Answer: The voltage across an identical resistor = 60 Volts

Step-by-step explanation:

Step 1

Given  that voltage across the resistor is directly proportional to the current running through the resitor.

 Mathematically, it would be represented as

Voltage  ∝  Current

Introducing the constant of proportionality,  k which represents the Resistor as it is constant.

we have that

Voltage  = K  x  Current

When current = 12 amps and voltage = 480v, the constant of proportionality  K

480 = k x 12

k = 480/12

k= 40

Step 2 ,

when current = 1.5 amps

 Voltage = ?

Using our equation that

Voltage  = K  x  Current

Voltage = 40 x 1.5

Voltage = 60 Volts

Jenny made $315.25 for 8 hours of work. How much would Jenny make for 40 hours of work
bagirrra123 [75]
If Jenny made $315.25 for 8 hours of work:

Then it means that she made:
$312.25/8 hours = $39.41 per hour.

If Jenny works for 40 hours, then she will make:

40 hours × $39.41 = $1,576.25

What is the slope for (2, -1) and (3,1)
ale4655 [162]

Answer: 2

Step-by-step explanation:

m = y2 - y1 /   x2- x1

where slope is m,

so in this case it would be

m= 1-(-1) / 3-2

m=2/1

m=2

Note that you can do it either way

Sally knows the number of hours worked per week for five of the her employees is
steposvetlana [31]

sixth person work per week=47 hours

Average:

The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set

Given :

the number of hours worked per week for five of her employees is

30, 30, 38, 35, and 30.

the average work of 6 employees is  35 hours per week

Solution :

Let, Total work per week= S

sixth person work per week=x

Total work per week= Number of people x average working hour

S= 35(6) = 210..(1)

S = 30+30+38+35+30+x

S= 163+x..(2)

By equation 1 and equation 2

210= 163+x

210-163=x

47=x

sixth person work per week=47 hours

Which statement best explains why the value of this expression is equal to −812y? 414x − 812y − 414x
GarryVolchara [31]
For this case we have the following expression:
 414x - 812y - 414x
 Rewriting we have:
 414x - 414x - 812y
 We group similar terms:
 (414x - 414x) - 812y
 Adding we have:
 0 - 812y
 - 812y
 Answer:
 
The sum of a number and its opposite is 0, and the sum of any number and 0 is the number itself.
