Answer:
2 wholes and 5/26
Step-by-step explanation:
convert the mixed number to improper fraction
= -19/6 / -13/9
since there is 2 negatives and (-)/ (-) means your answer is positve
to divide by a fraction multiply by the reciprocal of that fraction.
19/6 x 9/13
reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.
19/2 x 3/13
multiply 19/2 x 3/13
= 57/26
= 2 wholes and 5/26
= 2.1923076
Answer:x^3+13x^2+3
Step-by-step explanation:
(2x^3+11x^2+5)-(x^3-2x^2+2)
Clearing brackets
2x^3+11x^2+5-x^3+2x^2-2
Collect like terms
2x^3-x^3+11x^2+2x^2+5-2
x^3+13x^2+3
The given info is sufficient to warrant the conclusion that both triangles are 45-45-90 triangles.
The measure of angle B is 45 degrees, or pi/4 radians.
The cosine of this angle B is 1/√2, or √(2)/2. This is approx. 0.707.
11/26 chance that the student plays both instruments.
First, add the amount of students that just play flute or piano:
3 + 5 = 8
Then add 8 to the amount that does not play either instrument:
8 + 7 = 15
Then do:
26 - 15 = 11
Then place 11 over the amount of people:
11/26
