Perform the following conversions.
a. 0.074 km to m
b. 24,600 μg to g
c. 4.9 × 107 μg to kg
d. 84 dm to mm

a. 74 km

b.  .0246g

c. = .049 kg

d.  8400mm

Explanation:

a. 0.074 km to m

1000 meters is 1 km

.074 km* 1000m /1 km = 74 km

b. 24,600 μg to g

10^6 ug is 1 gram

24600 ug * 1 g/ 1000000 ug = .0246g

c. 4.9 × 10^7 μg to kg

4.9 × 10^7 μg* 1 g/ 1000000 ug * 1kg/1000g  = .049kg

d. 84 dm to mm

84 dm * 100 mm/ 1dm = 8400mm

A.

we know that, 1km=1000m

B.

we know that, 1000000μg=1g

C.

we know that, 1000000000μg=1kg

D.

we know that ,100mm=1dm

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
