Answer:
1.99
Step-by-step explanation:
1000x6.99=6990
6990-5000=1990
1990/1000=1.99
No because it's negative 20 plus positive 40 So it's 20 percent more than the original
Answer:
27 : 1
Step-by-step explanation:
The faces of a regular tetrahedron are equilateral triangles. The incenter, circumcenter, and centroid are all the same point, located 1/3 of the distance from the edge to the opposite vertex of the face. The vertical height of the point that is 1/3 the slant height from the base is 1/3 of the height of the tetrahedron.
Then the "inscribed" tetrahedron has 1/3 the height of the original. The ratio of volumes is the cube of the ratio of linear dimensions, so the ratio of the larger volume to the smaller is ...
3³ : 1³ = 27 : 1
Answer:
The first one is 141 degrees, the second one is 39 degrees, the third is 149 degrees, the fourth one is 98 degrees, the fifth one is 102 degrees, the sixth one is 50 degrees, the seventh one is 74 degrees, the eighth one is 83 degrees, the ninth one is 95 degrees, the tenth one is 162 degrees.
Step-by-step explanation:
Basically you can look at the lines and tell if they are the same degree or not and if they are not you subtract that number from 180 to get your degree. I've already done this worksheet before and got a 100%
