Given that the angle is 25 degrees, we shall apply cosine rule to solve this question.
c^2=a^2+b^2-2abcosC
thus plugging the values we get:
15^2=x^2+20x^2-40xcos25
x^2-36.252x+175=0
thus solving the quadratic using quadratic formula we obtain:
x=[36.252+/-√614.208]/2
x=5.7 km or 30.5 km

Answer:
a. 4/7
e. 3/4
Step-by-step explanation:
For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.
__
a. The desired fraction is ...
(dots in the triangle)/(all dots) = 16/28 = 4/7
__
e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4
Answer:
Step-by-step explanation:
You can create a ratio from the provided recipe,
for every 6 cups of brown sugar you need 9 cups of white sugar so it would be 6:9
?:24
24/9=2.6
6x2.6=15.6
so for 24 cups of white sugar you would need about 16 cups of brown sugar.
