Determine whether quantities vary directly or inversely and find the constant of variation. 16 factory workers made 40 pieces in

Andrei [34K]

Answer:

Part A) $8\ workers$

Part B) $10\ workers$

Part C) $40\ workers$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

Let

x -----> the number of workers

y ----> the number of pieces made

In this problem

The relation between the variables x and y represent a direct variation (proportional variation)

For x=16, y=40

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

substitute the values

$k=\frac{y}{x}$

$k=\frac{40}{16}\\k=2.5\ \frac{pieces}{worker}$

The linear equation is equal to

$y=2.5x$

Part A) How many workers are needed to make 20 pieces

For y=20 pieces

substitute in the linear equation

$20=2.5x$

$x=8\ workers$

Part B) How many workers are needed to make 25 pieces

For y=25 pieces

substitute in the linear equation

$25=2.5x$

$x=10\ workers$

Part C) How many workers are needed to make 100 pieces

For y=100 pieces

substitute in the linear equation

$100=2.5x$

$x=40\ workers$

Comapre the ratios in table1 and table 2

wariber [46]

Answer:

Step-by-step explanation:

Table 1

3:5 , 6 : 10 , 9 :15 , 12 : 20

Table 2

7 : 10 , 14 : 20 , 21 : 30 , 28 : 40

All table 1 Ratios are equal

All table 2 Ratios are equal

3 : 5

= 6 : 10

6 < 7

=> 6 : 10 < 7 : 10

=> 3 : 5 < 7 : 10

=> The ratio 3:5 is less than the ratio 7:10

All table 1 Ratios are equal

All table 2 Ratios are equal

=> All table 1 Ratios are less than the ratios in Table 2

The ratio 14:20 is greater than the ratio 9:15.
