Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:
, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
Answer:
114.96 pounds at angle 81.76°
Step-by-step explanation:
Let i be the component along x-axis and j be the component along y-axis.
First force that is given is 150 acting at angle 40;
The second force 100 is acting at angle 170;
We now have the resultant force, which is:
Magnitude of resultant:
= 114.96 pounds
Angle it makes with horizontal; inverse tangent of = 81.76 degrees

Answer:
D. 81
Step-by-step explanation:
Raise
3
to the power of
4
.
81
=
x
Rewrite the equation as
x
=
81
.
x
=
81
Each side of the triangle has a little line through them. This means all 3 sides are equal, so all three inside angles would also be equal.
The three inside angles of a triangle need to equal 180 degrees.
Divide 180 by 3 to find the inside angle for each angle:
180 / 3 =60.
Each inside angle needs to be 60 degrees.
Set the equation with x in it to 60 and solve for x:
2x-4 = 60
Add 4 to each side:
2x = 64
Divide both sides by 2:
x = 64/2
x = 32
You multiply the 3 by -6 then multiply the 3 by 6 , one you get -18 and the other you 18x you change the -18 into a positive then add it by 18 in get 36 then you divide by 18x in get 2
