Answer:
60.0 L
Step-by-step explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is gas constant,
and T is absolute temperature.
Since n and R don't change:
P₁V₁ / T₁ = P₂V₂ / T₂
(1.08 atm) (50.0 L) / (25 + 273.15 K) = (0.855 atm) V / (10 + 273.15 K)
V = 60.0 L
Answer:
Step-by-step explanation:
You want to begin by making each fraction have the same common denominator. The LCF (least common factor) is 77. So, knowing this, we can now multiply the fractions that need to have a denominator of 77.
1. 5/7*11/11=55/77
2. 9/11 * 7/7 =63/77
Now we can add
55/77 + 63/77 + 21/77 = 139/77 or 1.805194805
Answer:
its a, b, d, e
Step-by-step explanation:
3{[9(x - 2) + 7] - 2[4(x + 5) - 36]}
= 3[9x - 18 + 7 - 2(4x + 20 - 36)]
= 3(9x - 11 - 8x - 40 + 72)
= 3(x + 21)
= 3x + 63
The length and width of the rectangle are (10x + 7) and (x – 2). Then the correct option is C.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Mandisa draws a rectangle to represent the area of her yard. The area can be represented by 10x² – 13x – 14.
We know the formula of area
Area = length × width
On factorizing, we have
Area = 10x² – 13x – 14
Area = 10x² – 20x + 7x – 14
Area = 10x(x – 2) + 7(x – 2)
Area = (10x + 7)(x – 2)
Thus, the length and width of the rectangle are (10x + 7) and (x – 2). Then the correct option is C.
