Answer:
30 centimeters
Step-by-step explanation:
You have to find the scaling of the lengths first, and to do that, you divide the 20 by 8, which would be 2.5. After, you multiply 2.5 by 12 to get your answer.
Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
Answer:
Irrational
Step-by-step explanation:
Answer: the width of the rectangle
= 31feet.
Step-by-step explanation:
Perimeter of a triangle = 2( l + b)
let the width = xfeet
The length = 2x feet.
Substitute for this in the equation above,
2( 2x + x ) = 186
2(3x) = 186
Divide by 2 through
3x = 93
Divide by 3
x = 31feet. Therefore, the width of the rectangular = 31feet.
Check.
Since the length is twice the width,
L = 31 x 2
= 62feet.
Put that into the formula above
2( 62 + 31 )
2 x 93
= 186 which is the perimeter of the rectangle.
