There are 5 black keys for each 7 white keys. Hence, the ratio stands at 5:7. To determine how many black keys correspond to 49 white keys, we calculate the scaling factor for the ratio: 49 divided by 7 equals 7. Thus, the original ratio is scaled by 7. Therefore, the total number of black keys equals 5 multiplied by this scaling factor, resulting in 35 black keys.
La familia Freeman:
13 c/kWh (400 kWh) + 2 c/kWh (400 kWh) + 14.5 c/kWh) 450 kWh
= 6464.5 c
6464.5 c x 30 = 193935
La familia Baum:
8.5 (400) + 12 (400) + 14.5 (450)
= 14725 c

The greatest common factor shared by 32 and 44 is 4. This is factored out as follows: 4(8 + 11) = 4(8 + 11), which appears strange to me, but that's how most textbooks illustrate the factoring process.
I believe there are 1,600 students enrolled in metaphysics.
Answer:
AC and OA
Step-by-step explanation:
-A secant refers to a line that intersects two points on a circle.
-We have a square OABC with each side measuring 6cm and a circle with radius r=5cm, centered at O. The circle's radius is shorter than the side of the square:
-The circle intersectsOA andOC, while it does not intersect AB and BC.
Therefore, AC and OA serve as secants for the circle.
