Answer:
2 kilograms = 4.4 pounds (Approximately)
Step-by-step explanation:
Given:
1 kilogram = Approximately 2.2 pounds
Find:
number of pounds in 2 kilograms = ?
Computation:
We know that,
⇒ 1 kilogram = Approximately 2.2 pounds
So,
⇒ 2 kilograms = 2 × (Approximately pounds in 1 kilogram)
⇒ 2 kilograms = 2 × (Approximately 2.2 pounds)
⇒ 2 kilograms = 4.4 pounds (Approximately)
Answer:
20sets
Step-by-step explanation:
Since we are to select 3 unordered letters from the word q, u, a, k, e, s, we will apply the combination rule.
For example if r objects are to be selected from n pool of objects, this can be done in nCr number of ways.
nCr = n!/(n-r)!r!
Since the total number of letter in the word q, u, a, k, e, s is 6letters and we are to form 3 letters from it unordered, this can be done in 6C3 number of ways.
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
6C3 = 6×5×4×3×2×1/3×2×1×3×2×1
6C3 = 6×5×4/3×2
6C3 = 120/6
6C3 = 20
Hence 20sets of selection are possible
For the answer to the question above,
2r^2 + 3s^3 - r^2 + 4t^2 - r^2
r = -2
s = -3
t = 5
First, we should substitute everything into the expression
(2)((-2)^2) + (3)((-3)^3) - (-2^2) + (4)(5^2) - (-2^2)
Now we should simplify the exponents
(2)(4) + (3)(-27) - (4) + (4)(25) - (4)
Now we simplify the brackets
8 + (-81) - 4 + 100 - 4
so 8 minus 81 minus 4 plus 100 minus 4 is equal to +19
I hope this helps.
Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
4/9 × 3/2 = 12/18 = 2/3. •Your answer is 2/3, or two thirds.
