You need to calculate 35% of 400.
The way I do this on paper is I split it up into chunks and then add the chunks together.
First I would calculate 10%. To do this, divide 400 by 10, because to get from 100% to 10% you must divide by 10.
So 10% = 40
You need 30%, so you just multiply by 3, because to get from 10% to 30%, you multiply by 3.
So 30% = 120
5% is half of 10% so half of 40 is 20.
So 5% = 20
30% + 5% = 35%
120 + 20 = 140

Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)

Answer:
8.7
Step-by-step explanation:
We have the side adjacent to the angle and we want the hypotenuse. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
Solving for the hypotenuse, we find ...
VW = XW/cos(36°) = 7/0.80901
VW ≈ 8.7
