Math - Use unit conversion factor to convert the units.

nlexa [21]

Answer: 240 minutes, 20 cups, 4000 pounds

Step-by-step explanation:

Use the following conversions:

1 hour = 60 minutes

2 cups = 1 pint

2 pints = 1 quart

1 ton = 2000 pounds

$4\ hours\times \dfrac{60\ minutes}{1\ hour}=\large\boxed{240\ minutes}\\\\\\\\5\ quarts \times \dfrac{2\ pints}{1\ quart}\times \dfrac{2\ cups}{1\ pint}=\large\boxed{20\ cups}\\\\\\\\2\ tons\times \dfrac{2000\ pounds}{1\ ton}=\large\boxed{4000\ pounds}$

Prove: cos(3x)=sin(2x)

Vesnalui [34]

Answer:

Step-by-step explanation:

Step-by-step explanation:

By taking ( x = 18°)

L.H.S

cos(3x)=sin(2x)

cos(3x) = cos( 3X18°)= cos (54°)

= cos[ 90° - (2x18°)] ∵[ 90°- (2x18°) = 54°]

= ∴ sin ( 2x18°)

As (x = 18°)

= sin (2x) = R.H.S
