Without using a calculator how do you evaluate tan 5π/6.
Mama L [17]
Remember that pi=180, 
so 180/6=30, 30*5=150,
what's tan 150? 
Remember that 150 degrees is in the 2nd quadrant, and this is tangent, so it means the answer must be negative, because tan 150= - tan 30, and -tan30=-√3/3. 

Answer: -√3/3.

Anyone care to help? :)
Elan Coil [88]
So when you factor this the answer would be (1w - 3)(5w + 1) because since 5 is an odd number you have to break it up with us only factores then you find the GCF for 3 and then you have to find the signs that when you multiply them it gives you - 14

The weather satellite shows that hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilome
jenyasd209 [6]

Answer:

1. 3 days.  

Step-by-step explanation:              

We have been given that the hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilometers per hour.

First of all we will find the number of hours it will take for George to reach Puerto Rico. We can find number of hours taken by hurricane George to reach Puerto Rico by dividing 1728 by 24.

\text{Time}=\frac{\text{ Distance}}{\text{ Speed}}

\text{Time taken by hurricane George to reach Puerto Rico}=\frac{1728}{24}

\text{Time taken by hurricane George to reach Puerto Rico}=72

We can see that George will reach Puerto Rico in 72 hours. Let us convert hours to days by dividing 72 by 24 (number of hours in a day).

\text{Days taken by hurricane George to reach Puerto Rico}=\frac{72}{24}=3

Therefore, the hurricane George will reach to Puerto Rico in 3 days, if the hurricane stays on its present course. Our first option is the correct choice.

A car traveled at an average rate of 51 miles per hour on one highway. It then traveled at an average rate of 71 miles per hour
sergiy2304 [10]

d1 = 51(t)

d2 = 71(8 - t)

d1 + d2 = 508

and now you just have to solve for t.
