Answer:
1.922 miles is equivalent to 3.1 kilometers.
Step-by-step explanation:
Given:
1 km = 0.62 miles.
3.1 km = ? miles
Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.
From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.
So, conversion factor = 
The formula to transform 'n' kilometers to miles is given as:
Therefore, 3.1 km = 
3.1 km =
miles
Therefore, 1.922 miles is equivalent to 3.1 kilometers.
We can use the Сosine formula to solve this problem.
<span>First we must find the third side (АС) of the triangle:
</span>

<span>
The smallest angle of the triangle lies opposite the smallest side, so we need to find m</span>∠C.

Now we can use Bradis's Table (I don't know the name in English, maybe Trigonometric Table?) to find m∠C:
m∠С = 38°42' = 38.7°
Answer: 38.7°

Answer:
Q1: p = - 33
Q2: d = - 99
Q3: t = - 13
Step-by-step explanation:
Q1: 
We solve this taking LCM.
We get: 


Q4: 
Again we proceed like Q1 by taking LCM.
We get: 



Q7: 5t + 12 = 4t - 1
We club the like terms on either side.



Hence, the answer.
Answer:
Find the area of the base of the cylinder using A = (pi)r 2 . Subtract your answer from the 80 square inches for the cube and the area of the cylinder. 4. Add the surface areas of each figure to get the total area of the composite figures.
