Call it 2 for convenience: 

2 g/ml * ml/cm3 * 1kg/E3 g *(E2 cm/m)^3 
<span>= 2 E6/E3 = 2 E3 kg/m3 

Therefore, the answer is letter A. </span><span>1980 kg/m3

He used 53 pounds. I got this by using two equations.
a+b=117
and
5.8a+4.1b= 569.8

I took the first equation and subtracted 'b' so the equation looked like a=117-b.
I then plugged in 117-b into the second equation, so it ended up looking like this:
5.8 (117-b)=569.8
5.8 times 117 is 678.6. And 5.8 times negative b is negative 5.8b.
The equation now looks like this:
678.6-5.8b+4.1b=569.8
Add like terms
678.6-1.7b=569.8
Then subtract 678.6 from both sides
-1.7b= -108.8
divide each side by -1.7
you get b= 64.
But because you are looking for how many pounds for a, subtract 64 from 117. You get 53. 53 is the answer.

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w
Marysya12 [62]
The main formula we use here is Work=Rate*Time,


1. The rate (speed of working) of Dominik is 

r_D=1project/8hours= \frac{1}{8}(prj/h)

2. Let the the rate of Katarina be r_K=x(prj/h)

Together they have a rate of r_D_K equal to \frac{1}{8}+x (project per hour)

so (\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)

simplify the units:

(\frac{1}{8}+x) *5=1

\frac{1}{8}+x = \frac{1}{5}

x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
