So hmmm notice the picture below

recall the "inscribed angle" theorem, an angle inscribed is half the intercepted arc

now, the line BA goes through the center, and to each end, thus is a diameter, the point of tangency, where a tangent hits the diameter or radius of a circle, is always a right-angle

s2008m [1.1K]

Question:

The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London

Answer:

Arrival = 7:24pm

Step-by-step explanation:

Given

Distance = 195\ miles

Speed = 50mi/hr

Take\ off = 3:30\ pm

Required

Determine the time of arrival

First, we need to calculate the time to complete the journey.

Speed = \frac{Distance}{Time}

Make Time the subject

Time= \frac{Distance}{Speed }

Substitute values for Distance and Speed

Time= \frac{195mi}{50mi/hr}

Time= 3.9hr

The arrival time is:

Arrival = Take\ off + Time\ Taken

Arrival = 3:30pm + 3.9\ hours

Split

Arrival = 3:30pm + 3\ hours + 0.9\ hours

Arrival = 6:30pm + 0.9\ hours

Convert 0.9 hours to minutes

Arrival = 6:30pm + 0.9 * 60\ mins

Arrival = 6:30pm + 54\ mins

Arrival = 7:24pm

What is the solution of the system? Use substitution.
nekit [7.7K]
Substituting y=6x+2 into equation 3y - 18x =12 looks like:

3(6x + 2) - 18x = 12
18x + 6 - 18x = 12  distributive property left side
6 = 12  simplifying the left side

We now see a contradiction:   6 does not equal 12  What this tells us is that there is no solutions to this equation.  So choice 'C' ...

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.
IgorC [24]
B>a 

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>
