What is the ratio of the circumferences for two circles with areas 6π m2 and 150π m2?

hichkok12 [17]

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{Area_1}{Area_2}\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{6 \pi }{150 \pi }\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{1 }{25}\bigg)
$

$\dfrac{Length_1}{Length_2} = \sqrt{ \dfrac{1}{25} } 
$

$\dfrac{Length_1}{Length_2} = \dfrac{1}{5}$

-------------------------------------------------------------
Answer: The ratio of the two circles = 1 :5

Solve using substitution for x and y 5x+y=16 y=2-3x

valentina_108 [34]

Answer:

X = 7 Y = -19

Step-by-step explanation:

If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this

5x + 1(2-3x)=16

Apply distributive property to solve.

Once you find x, plug it in to find y

To double check your work, you can plug the coordinated values back in

-19 = 2 - 3(7)

-19 = 2-21

This is true, so our solution is correct.

Hope this helps :)
