There are 3.2 million teachers in the United States and 5.66 x 107 students. How many times more students than
Marat540 [252]

Answer:

602.42 million

Step-by-step explanation:

I know the answer is 602.42 million because I used addition and subtraction.

First, I knew there was 5.66x 107 million students. So, I multiplied 5.66 and 107, and I got 605.62 million. I knew there were 3.2 million teachers in the US. Next, I subtracted 3.2 million from 605.62 million.

605.62-3.2=602.42

So, there are 602.42 million more students than teachers in the United States.

Plzzzzz answer this question about density mass and volume!!!!!!!!!
nataly862011 [7]

Answer:

13.896 kg

Step-by-step explanation:

You can find the mass of the bar by first finding the volume.

V = BH

where B = area of the base (the trapezium), and

H = height (distance trapezium between bases)

The area of a trapezium is

A = (b1 + b2)h/2

where b1 and b2 are the lengths of the bases of the trapezium (the parallel sides), and

h = the altitude of the trapezium (distance between the bases of the trapezium)

V = (b1 + b2)h/2 * H

V = (12 cm + 6 cm)(5 cm)/2 * 16 cm

V = 720 cm^3

The volume of the bar is 720 cm^3.

Now we use the density and the volume to find the mass.

density = mass/volume

mass = density * volume

mass = 19.3 g/cm^3 * 720 cm^3

mass = 13,896 g

Now we convert grams into kilograms.

1 kg = 1000 g

mass = 13,896 g * (1 kg)/(1000 g)

mass = 13.896 kg

Answer: 1.3896 kg
