Answer:

At the time measurement starts i.e. initially there was no rainfall i.e. y value is zero.

Step-by-step explanation:

y, in terms of time the rain fell, x.

Now, x is measured in hours after 12 : 00 P.M., with x = 0 corresponding to the time 12 : 00 P.M.

Therefore, the ordered pair (x,y) ≡ (0,0) means that at the time measurement starts i.e. at 12 : 00 P. M. there was no rainfall i.e. y value is zero. (Answer)

A band consists of 3 woodwinds for every 7 members of the band. The independent quantity represents the total members of the ban
IgorC [24]

Answer: k=\frac{3}{7}

Step-by-step explanation:

For this exercise it is important to remember the following:

The constant of proportionality, which is represented as "k", describe  the constant ratio of two quantities that are proportional (the independent and dependent variables).

In this case we know that the independent quantity represents the total members of the band and the dependent quantity represents the woodwind members of the band.

Since the band consists of 3 woodwinds for every 7 members of the band, we can conclude that the constant of  proportionality for this relationship is:

k=\frac{3}{7}

3/5 (10x + 15) = +30 help me please
sergeinik [125]

Answer:

x = 3.5

Step-by-step explanation:

\frac{3}{5} (10x + 15) = 30

10x + 15  = 30 * \frac{5}{3}  

10x + 15   = 10 * 5

10x + 15   = 50           {Subtract 15 form both sides}

         10x = 50 -15

        10x = 35         {Divide both sides bt 10}

    10x/10 = 35/10  

          x = 3.5
