Suppose that y is directly proportional to x and that y = 10 when x = 3. Complete parts (a) and (b). (a) Find the constant of pr

Yuliya22 [10]

For this case we have that if "y" varies directly with "x", then it is true that:

$y = kx$

Where:

k: It is the constant of proportionality

We have according to the data that:

$10 = k (3)$

We find the value of "k":

$k = \frac {10} {3}$

Having "k", we find "y" when $x = 6$ :

$y = \frac {10} {3} (6)\\y = \frac {60} {3}\\y = 20$

ANswer:

$k = \frac {10} {3}\\y = 20$

A and B working together complete a work in 35 days. If A takes 60 days to complete it, how long would B alone tale to complete

svp [43]

Answer:

Efficiency (Work done per day) for :

( ˘ ³˘)/

A & B together = 1/35th

A alone = 1/60th

Thus, efficiency of B alone = Total - A’s efficiency

Step-by-step explanation:

OR Efficiency of B alone = (1/35) - (1/60) = 6/210 - 3.5/210 = 2.5/210 = 1/84th

Hence, since B completes 1/84th work daily, he would take 84 days to complete the work alone.
