The label on a ceiling lighting fixture warns you to use a lightbulb of 60 watts or less. The voltage to the lightbulb is 120 vo
patriot [66]

Answer:

0.5 A

Step-by-step explanation:

Hi,

I believe the question is incomplete. However, as per the information provided:

The simplest way to calculate the Current (unit is Amperage), is understanding the relationship between the three: Power, Voltage and Current.

<em>(Quick Tip: </em><em>W=AV</em><em>; where W -> Watts (Power), A -> Ampere (Current), V -> Volts (Voltage))</em>

Using the formula we calculate the Ampere:

W = A x V

60 = A x 120

60/120 = A (We divide the equation be 120)

0.5 = A  (Simply reduce the fraction 60/120  = 1/2 = 0.5)

Why might the triangulation method not always produce an exact point (other than any measurement errors)
Rufina [12.5K]

Answer:

The triangulation method might not always produce an exact point (other than any measurement errors) because:

The method uses different data sources, researchers, and theories or perspectives.

Step-by-step explanation:

Research Triangulation uses multiple methods, data sources, different investigators, and varied theories for the purpose of developing a more comprehensive understanding of the underlying situations.  Triangulation validates the qualitative research by obtaining information from different sources, investigators, viewpoints, or methods.

Nataly [62]

1 cup=8 ounces

5*8=40

Each day the women drinks 40 oz of coffee.

40oz-75%=10oz

Thus, if the women complies to the physician's instructions, she can drink 10oz or about 1.25 cups of coffee daily.

If ED = 5y + 6 and DB = y + 30, find the value of y. Then find ED, DB, and EB.
Gemiola [76]

Answer:

Part 1) The value of y=6

Part 2) ED=36, DB=36 and EB=72

Step-by-step explanation:

In this problem we know that

ED=DB -----> equation A

EB=ED+DB -----> equation B

The point D is the midpoint ED

see the attached figure to better understand the problem

step 1

Find the value of y

Substitute the given values in the equation A

5y+6=y+30

solve for y

5y-y=30-6

4y=24

y=6

step 2

Find the value of ED,DB and EB

ED=5y+6

substitute the value of y

ED=5(6)+6=36

Remember that

ED=DB

therefore

DB=36

Find the value of EB

EB=ED+DB

EB=36+36=72
