If y varies inversely with x and y=2 when x=5, what is the value of x when y=3?

Answer:

Step-by-step explanation:

Method

Inversely in this sentence means

y = k/x    

So you first step is to find the value of k. You do that by setting up an inverse relationship with y = 2 , x = 5

2 = k/5                     Multiply both sides by 5

2*5 = 5*k/5

10 = k

Now you are able to answer the question.

  • k = 10
  • y = 3
  • x = ?

y = 10/x

3= 10/x                      Multiply both sides by x

3*x = x * 10/x

3x = 10                      Divide both sides by 3

3x/3 = 10/3

x = 3.33 or x = 3 1/3

Answer

x = 3.33 or x = 3  1/3

type the correct answer in the box. if the measure of angle θis 7⁢π6. the equivalent measurement in degrees is °.
Travka [436]

If the measure of an angle "θ" is 7⁢(π/6), then it's equivalent measurement in degrees is 210°.

As per question statement, we have an angle "θ" whose measurement in radians is 7⁢(π/6). We have to convert this radians into its equivalent measurement in degrees. Thus, to solve this question, we will have need to know the relation between radians and degrees, which goes as,

("π" Radian = 180°).

Then, we will apply unitary method to our provided data and use the above-mentioned relation to obtain our desired answer, i.e.,

π Radian = 180°,

then, 7π Radian = (180*7)°,

Then, 7⁢(π/6) Radian = \frac{(180*7)}{6} =(30*7)=210°.

  • Radian: This is an unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
  • Degrees: This is another unit of measurement of angles, one unit of this being equal to one three-hundred-and-sixtieth of the circumference of a circle.
