Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • percent
  • percentage words problem
  • PEMDAS
<h3>given:</h3>
  • population:2500
  • decreasing rate:3%
<h3>to find:</h3>
  • the population after 11 years
<h3>let's solve:</h3>

according to the question

population decreases in 1 year

2500 \times 3\% \\ 2500 \times  \frac{3}{100}  \\ 25 \times 3 \\ 75

population will decrease in 11 years

  • 75×11
  • 825

so the population of the town after 11 years will be

2500-825

I need help but I need the correct answer everyone is giving me the wrong answer !!
Jlenok [28]

Answer:

y - 2 = 6 (x - 1)

Step-by-step explanation:

Slope intercept form equations look like this:

y - y1 = m (x - x1)

***m = \frac{y2-y1}{x2-x1}

Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:

y - 2 = m (x - 1)

To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6

Now that we know m = 6, let's plug that back into the original equation to get our final answer:

<u>y - 2 = 6 (x - 1)  </u>          

I hope this helps!

Turtles can live a long time. This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalam
madreJ [45]

Answer:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

The average age  is  22 yrs

The sum  of the ages  is  440 yrs

When  two  of the turtles leave, the average is  21 yrs....and there are 18 turtles left

So....the sum of the ages is  21 * 18  = 378

And the difference  in the sums  is  62

The only two values that sum to 62  are  26 and 36

So.....the box turtle must have been 36 and the map turtle must have been 26

5/8 + 1 1/4 = x/10<br> solve for x
lara [203]

Answer:

<em>x = </em><em>7</em><em>5</em><em>/</em><em>4</em>

Step-by-step explanation:

<em>5/8 + 1 1/4 = x/10</em>

<em>5</em><em>/</em><em>8</em><em> </em><em>+</em><em> </em><em>5</em><em>/</em><em>4</em><em> </em><em>=</em><em> </em><em>x/</em><em>1</em><em>0</em>

<em>1</em><em>5</em><em>/</em><em>8</em><em> </em><em>=</em><em> </em><em>x/</em><em>1</em><em>0</em>

<em>8</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em><em>×</em><em> </em><em>1</em><em>0</em>

<em>8</em><em>x</em><em>/</em><em>8</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em>0</em><em>/</em><em>8</em>

<em>x </em><em>=</em><em> </em><em>1</em><em>5</em><em>0</em><em>/</em><em>8</em>

<em>x </em><em>=</em><em> </em><em>7</em><em>5</em><em>/</em><em>4</em>
