Answer:
600
Step-by-step explanation:
Given parameters:
Number that rode in columns = 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 = R
Number of people that rode in rows = 2200;
2200 = R
11R = 2200 x 3
R =
R = 200 x 3
R = 600
Number of people that rode in rows = 600
Answer:
20%
Step-by-step explanation:
Value increased in 5 years = £95000 - £80000 = £5000
Value increase in 1 year =5000/5 = 1000
Increase % = (1000/5000 ) * 100 = (1/5) *100 = 20%
U-value is generally used to rate door or window units. The lower the U-Value, the more energy efficient the system in question will be. A U-value is typically a low number because it is a rating of how much heat energy is lost or gained. If we look at the two values mathematically, U-value is the reciprocal of R-value; that is, U = 1/R and R = 1/U.

Answer:
(x-4)^2+(y-4)^2=25
Step-by-step explanation:
the standard equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) are the coordinates of the center and r is the radius. In your case, just plug your the numbers into the equation
