Kure wants to share three pies among 11 people. Her calculator shows 0.272727272727. Determine whether the rounding should occur and give the rounded answer

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

it is a secret for it not to be compromised sorry

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
