Answer:
122.5 units
Step-by-step explanation:
The perimeter of Figure B is the sum of its side lengths:
12 + 9 + 5 + 9 = 35
The perimeter of Figure A is that value multiplied by the scale factor:
(7/2)(35 units) = 122.5 units
Ok find circumference sinc that is what touches the grownd
C=pid
d=2.5
c=2.5pift
aprox pi=3.14 for problem
c=2.5(3.14)
c=7.85ft
how many 7.85ft does it take to get 5280 ft
7.85 times how many=5280
divide both sides by 7.85
how many=672.611
tenth
672.6
answer is 672.6revolutions

Answer:
option B
35
Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Formula to calculate combination
nCr = n! / r! * (n - r)!
We are given C(7,3)
here n = 7
r = 3
<h3>So plug values in the formula </h3>
7C3 = 7! / 3! * (7 - 3)!
= (7x6x5x4x3x2) / (3x2)(4x3x2)
= (7x6x5) / (3x2)
= 210 / 6
= 35
