Answer:

Step-by-step explanation:

Use PEDMAS

(3 + 4) - 4/42 + 3(4 +2)/3 = 7 - \frac{4}{42} + 3 * \frac{6}{3}      {Inside parenthesis}

                                        = 7 - \frac{2}{21} + 6     {Division}

                                        = 13 - \frac{2}{21}

                                        =\frac{13*21}{1*21}-\frac{2}{21}\\\\=\frac{273}{21}-\frac{2}{21}\\\\=\frac{271}{21}

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is -6?
babymother [125]

Answer:

Line M - neither

Line N - parallel

Line P - perpendicular

Line Q - neither

Step-by-step explanation:

If a line is perpendicular to another, the slope will be the opposite, e.g. -6, opposite slope, -6.

If a line is parallel to another, the slope will be the exact same, e.g. -6, same slope, 1/6.

HELP!!!! 60 POINTS to whoever does this (geometry proof)
ASHA 777 [7]

Answer:

A) This is correct. The angles of <em>AEB </em>are the angles of <em>DEC. </em>This means that this is true.

B) This is incorrect. This triangle is NOT an isosceles triangle. The angles of an isosceles triangle are supposed to be about 36° for the top angle, and 72° for the other two angles. (At least this is what I was told)

Hope this helps :)

-wait. .___. they both might be true.

According to G oogle: "All the three angles situated within the isosceles triangle are acute, which signifies that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known."

Problem:
BARSIC [14]

Answer:

(c) Equation  which can be used to find r, the cost in dollars to park s nights is  r = 24.99 s

Step-by-step explanation:

Here, the parking cost of 1 night at the airport  = $24.99

Now, here the total number of nights the car is parked at airport = s

R = The total cost of parking s nights

Now, The cost for parking s nights  = s x ( Cost of parking 1 night)

= s x ($24.99) = 24.99 s

Also the cost for parking s nights    = r

⇒  r = 24.99 s

Hence, equation  which can be used to find r, the cost in dollars to park s nights is  r = 24.99 s
