What you need to do is the following:
Calculate the total number of identical twins which will be 2+2 = 4. and then total of twins is 12. The probability for her to have identical twins will be known with the following formula:
Identical twins = 4 / 12
that is 0.3333
The probability is 0.3333

Identify the lengths of QS and SR
Semenov [28]
<span>The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides  </span>⇒
<span>
10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2

QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8 
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6

Answer is QS=8, SR=9.6

Answer:

a)45min

b)900min

Step-by-step explanation:

We were told that it takes Matt 3 minutes to read one page in a book.

It implies that 3minutes = 1page of the book

Then he continues to read at the same pace, he can read 15 similar pages in minutes.

a)Then, he can read 15 similar pages in

15x3 minutes.which is 45minutes.

b)Then if the book has 300 pages, it will take him. 300×3 minutes to read it.which is 900mins

A supermarket finds that the number of boxes of a new cereal sold increases each week. In the first week, only 26 boxes of the c
sveta [45]

Answer:

aₙ = 31n -  5

Step-by-step explanation:

The terms of your sequence are.

26, 57, 88, …

This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,  

aₙ = 26 + 31(n - 1) = 26 + 31n - 31

aₙ = 31n - 5

The explicit rule for the arithmetic sequence is aₙ = 31n - 5.
