Answer:
12,500 people went to the fair.
Step-by-step explanation:
Set up an equation:
Variable x = number of people who went to the fair
12/100 = 1500/x
Cross multiply:
12 × x = 100 × 1500
12x = 150000
x = 12500
Check your work:
12500 × 12%
Convert percentage into a decimal:
12500 × 0.12
1500
1500 people received water bottles so this is correct!
Answer:
Steps To Convert From Base 10 to Base 2-
Divide the given number (in base 10) with 2 until the result finally left is less than 2.
Traverse the remainders from bottom to top to get the required number in base 2.
Hope this helps you get the answers!
I got 314 too, you have to use your formula a=pi(r2)
In average, when x increases by 1, f(x) also increases by the same value of 1 between x=2 and x=6 :)
Answer:
Area of a regular decagon with a perimeter of 60 ft. = 277 squared ft
Step-by-step explanation:
Decagon has 10 sides So 60/10 = 6 (each side = 6ft )
The sum of the interior angles of a decagon is 1 440 degrees.
There are 10 equal isosceles triangles of base angles 72 degrees in a decagon
Each isosceles triangle can subdivided into 2 right-angled triangles with height h and base length = (6/2) = 3 cm and base angle 72 degrees.
Height of right-angled triangle h = 3 tan 72 ft.
Area of 1 right-angled triangle = (1/2)(3)(3 tan 72) = 13.85 squared ft
Area of decagon = 20 right-angled triangles = 277 squared ft
