Answer:

Option D is correct.

Step-by-step explanation:

A plane mirror shows that the image formed by it is of same size as that of object, same distance as that of object and same orientation and laterally inverted.

So, when a point is in IV quadrant and reflection is from Y axis, the image is in III quadrant.

Ninety six passengers rode a train. Tickets for regular coach seats are $114. Tickets for sleeper car seats are $295. The receip

MrRa [10]

C = amount of folks buying coach tickets
s = amount fo folks buying sleeper car tickets

we know the train had a total of 96 passengers, so, whatever "c" and "s" are
c + s = 96

we know all tickets sold for all 96 passengers was 19994, so, if "c" folks rode coach, each ticket is 114, thus 114*c is how much money was from couch, or 114c

if "s" folks rode the sleeper car, we know each ticket is 295 each, so 295*s is how much money was from the sleeper car

we also know, the total for all tickets is 19994

thus 114c + 295s = 19994

thus $\bf \begin{cases}
c+s=96\implies \boxed{s}=96-c\\
114c+295s = 19994\\
----------\\
114c+295\left( \boxed{96-c} \right)=19994
\end{cases}$

solve for "s", to see how many folks rode coach

what about the sleeper car? well, s = 96 - c

M <N=<br>...the scale factor is 2

aivan3 [116]

We know that the sum of the internal angles in each triangle is 180°.

Therefore we have the equation:

$m\angle C+m\angle D+m\angle E=180^o$

substitute and solve:

$79+(6x+11)+(7x-14)=180\\(6x+7x)+(79+11-14)=180\\13x+76=180\ \ \ |-76\\13x=104\ \ \ |:13\\x=8$

We have

$m\angle N=3x+18$

substitute the value of x to the expression:

$m\angle N=3(8)+18=24+18=42$

Answer: m∠N = 42 degrees

Find the area of the shaded region of the circle. Please explain :)

marishachu [46]

Area of shaded part = area of circle - area of the square
= pi (6)^2 - area of the square.

Area of square = (m of one side) ^2
measure of of side is found as follows:-
6^2 = 2s^2 where m of the side = 2s
s = sqrt 18 so side of square = 2 sqrt18
area of square = (2 sqrt18)^2 = 4*18 = 72

area of shaded region = 36pi - 72 = 41.1 sq units to neraest tenth

Given that x is a number there is not negative Kelvin conjectured that x(to the 2nd power) > x+1

Sav [38]

The way this is written, you cannot use -1/2 or -2. Is that correct? Both of them are minus. So the only things you have going for you is 0 and 5

x^2 > x + 1 when x = 5

5^2 > 5 + 1 and his conjecture is true.

25 > 6

==============

What about 0?

0^2 = 0 so

0 > 0 + 1 and the conjecture is false.
