Answer:
144 feet to nearest foot.
Step-by-step explanation:
Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet
So we have 2 right angled triangles and:
tan 62 = h/x
tan 48 = h / (400- x) where h is the height of the balloon.
From the first equation x = h / tan 62 so plugging this into the second one:
tan 48 = h / ( 400 - h/tan 62)
h = 400 tan 48 - h tan 48 tan 62
h + h tan 48 tan 62 = 400 tan 48
h ( 1 + tan48 tan62) = 400 tan48
h = 400 tan 48 / (1 + tan 48 tan 62)
= 143.8 feet.
Answer:
800
Step-by-step explanation:
First do 20x20 (20 lines x 20 words per line) to get 400
Then multiply 400 by 2 (400 times both pages) to get 800 which is how many words Claire's report should be.
Well if there are 231 tickets, then divide 231 by three, that will equal 77, so if you see what i am doing,i am diving all tickets by 3 so that the students get 2/3 and the adults get the pther 1/3. so the answer is 77.
Yes you can you would have to combine 8n plus 8n which is 16n and then bring it down to 16n-4n to the second power
Divide 2,512 by 3.14 and round to the nearest whole number
