so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know
(1125)(0.9) = 0.75y
(1125)(0.9) = 0.75y <--- solve for "y", that's how much the final amount of milliliters will be
how much pure water was added? subtract 1125 from that, or y - 1125
Answer:
.<em><u>O</u></em><em><u>P</u></em><em><u>T</u></em><em><u>I</u></em><em><u>O</u></em><em><u>N</u></em><em><u> </u></em><em><u>A</u></em><em><u>:</u></em><em><u>2</u></em><em><u>0</u></em><em><u>°</u></em>
SINCE THE BOTH SIDE OF LINE IS PERPENDICULAR
THEREFORE,90°
THEREFORE,
4X-10+X=90.
5X-10=90
5X=100
X=20°
Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
23/45
Answer: 23/45
Answer:
9.06
Step-by-step explanation:
Length of the line between two points;
Length = square root of [(4 - 3)^2 + (-2-7)^2]
Length = square root of [ 1 + 81 ]
Length of AB = square root of 82
Length AB = 9.06
