Answer:
Explanation below:
Step-by-step explanation:
To solve this problem you have to look at the three measurements (base x length x height), which are 7in, 3in, and 5in. For the top of the rectangular prism, the surface area is 21in (7in x 3in) and since the bottom is the same, the bottom is also 21in. Now that you have the top and bottom, let's look at the sides. The surface area for the long-sides is 35in (7in x 5in) and since both sides are the same, they are both 35. The surface area for the ends of the rectangular prism is 15in (5in x 3in) and since they are both the same, they are both 15in. Now that you have figured out what measurement goes with what, add all them up. (21in +21in) = 42in | (35in +35in) = 70in | (15in + 15in) = 30in
42in + (70in + 30in)
42in + 100in
The surface area for the entire shape is 142 inches.

Answer:
sine A = four-fifths
Step-by-step explanation:
You have a rectangle triangle ABC with hypotenuse AB 35, side CB 28 and side CA 21. The angle C is 90°.
In order to calculate sin A, you take into account that:
The opposite side to angle A is side CB = 28
Hypotenuse = 35
You replace the numeric values of the hypotenuse and side BC in the formula for sinA:
In order to simply the fraction, you divide both numerator and denominator by 7:
hence, the answer is
sine A = four-fifths
Answer:
Step-by-step explanation:
Average salary = ($65,000 + $72,000 + ... + 88,500 )/5 = $77,100
5% of $77,100 = $3,855
15 years * $3,855/year = $57,825
