Answer:
It is not direct variation
Step-by-step explanation:
y/7 = 2/x
y = 7×2/x
y = 14/x
And
y = k/x
k = 14 which is the constant of proportionality
: y ∞ 1/x
This is inverse variation
Answer:
184cm^2
Step-by-step explanation:
(5+5+6) * 10 = 160
6*4 = 24
160+24=184
there are 2 triangles so I am assuming they have the same dimensions

Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° =
, thus
sin60° =
=
=
( cross- multiply )
x ×
= 8
( divide both sides by
)
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° =
, thus
tan60° =
=
=
( multiply both sides by y )
4
= y ×
( divide both sides by
)
y = 4
8/10<span> is usually written 4/5, so yes it is irrational. </span>
