Answer:

Duff has 2 sandwiches and 3 bags of chips. Duff's total cost would be $18.5

Step-by-step explanation:

We know that chips cost $1 per bag. We also know that sandwiches cost (s). It shows that there is 2s, therefore being two sandwiches and 3 chip bags. Duff's total cost would be $18.5. It's because if sandwiches cost $7.75, and he has two, we multiply it by x2. The answer to that, would be $15.5. We also know that he has 3 bag of chips, therefore adding $3. So in total, Duff's total is $18.5.

Find the distance between each pair of points. Round your answer to the nearest tenth, if necessary. Hint: Use the Pythagorean T

Paul [167]

The distance between two points on the plane is given by the formula below

$\begin{gathered} A=(x_1,y_1),B=(x_2,y_2) \\ \Rightarrow d(A,B)=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2} \end{gathered}$

Therefore, in our case,

$A=(-1,-3),B=(5,2)$

Thus,

$\begin{gathered} \Rightarrow d(A,B)=\sqrt[]{(-1-5)^2+(-3-2)^2}=\sqrt[]{6^2+5^2}=\sqrt[]{36+25}=\sqrt[]{61} \\ \Rightarrow d(A,B)=\sqrt[]{61} \end{gathered}$

Therefore, the answer is sqrt(61)

In general,
