8 yards is equal to 288 inches.
1 yard=36 inches
36x8=288
288 converted to yards=8
The ratio would be 6/54
Which reduced would make 1/9
So 1 cm is 9 miles
Answer:
67.38 degrees
Step-by-step explanation:
this is a right triangle so we can use sohcahtoa
we want to calculate angle A
we know the side opposite to A as well as the hypotenuse. 13 is the hypotenuse because it is opposite the right angle
thus, sin(A) = opposite/hypotenuse = 12/13
arcsin(12/13) = A ≈ 67.38 degrees
The percent increase in the price index from 1960 to 1970
is:
% increase in price index = (38.8 – 29.6) * 100% / 29.6
% increase in price index = 31.08%
Therefore the price of a dozen tangerines in 1970 (X) is:
31.08 = (X - $0.31) * 100 / $0.31
X =
$0.41
