Gemma

9 X 150 = 1350

61000/100 X 2 =1220

add together $2570

Fred

14350/100x2=287

200 + 287 = $487

Erik

4 X 160 = 640

153000/100 X 2.5 = 3825

3825 + 640 = $4465

Does anyone know how to do this ?

Answer:

w=3 h=4

Step-by-step explanation:

14=2w+2h w=(3/4)h

substitute

14=2(3/4)h+2h

distribute

14=1.5h+2h

simplify

14=3.5h

divide both sides by 3.5

4=h

plug into original equation

w=(3/4)4

w=3

If one atom of carbon weighs 1.99 × 10^−22 g and one atom of hydrogen weighs 1.67 × 10^−27 g, which element weighs more? Explain

garik1379 [7]

Answer:

The atom of carbon weighs more

Step-by-step explanation:

we have

<em>Atom of carbon weighs</em>

$1.99*10^{-22}\ g=1.99*10^{-22}(\frac{10^{5}}{10^{5}})=199,000*10^{-22}(\frac{1}{10^{5}})=199,000*10^{-27}\ g$

<em>Atom of hydrogen weighs</em>

$1.67*10^{-27}\ g$

Compare

$199,000*10^{-27}\ g > 1.67*10^{-27}\ g$

therefore

The atom of carbon weighs more
