The solution for this question to determine how much of this alloy do you need in order to get 1 13/32 lb of tin.If the alloy is 85% copper, then it is 15% tin. So:
15n/100 = 45/32
4500 = 480n
n = 9.375 lbs. of the alloy to get 1.40625 lbs of tin.
You should mulitply. $23.78 * 0.20 = 4.756
Then you add. 4.756 to $23.78 = $28.536
Now you round $28.536 to the hundredths so that you can pay it with coins.
The anwser is $4.76 and the total amount for the taxi ride would be $28.54
Answer: Shop A
15% of 240 is 36 and 240-36 is 204 so shop B is more expensive.
Answer:
<h2><u><em>
x = 1</em></u></h2>
Step-by-step explanation:
If 10 less than 5 times a number is two more than 3 times the number, then the number is
10 - 5x = 2 + 3x
10 - 2 - 5x - 3x = 0
8 - 8x = 0
x = 1
---------------
check
10 - 5 * 1 = 2 + 3 * 1
5 = 5
the answer is good
Answer:
38
Step-by-step explanation:
For the case of a parallelogram, when the diagonals ( in our case AC & BD) are intersected, they are basically bisected ( divided into two equal halves ). Therefore when the diagonals intersect at point E, we can say that the diagonal AC is divided in two equal halves which in our case are AE and CE. since AE and CE are equal , we can say that,
