Because it does not specify the order and in division, the order matters.
They will tip $8.10.
How to Do it/ Work:
18 * 0.45 = 8.1
Square root of a number is 2 numbers that multiply to get 4 that are the same
first find the factors
4=2 times 2
then find the doubles and write only one from each pair
√4=2
so if you had a number like 36 then
36=2 times 2 times 3 times 3
the doubles are 2 and 3 so
√36=2 times 3=6
square root of 4 can be 2 or -2
Answer:
5.25 is the lenght of the arc AB.
Step-by-step explanation:
First, since we are told the answer should be expressed in radians, we need to convert the arc angle into radians, we do that by multiplying the angle by π and dividing by 180.
60° * π/180 = 1.05rad
Now, there is a simple formula to calculate the arc lenght, A = Ф*r, where:
A = arc lenght
Ф = arc angle (60°=1.05rad)
r = radius (5cm)
A = 1.05*5cm
A = 5.25cm
