Answer: 285

Step-by-step explanation:

We know that 15 out of 45 dogs are puppies. Let's turn that into a fraction. 15/45. Now we also know that they collect 855 dogs each year, but we don't know how many puppies. The fraction for that would be x/855. (Puppies = X)

Now all we have to do is cross multiply. 15 × 855 is 12825.

12825 ÷ 45 is 285.

So, the number of puppies is 285.

Find the distance between these points. C(0, 4), T(-6, -3) √(37) √(109) √(85)
finlep [7]

Answer:

The answer is

<h2>\sqrt{85}</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{( {x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

C(0, 4), T(-6, -3)

The distance between them is

<h3>|CT|  =  \sqrt{ ({0 + 6})^{2}  +  ({4 + 3})^{2} }  \\  =  \sqrt{ {6}^{2} +  {7}^{2}  }  \\  =  \sqrt{36 + 49}</h3>

We have the final answer as

<h3>\sqrt{85}</h3>

Hope this helps you

The ages of​ Edna, Ellie, and Elsa are consecutive integers. The sum of their ages is <br> 108.
Alina [70]
Let x = Edna's age

then it follows that  (x + 1) is Ellie's age and (x + 2) is Elsa's age

We can now write and equation for the sum of their ages equal to 108:
x + (x + 1) + (x +2) = 108  simplify the left side
3x + 3 = 108 subtract 3 from both sides
3x = 105   divide both sides by 3
x = 35
Edna is 35,  Ellie is 36, and Elsa is 37
