Answer:

This population, the population is 45 fish.

Step-by-step explanation:

This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

x= 60*0.75

x=45

This population, the population is 45 fish. Please make the brainliest.

60-25% of 60 =number of fish this year

60-25/100 x 60

60-15

45 fish are present in the lake

Answer:

15 feets per second

Step-by-step explanation:

Given that:

Distance traveled by plane = 300 feets

Time taken by plane to travel such distance = 20 seconds

Rate at which the plane is diving is obtained thus :

Distance / time

= 300 feets / 20 seconds

= 15 feets / second

Hence, the plane is diving at a rate of 15 feets per second.

Answer:

-∞ < y < ∞

Step-by-step explanation:

Range corresponds to the values on the y-axis and Domain corresponds to values on the x-axis. Here if see the graph the range depends on values on y-axis and we can see that the the graph goes to -∞(-negative infinity) to +∞(positive infinity)  so the answer is

-∞ < y < ∞

Answer:

The range is  -∞< y < ∞, below is the explanation of how to get range.

Step-by-step explanation:

Given:

      Graph of a function h(x).

To find:

      The range of the function in inequality notation.

The range is all possible y-values of the function. Let's find all possible y values from the graph.

If we see the graph, it has a vertical asymptote at x=1 and a slant asymptote.

But it tool all y values from -infinity to infinity.

So, we can write range as -∞< y < ∞ because both sides of the function go and so on below the x-axis and go and so on above the x-axis.

The range is  -∞< y < ∞ .

Answer:

9 cm

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon.

If a polygon is a triangle, and its 3 sides have length a, b, and c, then the perimeter is the sum of a, b,, and c.

perimeter = a + b + c

Here, the perimeter = 29 cm

The lengths of the sides are a = 8 cm, b = 12 cm, c = x.

8 + 12 + x = 29

x + 20 = 29

x = 9

Answer: 9 cm

The best deal is 25 lbs for $13.59

Step-by-step explanation:

A) 4 lbs for $2.37

Units price (price per lb) = $2.37 / 4

= $0.5925

Approximately $0.59

b) 15 lbs for $8.57

Price per lb = $8.57 / 15

= $0.5713

Approximately $0.57

c) 25 lbs for $13.59

Price per lb = $13.59 / 25

= $0.5436

Approximately $0.54

b. Use sigma notation to represent the number of seats in the theater.

Answer:

11 and 12

Step-by-step explanation:

Let the consecutive integers be x and x+1

The lesser integer = x

The greater integer = x+1

Two times the greater of two consecutive integers is expressed as;

2(x+1) = 2x+2.

9 less than three times the lesser integer is expressed as;

3x - 9

Equate both expression

2x+2 = 3x - 9

2x-3x = -9-2

-x = -11.

x = 11

The greater integer = x+1 = 11+1 = 12

Hence the integers are 11 and 12

Answer:

Phone used 11,500 centimeters of yarn

Step-by-step explanation:

So first we know that 1 meter is equivalent to of 100 centimeters

Now lets convert everything into centimeters

197*100=19700

And thats it

Now we know she started with 19700 centimeters of yarn and has 8200 centimeters left over.

We can make an equation

We can make “x” stand for amount of yarn used.

19700-x=8200

Minus x becuase thats how much she used and equal 8200 becuase Thats what was left over

Now use inver operations

-x=-11,500

Now divide - on both sides

x=11,500

She used 11,500 centimeters of yarn

Answer:

24.04%

Step-by-step explanation:

Given that:

Mortgage = $238,000

Number of years = 30

Monthly payment without extra payment= $1220.09

Monthly payment with extra payment = $1420.09

Total amount paid :

Number of months * monthly payment

12 months = 1year

30 years = (30 * 12) = 360 months (without extra payment)

22 years 5 months = (22 * 12) + 5 = 269 months (with extra payment)

Amount paid without extra payment :

$1220.09 * 360 = $439232.4

Percentage of total loan paid as interest :

((439232.4 - 238000) / 238000) * 100%

= 0.8455142 = 84.55%

Amount paid with extra payment :

$1420.09 * 269 = 382004.21

Percentage of total loan paid as interest :

((382004.21 - 238000) / 238000) * 100%

= 0.6050597 = 60.51%

Difference between percentages:

84.55% - 60.51% = 24.04%

Answer:

The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 is 5/7

Step-by-step explanation:

The given numbers are;

0, 1/3, 1/2, 3/5, and 2/3

The number sequence is formed adding [tex]\dfrac{1}{\left (\dfrac{n^2 + n}{2} \right ) }[/tex] to each (n - 1)th term to get the nth term number in the sequence, with the first term equal to 0, as follows;

For the 2nd term, the (n - 1)th term is 0, and n = 2, gives;

The

[tex]0 +\dfrac{1}{\left (\dfrac{2^2 + 2}{2} \right ) } = 0 + \dfrac{1}{3} = \dfrac{1}{3}[/tex]

For the 3rd term, the (n - 1)th term is 1/3, and n = 3, gives;

[tex]\dfrac{1}{3} +\dfrac{1}{\left (\dfrac{3^2 + 3}{2} \right ) } = \dfrac{1}{3} + \dfrac{1}{6} = \dfrac{1}{2}[/tex]

For the 4th term, the (n - 1)th term is 1/2, and n = 4, gives;

[tex]\dfrac{1}{2} +\dfrac{1}{\left (\dfrac{4^2 + 4}{2} \right ) } = \dfrac{1}{2} + \dfrac{1}{10} = \dfrac{3}{5}[/tex]

For the 5th term, the (n - 1)th term is 3/5, and n = 5, gives;

[tex]\dfrac{3}{5} +\dfrac{1}{\left (\dfrac{5^2 + 5}{2} \right ) } = \dfrac{3}{5} + \dfrac{1}{15} = \dfrac{2}{3}[/tex]

For the next or 6th term, the (n - 1)th term is 2/3, and n = 6, gives;

[tex]\dfrac{2}{3} +\dfrac{1}{\left (\dfrac{6^2 + 6}{2} \right ) } = \dfrac{2}{3} + \dfrac{1}{21} = \dfrac{15}{21} = \dfrac{5}{7}[/tex]

The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 = 5/7.
