B because absolute value means that the number inside the absolute value brackets is the positive version of the number
Answer:
66 feet
Step-by-step explanation:
Mayra wants to place tiles on the edge of pool, i.e, on the circumference of the circular part
so the length required will be ,2πr
radius=21/2 feet=10.5feet
now req lenght = (2π10.5)=66 (feet)
14+5= 19; 19-8=11. the hotel elevator is now on the 11th floor
Answer:
11. The student put 24 as the diameter instead of the radius.
12. 48 pi
Step-by-step explanation:
The formula for the circumference of a circle is c = pi x diameter.
However, the question says that the radius is 24m, not the diameter.
To fix it, all you need to to is double the radius to get 48m for the diameter.
48 x pi = 48 pi
Answer: 
Step-by-step explanation:
By the Intersecting Secants Theorem, we know that:

Having this, we can find the value of "x" by solving for "x":
Applying Distributive property:

Subtract 25 from both sides of the equation:

And finally dviding both sides of the equation by 5, we get:
