The answer is 4.
36/63 = 0.57
4/7 = 0.57
Lots of red herrings in this question! The beacon is circular, so you need to find the area of a circle with a diameter of 36 inches.
Area of a circle = pi x radius^2
remember radius is half the diameter!
We are given a scale that for every 1 in on the plan, the actual length will 6.5 ft.
The maximum distance across the pond on the plan is 9.75 in. So that means we will need to take 6.5 ft 9.75 times. So our answer is
6.5*9.75=63.375 ft. That's the answer.
We can visualize this a different way
1 in = 6.5 ft
9.75 in = x ft
And from here it's a little more clear to see what needs to be done.
Hope this helped!
Answer:
D
Step-by-step explanation:
I had a test and this is the answer. :)
There are none that work, the only close two are 3 and 24 + 2 and 25, but they multiply to 72 and 50, but if you can use decimals, you could use 2.445+24.555
