Answer:

7.95

Step-by-step explanation:

In order to solve this, we need to use the rule of sine which is (a/sinA)=(b/sinB)=(c/sinC). Since we have both values of c we can do (12/sin104), which equals ~12.37. Therefore, since we already have A, 12.37=(a/sin40). We can change this by doing sin40×12.37=a. sin40×12.37=7.95.

If Joe drives 186.83 miles on a business trip, and the reimbursement from his company is $13.08. At what rate is Joe's employer

kirill115 [55]

Answer:

7 cents/mile

Step-by-step explanation:

You are looking for a unit rate of cents per mile.

Change the dollar amount to cents, and divide by the number of miles.

$13.08 * (100 cents)/$ = 1308 cents

(1308 cents)/(183 miles) = 7.001 cents/mile

5. Two vertices of a rectangle are (8,-5) and (8,7). If the area of the rectangle is 72 square units, name the possible location

Phantasy [73]

Answer:

<u>Given vertices:</u>

(8, -5) and (8, 7)

These have same x-coordinate, so when connected form a vertical segment.

<u>The length of the segment is:</u>

7 - (-5) = 12 units

The area of the rectangle is 72 square units, so the horizontal segment has the length of:

72/12 = 6 units

<u>Possible location of the remaining vertices (to the left from the given):</u>

(8 - 6, -5) = (2, -5)

and

(8 - 6, 7) = (2, 7)

<u>Similarly to previous exercise:</u>

(5, -8) and (5, 4) given with the area of 48 square units

<u>The distance between the given vertices:</u>

4 - (-8) = 12 units

<u>The other side length is:</u>

48/12 = 4 units

<u>Possible location of the other vertices (to the right from the given):</u>

(5 + 4, -8) = (9, -8)

and

(5 + 4, 4) = (9, 4)
