25 meters because 25/20 = 15/12 which is the tangent ratio.
As the question is stated, Tom is standing IN THE TOWER'S SHADOW. If so, then Tom can't cast a shadow of his own, because he is not illuminated. Let's assume the question means to imply that Tom's shadow is measured AT THE SAME TIME that the shadow of the tower is measured, and kind of NEAR the tower, so that the sun casts both shadows from the same place in the sky. If this is a valid assumption, then the tower is 12 meters tall.
The ratios are in the same proportion, so all you need to really figure out is what is in the same ratio to 20 as 6 is to 4.
The x coordinate in the second quadrant is negative while the y coordinate is positive.
I'm not 100% certain I understand what you are asking, but each number in an equation is most generically called a "term," while the actual "+" or "-" symbol is called the "operator".
You cannot. A pound is a measure of mass while a kilogram per second is a measure of flow rate. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
By Similar Triangles. #1 is 15/12 #2 is x /20 Equating 15/12 = x/20 Algebraic rearrangement x = 15 x 20 / 12 x = 300 /12 x = 25 m.

During a full lunar eclipse, the visible half of the moon's surface is in the Earth's shadow while the rest does not receive sunlight because it is facing away from the Sun. Lunar eclipses occur during full moon phases.
Answer is 14 feet
the shadow will famll east
White blood cell casts in the urine are typically associated with acute interstitial nephritis, while red blood cell casts are more commonly seen in acute glomerulonephritis. Pyelonephritis is usually characterized by the presence of white blood cells in the urine without casts.
During a solar eclipse, the moon passes between the Earth and the sun, casting a shadow on the Earth. Areas that are in the path of this shadow will experience the eclipse, while areas outside of the path will not. This creates the variation in visibility of the solar eclipse across different regions on Earth.
The umbra is the darker area of complete shadow, while the penumbra is a lighter area that is only partly shadowed. You can demonstrate this at home. Set up two lamps a couple of feet apart. Hold up a beach ball or sheet of cardboard smaller than the separation, several feet away from the lamps. Each lamp casts light in all directions, and the obstruction casts a shadow - a separate shadow from each lamp. Where both lamps' shadows overlap, this is the umbra. Where one lamp is lighting up the shadowed area from the other lamp, this is the "penumbra".
A solar eclipse happens when the Moon casts two shadows on Earth: the umbra, which is the darkest part of the Moon's shadow, and the penumbra, which is the lighter part. The umbra creates a total eclipse where the Sun is completely blocked, while the penumbra creates a partial eclipse where only part of the Sun is blocked.
Because the Tooth Fairy casts a spell on you.
Birds flying up in the sky do not cast their shadow because the source of light (sun) is too large compared to the object (bird) and the umbra of the shadow formed on the screen (ground) is very small, negligible.So it is tough to see its shadow on the ground.
