Hello!
<h2>Answer:</h2>
Carla will pay $300.30 for the gold ring.
<h2>Explanation:</h2>
Sales tax is added on to the total cost of the item. We need to figure out how much tax is on the ring.
To do that, we must calculate 10% (or 0.10) of $273.00.
273 × 0.10 = 27.3
Now, add the tax to the cost of the ring.
273 + 27.3 = 300.3
Answer:
2,598,960
Step-by-step explanation:
It is a combination because order doesn't matter. You wouldn't want to call A-K-Q-J-10 of hearts a different combination than 10-J-Q-K-A.
52 C 5 = 2,598,960
This will only have one solution because it does not deal with a quadratic. Then to isolate x you need to get the similar terms on different sides by subtracting or adding, Then divide both sides by the number next to x (coefficient).
Answer:
4√2i , -4√2i.
Step-by-step explanation:
3x^2 + 64 = 2x^2/2
3x^2 + 64 = x^2
2x^2 + 64 = 0
2x^2 = -64
x^2 = -32
x = +/- √-32
x = +/- √16* -2
x = +/- 4√2 i.
