Answer:
(1.3×10000)×0.05=650$
Step-by-step explanation:
It was sold for 30% more than at the auction, which means we add 30% which is 0.3 of the price at the auction so 10000 + (30/100)×10000 which equals 13000. Now take 5% which is 0.05 of 13000 to get the final answer
(x% is equal to X/100)
Answer:
Steve has a total of $140.
Step-by-step explanation:
At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.
140.50 - 50 = $90.50
So now, Steve has only $90.50 left.
Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.
90.50 - 31.25 = $59.25
Now, Steve has $59.25 left.
Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.
59.25 + 80.75 = $140
Therefore, Steve now has a total of $140.

Answer:
We need to find the zeros.
4x^4 + 8x^3 - 7x^2 -21x - 9
You're supposed to use synthetic division, assuming you're in algebra 2. I removed my calculus work.
x = -1 1/2, 1+sqrt5/2 , 1-sqrt5/2
x= -1.5000000119775176
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
x= -0.618033988749895
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
x= <u>1.618033988749895</u>
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
