Hypotenuse² = perpendicular² + base²

H² = 20²+21²

H²= 400+441 = 841

H = √841

H = 29 cm

Whats the mean for this data? round to 2 decimals places
kolbaska11 [484]

Answer:

1992.38

Step-by-step explanation:

The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.

Sum:

1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56

Divide:

There are 12 numbers, so divide 23908.56 by 12:

23908.56 / 12 = 1992.38

The average is thus 1992.38.

Convert base 10 273 to a base 12
Margaret [11]
The highest power of 12 that divides 273 (with remainder) is 12^2=144, and dividing gives

273=1(144)+129

Divide the remainder term by the next highest power of 12, 12^1=12.

129=10(12)+9

So 273_{10}=1a9_{12}, since

273=1\cdot144+10\cdot12+9\cdot1=1\cdot12^2+10\cdot12^1+9\cdot12^0

A
tatuchka [14]

Alright, lets say the measure of the 3rd angle (the smallest one) is  x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180
