Answer:
82 kg
Step-by-step explanation:
To find the mean of a set of values, we must add them up and divide by the number of values.
Step 1, adding the values:
Step 2, dividing by the # of terms:
There are 9 terms in total.
To the nearest kilogram, we can round 81.556 into 82.
The mean mass of the 9 men was 
kg.

Y = e^tanx - 2
To find at which point it crosses x axis we state that y= 0
e^tanx - 2 = 0
e^tanx = 2
tanx = ln 2
tanx = 0.69314
x = 0.6061
to find slope at that point first we need to find first derivative of funtion y.
y' = (e^tanx)*1/cos^2(x)
now we express x = 0.6061 in y' and we get:
y' = k = 2,9599
let sonia has the (x)
Sandeep would have twice as much as Sonia so (2x)
together they'd have 150.
so, x+2x=150
solve for X
3x=150
X=150/3
So x=50 is what Sonia has,
and Sandeep would have 2(50) =100
Answer:
120 books
Step-by-step explanation:
57 + 3 = 60
60 x 2 = 120
Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180.
We can define angle 3 as x, and angle 4 as (180-x).
x = 3 ( 180 - x ) + 4.
Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.
