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

$100=2.5x$

$x=40\ workers$

Solve for x:<br><br> -x/3 = 2

Dima020 [189]

Answer:

x = -6

Step-by-step explanation:

-x/3 = 2

Multiply each side by -3 to isolate x

-x/3 * -3= 2*-3

x = -6

Answer:

In a representation of 100, the percent change is just a number change, meaning 65 - 52, or 13 is that change. This means that the percent change from 65 to 52 is 13%

Find the measure of each angle.<br><br><br>If m∠EBC = 55° and m∠EBD = 20°, find m∠2

weeeeeb [17]

Using the angle addition theorem, the measure of angle 2 in the given diagram is: m∠2 = 35°

<h3>What is the Angle Addition Theorem?</h3>

Based on the angle addition theorem, the sum of two smaller angles that make up a bigger angle equals the sum of the bigger angle.

Given the following:

m∠EBC = 55°
m∠EBD = 20°

m∠EBC = m∠EBD + m∠2 [angle addition theorem]

Substitute

55 = 20 + m∠2

m∠2 = 55 - 20

m∠2 = 35°
