Circumference of a circle = 2π r (2 * π * radius) or πd (π * diameter)
Answer:a
Step-by-step explanation:
The expression that represents the amount that was not paid off is 
<u>Solution:</u>
Given, In 1995, the federal government paid off one-third of its debt. If the original amount of the debt was $ 4.920,000,000,000
We have to find which expression represents the amount that was not paid off
Now, we know that, amount that is not paid off = total debt – paid amount
Hence the expression and value of debt amount that is not paid off is found
Answer:
1 hour 6 minutes = 66 minutes.
Step-by-step explanation:
Starting the test at 2:34 pm,
Finishes the test 35 mins later, time = 2:34 pm + 35 mins = 3:09 pm
Then Kevin starts his practice at 4:15 pm
Time between time the test ended and when the practice started
= 4:15 pm - 3:09 pm = 1 hour 6 minutes = 66 minutes.
Hope this Helps!!!
Answer:
x=-11, -1, and 3
Step-by-step explanation:
x^3+9x^2-25x-33=0
There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11
