Plz will give 40 points! astronomers observed a planet orbiting a distant star. they expected the planet to orbit the star approximately 1 7/8 times every 4 earth years. about how many earth years will it takr the planet to orbit the star once? a. 15/32 b. 7 1/2 c. 2 2/15 2/15

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
