To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.

Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>

A village wishes to measure the quantity of water that is piped to a factory during a typical morning. A gauge on the water line

anzhelika [568]

Answer:

570 m³

Step-by-step explanation:

The volume of water is the product of flow rate of water and the time taken. We are to get the volume of water used between 6 am and 9 am, that is for 3 hours (9 - 6).

We are given the flow rate at 6 am and the flow rate at 9 am, but this flow rate changes between 6 am and 9 am. To get the estimate of the water used, Let us assume that it flows at the same flow rate as it was at 6 am throughout, hence:

$V_L= 100 m^3/h * 3h=300\ m^3$

Also, let us assume that it flows at the same flow rate as it was at 9 am throughout, hence:

$V_R= 280 m^3/h * 3h=840\ m^3$

To get the best estimate of the total volume, let us find the average of the two values, hence:

$Volume=\frac{V_L+V_R}{2} =\frac{300+840}{2}=570\ m^3$

-1/4 + (-3/7) what is the answer???

SVEN [57.7K]

Find the Least Common Denominator (LCD) which is 28.

-1/4 (7) = -7/28

-3/7 (4) = -12/28

-7 - 12 = -19

-19/28

Simplify if you can.

plot the reflection of point A across the x-axis. what are the coordinates of the reflection of point A across the x-axis? what

dsp73

You reflect point A over the x-axis, double the distance from point a to the x-axis, then give the coordinates.

ex/ point A to the x-axis: 6, reflection: 12. coordinates (-6, 5)
