Answer: The correct option is B. The point U is the centroid of RST.

Exclamation:

From the given figure it is noticed that the line SU divides the angle S in two equal parts, so the line SU is a part of median line and when the line SU extended until the sideRT is being touched, we get a median line.

The line TU divides the angle T in two equal parts, so the line TU is a part of median line and when the line TU extended until the sideRS is being touched, we get a median line.

The line RU divides the angle R in two equal parts, so the line RU is a part of median line and when the line RU extended until the sideTS is being touched, we get a median line.

The point where the all median of a triangle intersects each other is called centroid.

From the figure we can conclude that all the median of the triangle RST are intersecting on point U, therefore point U is the centroid and option B is correct.

Old faithful in Yellowstone National Park shoots water 60 feet into the air that casts a shadow of 42 feet. What is the height o

Serhud [2]

Answer:

The height of near by tree will be 90 feet.

Step-by-step explanation:

Considering the water triangle as shown in figure a.

As the old faithful shoots water 60 feet into the air that casts a shadow of 42 feet.

Considering the tree triangle as shown in figure a. The tree triangle has a shadow 63 feet long.

Let x be the height of near by tree that cost a shadow 63 feet long.

Assuming that the triangles are similar

So,

the ratios of similar triangles will be related as:

$\frac{63}{42}=\frac{x}{60}$

$\mathrm{Switch\:sides}$

$\frac{x}{60}=\frac{63}{42}$

${x}=60.\frac{63}{42}$

$x=90$ feet

Therefore, the height of near by tree will be 90 feet.

8) If the resistance in an electrical circuit is held constant, the amount of current flowing through the 8) circuit is directly

Len [333]

Answer:

C) 80 milliamperes

Step-by-step explanation:

The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:

$I \propto V\\\\I = \frac{1}{R}V$

Here, $\frac{1}{R}$ is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes( $40 \times 10^{-3}$ amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.
