Answer:
Step-by-step explanation:
45
Given that the chords intersect at the center, you conclude that they both are diameters.
Now, you have that the point p is the intersection point, so it is the center of the circle.
Then, the length of CP is the radius of the circle, and also the lenght of PB is the radius.
So, the length of CP is equal to the length of PB, and it is 8.
Answer: 8.
Answer:
28 divided by 8 = 3.5
Step-by-step explanation:
36 divided by 15 is 2.4, 32 divided by 14 is 2.29, 30 divided by 12 is 2.5, and 28 divided by 8 is 3.5. The greatest quotient comes from 28 divided by 8 which is 3.5
First distribute, so multiply 1/4 * 2x, 1/4 * -12, 2/3*3x, and 2/3 * 9
1/2x - 3 = 2x + 6
Simplify
-9 = 1 1/2x
Divide
x = -6
The x in the formula is the depth.
You are given two different depths, replace x with the depths, solve for T, then subtract the to find the difference:
At 1200 meters the temperature is:
T = 4500/1200 = 3.75 degrees
At 3750 meters the temperature is:
T = 4500 / 3750 = 1.20 degrees.
The difference in temperature between the two depths is:
3.75 - 1.20 = 2.55 degrees C.
