Let C and d be the circumference and diameter of a circle, respectively. Then
C = πd
so that
π = C/d = C/12
Answer:
7n^2
Step-by-step explanation:
Multiply 8/n by 7n/7n to get 56n/7n^2
Answer:
1/204.
Step-by-step explanation:
That would be
6/18 * 5/17 * 4/16 * 3/15
= 1/3 * 1/4 * 1/5 * 5/17
= 5/1020
= 1/204.
Answer:
A. a = 10
B. m<FNT = 120°
C. m<KTU = 60°
Step-by-step explanation:
A. (7a + 50)° and (14a - 20)° are corresponding angles. Therefore:
(7a + 50)° = (14a - 20)°
Use this equation to find the value of a
7a + 50 = 14a - 20
Combine like terms
7a - 14a = - 50 - 20
-7a = -70
Divide both sides by -7
-7a/-7 = -70/-7
a = 10
B. m<FNT = (14a - 20)° (alternate interior angles are congruent)
Plug in the value of a
m<FNT = 14(10) - 20
m<FNT = 140 - 20
m<FNT = 120°
C. m<KTU + (14a - 20)° = 180° (linear pair)
Plug in the value of a
m<KTU + 14(10) - 20 = 180
m<KTU + 120 = 180
m<KTU + 120 - 120 = 180 - 120
m<KTU = 60°
