28mi/1 hr = 28 mi/60 min = 1 mi/(60/28) min =
28 mi/hr = 28 mi/60 min since there are 60 min in 1 hr
1 mi/(60/28) min since you divide top and bottom of 28/60 by 28 to get
1 mi/(60/28) min = 1mi/(15/7) min = 1 mi/ 2 1/7 min
Answer:
the answer of given question is $400.
Answer: 4 1/2 - 1 11/12 = 2 1/3 but in decimal form 2.3
As the angle sum of triangle is 180
with one angle is 60 the sum of the remains two angles is 120
let the smallest angle be x
as the larger angle is twice of the smaller angle, it will be 2x
therefore, x+2x = 120, x= 40
so the smallest angel of the triangle is 40 degree
