Step-by-step explanation:
secants originating from the same point have the same relative length relationship :
outside part × sum of outside and inside parts
is the same for every secant from the same point.
so,
5×(7+5) = 6×(2x-8+6) = 12x - 12
60 = 12x - 12
12x = 72
x = 6
WV = 2x - 8 = 2×6 - 8 = 12 - 8 = 4
so, B is correct.
Answer:
The number of variables in the set is 5
Step-by-step explanation:
we us to able to understand how we arrived at 5 as the number of variables that is available in the set of data above we have to define and understand the keyword variable.
A variable; is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item.
hence by the definition of a variable we know that hometown is a variable=1,GPA is a variable=2, number of classes is a variable=3, number of siblings is a variable=4, and favorite subject is also a variable=5.
hence we conclude that the number of variables=5
Answer:
3.14 km
Step-by-step explanation:

if here radius is 1 kilometres, π is 3.14
then, circle's area = 3.14 * 1 * 1 = 3.14 km
