Answer:
30.17 cm
Step-by-step explanation:
area of a circular disc=π*r^2
derivative of area=2*π*r
maximum error= derivative * error in radius
i.e . 2*π*r*0.2
(2/5) of (1/3) means to multiply.
(2/5)*(1/3)= 2/15
Answer:
7/12.
Step-by-step explanation:
There are 12 numbers totals.
The numbers 1, 7, 11, 8, 2, 4, and 10 are not in Set Q.
There are seven of those numbers which means that the probability of a number not being in Set Q is 7/12.
X + 5 + 11x = 12x + y
Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)
Subtract 12x from each side makes each zero.
5 = y
So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82
x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125
x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989
So we verified y = 5
