What does the zigzag line in the circuit diagram represent?A. a source of electrical energy

B. an electrical conductor

C. an electrical resistor

D. an open switch

Answers

The zigzag line in the circuit diagram represents C) an electrical resistor.

the zig zags are resistors, the thing on the left is the symbol for a battery. Sometimes a single cell (1.5V); you'd draw a few more plates to show a higher voltage battery. But a DC supply, anyway. The long line is supposed to be the positive terminal.

Find the length of a rectangular lot with a perimeter of 140 meters if the length is 4 meters more than the width. (P = 2L + 2W)

Answers

The width of the rectangular lot is 33 meters and the length of the rectangular lot is 37 meters.

Let, the width of the rectangular lot is W meters.

According to the problem, the length of the rectangular lot is 4 meters more than the width, so the length would be (W + 4) meters.

Now, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 * Length + 2 * Width

Given that the perimeter is 140 meters, we can set up the equation:

140 = 2 * (W + 4) + 2 * W

Now, solve for W:

140 = 2W + 8 + 2W

Combine like terms:

140 = 4W + 8

Subtract 8 from both sides:

132 = 4W

Finally, divide by 4:

W = 33

So, the width of the rectangular lot is 33 meters.

Now, we can find the length:

Length = Width + 4

Length = 33 + 4

Length = 37

Therefore, the length of the rectangular lot is 37 meters.

the length is 37 and the width is 33 if you add 33+33+37+37 you get 140

What is the x-intercept of the line with the equation 4x + 2y = 12?A. (0, 6)
B. (6, 0)
C. (0, 3)
D. (3, 0)

Answers

x intercept is where the line crosses the x axis or where y=0
set y=0

4x+2(0)=12
4x+0=12
4x=12
divide by 4
x=3

(x,y)
(3,0)

D is answer

Answer:

Option (d) is correct.

The x- intercept of the line with the given equation of 4x + 2y = 12 is (3,0)

Step-by-step explanation:

Given : Equation of line 4x + 2y = 12

We have to find the x- intercept of the line with the given equation of 4x + 2y = 12 and choose the correct option from the given equations.

Consider the given equation 4x + 2y = 12

x intercept is defined as a point where the line cuts y axis that is where point y is 0.

Put y = 0 , we have,

4x + 2(0) = 12

4x = 12

Divide both side by 4, we get,

x = 3

Thus, the x intercept of the line with the given equation of 4x + 2y = 12 is (3,0)

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%. How many total employees does the company now have?

Answers

Answer:

The total number of employees company have now are 531 .

Step-by-step explanation:

As given

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%.

18% is written in the decimal form .

$= (18)/(100)$

= 0.18

Increase in number of employees = 0.18 × Number of employees in company .

= 0.18 × 450

= 81

Total number of employees company have now = Number of employees + Increase in number of employees

= 450 + 81

= 531

Therefore the total number of employees company have now are 531 .

You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:

450(.18)=81

Which you then add:

450+81= 531

So 531 is your total!
