Let Paul's house be at the origin of a coordinate grid. then Mary lives at (-6,-9) and Benjamin lives at (7,3). using the distance formula for these two points gives us d=√(-6-7)² + (-9-3)².
d=√169+144 or√313 miles, or about 17.69 miles.
I'm thinking maybe x is supposed to represent the number of tasks completed because it states Shelly earned 90 points on each task. Then when put together it may look like this, let's say there are 4 tasks= Ex.90 times the 4 tasks minus 20 points which would total the points Terrence's has earned. So i believe x is the total tasks. Hope I didn't make it confusing...
Answer:
All the mentioned can be constructed with the help of piling method. But, for construction of b and d we need a point as well.
Step-by-step explanation:
a) Yes, a cube can be formed by stacking polygons. If we stack squares one upon another, then the resulting 3-D figure would be a cube.
b) Yes, a cone that does not include the point can be made by stacking disc. If we stack discs such that the discs are arranges in descending order then the resultant 3-D figure would be a cone that does not include a point.
c) Yes, a pyramid can be formed by stacking polygons.
If we stack squares such that they are arranged in descending order of their side length and stacked by a point on the top. Then the resultant figure would be a pyramid that includes a vertex.
f) There are many types of prism. Fro example a rectangular prism can be constructed by simply stacking rectangle polygon on one another.
e) Yes, a cone can be formed by stacking disc.
We need to stack disks arranged in descending order of their radius stacked with a point on the top. The resulting figure would be a cone that includes a point.
f) Yes, a cylinder can be formed by stacking. We need to stack discs of same radius to get a cylinder.
Answer:
Rope 4
Step-by-step explanation:
A yard is 3 feet and a foot is 12 inches, which means a yard is 36 inches. 9 is 1/4 of 36, so Rope 4 is exactly 9 inches long.
