Answer: Option 'c' is correct.

Step-by-step explanation:

Let the number of children be 'c'.

According to question,

"There are 9 more children than parents in a room.

Let the number of parents would be 'p'.

According to question, it becomes,

c-p=9\\\\c-9=p

As there are total 25 people in the room = 25

So, it becomes,

c+p=25\\\\c+c-9=25\\\\2c-9=25\\\\2c=34\\\\c=17

Hence, there are 17 children and 17-9 = 8 parents.

Therefore, option 'c' is correct.

Sever21 [200]

To find the height of the cactus, make a ratio.

58 inches divided by 4 feet equals x inches divided by 8 feet.

58/4 = x/8

14.5 = x/8

116 = x

The height of the cactus is 116 inches.

Explain and demonstrate how to turn 4/20 into a percent
iren2701 [21]

Answer:

20%

Step-by-step explanation:

We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.

Another way is

20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%

CAN SOME ONE PLS HELP ME THIS IS REALLY HARD
Dmitry_Shevchenko [17]

Answer: 1.25 times as far

Step-by-step explanation:

This problem requires you to find something called the unit rate.

Getting the unit rate for Car A is very simple, and can be found to be 25mi/gal.

To find the unit rate for Car B, simply look at the second row.  Because the car can go 60 miles on 3 gallons of gas, divide both these numbers by 3 to get 20mi/gal.

Then, simply multiply both of these numbers by 11 to get 25 * 11 = 275, and 20 * 11 = 220.

Then, by doing 275/220, you get your answer: 1.25.

Hope it helps :) and let me know if you want me to elaborate.

Find the sum of the infinite series 1/3+4/9+16/27+64/81+.... if it exists.
pshichka [43]
9/27, 12/27, 16/27

So this is a geometric sequence as each term is 4/3 the previous term.

Since the common ration is greater than one the sum of the series diverges, it does not exist.  (The sum just keeps getting larger and larger)

For a geometric series to have a sum r^2<1

So that the normal sum....

s(n)=a(1-r^n)/(1-r)   becomes if r^2<1

s=a/(1-r)
