For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
Answer:
The value of x is 56°
Step-by-step explanation:
Given that opposite angles in a cyclic quadrilateral is add up to 180°. So in order to find x, you have to write an expression in terms of x :
Next you have to solve it by substracting 124 to both sides :
A,C, and E are all correct answers
the volume of a sphere can be calculated with the formula v=4/3(pi)(r)^3
100% = 1.0
2.5% = 0.025
So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:
18 500 x 0.025 = $462.50
