4=40
I think it’s y = 10x + 10
Use this systems of equations to solve:
x = first antifreeze
y = second antifreeze
Isolate y.
x + y = 15
Subtract x from both sides.
y = -x + 15
Substitute y into the other equation.
.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25
Substitute x in the equation that we isolated y in.
y = -11.25 + 15
y = 3.75
11.25 L of the first antifreeze and 3.75 L of the second.
