Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?

The two populations will be the same after _____
years.

Answer:

y = 5

Step-by-step explanation:

4×(x -3y = -6 ) ➡ 4x - 12y = -24

4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15

y = 5 use this value to find x

x - 3×5 = -6

Step-by-step explanation:

The price of a game discounted by 18% is 0.82x cuz 82% is left

the price of the toy is 1.18x because x + 0.18x

the volume of water is  7/10x because 7/10 is left

the total amount of flour is 13/10x because 10/10x + 3/10x

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

2x - 2 = 45 + x

2x - x = 45 + 2

x = 47°

Answer:

x = 47

Step-by-step explanation:

Finding the third angle (y) of the triangle:

- Since angles on a straight line add up to 180:

2x -2 + y = 180

y = -2x + 2 + 180

= -2x + 182

Hence, the third angle of the triangle is -2x + 182.

Since all 3 angles of a triangle add up to 180°:

-2x + 182 + x + 45 = 180

-2x + x + 227 = 180

-2x + x = 180 - 227

-x = -47

x = 47

Hence, x = 47

Answer:To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...

To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Step-by-step explanation:

Answer:

y=-x+3.

Step-by-step explanation:

The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = [tex]\dfrac{51}{8}[/tex]

[tex]=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}[/tex]

Hence, 51 notes span 6 octaves.

Answer:

230500×100/8= 2881250

Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.

System:

d= 5(0.75-t)

d= 20t

20t = 3.75 -5t

Define Variables:

d = how far Carol Skied

t = time it took Carol to go up/down

Solve:

20t = 3.75 -5t

20t + 5t = 3.75 -5t + 5t            

25t = 3.75

25t/25 = 3.75/25

t = 0.15

Now we plug in the time into the Distances:

20t = 3.75 - 5t

20(0.15) = 3.75 - 5(0.15)

3 = 3.75 - 0.75

3 = 3

Solution as Sentence:

Carol Skied 3 miles

P + t -7 =6

10+3-7=6

10+3=13

13-7=6

P=10 t=3

The values of the numbers p and t will be 10 and 3 respectively.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The value of the numbers will be calculated as:-

P + t -7 =6

10+3-7=6

10+3=13

13-7=6

P=10 t=3

Therefore, the values of the numbers p and t will be 10 and 3 respectively.

Answer: I Believe 15%, But I'd Double Check.

Answer:

ermm there should be an other equation right?

Answer:

x = 9

Step-by-step explanation:

combine all the equations and set it equal to 360

10x+ 7 + 88 + 127 + 5x+3 = 360

then combine like terms

15x + 225 = 360

then solve the equation by moving 225 to the right side of the equation

15x = 135

divide both sides by 15

x = 9

Answer:

7

Step-by-step explanation:

A square has 4 sides, all of equal length. We can simply find the square root of the area to find the length and width, or length of each side. So to find the length, you find the square root of the area.

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

[tex]3x + x + 10 + 5x + 2x + 2 = 56[/tex]

Now we combine like terms

[tex]3x+x+5x+2x+10+2=56[/tex]

[tex]11x+12=56[/tex]

We subtract both sides by 12 to get,

[tex]11x=44[/tex]

now we divide both sides by 11

[tex]x=\frac{44}{11}[/tex]

[tex]x=4[/tex]
