On her multiple choice math test, 1720 of Lydia's answers are correct. What is the ratio of correct to incorrect answers for Lydia on her test?

or 17:3

Step-by-step explanation:

Since Lydia got 17 out of 20 questions correct, that means she got 3 out of 20 incorrect. To get the ratio of correct (17) to incorrect (3) answers, we can simply divide the two numbers as follows:

or 17:3

Since this ratio is already in simplest terms, this is the final answer.

approximately 69.93

Step-by-step explanation:

So the square root of 8 is about 2.8,

the square root of 12 is about 3.5, '

add those and you should get 6.3

since your multiplying, you should solve for the other expression in the parenthesis as well

the square root of 48 is equal to about 6.9

the square root of 18 is around 4.2,

add those and you should get 11.1,

When you multiply 11.1 and 6.3, you should wind up with 69.93, since we rounded a lot, this is only an approximation :)

Thank you for the generous amount of points btw :)
