Answer:
D. 192
Step-by-step explanation:
This problem involves a few steps. First, you need to determine how many eighth graders you have given that 112 represent 70% of the total number of eighth graders. You can solve this using a proportion:
Cross-multiply and divide: 70x = 11200 or 70x/70 = 11200/70 or x = 160
Since there are 160 total eighth graders and this is of the amount of seventh graders, we can set up an equation to solve for the total amount of seventh graders:
160 = x
Multiply by the reciprocal of your fraction on both sides:
x 160 = x ()
Solve for x: x = 192 seventh graders
If you mean miles to yards you take the Miles times 1760 (there are 1760 yards in a mile)
Answer:
Number of vertices are <em>34</em>.
Step-by-step explanation:
The relation between the number of vertices, number of edges and number of faces was given by <em>Euler's formula</em>, which is as under:
Where is the number of faces in the polyhedron.
is the number of vertices in the polyhedron and
is the number of edges in the polyhedron.
Let us try to apply this formula in a cube. We know that number of vertices are 8, number of edges are 12 and number of faces are 6.
6 + 8 - 12
Hence, the formula is applicable.
Applying Euler's formula in the given question.
F = 14
E = 46
V = ?
Using Euler's Formula:
Hence, number of vertices are <em>34</em>.

Step-by-step explanation: I think it’s most likely to show text structure as a similar sentence is used earlier. :)
NO,313 IS NOT A REASONABLE ANSWER FOR HOW MANY MORE MILES LEE DROVE ON MONDAY THAN ON TUESDAY BECAUSE IF YOU SUBTRACT 135 FROM 248 YOU GET 213.
