Answer:
C) 49 inches
Step-by-step explanation:
C = 2 π r
308 = 2 (22/7) r
308 = 44/7 r
49 in = r
Answer:
A=80 square feet.
Step-by-step explanation:
Let's put it into perspective.
x/(x+5)
If increase by 3:
(x+3)/(x+8) = 3/4
Cross multiply.
4(x+3)=3(x+8)
4x+12 =3x+24
Solve algebraically.
4x-3x = 24-12
x = 12
Therefore, original fraction is:
12/17
Answer:
Triangle ABC is similar to triangle A prime B prime C prime., because Triangle A prime B prime C prime. is obtained by dilating Triangle ABC. by a scale factor of 1 over 2. and then rotating it about the origin by 180 degrees
Step-by-step explanation:
Step 1: Dilation by a scale factor of 1/2.
A point (x, y) is sent to (1/2 x, 1/2 y).
A(2, 2) ---> (1, 1)
B(2, 10) ---> (1, 5)
C(8, 12) ---> (4, 6)
Step 2: Rotate about the origin 180 degrees
A point (x, y) is sent to (-x, -y).
(1, 6) ---> A'(-1, -1)
(1, 5) ---> B'(-1, -5)
(4, 6) ---> C'(-4, -6)
