Multiply the 6 (the denominator), and the 13 (the whole number). To this product, add the 5 (the numerator).
<span>It then gives you 83, which is now the numerator for the improper fraction, and use the 6 as the denominator for the improper fraction.
Therefore the mixed number (13 6/5) is now 83/6 written as an improper fraction.</span>
Answer: 1/3 = 33.3% or 33 ⅓%
1/9 = 11.1%
2/9 = 22.2%
8/9 = 88.9%
Step-by-step explanation:
Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.
All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.
Answer:
y = -x - 2
Step-by-step explanation:
Simplifying the equation of our line;
y - 1 = (x + 2)
y = x + 3
The slope of our line is 1
The slope of the perpendicular line(s) must be -1 (the product of slopes of two perpendicular lines = -1)
The line whose slope is -1 (from the choices) is the one whose equation is:
y = -x - 2
Let x be volume of 5% acid and y be volume of the 8%
x + y = 750 and
0.05x + 0.08y = 0.07*750 = 52.5
from first equation y = 750 - x so substituting in the second equation:-
0.05x + 0.08(750 - x) = 52.5
0.05 - 0.08x = 52.5 - 60
-0.03x = -7.5
x = -7.5 / -0.3 = 250 mls <------ answer
Use the Pythagorean Theorem, substituting 8, 15, and 17 for a, b, and c respectively. Then, simplify to determine whether the equation is true.
As any number is clearly equal to itself, this statement is true, so 8, 15, and 17 is a valid Pythagorean Triple.
