The hula hoop rolls 879 cm.

Answer:

879.2 cm

Step-by-step explanation:

The distance around the hula hoop is given by the circumference.  The formula for the circumference of a circle is

C = 2πr

Using 3.14 for pi and our value of 35 as r, we have

C = 2(3.14)(35) = 219.8

For 4 rotations, this gives us a distance of

219.8(4) = 879.2 cm

-36 - 6x (-6) + 4
next you will multiply the numbers
-36 + 36 + 4

A sports store received a shipment of 150 footballs and basketballs. 20% were basketballs. How many footballs were in the shipme
RideAnS [48]
0.20(150) = 30 basketballs were in the shipment. Since the shipment presumably comprised only footballs and basketballs, the remainder of the shipment must consist of footballs.

150 - 30 = 120 footballs were in the shipment.

What's the standard equation of the circle with the general equation x2 + y2 + 4x – 2y – 20 = 0? answers: 1) (x + 2)2 + (y – 1)2
gizmo_the_mogwai [7]

Answer:

4).  (x + 2)^2 + (y - 1)^2 = 25.

Step-by-step explanation:

x^2 + y^2 + 4x - 2y - 20 = 0

x^2 + 4x + y^2 - 2y = 20

Completing the square on the x and y terms:

(x + 2)^2  - 4 + (y - 1)^2 - 1 = 20

(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1

(x + 2)^2 + (y - 1)^2 = 25.
