Answer:
20(pi)
Step-by-step explanation:
• equation for the circumference of a circle= 2(pi)r
• You are given the diameter ( 20ft) but you need the radius (r) for the equation.
• divide 20 by 2 to get the radius since it is half of the diameter.
• 20/2=10 so c= 2(pi)(10)
• 2(10)=20
• plug in pi and your final answer is 20(pi)
If it's likely to happen, but it's not a certainty, then it has a high chance of happening. Pick P(D).
A "solution" would be a set of three numbers ... for Q, a, and c ... that
would make the equation a true statement.
If you only have one equation, then there are an infinite number of triplets
that could do it. For example, with the single equation in this question,
(Q, a, c) could be (13, 1, 2) and they could also be (16, 2, 1).
There are infinite possibilities with one equation.
In order to have a unique solution ... three definite numbers for Q, a, and c ...
you would need three equations.
Answer:
- 15t + 5c = b
- $275
Step-by-step explanation:
Let "t' be the number of t-shirts bought.
Let "c" be the number of CDs bought.
Let b" be the total cost.
15t + 5c = b
We buy 10 t-shirts so t = 10.
We buy 25 CDs so c = 25.
We are trying to find b.
15t + 5c = b
15(10) + 5(25) = b
150 + 125 = b
275 = b
Best of Luck!
