180-72=108. y=108. (same side interior angles are supplementary , must add up to 180).
Elena L [17]3 years ago
3 0
This is a same side interior angle, which means that the two angles, when added, will equal 180°

y + 72 = 180

Isolate the y, subtract 72 from both sides

y + 72 (-72) = 180 (-72)

y = 180 - 72

y = 108

A) 108°, is your answer

Find the limit of the function by using direct substitution as X approaches one lim(x^2-8x -2)
Leno4ka [110]

Answer:

lim_{x \to 1} x^2 -8x -2 =-9

Step-by-step explanation:

For this case we want to find the following limit:

lim_{x \to 1} x^2 -8x -2

And we can find the limit distirbuting into each term like this:

\lim_{x \to 1} x^2 -8 lim_{x \to 1} x -lim_{x \to 1} 2

And replacing we got:

1^2 - 8*1 -2 = 1-8-2 = -9

So then the final answer for this case is:

lim_{x \to 1} x^2 -8x -2 =-9

An average of 40 cars per hour arrive to be painted at a single-server GM painting facility. 95% of the cars require 1 minute to
Sindrei [870]

Answer:

2.719 minutes

Step-by-step explanation:

Step 1 :

We have to consider using the M/G/I /GD /∞/∞ Queuing system with the rate of arrival λ and the rate of service μ.

Since average of 40 cars arrive every hour at the painting facility, it follows that:

Arrival rate λ = 40cars /hour

= 40/60 cars/hour

=2/3 cars/hour

More, we were told that 95% of the cars require 1 minute to paint, 5% must be painted twice and require 2.5 minutes to paint, therefore, the average time to paint a car is given by

95/100x1 + 5/100 x 2.5 = 19/20 + 1/8 = 43/40min

It follows that:

Service rates μ = 40/43cars/min

Find two consecutive even integers such that the square of the second, decreased by twice the first is 52
Fiesta28 [93]

Let the first integer be x. So, the next even number is x+2

Let's translate the formula: the square of the second is (x+2)^2, twice the first is 2x. So, the equation is

(x+2)^2 - 2x = 52

Expand the square to get

x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0

The solutions to this equations are

x = -8,\quad x = 6

So, the possible consecutive even numbers are

-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8
