Answer:
27
Step-by-step explanation:
1 mile took 9 min to run, so 3 miles will be:
3 x 9 =
27
Volume = Length × width × height
V = 4×4×8 = 128 cubic ft
3rd answer always solve parenthesis first use PEMDAS
For this case we have that by definition, the distance between two points is given by:

We have the following points:

Substituting we have:

Thus, the distance between the points is
Answer:

Sinα=h/d
h=dsinα, since d=10km and α=13
h=10sin13 km
h≈2.24951km
h≈2.2 km (to nearest tenth of a kilometer)
