Answer: B: each electrician charges a different base fee
Step-by-step explanation:
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)

Answer:
x + 7 = 14 // x - 5 = 2 // x - 9 = -2 // 3x - 15 = 6 … (x = 7)
2x - 1 = 7 // 2x - 5 = 3 … (x = 4)
2x - 3 = 3 // 2x + 5 = 11 // 4x + 2 = 14 // 2x + 1 = 7 … (x = 3)
12x - 3 = 24 // 4x - 1 = 8 … (x = 9/4)

A circle is translated 4 units to the right and then reflected over the x-axis. Complete the statement so that it will always be true of the circle at the new location.
The circle at the new location has the original circle.
the same center as
twice the circumference of
half the radius of
the same area as
Options
The circle at the new location has _____________ the original circle.
- the same center as
- twice the circumference of
- half the radius of
- the same area as
Answer:
the same area as
Step-by-step explanation:
When a circle is translated and reflected, the center of the circle will change; however, its area, circumference, radius and diameter remain the same.
This is so because, translation and reflection only affect the positioning of the circle not the size.
Considering the above analysis, we can conclude that option d answers the question correctly.
Answer:

Which sum does the model below represent?
4 positive tiles and 7 negative tiles.
4 + (negative 7) = negative 3
4 + 7 = 11
8 + (negative 3) = 4
11 + (negative 4) = negative 3
The sum the model below represents will be 4 + (negative 7) = negative 3. Option A is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, the expression is 4 positive tiles and 7 negative tiles. We have to apply summation for the given expression,
Expression is the combination of constants and variables with mathematical operators.
The model is algebraically solved as,
=4+(-7)
= -3
Thus, the sum the model below represents will be 4 + (negative 7) = negative 3. Option A is correct.

PLS!!! HELP ME I WILL MARK U!!!
Answer:
Step-by-step explanation:
23.37
Answer:
-32.27
Step-by-step explanation:
[tex]n^{2}p +p[/tex]
First you have to substitute the values. (n = -1.9 and p = -7).
Substituting it would get to [tex](-1.9)^{2}(-7) + (-7)[/tex].
First you solve the exponent which would get it to [tex](3.61)(-7) + (-7)[/tex].
Then you would multiply to get it to -25.27 - 7.
That gets to -32.27.

how do I find angle k?
Answer:
I believe (not confident) You take 180-28 and divide that by 2. (76 degrees)
We know that the top angle of the triangle is 28 degrees because vertical angles are congruent.
Step-by-step explanation:
Answer:
i think ?? CORRECT ME IF IM WRONG -check my user
Step-by-step explanation:
do an opposite angle to get the top of the left triangle so it will be 28
180-28=152
152÷2=76 (because its an isosceles)

During a snowstorm, Eva tracked the amount on the ground. When the storm being, there was no snow on the ground. Snow feel at a constant rate of 3 inches per hour until 6 inches had fallen. The storm then stopped for 5 hours and then started again at a constant rate of 2 inches per hour for the next 2 hours. As soon as the storm stopped again the sun came out and melted the snow for the next 2 hours at a constant rate of 4 inches per hours
Answer:
2 inches of snow was left on the ground
Step-by-step explanation:
To calculate the amount of snow on the ground we can take it one step at a time. Since there was no snow on the ground we can start at a level of 0. Then it snowed until 6 inches of snow had fallen, so we can add that to our total.
0 + 6 = 6 inches
Next, it snowed for 2 more hours at a rate of 2 inches per hour, meaning we multiply this by 2 hours and add to the total amount of snow that was already on the ground.
(2*2) + 6 = 10 inches
Lastly, the sun came out and melted the snow on the ground for 2 hours at a rate of 4 inches per hour. Since it is melting the snow, this means that it is subtracting the snow from the total. So we would have to multiply the rate (4 inches per hour) by the number of hours and then subtract that from the amount of snow on the ground.
10 - (4*2) = 2 inches
