Sanjay consulted three electricians about upgrading the wiring in his home. Each electrician uses a linear formula that incorpor

Reptile [31]

Answer:
b.Each electrician charges a different base fee:

Explanation:
Each of the equations has two parts:
1- base fee that is independent of any variable (this would be the number that has no variable next to it)
2- an hourly rate depending on the number of hours x (this would be the number that has an x next to it)

For the first electrician:
y = 25x + 30
base fee = $30
hourly rate = $25

For the second electrician:
y = 30x + 25
base fee = $25
hourly rate = $30

For the third electrician:
y = 25x + 20
base fee = $20
hourly rate = $25

Now, let's check the choices:
a.Each electrician charges a different hourly rate:
This is incorrect as electricians 1 and 3 charge the same hourly rate ($25)

b.Each electrician charges a different base fee:
This is correct as all three base fees are different ($30, $20 and $25)

c.All three electricians charge the same hourly rate:
This is incorrect as electrician 2 has a different hourly rate

d. All three electricians charge the same base fee:
This is incorrect as the base fees for the three electricians are different ($30, $25 and $20)

Hope this helps :)

The rate to convert yards to meters is

$1 \text{ yard}=0.9144\text{ meters}$

So, if you multiply both sides by 8, you get

$8 \text{ yards} = 8\times 0.9144 = 7.3152 \text{ meters}$

To round the answer to the nearest tenth, we need to choose between 7.3 and 7.4. Since the hundreths digit is 1, which is less than 5, 7.3 is nearest to 7.3152 than 7.4, so the correct answer is 7.3
