Answer:
The easiest way to work out average times is to convert them all to seconds. 60 secs makes 1 min etc. Add all the seconds. Then divide the sum by the number of entries, hope this works.
Step-by-step explanation:
Its looks like there is no question here. Find x maybe?
the shaded part is a right triangle so we can use Pythagorean theorem
c² = a² + b²
c is the longest side of the or hypotenuse
so I can write it as m² + m² = 9²
m² + m² = 81
2m² = 81
/2 /2
m² = 40.5
√ √
m = √40.5 (well its actually = or - but since it really measurement its +)
~ 6.39
since x is to ms its 2 x 6.39
Answer:
x = 11
Step-by-step explanation:
interior angles of a triangle = 180
equation:
⇒ 82 + 31 + 6x + 1 = 180
combine like terms:
⇒ 82 + 31 + 6x + 1 = 180
⇒ 114 + 6x = 180
subtract 114 on both sides:
⇒ 114 - 114 + 6x = 180 - 114
⇒ 6x = 66
divide 6 on both sides:
⇒ 6x = 66
⇒
⇒ x = 11
M is the slope, so, y=mx or y=2x. If y is 8 then x is 4.
y=6 x=r
6÷2=3, so r=3.
hope this helps and sorry if it got confusing.
