Answer:

Adélie penguins= 826,680

Step-by-step explanation:

Giving the following information:

Total penguin population= 1,503,054

Adélie penguins= 55%

To calculate the number of Adélie penguins, we need to use the following formula:

Adélie penguins= total penguin polulation*proportion of Adélie penguins

Adélie penguins= 1,503,054*0.55

Adélie penguins= 826,680

Answer:

Step-by-step explanation:

1). 10 = [tex]\frac{1+7x}{7+x}[/tex]

   10(7 + x) = 1 + 7x

   70 + 10x = 7x + 1

   10x - 7x = 1 - 70

   3x = -69

   x = -23

2). 0.2 = [tex]\frac{6+2x}{12+x}[/tex]

    0.2(12 + x) = 6 + 2x

    2.4 + 0.2x = 6 + 2x

    2.4 - 6 = 2x - 0.2x

    1.8x = -3.6

    x = -2

3). 0.8 = [tex]\frac{x}{x+0.5}[/tex]

    0.8(x + 0.5) = x

    0.8x + 0.4 = x

    x - 0.8x = 0.4

    0.2x = 0.4

    x = 2

4). 3.5 = [tex]\frac{4+2x}{0.5-x}[/tex]

    3.5(0.5 - x) = 4 + 2x

    1.75 - 3.5x = 4 + 2x

    -3.5x - 2x = 4 - 1.75

    -5.5x = 2.25

     x = -[tex]\frac{2.25}{5.5}[/tex]

     x = - [tex]\frac{9}{22}[/tex]

Answer:

Step-by-step explanation:

8x-192=96

8x-192+192=96+192

8x=288

8x/8=288/8

x=288/8

36

The unknown number is 204.

Important Information:

Let [tex]x[/tex] be the unknown number.

Sum of a number and -192 is

[tex](x+(-192))=x-192[/tex]

Eight times the sum of a number and -192 gives 96.

[tex]8(x-192)=96[/tex]

Divide both sides by 8.

[tex]x-192=12[/tex]

[tex]x=12+192[/tex]

[tex]x=204[/tex]

Therefore, the unknown number is 204.

A = πr²

make r subject of the formula

divide both sides by π

A/π =r²

square root both sides

r=√A/π

step two:

r=3.43ft

Answer:

Step-by-step explanation:

The total number of fives bills is 12 and the total number of tens bills is 18 and this can be determined by forming the linear equations.

Given :

Sarah has 30 bills in her wallet worth $240, all fives and tens.

The following steps can be used in order to determine the total number of fives bill and tens bills:

Step 1 - Let 'x' be the total bills of fives and 'y' be the total bills of tens.

Step 2 - The linear equation that represents the total number of bill is given by:

x + y = 30

x = 30 - y        --- (1)

Step 3 - Now, the linear equation that represents the total amount of the bill is given by:

5x + 10y = 240     ---- (2)

Step 4 - Substitute the value of 'x' in equation (2).

5(30 - y) + 10y = 240

150 - 5y + 10y = 240

5y = 90

y = 18

Step 5 - Substitute the value of 'y' in equation (1).

x = 30 - 18

x = 12

So, the total number of fives bills is 12 and the total number of tens bills is 18.

Step-by-step explanation:

Since the marked angle is between the marked sides, and the corresponding sides are marked as congruent, the two triangles are congruent by SAS (side angle side).

Answer: first one

Step-by-step explanation:

Answer:

First one

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

Firstly, under the rule of opposite vertical angles, you know that any angles opposite of each other in a cross section have the same degree measure.

Therefore the last remaining angle in the triangle will be 85 degrees, since it is vertically opposite of the 85 degree angle.

Next, you know that all three angles of a triangle MUST equal 180 degrees to be considered a complete triangle.

Therefore, use the equation below to solve for x:

180 = 54 + 85 + (48 + x)

x = 180 - 54 - 85 -48 = -7

Your total monthly payment would be; 1,500 dollars.

Monthly Rent means the monthly installments of the Annual Minimum Rent and the estimated annual utility bills payable by the Lessee under this Rental Agreement.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

We are given that  You have a gross lease of $1,000 per month. Also, Taxes and maintenance total $500 per month.

we need to calculate the your total rent payment.

Therefore, we know that;

Rent= base payment + percent of revenue

       = 1,000 + 500

       = 1500

Hence, we can conclude that the monthly rent should be 1500 dollar.

Answer: 12%

Step-by-step explanation:

Answer:

12, 16, and 20

Step-by-step explanation:

These are the answers because:

1) Composite numbers mean numbers that are divisible by more than two numbers (1 and itself).

2) Multiples of 4 that are greater than 10 are: 12, 16, and 20 because they are all divisible by more than two numbers, they are greater than 10, and they are mutiples of 4. You can check if they are multiples of 4 by skip counting or multiplying: 4, 8, 12, 16, 20 or 4 x 1 = 4, 4 x 2 = 8, 4 x 3 = 12, 4 x 4 = 16, 4 x 5 = 20.

Therefore, the answers are: 12, 16, and 20

Answer:

option D is true.

Step-by-step explanation:

The right-angled triangle is shown.

From the right-angled triangle,

The angle Ф = 60°

We know that the trigonometric ratio

tan Ф = opposite / adjacent

Thus,

tan 60 = 4 / n

√3 = 4/n

n = 4/√3

Thus,

n = 4/√3

  = (4 × √3) / (√3 × √3)

  = 4√3 / 3

Thus,

n  = 4√3 / 3

Using Pythagorean theorem

m = √n²+4²

[tex]m=\sqrt{\left(4\cdot \frac{\sqrt{3}}{3}\right)^2+4^2}[/tex]

[tex]m=\sqrt{\frac{4^2}{3}+4^2}[/tex]

[tex]m=\sqrt{\frac{64}{3}}[/tex]

[tex]m=\frac{8}{\sqrt{3}}[/tex]

[tex]m=\frac{8\sqrt{3}}{3}[/tex]

Thus,

Therefore, option D is true.

Answer:

The three consecutive POSITIVE ODD integers are: 3, 5 and 7

Step-by-step explanation:

If x is an integer, then there consecutive positive odd integers are:

x , x + 2, x + 4 are three consecutive integers.

Where

First integer, a = x

Second integer, b = x + 2

Third integer, c = x + 4

We are told to:

Find three consecutive POSITIVE ODD integers such that when you multiply the first and third the result is nine less than six times the second integer.

Hence, this is represented as:

a × c = 6(b) - 9

Where

a = x

b = x + 2

c = x + 4

x (x + 4 ) = 6(x + 2) - 9

x ² + 4x = 6x + 12 - 9

x² +4x - 6x - 12 + 9= 0

x² - 2x - 3 = 0

Factorising

x² +x - 3x - 3 = 0

x (x + 1) -3(x + 1) = 0

(x - 3) (x + 1) = 0

x - 3 = 0

x = 3

x + 1 = 0

x = -1

Since, x cannot be negative for this question, x = 3

First integer, a = x = 3

Solving for:

Second integer, b = x + 2

b = 3 + 2 = 5

Solving for :

Third integer, c = x + 4

c = 3 + 4 = 7

Therefore, the three consecutive POSITIVE ODD integers are: 3, 5 and 7
