Answer:
6.3 km.
Step-by-step explanation:
The question asks for kilometers, so all amounts have to be calculated in the same units -- kilometers.
Convert meters to kilometers.
600 m = .6 km
700 m = .7 km.
Add the amounts:
Fri.: .6 km
Sat. 3 km
Sun.: 2.7 km.

Answer:
4
Step-by-step explanation:
Answer:
If the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder, then its volume is
Use following formulas to determine volumes of sphere and cylinder:
wher R is sphere's radius, r - radius of cylinder's base and h - height of cylinder.
Then
Answer 1: correct choice is C.
If both the sphere and the cylinder are dilated by a scale factor of 2, then all dimensions of the sphere and the cylinder are dilated by a scale factor of 2. So
R'=2R, r'=2r, h'=2h.
Write the new fask volume:
Then
Answer 2: correct choice is D.
