Answer:
85 miles to feet is 448,800 feet :)
Step-by-step explanation:
Answer:
r = 67.70 feet
Step-by-step explanation:
Area of circle, A = πr²
where r is the radius and π = 3.142
A = πr²
r² = A / π
r = √(A / π)
r = √(14400 / 3.1042)
r = √(4583.66)
r = 67.70 feet
-(4 1/5)
5(4)+1 = 21
Thus the answer would be -21/5
Answer:
x=136
Step-by-step explanation:
The sum of the angles inside a quadrilateral add to 360, so
79+55+110+x=360
Combine like terms
224+x=360
Subtract 224 from both sides
x=136
The answer is x= 2, y = 6
Solve for y in the second equation, so you have y= -3x + 12. Now plug that in for y in the first equation: 5x + 3( -3x +12) = 28.
Now simplify: 5x + -9x + 36 = 28: -4x = -8; so x = 2.
Now plug x=2 into either equation to solve for y:
3(2) + y = 12; 6 + y = 12; so y = 6
