The easiest way to solve this is to take the amount of each coin and multiply it by its value. Afterwards add each total together to determine the amount of money that Ann has.
145 pennies X $0.01 = $1.45
42 dimes X $0.10 = $4.20
12 quarters X $0.25 = $3.00
$1.45 + $4.20 + $3.00 = $8.65
Therefore Ann has $8.65
To solve this, take a look at the images provided and first find out the number of polygons out of the total number of cards given which would be 3 polygons out of 5 cards, which would be better represented as the fraction 3/5. Now, the question asks to find the probability of Julie picking a card that shows a polygon, and since 3 out of 5 of the cards are polygons, your answer would be 3/5.
We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.
There are about 2 pounds in one kilogram.
Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.
2 * 2 = 4
So, the answer to this question is 4 pounds.
The answer for 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
What is the mathematical expansion?
A mathematical expansion can be described as the finite combination of symbols which can be seen as one having rules which is usually based on the context that is been used.
The solution for the question is 2a^10bx + 2a^4by-6ab
Therefore, the expansion of 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
