If 1/6 of the vacationers visited the amusement park and 1/15 of those rode the Ferris wheel, what fraction of the vacationers rode the Ferris wheel? (for my sisters math class)

1/90.

Step-by-step explanation:

To get the answer, just multiply 1/6 and 1/15 together.

1/6 * 1/15 = 1/90.

Therefore, 1/90 of the vacationers rode the Ferris wheel.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
