Answer:
<h2>58°</h2>
Step-by-step explanation:
We will use the tangent function since we know the opposite and adjacent sides.
Tangent = opposite/adjacent
Tan(e) = 16/10
Tan(e) = 1.6
Use the inverse tangent function to find the angle.
Arctan (1.6) = 57.9946168
Rounding this we get: 58°
Answer:
4
Step-by-step explanation:
-3(4x +3)+4(6x +1)=43
-12x-9 +24x +4 =43
12x - 5=43
12x=43 +5
12x=48
x=48 :12
x=4
Answer:
$63.90
Step-by-step explanation:
First we want to find 10% of 71, this is 7.1.
Since we want to know the price before the tax was added, we will subtract 7.1 from 71 to get our final answer, $63.9
Have a great day ;)
Answer:
Step-by-step explanation:
GIVEN: A bibliophile plans to put a total of seven books on her marble shelf. She can choose these seven books from a mixture of works from Antiquity and works on Post-modernism, of which there are seven each.
TO FIND: If the shelf must contain at least four works from Antiquity, and one on Post-Modernism, then how many ways can he select seven books to go on the shelf.
SOLUTION:
Total number of books available
As there must be at least books on Antiquity and on Post-modernism
Therefore,
when there are Antiquity books and on Post-modernism.
total ways of selection
when there are Antiquity books and on Post-modernism.
total ways of selection
when there are Antiquity books on books on Post-modernism.
total ways of selection
Total ways of selection are
Hence the total ways of selection such that there are at least books on Antiquity and on Post-modernism.
