Answer:
24.5
Step-by-step explanation:
the radius is half of a diameter
so the radius is 3.9
24.5 = 2πr= 2 * π * 3.9 ≈ 24.504
D) a reflection in the line y = x
She got back $6.50.
explanation -
30 x 1.45 = 43.5
50 - 43.5 = 6.50
Answer: 8
Step-by-step explanation:
Pythagorean theorem - a^2+b^2=c^2
a^2+15^2=17^2
a^2+225=289
(subtract 225 from both sides)
a^2=64
(sq root both sides)
a=8
Answer:
The probability that someone buys either an arctic cat or a ski doo=
Step-by-step explanation:
A person is shopping for a new snowmobile.
The probability that someone buys an arctic cat is =P(A)=
,
The probability that someone buys a polaris=P(B)=
and
The probability that someone buys a ski doo=P(C)=
.
Now, The probability that someone buys either an arctic cat or a ski doo=P(AorC)=P(A)+P(C)
=
=
Which is the required probability.
