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

The formula used to find the length of a line segment is the same formula as the Pythagoras theorem.

We take CD as the hypotenuse of the right-angled triangle and the distance between the x-coordinates and y-coordinates as the length of two short sides.

We can write the formula as
CD = \sqrt{( x_{1}- x_{0})  ^{2}+ ( y_{1}- y_{0})  ^{2}  }
CD = \sqrt{(a-0)^{2}+ (b-b)^{2}  }

leva [86]

Answer:

  Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%

Explanation:

  Let number of students be 100.

  At Taylor Street School, 40% of the students bought lunch in the cafeteria today

 Number of students bought lunch = 100 x 40/100 = 40

 Of the students who bought lunch in the cafeteria today, 30% chose pizza as their entree

 Number of students bought pizza = 40 x 30/100 = 12.

 Probability of an outcome = Number of favorable outcome/ Total number of outcome

 Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = Number of students bought pizza/Total number of students

        = 12/100 =0.12 = 12%

  Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%
