Answer:
Step-by-step explanation:
1 3/11=14/11
1 4/5=9/5
------------------
Because 1*11=11 and 11*3=14.
Because 1*5=5 and 5*4=9.
Answer:
Step-by-step explanation:
84 is twice 42
Multiply the numerator and the denominator of 42/50 by 2:
42/50 = (42×2)/(50×2) = 84/100
Let n and m be the sides of the kite
perimeter = 2(m+n)
51 = 2(18+m)
51/2 = 18 + m
25.5 - 18 = m
m = 7.5m
Answer: 2a - 14 = 2(a - 7)
Step-by-step explanation:
Because 2•a = 2a and 2•-7= -4 therefore, the answer is 2(a - 7).
Answer:
92 inches
Step-by-step explanation:
When a tire's size = P220/65 R 18, it means that:
- the rim is 18 inches wide (or 457 millimeters)
- the width of the tire is 8.7 inches (or 220 millimeters)
- the sidewall of the tire is 5.65 inches (or 144 millimeters)
- the 65 shows the relationship between tire width and sidewall (65%)
the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches
the circumference = 2 x π x radius or diameter x π = 29.3 x 3.141592 = 92 inches
