Answer:
237.65 feet
Step-by-step explanation:
From the diagram attached,
Let the height of the blimp above the ground be h
From triangle A of the diagram,
tan18° = (360-y)/h
h = (360-y)/tan18°..................... Equation 1
Also
From triangle B in the diagram,
tan50° = y/h
h = y/tan50°.............................. Equation 2
Equation equation 1 and equation 2
(360-y)/tan18° = y/tan50°
tan50°(360-y) = tan18°(y)
1.19(360-y) = 0.325(y)
428.4-1.19y = 0.325y
428.4 = 0.325y+1.19y
1.515y = 428.4
y = 428.4/1.515
y = 282.8
Substituting the value of y into equation 2
h = 282.8/tan50°
h = 282.8/1.19
h = 237.65 feet.
Answer:
P(white ball)=0.29
Step-by-step explanation:
12 yellow balls
5 red balls
7 white balls
12+5+7=24
so 24 balls in the bag
=0.2916
rounded to the nearest is 0.29
The first thing you want to do is factor out 13. It can ether be (1, 12), (2, 11), (3, 10), (4, 9), (5, 8), or (6, 7). In this case, it says the difference of the two numbers is 3, so you subtract the two numbers 8 and 5 to get three. Your answer is 8 and 5
