There was 10 black bears in an area.some years later ,there were 17 black bears in the area.what is the percent gain

Answer:

85

Step-by-step explanation:

Answer:

$3.25

Step-by-step explanation:

So,

If a package of 17 sliced apples is $2.21, lets find out the price per apple.

2.21 / 17 = 0.13

so, the price per apple is $0.13

Now, we find the price of a package with 25 sliced apples.

0.13 x 25 = 3.25

So, the price of a package with 25 sliced apples is $3.25

The given series is :[infinity] n = 3 11n − 10 n2 − 2n.The general form of the given series is ∑ (11n−10)/(n2−2n). The series is given as ∑ (11n−10)/(n2−2n). Thus, the given series is a fraction series. To determine whether the series is convergent or divergent, we can use the ratio test of convergence.

The ratio test of convergence states that if the limit of the ratio of the n+1th term and nth term is less than 1, then the given series converges and if the limit of the ratio of the n+1th term and nth term is greater than 1, then the given series diverges. The ratio test is inconclusive if the limit of the ratio of the n+1th term and the nth term is equal to 1. Let's apply the ratio test of convergence for the given series: Let a_n = (11n−10)/(n2−2n)and a_n+1 = (11n+1−10)/[(n+1)2−2(n+1)] = (11n+1−10)/(n2+n-2)Thus, the ratio of the n+1th term and nth term of the given series is as follows: limit as n approaches infinity of (a_n+1)/(a_n)=[(11n+1−10)/(n2+n-2)]/[(11n−10)/(n2−2n)]=[(11n+1−10)/(n2+n-2)]*[(n2−2n)/(11n−10)]=lim n→∞ [11n+1n2+n−2(11n−10)]×[(n2−2n)11n−10]=lim n→∞ [(11n+1)(n−2)(n+1)(n−1)(n+1)]/(11n(n−2)(n2−2n)(n+1))=lim n→∞ [(11n+1)(n−2)/(11n(n−2))]×[(n+1)/(n−1)]×[(n+1)/(n2−2n)]The terms n−2 and 11n are omitted because they cancel each other. The given series is convergent because the limit of the ratio of the n+1th term and the nth term is less than 1. In conclusion, the main answer to this question is that the given series is convergent. The proof is based on the ratio test of convergence, where the limit of the ratio of the n+1th term and nth term of the given series is less than 1.

Total number of ticket = 16

The given lines of equations are not perpendicular to each other. Therefore, `θ = cos⁻¹(8/(4√10))` which is approximately `28.07°`.Since `θ ≠ 90°`, the given lines of equations are not perpendicular to each other.

Given lines of equations:

x = −2 + 2t, y = −6, z = 2 + 6tx=−1+t,y=1+t,z=t, t∈ R.

Firstly, we need to find the direction vectors of the two given lines.For the first equation,Let `t=1`, then the point on the line is `(-2+2(1), -6, 2+6(1))`=`(0, -6, 8)`.

Let `t=2`, then the point on the line is

\(`(-2+2(2), -6, 2+6(2))`=`(2, -6,\)14)`.T

herefore, direction vector `

\(v1 = (2, -6, 14)-(0, -6, 8)`=`(2, 0, 6)`\)

For the second equation, direction vector \(`v2 = (1, 1, 1)`.\\\)

Let the angle between the direction vectors `v1` and `v2` be `θ`.

Then, we know that `v1 • v2 = |v1||v2| cosθ`, where `•` represents the dot product of the vectors, and `|.|` represents the magnitude of the vector.

Thus, we have:

(2, 0, 6) • (1, 1, 1) = √(2²+0²+6²)√(1²+1²+1²) cosθ

=> 8 = √40√3 cosθ=> cosθ = 8/(4√10)

Therefore,

`θ = cos⁻¹(8/(4√10))`

which is approximately `28.07°`.

Since `θ ≠ 90°`, the given lines of equations are not perpendicular to each other.

The inverse of a function can be found by swapping the numbers in each ordered pair of the function.

When you have a function with ordered pairs, the inverse of that function can be found by reversing the order of the numbers within each pair. In other words, if you have a function f(x) with ordered pairs (a, b), the inverse function, f^ (-1) (x), will have ordered pairs (b, a). This process essentially switches the input and output values of the original function.

To find the inverse of a function, simply swap the numbers in each ordered pair, resulting in the ordered pairs for the inverse function.

Answer:

16√3

Step-by-step explanation:

I got it on test

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Answer:

A) She should buy the

Step-by-step explanation:

Part A:

For question A, we find the areas of both plots and see which one is greater.

For the first one, we do 3/8 * 2/3

\(\frac{3}{8} * \frac{2}{3} = \frac{6}{24} = \frac{1}{4}\)

The area of the first plot is 1/4 square miles

For the second one, we do 2/5 * 2/5

\(\frac{2}{5} *\frac{2}{5} = \frac{4}{25}\)

The area of the second plot is 4/25 square miles

We have 1/4 and 4/25.

To see which one is bigger, we make them have the same denominator, also known as the LCM (Least Common Multiple).

LCM(4,25) = 100

Now we make 1/4 have a denominator of 100

4 times what is 100?

25, so the numerator is 25 and the denominator is 100.

We get: 25/100

Now we make 4/25 have a denominator of 100

25 times what is 100?

4, so the numerator is 4 * 4 = 16 and the denominator is 100.

We get: 16/100

Now we can see which is bigger:

25/100 or 16/100

25/100 is bigger

Therefore, Miguel's mother should buy the plot with dimensions 3/8 and 2/3.

Part B

For part B, I'm not sure which plot of land she is going to pay for, so I will answer both.

We answered this in Part A already.

The 3/8 and 2/3 plot was 1/4 square miles and the 2/5 by 2/5 plot was 4/25 square miles.

Plot 1:

1/4 square miles

It said that it costs $750,000 for a square mile

This plot is 1/4 square miles, so we do

\($750,000 * \frac{1}{4} = \frac{750,000}{4} = 187,500\)

The cost for plot 1 is $187,500

Plot 2:

4/25 square miles

It said that it costs $750,000 for a square mile

This plot is 4/25 square miles, so we do

\(750,000*\frac{4}{25} = \frac{3,000,000}{25} = 120,000\)

The cost for plot 1 is $120,000

So for the 3/8 by 2/3 plot, it cost $187,500 and for the 2/5 by 2/5 plot costs $120,000

Answer: Graph Y

Explanation:

The parent function \(y = \sqrt{x}\) is always increasing and it has the left-most endpoint at (0,0). Replacing every x with x-1 will move that point one unit to the right to end up at (1,0)

So going from \(y = \sqrt{x}\) to \(y = \sqrt{x-1}\) shifts the entire curve 1 unit to the right. What results is shown in graph Y.

The answer to this inequality is "b < 4," which means that the variable "b" must be less than 4 for the inequality to be true.

The answer to 3b < 12 is b < 4. To get this answer, you would divide both sides of the inequality by 3, which gives you b < 4. This means that any value of b that is less than 4 will make the inequality true.
In other words, the solution set for this inequality is all values of b that are less than 4. For example, if b is 2, then 3b is 6, which is less than 12, so the inequality is true. But if b is 5, then 3b is 15, which is not less than 12, so the inequality is false. It's important to remember that when you divide or multiply both sides of an inequality by a negative number, you need to flip the direction of the inequality symbol. But in this case, we are dividing by a positive number, so the direction of the inequality symbol stays the same.
Overall, the answer to 3b < 12 is b < 4, which means that any value of b that is less than 4 will make the inequality true.
The inequality you provided is "3b < 12." To find the solution, you need to isolate the variable "b" by dividing both sides of the inequality by 3.
3b ÷ 3 < 12 ÷ 3
This simplifies to:
b < 4

What is unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams.

5 ice-creams cost is $125.

Step 1: Let's find the cost of 1 ice cream.

In order to do that, divide the total cost of ice-creams by the total number of ice-creams.

The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-

creams = 125/5 = 25.

Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams.

The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75.

Finally, we have the cost of 3 ice-creams i.e. $75.

lemonade: tea : total

1                 1    1+1=2

We need a total of 16 and divide it

The cardinality of a set refers to the number of elements in the set. If the set X has cardinality 16 and the set Y has cardinality 24, then the number of elements in set X is 16 and the number of elements in set Y is 2.

If their intersection has cardinality 21, then the number of elements that both sets have in common is 21.To determine the number of elements contained in the union of X and Y, we need to subtract the number of elements in their intersection from the sum of the cardinalities of X and Y. That is,
