A mountain climber on Mount Everest is at 29,035 feet above sea level a stone at the bottom of the sea is at 1,349 ft below sea

slavikrds [6]

30,384 feet difference between the two, since the climber is 29,035 feet above sea level you take a positive 29,035 and a -1,349 due to being below sea level, you add the two together with the equation 29,035+1349=30,384 feet

A service station checks Mr. Smith's radiator and finds it contains only 40% antifreeze. If the radiator holds 20 quarts and is

storchak [24]

Answer:

8 quarts

Step-by-step explanation:

Step One: Figure out how much 40% is by making an equation:

Since we are looking for a percentage, we use cross multiplication to find X.

$\frac{x}{20} = \frac{40}{100}$

Step Two: multiply 20 by 40 to start cross multiplying:

20 times 40 is 800, so replace the 40 by 800 in the equation.

$\frac{x}{20} = \frac{800}{100}$

Step Three: divide 800 by 100, and we will have X:

800/100=8

X=8 aka 8 quarts

dezoksy [38]

Answer:

cscθ = $\frac{1}{y}$

Step-by-step explanation:

cscθ = $\frac{Hypotenuse}{opposite}$

For a unit circle, radius = 1

hence, hypotenuse = 1

opposite = y

cscθ = $\frac{1}{y}$
