Answer:
12 hours
Step-by-step explanation:
If we assume that the units of D are kg, then we can put the given number into the equation and solve.
21 = h +9
12 = h . . . . . subtract 9
Eli worked 12 hours to prepare 21 kg of dough.
The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:
5^2 - 10*5 + 25 = 0
25 - 50 + 25 = 0
0 = 0
Hope it helps!
Answer:
a polyhedron is a three dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.
a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense
polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.
solid geometry is the traditional name for the geometry of three-dimensional Euclidean space. Stereometry deals with the measurements of volumes of various solid figures including pyramids, prisms and other polyhedrons; cylinders; cones; truncated cones; and balls bounded by spheres
a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
Step-by-step explanation:
Answer:
1. proportional relationship
2. constant of proportionality
3. unit rate.
I'm not exactly sure on these answers, so please double check them for me to make sure that they are correct.
Step-by-step explanation:
C.) supplementary angles, complementary angles
Step-by-step explanation:
Look at the picture below.
A supplementary angle(s) has a total sum of 180°
A complimentary angle(s) has a total sum of 90°
Other angles like congruent, only refer to an angle that is exactly the same.
Therefore, C would be the correct answer.
