A line segment from a vertex to the midpoint of the opposite side is a "median". A median divides the area of the triangle in half, as it divides the base in half without changing the altitude.
AAMC is half AABC. AADC is half AAMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
ABMC is half AABC. ABMD is half ABMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
Then, AADC = 1/4 AABC = ABMC, so AADC = ABMC by the transitive property of equality.

So the first hour it travels from 1-6 miles, the second hour it travels at least two miles. And the question is "draw the range of miles the boat could of traveled in the second hour". Well first of all the third hour is completely useless so forget about that. Now, the first hour says it traveled from 1-6 miles, we don't know how many miles it traveled for sure but it could of traveled up to 6. So in the second hour when they say "at least two miles" the boat could of travled at least two miles more than 1-6. So 1+2+3, 2+2+4, 3+2=5, 4+2=6, 5+2=7 and 6+2=8. So the boat could of traveled from 3 to 8 miles in the second hour.

Which set has the same mean, median, and mode?
Scilla [17]

Answer:

A.

Step-by-step explanation:

Sets  A and C have a mode of 12 and a median of 12.

Calculate the means:

Set A:   Mean = (8+10+12+12+14+16 )  /  6 =  12

Set C:   Mean = (6 + 6 +12+12+18+24 ) /  6 =  13

So the required  set is A.

Answer:

\cot \theta =  \frac{8}{15} \\\\\sec \theta =  \frac{17}{8} \\\\\csc \theta =  \frac{17}{15}

Step-by-step explanation:

\huge \tan \theta =  \frac{15}{8} ...(given) \\  \\  \huge \because \:  \cot \theta =  \frac{1}{ \tan \theta} \\  \\  \huge \therefore \: \cot \theta =  \frac{1}{ \frac{18}{8} } \\  \\  \huge \therefore \:  \cot \theta =  \frac{8}{15}  \\  \\ also \\ \huge  \sec \theta =  \frac{17}{8}  \\
