The number that rode in columns was 3 2/3 times the number that rode in rows. If 2200 rode in columns, how many rode in rows?
melamori03 [73]

Answer:

600

Step-by-step explanation:

Given parameters:

    Number that rode in columns = 3\frac{2}{3} times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = \frac{11}{3}R

Number of people that rode in rows  = 2200;

            2200 =  \frac{11}{3}R

             11R  = 2200 x 3

                R  = \frac{2200 x 3}{11}

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

A triangle has one leg that is 8, one leg that is 15 and a hypotenuse that is 20. Is it a right triangle?
gregori [183]

Answer:

No

Step-by-step explanation:

A^2+b^2=c^2

8^2+15^2=20^2

64+225=400

289=400

289 does not equal 400 so it is not a right triangle

I can't figure this one out...
worty [1.4K]

Answer:

the area would be 36(pi) since you can't find out the exact value of pi (22/7) and where it would terminate so thats the most exact answer you can get. The circumference would be

Step-by-step explanation:

12/2 = 6

Area = (pi)radius^2

6^2 = 36

36(pi)

Circumference: (pi)d

12(pi)


For approximate area you multiply r^2 by 3.14

For approximate circumference you multiply diameter by 3.14
