Answer:
D) 1,814, 400
Step-by-step explanation:
It is permutation.
nPr = n!/(n -r)!
Now we have to use the above formula and simplify.
12P10 = 12! / (12 - 10)!
= 12!/2!
=479001600/2
12P10 = 239,500,800
Now let's find 12P2
12P2 = 12!/(12 -2)!
= 12!/10!
= 479001600 / 3628800
12P2= 132
Now we have to divide 12P10 by 12P2
= 239500800/132
= 1,814,400
This will helpful.
Thank you.

Answer:
1) Option C
2) Option C
3) Option B
4) Option B
5) Option A
Step-by-step explanation:
1) Identify the like terms ?
Terms are 9x, 10y, –9y, 10.
Like terms are those having same variable.
i.e. 10 y and -9y are like terms.
So, Option C is correct.
2) The term 25ab and which other term are like terms?
Option terms are 25,24a,5ba,10b
Like terms are those having same variable form.
i.e. 25ab and 5ba are like terms.
So, Option C is correct.
3) Combine like terms.
Expression
combine like terms means adding and subtracting like terms with same variable.
i.e.
So, Option B is correct.
4) Combine like terms.
Expression
combine like terms means adding and subtracting like terms with same variable.
i.e.
So, Option B is correct.
5) Combine like terms.
Expression
combine like terms means adding and subtracting like terms with same variable.
i.e.
So, Option A is correct.
Answer:
Height = 3 inches and Base length = 7 inches
Step-by-step explanation:
1. Information provided to answer the question correctly:
Base of the triangle = x+ 4
Height of the triangle = x
Area of the triangle = 10.5 inches²
2. Find the base length and height
Let's recall the formula of the area of a triangle:
Area = (Base * Height)/2
Replacing with the values we know:
10.5 = x (x + 4)/2
21 = x²+ 4x
x²+ 4x - 21 = 0
(x + 7) (x - 3) = 0
(x₁ + 7) = 0 ⇒ x₁ = -7
(x₂ - 3) = 0 ⇒ x₂ = 3
We take x₂ as the answer because x₁ = -7 is not a valid height.
Height = 3 inches and Base length = 7 inches
2.5-4 = 2
Answer: False
Step-by-step explanation:
Answer:
225
Step-by-step explanation:
9*10 = 9 times 10 = 90
2kg = 90
that means 1kg = half of 90 = 45
1kg = 45
5 kg = 45 times 5 = 225
By the way at the end of your question you put "2)1.2kg of sugar" but I don't know what that is so i ignored it
