Roberta is lining up nine different coloured blocks. There are five green blocks, two white blocks and two orange blocks. In how
Amanda [17]
If the blocks were 9 different colors, then there would be

     9 !(factorial) = 362,880 different ways to line them up.

But for each different line-up, there are 5! =120 ways to arrange
the green blocks and you can't tell these apart, 2!= 2 ways to arrange
the white blocks and you can't tell these apart, and 2!=2 ways to arrange
the orange blocks and you can't tell these apart.

So the number of distinct, recognizable ways to arrange all 9 blocks
is

         (9!) / (5! · 2! · 2!)  =  (362,880) / (120 · 2 · 2)  =  756 ways.

GaryK [48]

Answer:

First term of the sequence is 11

Step-by-step explanation:

Let a be the first term and d be the common difference

We have

The sum of the second term and the ninth term of an arithmetic sequence is -5

a+(2-1)d+a+(9-1)d=-5\\\\2a+9d=-5---eqn1

The sum of the third and fourth terms of the same sequence is 7

a+(3-1)d+a+(4-1)d=7\\\\2a+5d=7---eqn2

eqn 1 - eq2

4d=-12\\\\d=-3

Substituting in eqn 1

2a+9\times -3=-5\\\\2a=22\\\\a=11

First term of the sequence is 11

How many servings (including fractions of a serving) are there in five and a third
Xelga [282]

Answer:

10 \frac{1}{6} servings

Step-by-step explanation:

there are 2 half cups in a cup

2x =1

the x in this case will be the 5 cups

so

2 (5) = ? cups

10 cups

now onto the \frac{1}{3} cup

\frac{1}{2} * \frac{1}{3} = \frac{1}{6}

and you add that onto the 10 cups
