In the figure, AngleRQS Is-congruent-to AngleQLK. 3 lines are shown. Lines S P and K N are parallel. Line R M intersects line S

P at point Q, and intersects line K N at point L. Angle R Q S is x degrees. Angle K L M is (x minus 36) degrees. What is the value of x?

Answer:

x=108

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠RQS≅m∠QLK -----> by corresponding angles

m∠KLM+m∠QLK=180° -----> by supplementary angles (consecutive interior angles)

we have that

m∠RQS=x° ----> given problem

so

m∠QLX=x°

m∠KLM=(x-36)° ----> given problem

substitute

(x-36)\°+x\°=180\°\\2x=180+36\\2x=216\\x=108

Answer:

108°

Step-by-step explanation:

Angle RQS is congruent to angle QLK. Angle RQS is x degrees, then angle  QLK is x degrees

.

Line RM intersects line KN at point L, then angle KLM, which is (x minus 36) degrees, is complementary to angle QLK. In consequence:

x - 36° + x = 180°

2*x = 180° +36°

x = 216°/2

x = 108°

Which of the following systems of Inequalities would produce the region indicated on the graph below?
Fed [463]
The line rising to the right has equation y = x + 2
and the  other one has equation y =  -x + 4

the lines are solid so the inequalities will be <= or >=

in both case  the shading is below so the sign is <=

also x and Y values are both positive  
so the answer is choice  C

Drainage tubing comes in large rolls. At your hardware store, you cut tubing to the lengths the customers want. You also provide
MrRa [10]

Answer: \frac{1}{36}\pi L

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

V=\pi r^2h

Where "r" is the radius and "h" is the height.

Make the conversion from inches to feet. Since 1\ ft=12\ in,you get:

(2\ in)(\frac{1\ ft}{12\ in})=\frac{1}{6}\ ft

So in this case you  can identify that:

r=\frac{1}{6}\\\\h=L

Then, substituting them into the formula and simplifying you get:

V=\pi(\frac{1}{6})^2L\\\\V=\frac{1}{36}\pi L

Therefore, the expression for the volume of L feet of drainage tubing, in cubic feet is:

\frac{1}{36}\pi L

The graph below shows the air temperature of a location (y), in degrees Celsius, after different time intervals (x), in hours: G
Arisa [49]

Answer:

it is decreasing in the time interval 0<x<2 hours.

Step-by-step explanation:

Graph of first line going through ordered pairs A(0, 40) and B(2, 10).

Graph of second line going through ordered pairs B(2, 10) and C(4, 10). Graph of third line going through ordered pairs C(4, 10) and D(7, 50).

When movement is from point A to B, change in x = 2 and change in y = -30

Hence change for unit x = -30/2 = -15 ... i

When movement is from point B to C, change in x = 2 and change in y = 0

Hence change for unit x = 0/2 = 0 ... ii

When movement is from point C to D, change in x = 3 and change in y = +40

Hence change for unit x = 40/7 = 5.71  .. iii

Hence from A to B it is decreasing, B to C it remains constant and C to D it is increasing.

x coordinate represents hours and y coordinate degrees.

Hence answer is it is decreasing in the time interval 0<x<2 hours.

A sphere has a diameter of 14 ft. Which equation finds the volume of the sphere?
aev [14]

Answer:

The volume of the sphere is 1436 in³

The equation is    

V = ⁴⁄₃ * 3.14 * (7ft)³

Step-by-step explanation:

radius = half of diameter

d = 14ft

r = 14ft / 2 = 7ft

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 7ft

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (7ft)³

V = 4.187 * 343 in³

V = 1436 in³

The volume of the sphere is 1436 in³

As the number of pages in a photo book increases, the price of the book also increases. There is an additional shipping charge o
wlad13 [49]

Answer:

22

Step-by-step explanation:

Solve the inequality  (20 + 0.5x) + 0.15(20 + 0.5x)   ≤ $62.10 for x:

20 + .5x + 3 + 0.75x ≤ 62.10

Combining the x terms, we get:

20 + 3 + 1.25x ≤ 62.10.

Combining the constants on the left:

23 + 1.75x ≤ 62.10

Combining the constants:

1.75x = 39.10

Solving for x:  39.10/1.75 = 22.34

Thus, the max number of whole pages she can have in her book is 22.
