I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
C that is the right answer
Answer:
1.26885245902 or rounded to $1.27 per pound.
Step-by-step explanation:
you can just divide 3.87/3.05 to see how much each pound costed. if you needed to round to the nearest cent, you would round up to 1.27.... or if not, keep it at 1.26885245902.
then to check your work, you can just multiply (1.26885245902) by (3.05) to get the total amount she had spent.
The point (-11,34) has the coordinates x = -11 and y = 34
The point (47,0) has the coordinates x = 47 and y = 0
Let's focus on just the x coordinates of each point for now. Those values are -11 and 47. Add them up to get -11+47 = 36. Then divide by two to end up with 36/2 = 18
The x coordinate of the midpoint is x = 18
Repeat those steps for the y coordinates. First add them up: 34+0 = 34. Then divide by two: 34/2 = 17
The y coordinate of the midpoint is y = 17
<h3>Therefore the midpoint is located at (x,y) = (18,17)</h3>
--------------------------
side note:
If you want, you can use the formulas
xm = (x1+x2)/2
ym = (y1+y2)/2
where (x1,y1) and (x2,y1) are the two endpoints and (xm, ym) is the midpoint. Though this method may be a bit confusing.
Answer:
B
Step-by-step explanation:
To find the slope, find the vertical distance and the horizontal distance between the points. Then write the distances as a ratio.
6 - 3 = 3
0.4 - 0.2 = 0.2
The slope is 3/0.2 = 15.
