Make the conversion indicated ineach of the following:
(a) the length of a soccer field, 120 m (three significant figures), to feet
(b) the height of mt. kilimanjaro, at 19,565 ft the highest mountain in africa, to kilometers
(c) the area of an 8.5 t 11-inche sheet of paper in cm2
(d) the displacement volume of an automobile engine, 161 in 3, to liters
(e) the estimated mass of the atmosphere, 5.6 t 1015 tons, to kilograms
(f) the mass of a bushel of rye,32.0 ib, to kilograms
(g) the mass of a 5.00-grain aspirin tablet to miligrams(1 grain = 0.00229 oz)

Explanation:

(a) The length of a soccer field, 120 m (three significant figures), to feet.

1 m = 3.28084 feet

(b) The height of Mt. Kilimanjaro, at 19,565 ft the highest mountain in Africa, to kilometers

1 feet = 0.0003048 km

(c) The area of an 8.5 ×11-inche sheet of paper in .

Area of the sheet = 8.5 inches × 11 inches = 93.5

(d) The displacement volume of an automobile engine, 161 , to liters.

(e) The estimated mass of the atmosphere, , to kilograms.

1 ton = 907.185 kg

(f) The mass of a bushel of rye,32.0 Ib, to kilograms

1 lb = 0.453592 kg

(g) The mass of a 5.00-grain aspirin tablet to milligrams.

(1 grain = 0.00229 oz)

Mass of 5 grains = 5 × 0.00229 oz = 0.01145 oz

1 oz = 28349.5 mg

the answer is true. hope it .
