40+90=130
180-130=50
50+130=180
x=130
50+x=180
2/5+3/8= 31/40 therefore he still has 9/40 to go.
to get this you multiply the two denominators together
5x8=40 which is your denominator
then you cross multiply the two numerators
2x8=16
3x5=15
to get the final
15/40+16/40=31/40
and you are left with 9/40
Answer:

Explanation:
To find the inverse of a function expressed as
XXX
y
=
an expression in
x
rearrange the expression into the form:
XXX
x
=
an expression in
y
Given
XXX
y
=
3
x
2
−
5
Switch sides and add
5
to both sides
XXX
3
x
2
=
y
+
5
Divide both sides by
3
XXX
x
2
=
y
+
5
3
Take the square root of both sides
XXX
x
=
±
√
y
+
5

Since we were asked for an inverse function, I've eliminated the non-primary root (a function can not have two values for a single argument value).
Therefore
XXX
x
=
instead of Y do G
Step-by-step explanation:
Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.
