<span>A dust particle weighs 7.42 × 10-10 kilograms.

Weight of 5 × 106 dust particles = </span>5 × 10^6 x 7.42 x 10^(-10)

= 5 x 7.42 x 10^(6-10)

= 37.1 x 10^(-4)

= 3.71 x 10^(-3) kilograms

A building casts a 17-foot shadow. A 6-foot man standing next to the building casts a 2.5-foot shadow. What is the height, in fe

masha68 [24]

So the way you would find it is a ratio.

1. $\frac{6}{2.5} \frac{x}{17}$
2. =(6)(17)/(2.5)
3. =102/2.5
4. =40.8

So the building would be 40.8 feet tall.

The weight y of a object on Jupiter is proportional to the weight x of the object on earth. An object that weighs 150 ponds on e

mario62 [17]

Answer:

5.02 pounds

Step-by-step explanation:

y = k*x

Where,

y = weight of a object on Jupiter

x = weight of the object on earth

k = constant of proportionality

An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.

y = k*x

378.2 = k*150

378.2 = 150k

k = 378.2/150

= 2.5213

Approximately k = 2.52

determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth

y = k*x

12.64 = 2.52*x

12.64 = 2.52x

x = 12.64 / 2.52

= 5.0159

Approximately x = 5.02 pounds
