Answer: (1) x²y (2) 7pqr (3) a (4) 6a² (5) y³z²
Step-by-step explanation:
(1) x^4y³ and x²y
x^4y³ = x²y(x²y²)
x²y = x²y
Therefore the Highest Common factor
x²y which is the common factor.
(2) 14p²qr^4 = 2 x 7 x p² x q x r^4
49p²q²r = 7 x 7 x p² x q² x r
35pqr = 5 x 7 x p x q x r
Therefore HCF = 7 x p x q x r
= 7pqr
(3) -a^5 = -( a x a x a x a x a )
= -(a^5)
ab³ = a x b x b x b
Therefore HCF = a
(4) 6a² = 2 x 3 x a x a
-18a6 = -( 2 x3 x 3 x a x a x a x a x a x a)
-12a² = -( 2 x 2 x 3 x a x a )
Therefore HCF = 2 x 3 x a²
= 6a²
(5) 3y³z² = 3 x y x y x y x z x z , 3 x y³ x z²
15y^4z² = 3 x 5 x y x y x y x y x y x z x z, 3 x 5 x y^4 x z²
y^6z³ = y^6 x z³
Therfore HCF = y³ x z²
= y³z²
Answer:
1) 90%
2)40%
3)75%
Step-by-step explanation:
the space between 2 lines are considered 10%. so let's take the first one for instance
1) as I said before, the space between 2 lines are considered 10%. So what you are going to use is the 10 times table (it will be a really helpful thing if you know all of the time table from 1 - 10) now what you do is count all the way from 0 till the blue thing ends. but If blue thing ends in the middle like in the picture number 3 then it's considered 5% since it's only halfway
I hope it was hopeful and that you understood
All you got to do first is:
Change the 9% to decimal, which is .9
and then multiply all numbers
$2860 x .9 x3 is $7,722
Hope this helps! (Hope im right)
Answer:
log x²
Step-by-step explanation:
Using the rules of logarithms
log x + log y ⇔ log xy
log
⇔ n log x
Given
2logx + 4logy
= logx² + log
= log x²
It’s a composite because it has a multiple other than itself
