Answer:
Surface area: 250
Volume: 1375
Step-by-step explanation:
Scale factor: 4:5
This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So
Volume:
The volume is found multiplying the cube of the change(5/4) by the original volume(704). So

Answer:
z = 12xy
Step-by-step explanation:
Given z varies jointly with x and y then the equation relating them is
z = kxy ← k is the constant of variation
To find k use the condition when x = 2 and y = 3, z = 72, that is
72 = k × 2 × 3 = 6k ( divide both sides by 6 )
12 = k , then
z = 12xy ← equation of variation
Answer:
a. 2.25 km
Step-by-step explanation:
the scale on a map means how many units in the mapp corresponds to how many units in reality.
in this case
1 cm on the map = 75000 cm in reality =
= 75000/100 m = 750 m =
= 750/1000 km = 0.75 km
3 cm = 3×1 cm = 3 × 0.75 km = 2.25 km
The EER of a cooling system is the ratio of BTUs per hour to watts.
.. EER = (6000 BTU/h)/(500 W)
.. EER = 12
