What is the distance between the points (4,9) and (14, -11)? Round to the

maks197457 [2]

Answer: 22.4

Step-by-step explanation:

The distance formula can be used to solve this problem.

$D=\sqrt{(x_{2}-x_{1} )^2+(y_{2}-y_{1} )^2}$

We can plug in our x and y values to find the distance.

$D=\sqrt{(14-4)^2+(-11-9)^2}$

$D=\sqrt{10^2+(-20)^2}$

$D=\sqrt{100+400}$

$D=\sqrt{500}$

$D=22.4$

Our distance between the points is 22.4.

What is the measure of each interior angle of a regular decagon (10 sides)?

bixtya [17]

6)a

if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is
$\frac{(n - 2) \times 180}{n}$
so the answer will be
$\frac{(10 - 2) \times 180 }{10} = \frac{1440}{10} = 144$
they each measures 144 degrees

good luck

Temka [501]

Answer:

6 minutes

Step-by-step explanation:

Set up the proportion as these two fractions equal to each other

9/3 = 18/x

2. Cross multiply so that 9*x=18*3

3. 9x=54, so now you divide 54 by 9

and this will give you

4. x= 6, so it will take 6 minutes to fill

up the 18 gallon pool

Hope this helped!
