I think the answer is A <br><br><br> Correct?
xeze [42]

You can see that there are 6 rock CDs, over a total of

6+10+4+8+12 = 40

So, the ratio of rock CDs over the total number of CDs is

\dfrac{6}{40} = 0.15

Which is 15%.

So, yes, the answer is A

What is the solution? x=? 2x+3=4x+2
Pie

2x+3=4x+2

-2 both sides

2x+1=4x

-2x both sides

1=2x

2x=1

÷2 both sides

x=0.5 or 1/2

If mark got 6 questions out of 40 incorrect what percent of the questions did he get correct?
kap26 [50]
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.

What is the common ratio for the geometric sequence? 18,12,8,163,… Enter your answer in the box.
uysha [10]

Answer:

\frac{2}{3}.

Step-by-step explanation:  

We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.

We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.

\text{Common ratio of geometric sequence}=\frac{a_2}{a_1}

Let us use two consecutive numbers of our sequence in above formula.

a_2 will be 12 and a_1 will be 18 for our given sequence.

\text{Common ratio of geometric sequence}=\frac{12}{18}

Dividing our numerator and denominator by 6 we will get,

\text{Common ratio of geometric sequence}=\frac{2}{3}

Let us use numbers 8 and 16/3 in above formula.

\text{Common ratio of geometric sequence}=\frac{\frac{16}{3}}{8}

\text{Common ratio of geometric sequence}=\frac{16}{3*8}

\text{Common ratio of geometric sequence}=\frac{2}{3}

Therefore, we get \frac{2}{3} as common ratio of our given geometric sequence.
