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

May you solve this for me?
shusha [124]

Answer: 23.94 cm

Step-by-step explanation: I am totally not sure if this is the answer, but think of it this way: Those are 2 semi circles. The formula for the area of a semi circle is A = π * r^2 / 2. For the semi circle with 6 cm, the radius is 3. So we can plug it in the formula. 3.14 * 3^2 / 2, which is 14.13. For the semi circle with 5 cm, the radius is 2.5. Again plug it in and it will be 3.14 * 2.5^2 / 2, which is 9.8125. Then, to get the total area, add the 2 final values together. 9.8125 + 14.13, which is 23.9425. Then it said "round to the nearest hundredth if necessary. We can round to the nearest hundredth, which is 23.94, so that would be the answer. That is just my thought process.

I am not really sure if it's the answer, but take a gander at my thought process and hopefully, you can agree with me.
