A = √(15²-9²) = √(225-81) = √144 = 12
Answer:
20% tip is $3.97, add that to 18.97 and you get $22.76, then add 8.25 and you get $31.01
X^2 + 9 + 7 = 20
X^2 +16 = 20
X^2 = 20-16
X^2 = 4
Root 4 = 2
X=2
Diameter = 2*radius
14/2=7
Radius is 7in"
Circumference of circle formula: 2pi(radius)
2pi(7)= 43.98in of wire required so it can wrap around lamp exactly once.
Answer:
opposite sides of ||gram are equal and parallel therefore
