Answer:

Answer:

11.47

Solution,

Fromthe figure,

cos \: 55 = (</strong><strong>PQ</strong><strong>)/(</strong><strong>PR</strong><strong>)

cos \: 55 = (</strong><strong>PQ</strong><strong>)/(20)

</strong><strong>PQ</strong><strong> = 20 \: cos \: 55

</strong><strong>PQ</strong><strong>= 11.472

</strong><strong>PQ</strong><strong>= 11 .47

Hopethis helps...

Goodluck on your assignment...
Answer 2
Answer:

Answer:

11.47

Step-by-step explanation:

Use SohCahToa. In this problem, you are given the hypotenuse and you are trying to solve for the adjacent side so it will be cosine. (cosine = (adjacent)/(hypotenuse))

1. set up the equation

cos55 = (x)/(20)

2. Multiply both sides by 20 to solve for x

20 · cos55 = 11.47

B.Trail X has a positive slope (it runs uphill). 
C.Trail X has a negative slope (it runs downhill). 
D.Trail Y is steeper than trail X.

So because trail Y has a negative slope, and X is perpendicular to Y the X has a positive slope. \ <---- neg slope y and / <----- pos slope x

Car rental company A charges $45 a day to rent a certain car. Car rental B charges $30 a day plus $0.20 per mile to rent a similar car. For how many miles is the cost at car rental Company B more than the cost at car rental company A?​

Answers

Answer is given below

Final answer:

The cost at car rental company B is more than the cost at car rental company A when the number of miles driven is greater than $15.

Explanation:

The cost at car rental company B is more than the cost at car rental company A when the number of miles driven is greater than $15.

To find this, you can set up an equation:

  • The cost at car rental company A is given by: $45 x d, where d represents the number of days.
  • The cost at car rental company B is given by: ($30 + $0.20m) x d, where m represents the number of miles driven.

So we need to find when ($30 + $0.20m) x d is greater than $45 x d.

($30 + $0.20m) x d > $45 x d

$30 + $0.20m > $45

$0.20m > $15

m > 75

Therefore, when the number of miles driven exceeds 75, the cost at car rental company B is more expensive.

22% of 320 = n
22% × 320 = n
0.22 × 320 = n
(22% = (22)/(100) = 0.22)
70.4 = n 

22% of 320 = 70.5

Answer is B. 70.4
