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
Answer:
WHAT PICTURE
Step-by-step explanation:
2(p+1)=24
divide both sides by two
p+1=12
subtract 1 from both sides
p=11
Answer:
C
Step-by-step explanation:
Complementary means that the angles have a sum of 90° so we can write:
m∠A + m∠B = 90° → 3x + 2 + 8x = 90
11x + 2 = 90
11x = 88
x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.
