Move the decimal to the right twice to make this into a percent:
1.03 —-> 103%
Answer:
3 can go into 77 25 times.
5)
Equilateral triangle, all sides are equal
So 2x + 5 = 11
2x = 6
x = 3
Answer is the first one
3; Equilateral theorem
6)
Isosceles triangle has at least two congruent sides.
So 6x = 24
x = 4
Answer x = 4
Converse of the Base Angle Theorem
7)
5x + 7 = 52
5x = 45
x = 9
Answer
x = 9
Base angle theorem
8)
5y - 14 = 3y
2y = 14
y = 7
Answer
7; Equiangular theorem
You would do pi x r squared. r=12, and 12 squared is 144. pi (3.14) times 144 equals 452.16!
14 ÷ 1/2 × 3 (I hope it's right. I would have done this)
