[tex] \dfrac{49 - \frac{1}{r^2} }{7 - \frac{1}{r} } [/tex]

Rewrite the fraction as division:

Make them into single fraction:
[tex]= \dfrac{49r^2 - 1}{r^2} \div \dfrac{7r - 1}{r} [/tex]

Cancel the common factors:

Comment. The best way to do this is to let 1/r = a and 1/r^2 = a^2. Now rewrite the problem.

Solution
[tex] \frac{49 - a^2}{7 - a} \\ \frac{(7 - a)(7 + a)}{7 - a}\text{ Notice a cancellation can take place} [/tex]

There is a 7 - a in both numerator and denominator, so that cancel providing a does not equal 7. a cannot equal 7 because that will put a 7 in the denominator and that makes the whole fraction = something over 0 which is undefined.

Answer
So far what we have is
7 + a

But a = 1/r
So the answer can be 7 + 1/r

r can be anything but 0 [for this answer]

Greg has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Greg's Jumble has 666 classical songs, 777 rock songs, and 999 rap songs on it. What is \text{P(not a rap song})P(not a rap song)P, left parenthesis, n, o, t, space, a, space, r, a, p, space, s, o, n, g, right parenthesis?

Answers

We have been given that Greg's Jumble has 666 classical songs, 777 rock songs, and 999 rap songs.

Therefore, total number of songs are

[tex]666+777+999\\ =2442[/tex]

The formula for probability is given by

[tex]P(E)=\frac{n(E)}{n(s)}[/tex]

Let us first find the probability for rap song

[tex]P(\text{rap song})= \frac{999}{2442} \\ P(\text{rap song})= \frac{9}{22}[/tex]\\

Therefore, we have

[tex]P(\text{ not rap song})=1- P(\text{rap song})\\ \\ P(\text{ not rap song})=1-\frac{9}{22} \\ \\ P(\text{ not rap song})=\frac{13}{22} =0.59[/tex]

Hence, we have

P(not rap song)=0.59

Angela owns a set of 6-inch tall glasses. Each glass has a diameter of 3 inches. Angela has three people over for dinner. Each guest will be served a full glass of milk. How much milk will Angela need ?

Answers

Dimensions of the glasses: Diameter, d = 3 in; depth, h = 6 in

Volume of 1 glass = (πd^2/4)*h = (π*3^2/4)*6 = 42.41 in^3

Each of the three guests will be served a glass full of milk.

Volume of milk required = 3*volume of 1 glass = 3*42.41 = 127.23 in^3
But,
1 in^3 = 0.0163871 liters

Therefore,
127.23 in^3 = 127.23*0.0163871 ≈ 2.09 liters will be required.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data provided in the question,

The given number is 7,777.777

Now, we have to compare the number 7 which is at the hundreds place with the 7 in the place left to it.

So, the 7 which is left to the 7 at the hundredth place will be 10 times it. Also, the 7 which is the second left to the 7 at the hundredth place is 100 times and so on it will increase like this.

a 25 gram sample substance that's used for drug research has a k-value of 0.1229. find the substances half-life, in days using the exponential decay formula. round your answer to the nearest tenth

Answers

With a k-value of 0.1229, the half-life is approximately 5.6 days.

The exponential decay formula is given by:

amount remaining = initial amount × e^-(k × t)

For a substance's half-life, the amount remaining is half of the initial amount. The formula to find the half-life (t1/2) is:

t1/2 = ln(2) / k

Here, ln(2) is approximately 0.693 and k is given as 0.1229. Substituting these values in:

t1/2 = 0.693 / 0.1229 ≈ 5.64 days

Rounding to the nearest tenth, the half-life of the substance is 5.6 days.

Polygon ABCDEF is the result of a translation of polygon GHIJKL . GL¯¯¯¯¯ is parallel to HI¯¯¯¯¯ in the pre-image. please help

Answers

Since GL and HI are parallel to each other, then in the translation this condition is going to be kept. So that, we can write in these gaps that AB and FE are parallel to each other.

GL parallel to HI in the pre-image ensures AB remains parallel to FE in the translation.

Given that GL and HI are parallel, we can infer that AB and FE will also remain parallel in the translation. The parallelism of lines GL and HI suggests that their corresponding sides, AB and FE, will exhibit the same parallel relationship during the translation process. This is a consequence of the consistent geometric transformation applied to all points on lines GL and HI. As each point on GL undergoes translation, its corresponding point on HI experiences the same displacement, preserving the parallelism.

Therefore, we can confidently state that AB and FE maintain their parallel orientation, aligning with the geometric properties of the translation that preserves parallel lines. The parallelism observed in the original configuration persists throughout the translation, ensuring that AB and FE remain parallel to each other.

What is the probability that at least 2 students in a class of 36 have the same birthday?

Answers

Given a group of n students, and given the fact that there are 365 days in one year, the probability that there are no students with the same birthday is given by
[tex]p_{no} (n) = \frac{364}{365} \cdot \frac{363}{365} \cdot ... \cdot \frac{365-n+1}{365} = \frac{364!}{365^{n-1} (365-n)!} [/tex]
Therefore, the probabilty that there are at least 2 students with same birthday is the complementary of this value:
[tex]p_{yes} (n) = 1 -p_{no}(n) =1- \frac{364!}{365^{n-1} (365-n)!}[/tex]

And if we use n=36 (number of students), we find
[tex]p=1- \frac{364!}{365^{36-1} (365-36)!} \sim 0.83[/tex]
So, the probability that there are at least 2 students in a group of 36 with same birthday is approximately 83%.

fresh raspberry contain 80% water.Dried raspberry contain only 20%.how many pounds do you get from 36lb fresh berries

Answers

80% water = 36 lbs fresh berries

1 % water = 36 ÷ 80 = 0.45 lb

20% water = 0.45 x 20 = 9 lbs

Answer: You will get 9 lbs of raspberry.

The amount of fresh berries that contain 80% water is 7.2 pounds.

Amount of water in fresh raspberry = 80%

It means the amount of raspberry only in a fresh raspberry =20%

Amount of water in dry raspberry =20%

What is a percentage?

A percentage is a value per hundred.

So, the amount of raspberry only in 36 lbs fresh berries = 20% of 36

20% of 36 = (20/100)*36 = 7.2 lbs

So, the amount of raspberry only in 36 lbs of fresh berries = 7.2 lbs

Therefore, we get 7.2 lbs from 36lb fresh berries.
