We can find the interior angle (A) that is associated with the angle of depression using the tangent
tan(A) = 970%2F184
A = 79.3 degrees
therefore
90-79.3 = 10.7 degrees is the angle of depression
Answer:
A) 30
Step-by-step explanation:
3*10=30
A 30
Answer:
$19.35
Step-by-step explanation:
129 x .15 = 19.35
1 yard = 3 feet
The foundation is 2/3 yard wide, by 1 yard deep by 10 yards long.
Volume is Length x width x height.
Volume = 2/3 x 1 x 10 = 6.66 cubic yards.
The answer is B.
<u>We are given:</u>
The time-traveller has 79 books, but he can only take 5 books
since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter
Hence, we will use combination
<u>Finding the number of ways:</u>
Since we will use combination, ₇₉C₅
We know that the formula for combination is (n!) / (r!(n-r)!)
₇₉C₅ = 79! / 5!(74!)
₇₉C₅ = 22,537,515
Therefore, the time traveller can choose 5 books in 22,537,515 different ways
