If this answer is correct, please make me Brainliest!
Answer:
First answer.
Step-by-step explanation:
This is called the Arc length, here is the formula:
Arc length = (angle/360)*(2Pi*radius)
So,
(45/360)*(2*3.14*4)
= 3.14
SO Pi !!!!!
Answer:
may be 13 I hope this is the right answer
Answer:
8/3
Step-by-step explanation:
i put equations as this:
x+40 = y
where x is galllons of pure mixture and y is the gallons of the new mixture
the other equation i id was:
x+0.2(40) = 0.25y
x+8 = 0.25y
y = 4x+32
solve using substitution
(x+40) = 4x+32
x = 4x-8
-3x = -8
x = 8/3
Answer:
Equations are composed for many expressions.
Expressions can indicate variables, constants, etc.
