Answer:

0.3

Step-by-step explanation:

Divide the second term (12) with the first term (40), and you'll get 0.3

This is correct because you get the terms in the correct order when multiplying:
(First term: 40. Common ratio: 0.3)
40 x 0.3 = 12
12 x 0.3 = 3.6

40, 12, 3.6

svp [43]

Answer:

Option A - 10

Step-by-step explanation:

Given : There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB.

To find : How many color patterns are possible?

Solution :

Total number of chips = 5

So, 5 chips can be arranged in 5! ways.

There are 3 red chips and 2 blue chips.

So, choosing 3 red chips in 3! ways

and choosing 2 blue chips in 2! ways.

As changing the places of similar chip will not create new pattern.

The total pattern is given by,

$T=\frac{5!}{3!\times 2!}$

$T=\frac{5\times 4\times 3!}{3!\times 2}$

$T=10$

Therefore, color patterns are possible are 10.

Option A is correct.

Which of the following are solutions to the equation below?

WARRIOR [948]

$\\ \rm\bull\rightarrowtail x^2-3x+27=6x+7$

$\\ \rm\bull\rightarrowtail x^2-3x-6x+27-7=0$

$\\ \rm\bull\rightarrowtail x^2-9x+20=0$

$\\ \rm\bull\rightarrowtail x^2-5x-4x+20=0$

$\\ \rm\bull\rightarrowtail x(x-5)-4(x-5)=0$

$\\ \rm\bull\rightarrowtail (x-4)(x-5)=0$

$\\ \rm\bull\rightarrowtail x=4,5$
