A plumber charges $60 for a service call, plus $40 per hour for any work completed. Which graph below shows the total amount the
alexdok [17]

using slope intercept equation

\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}

Therefore, the equation is

\begin{gathered} y=60+40x \\ x=\text{hour of work} \\ y=\text{charges in dollars} \\ y=40x+60 \end{gathered}

let us test the x values to know the graph

\begin{gathered} y=40x+60 \\ y=40(1)+60=100 \\ y=40(2)+60=140 \\ y=40(3)+60=180 \\ y=40(4)+60=220 \\ y=40(5)+60=260 \\ y=40(6)+60=300 \end{gathered}

The answer is B

Which expression represents the second partial sum for Infinity Σ 3(1/2) HURRY PLEASE , I need help on a couple of them
nikdorinn [45]

Answer:

Step-by-step explanation:

The given expression has the first term n=1, so exponent = n-1 = 0

Similarly, for the second term n = 2, n-1 = 1

These exponents eliminate options 2 and 4.

Furthermore, the base is a fraction of 1/2, which applies to options 1 and 2 only.

The only viable option left that satisfies all conditions is option 1, which has exponents 0 and 1, with a base of (1/2).

mars1129 [50]
<h3>Hello there!</h3><h3>Answer: 1/13</h3>

1/13 would represent the amount of bananas in the basket.

There would be only 1 banana because it would complete he amount of fruits in the basket.

In the basket, we know that there are:

1 orange + 5 apples + 4 kiwis + 2 pears = 12

That would be 12 fruits, but there are suppose to be 13 fruits, which means that the remaining 1 fruit would be a banana.

So, that means that the amount of bananas in the basket is 1 out of 13, or 1/13.
