If T and V are complementary angles, their sum is 90°.

   V + T = 90°
   48° + (2X+10)° = 90° . . . . . . . substitute given information
   2X + 58 = 90 . . . . . . . . . . . . .. collect terms
   2X = 32 . . . . . . . . . . . . . . . . .. subtract 58
   X = 16 . . . . . . . . . . . . . . . . . .. divide by 2

The value of X is 16.

An automobile achieves a gas mileage of 30.5 mi/gal. how many kilometers can it travel on 1.5 l of gasoline?
Ksivusya [100]
Gas mileage = 30.5 mi/gal
Volume of gas = 1.5 l 

Note that 1 liter = 0.264172 gallons
Therefore
1.5 l = (1.5 l)*(0.264172 gal/l) = 0.3963 gal

Distance traveled is (Gas mileage, mi/gal)*(Gal of gas)
= (30.5)(0.3963) = 12.087 mi

Answer: 12 mi  (nearest integer)

raketka [301]
This is true. 

When we're talking about the mode, we're usually talking about the number which has the highest frequency in a given set of numbers. For example, out of the numbers:

1 2 3 4 5 6 5 4 5 5 5 

5 will be the mode.
