Dan's age is x.
Jack is three years older than Dan, so his age is x+3.
Harold is twice as old as Jack, so his age is 2(x+3).
Harold's age is five times Dan's age.
Jack is 5 years old.
By the pythagorean theorem, we know that (leg1)^2 + (leg2)^2 = hypotenuse^2. to see the proof refer to the following link: http://jwilson.coe.uga.edu/EMT668/EMT668.Student.Folders/HeadAngela/essay1/Pythagorean.html
plugging in what we know we have 16^2 + leg^2 = 20^2 and we find that leg = 12.
Answer:
proportionality.
Step-by-step explanation:
Constant of Porportianality.
Given BD and AC is a diameter of the circle:
We need to find the following:
1. measure of the arc BA
So,
the measure of the minor arc BA = 44
The measure of the major arc BA = 360 - 44 = 316
2. the measure of the arc ACB = 360 - 44 = 316
3. The arc BCD is a semicircle of the circle
So, the measure of the arc BCD = 180

The probability that Mae will roll an odd number
<u></u><u></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that Mae has a number cube with 6 sides that are numbered 1 through 6.</em>
<em>n(S) = { 1,2,3,4,5,6,} = 6</em>
<em>Let 'E ' be the event of odd numbers</em>
<em>Mae will roll an odd number</em>
<em>n(E) = {1, 3, 5} = 3</em>
<u>Step(ii):-</u>
<u>The probability that Mae will roll an odd number</u>
