Find the exact value of tan θ.

Mathematics
1 answer:
FrozenT [24]3 years ago
5 0

Answer:

The answer is C.

Step-by-step explanation:

Recall SohCahToa, where tan(\theta)=opp/adj.

In the triangle, the opposite (to angle theta) is 6, while the adjacent is 2\sqrt{5}.

Put this into the equation:

tan(\theta)=\frac{6}{2\sqrt5}

Now, simplify: (multiply both top and bottom by \sqrt5

\frac{6}{2\sqrt{5} } \cdot\frac{\sqrt{5} }{\sqrt{5}} =\frac{6\sqrt{5}}{2(5)} =\frac{6\sqrt{5}}{10}=\frac{3\sqrt{5} }{5}

The answer is C.

Tema [17]
Given:
The train has 6 passenger cars
Each car has 4 columns
And 1 column hold 50 passengers

So, total of seats will be = 6 * 4 * 50 = 1200

Now, there are 25 empty seats, 

therefore the correct equation will be : 

Number of seats per car: 4 × 50 = 200

Total number of seats: 200 × 6 = 1,200

Number of passengers: 1,200 − 25 = p

The cost of a stove to a store owner was $500, and she sold the stove for $1080. What was her percent of profit based on cost?
Juliette [100K]

Answer:

116%

Step-by-step explanation:

Cost Price (C. P.) = $500

Selling Price (S. P.) = $1080

Profit = SP - CP = $1080 - $500 = $580

Profit percent

=  \frac{Profit}{CP}  \times 100 \\  \\  =  \frac{580}{500}  \times 100 \\  \\  =  \frac{580}{5}  \\  \\  = 116 \%

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed.
LenaWriter [7]

Answer:

28 meters cubed.

Step-by-step explanation:

Since we know that the volume of a sphere is 4/3 the volume of a cylinder, we can multiply 21*4/3. 21*4 will equal 84 and 84/3 would be 28. So the volume of the sphere would be 28 meters cubed.
