Answer:
Step-by-step explanation:
So when x and y, vary inversely, it means that the product of x and y will remain constant such that: . This means that the function can be defined as by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation: , which can be defined as
Answer:
see explanation
Step-by-step explanation:
Using the cosine and tangent ratios in the right triangle
cos41° = = =
Multiply both sides by VX
VX × cos41° = 7 ( divide both sides by cos41° )
VX = ≈ 9.3
-----------------------------------------------------------------------
tan41° = = =
Multiply both sides by 7
7 × tan41° = WX, thus
WX ≈ 6.1
-------------------------------------------------------------------------
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for ∠ X
∠ X = 180° - (90 + 41)° = 180° - 131° = 49°
Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now
now=182
percent means parts out of 100 so
130%=130/100=13/10
182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140
