Answer:
B
Step-by-step explanation:
First find the circumference of the circle with radius of 9 inches:
The full angle has 360°, so, to find the length of the arc DE, you can write:
which yields a proportion:
Denominator is the number which appears at the
bottom of fraction so the fraction we want is in the form X/8 and also less
than 5/6
Lets start from changing the values of X from
1.
1/8 = 0.125 and 5/6 = 0.8333
2/8 = 0.25
3/8 = 0.375
4/8 = 0.5
5/8 = 0.625
6/8 = 0.75
7/8 = 0.875, this is greater than 5/6
<span>So, the fractions with denominator 8 and less
than 5/6 are 1/8, 2/8, 3/8, 4/8, 5/8 and 6/8</span>
Answer:
a]2.3 hrs
b]3.6hrs
Step-by-step explanation:
4hrs = 12 miles
x = 7miles
4 x 7=28/12=2.3
4 x 11=44/12=3.6hrs
Answer:
true
Step-by-step explanation:
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
