<h3>Answer:  k = 10</h3>

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

Work Shown:

Use the remote interior angle theorem.

The interior angles (4k+5) and (6k+10) add to the exterior angle 115. Note the interior angles are not adjacent to the exterior angle. This is where the "remote" aspect comes in.

So,

(4k+5) + (6k+10) = 115

10k + 15 = 115

10k = 115 - 15

10k = 100

k = 100/10

k = 10

We can stop here.

If you want to keep going, then,

4k+5 = 4*10+5 = 45

6k+10 = 6*10+10 = 70

Note how 45+70 = 115 to help confirm our answer.

A computer randomly generates a 5-digit string using numbers between 0 and 9 inclusive. What is the probability that the first t
garik1379 [7]

Answer: 0.01.

Step-by-step explanation:

Given: A computer randomly generates a 5-digit string using numbers between 0 and 9 inclusive.

i.e. each place in 5 digit number has 10 choices.

Total ways to make such a number = 10^5=100000.

If the first two digits in the string are a 4 and a 2, in that order, then the number of ays to make this kind of number = 1 x 1 x 10 x 10 x 10 = 1000  [as 4 and 2 can be put on first and second place in 1 way ]

Now, the probability that the first two digits in the string are a 4 and a 2 , in that order = \dfrac{1000}{100000}=\dfrac{1}{100}=0.01

Hence, the probability that the first two digits in the string are a 4 and a 2 , in that order = 0.01.

(secA+cosA)(secA-cosA)=tan^2A+sin^2A
vlabodo [156]

(\sec A+\cos A)(\sec A-\cos A)=\sec^2A-\cos^2A

\sec^2A-\cos^2A=(1+\tan^2A)-(1-\sin^2A)

(1+\tan^2A)-(1-\sin^2A)=\tan^2A+\sin^2A

Anon25 [30]
You didn't include the options, so whichever one looks like x=(12.53+11.86)3.19 or something similar. You need to add the amount of gallons he bought, then multiply them by the cost per gallon, which will most likely be set equal to a variable.
