Two parallel lines are crossed by a transversal. What is the value of k? k = 9 k = 20 k = 60 k = 71
Musya8 [376]

your question seems missing the figure.

I am attaching the required figure below.

You can study the correct answer to your question and complete explanation with the figure  below.

Answer:

k=60

Step-by-step explanation:

When a pair of parallel lines is crossed by a transversal, it will make 8 angles, pairs of vertical/opposite angles, two pairs of acute angles and two pairs of obtuse angles. All acute angles are congruent as well as all obtuse angles are congruent. Simply we can say that pairs of acute angles and pairs of obtuse angles are congruent.  

From the figure attached below (by the name "Pairs of parallel lines crossed by a transversal"), we get the following equations as:

2k+11=131

Solving for k, we get

2k=131-11

2k=120

k=120/2

k=60

You are borrowing $4,000 to purchase a HD plasma TV using a 36 month installment plan. Determine the annual percentage rate (APR
LekaFEV [45]
Annual Percentage rate (APR) is calculated by the formula:

APR = 72i / {3P(n+1) + i(n-1)}

where:

i = Interest Rate
P = principal amount borrowed
n = number of months of the loan

Given: 

Interest rate = $782.96
Principal amount = $4,000
number of months = 36 months

Substitute the given to the formula:

APR = 72(782.96) / [{3(4000)(36+1)} +  {782.96(36-1)}]
APR = 56,373.12 / {444,000 + 27,403.60}
APR = 56,373.12 / 471,403.60
APR = .1196 X 100    ⇒ Multiply by 100 to get the percentage
APR = 11.96% or 12%  (c)

the legs of a right triangle are 10 centimeters and 24 centimeters long. what is the length of the hypotenuse?
igomit [66]
Pytharorean therum...can only be used on right triangles
a^2 + b^2 = c^2...a and b r ur legs and c is ur hypotenuse
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
sqrt 676 = c
26 = c <== ur hypotenuse is 26 cm

Tres hermanos van a repartirse un pastel y medio, cuanto le toco de pastel a cada uno de los hermnos
Anna71 [15]

Answer:

medio pastel cada uno

Step-by-step explanation:

Hay 3 hermanos, si decimos que un pastel entero tiene 6 pedazos entonces su fraccion seria 6/6. Si dividimos este pastel entre los tres hermanos cada uno tendria...

\frac{6 / 3}{6} = \frac{2}{6}

Medio pastel seria la mitad de 6/6 que seria 3/6. Si dividimos esto entre los 3 hermanos cada uno tendria...

\frac{3 / 3}{6}  = \frac{1}{6}

Ahora que dividimos los 2 pasteles tenemos que unir las fracciones para saber cuanto pastel le toco a cada hermano...

\frac{2}{6} + \frac{1}{6} = \frac{3}{6}  o medio pastel cada uno
