If a ball rotates 110 degrees in 8 seconds, how many degrees does it rotate in 32 seconds?

Vlad1618 [11]

Well 32 divided by 8 would be 4 so... 32 x 4 would be 128 so 128 times. If it’s not correct I’m really sorry.

A group of 12 people want to go to a concert. They can travel in a small car that takes one driver and one passenger and two car

trapecia [35]

Answer: There are 60 ways that they can travel to the concert.

Step-by-step explanation:

Since we have given that

Number of people want to go to a concert = 12

Number of cars = 3

Number of drivers in the group = 5

So, using the "Fundamental theorem of counting":

We get that

$5\times 4\times 3\\\\=60$

Hence, there are 60 ways that they can travel to the concert.

Find the sum to n terms of the series 0.6+0.66+0.666+.....................

RSB [31]

We have
 $0.6+0.66+0.666+0.6666$

Let's take 6 out from the series
$6(0.1+0.11+0.111+0.1111+....$

Now multiply and divide by 9
 $\frac{6}{9}(0.9+0.99+0.999+0.9999+....$

$\frac{6}{9}(1-0.1+1-0.01+1-0.001+1-0.0001+....
\\
\\\frac{6}{9}(1-10^{-1}+1-10^{-2}+1-10^{-3}+...$

all 1s add up to n
 $\frac{6}{9}(n-\frac{1}{10}\times \frac{1-(\frac{1}{10})^{n+1}}{1-\frac{1}{10}})$

PLZZZZZZZZZZZZZZZZ HELP ME!!! 1 1/8 to decimal show your work!!!

lions [1.4K]

Answer:

1.125

Step-by-step explanation:

1) First you have to turn it into an improper fraction

8*1 = 8. Add the numerator--> 8+1 = 9.

2) The improper fraction is 9/8

3) Divide 9 by 8

**Write this using long division

8 goes into 9 one time, so we will write one as our first digit

Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.

And this point we have 1.1 above

Carry down the 2 and the 0, 8 goes into 20 2 times so write 2

At this point we have 1.12

Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.

Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.
