The probability is: 1/2 x 1/2 x 1/2 =1/8

30C5 =30! / (30-5)!. 5! =142,506

2108.0796948882174554

The answer is:

5.123687091_x10¹⁸

210 miles/10 gallons=21miles per gallon

294/21=14 gallons

3 1/2 batches = 7/2 batches

2 1/3 per batch = 7/3 per batch

(7/2)*(7/3)=49/6 => 8 1/6 cups of flour

All you need to do to turn this into function notation is replace V with f(x), or whatever is required. In this case, we should replace the s with an x.

f(x) = x^3

Here, f represents the function acting on x, the input.

As we know, V represents to volume, which means f(x) doesas well. s represented a cube side length, and we chose x to equal the same.

Both of these numbers are negative, so for the sake of ease, let's multiply both by -1 to make the equation 8 / 2/5.

First, let's make 8 into a fraction.

8/1 / 2/5

Now, use "keep, change, flip."

Keep 8/1...

Change the division sign into a multiplication sign...

8/1 * 2/5

And flip 2/5 into 5/2 (the reciprocal).

Now we have 8/1 * 5/2.

What we'll do is multiply the numerators together to find the solution's numerator and the denominators to find the solution's denominator.

8*5 = 40

1*2 = 2

We get 40/2. This can be simplified into 20/1, or just plain 20.

In conclusion,  -8 / -2/5 = 20.

We have a total of 10 sweets.

There are 5 green, so picking a green sweet out of all in the bag has a possibility of 5/10, or 1/2.

Now that Mary's taken out one sweet, there are 9 total left, and 4 green ones left. This makes the probability of picking a green sweet the second time 4/9.

If repeats are allowed then there are: 9^3 =729 ways.

If repeats are not allowed, then there are: 9P3 =9 x 8 x 7 =504 ways.

Not quite sure if you mean in general or on the calculator, but if you mean in general, all you have to do is take the decimal, put it over 1, and multiply by 10 until you get a whole number. Then, simplify.

Ex.

0.255

Put it it over 1...

0.255/1

Multiply by 10 until whole...

255/1000

Simplify...

51/100

15% = 0.15, so what we can do is multiply 15 by 0.15.

15(.15)=2.25

15% of 15 is 2.25.

It would be helpful if you rephrased your question...

If you mean:

7 * 1/3, then you could do the following:

Turn 7 into a fraction...

7/1 * 1/3

And then multiply the numerators together for the numerator of the solution and the denominators together for the denominator of the solution.

7*1 = 7

1*3 = 3

You would get 7/3, which simplifies to 2 1/3.

However, if you meant (7*1)/3, you would solve what's in the parenthesis....

(7)/3

And get 7/3, simplifying to 2 1/3.

Either way, the solutions are the same!

Solve for r:
12 = sqrt(r+160)

12 = sqrt(r+160) is equivalent to sqrt(r+160) = 12:
sqrt(r+160) = 12

Raise both sides to the power of two:
r+160 = 144

Subtract 160 from both sides:
Answer: |r = -16

.....  8.33%   of AN INCH.

39.99 + .14x <= 45

First, let's get x onto one side and subtract 39.99 from each.

.14x <= 5.01

Now, to isolate x, we'll divided each side by .14.

.14/.14 = 1

5.01/.14 ~ 35.79

This means...

x <= approximately 35.79.

4.5*10^3

between 10pm and 7:45am water level decreased by 13/16 how much did the water drop each hour

Number of hours between 10pm and 7:45am =9 3/4 hours

(13/16) / 9 3/4 =1/12, or about 8.33% drop in water level per hour.

There are 9 possibilities each time, and 3 digits are chosen total. 9 possibilities, 3 times.

9 x 9 x 9 = 729. There are 729 different possibilities.

9.75x=13/16

x=1/12 

1/12 each hour

4.5 x 10^3

HOWEVER if it is 4,500. (note the decimal) then it would be 4.500 x 10^3

Three angles of a triangle add to 180.The smallest angle is half the size of the largest angle. The third angle is 25 less than twice the smallest angle.Find the values of all three angles.

Let the largest angle =L

The smallest angle =1/2L

The third angle =2(1/2L) - 25

L + 1/2L + 2(1/2L) - 25 =180, solve for L

L=82 degrees - the largest angle.

82/2 =41 degrees - the smallest angle.

2 x 41 - 25 =57 degrees - the 3rd angle.

82 + 41 + 57 = 180 degrees.
