Answer:
1 cm^2 = 100 mm^2
9 cm^2 = 900 mm^2
5.2 cm^2 = 520 mm^2
1 dm^2 = 100 cm^2
17 dm^2 = 1700 cm^2
4.3 dm^2 = 430 cm^2
1 m^2 = 10000 cm^2
7 m^2 = 70000 cm^2
2.5 m^2 = 25000 cm^2
1 km^2 = 1000000 m^2
50 km^2 = 50000000 m^2
8.5 km^2 = 8500000 m^2
Step-by-step explanation:
1 cm = 10 mm
1 
= 10×10 
= 100
9 = 9×100 = 900
5.2 = 5.20×100 = 520
1 dm = 10 cm
1 
= 10×10 = 100
17 = 17× 100 = 1700
4.3 = 4.3 × 100 = 430
1 m = 100 cm
1 
= 100×100 = 10000
7 = 7×10000 = 70000
2.5 = 2.5×10000 = 25000
1 km = 1000 m
1 
= 1000×1000 = 1000000
50 = 50×1000000 = 50000000
8.5 = 8.5×1000000 = 8500000
the answer to this question is 55 cm
Answer:
B) 4 miles
Step-by-step explanation:
the big triangle CAB and small triangle CED are simular (given)
this means the ratio between their corresponding sides will be the same.
find corresponding sides with alternate interior angle theorem
m CDE= m CBA
vertical angles theorem
m ACB = m DCE
therefore, AC corresponds to CE
find ratio of sides
7 miles = 36960 feet
36960/ corresponding side 21 ft
36960/ 21= 1780 ft
multiply by 1780 to get from small side to big side
small side CE = 12 ft
12*1780
=21120 ft =AC (in ft)
convert to miles (ft to miles is ft/5280)
21120/5280
=4 miles
hope this helps
The answer to this question is x=4
