3. The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025

zalisa [80]

Answer:

Distance of Sun and Mercury = 58,000,000 km.

In Scientific notation, it would be: 5.8 × 10⁷ Km

Diameter of a human hair = 0.0025 cm

In scientific notation, it would be: 2.5 × 10⁻³ cm

Before Comparison, we need to bring centimeter to Kilometers or vice-versa, so we can easily calculate then, here, we will go from cm to Km.

2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸

Now, we can compare the values,

5.8 × 10⁷ Km > 2.5 × 10⁻⁸

[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]

A parking garage has 500 parking spaces. One morning 330 parking spots were filled. What percent of the parking spaces were fill

blondinia [14]

Hey there! :D

So, what we need to do is make a fraction that has a denominator of 100. This is the simplest route to take.

330/500

If you took one zero away from each side, you will get an equivalent fraction:

33/50

Multiply both side by 2 to get to 100.

33*2=66 50*2=100

66/100

So, 66% percent ornament the parking lots were filled.

I hope this helps!

Goshia [24]

Let the be the time in hours, and meters of fencing completed.

We know that After three hours, they have 15 meters of fencing complete, our graph will go from the point (0,0) to the point (3,15). We also know that they decide to take a 2-hour break for lunch and then resume building the fence, so our graph will go from the point (3,15) to the the point (5,15). Finally, After four more hours, they have a fence that is a total of 55 meters long, so the final part of our graph will go from the point (5,15) to the point (9,55)

We can conclude that the graph of t vs y is:
