Answer:
Step-by-step explanation:
(7/12) of 840 attended the concert:
(7/12)*(840) = 490 students attended the Spring Concert.
(840 - 490) = 350 did not attend
(350/840) is the fraction of students who did not attend. This can be reduced to (35/84)
(350/840) = 0.4167 or 41.67% did not attend.
=11/3×1/14
=3.67×0.07
=0.2568
x = 25√2, y = 25
x = 25(√2) = 25√2
y = 25
32.6
S=3.4(9.6)
S=32.64≈32.6
