1gcm-³ = 1000kgm-³
so 2.7gcm-³ = 2700kgm-³ (density)
volume = 1×0.6×0.3m³ = 0.18m³

mass = density ×volume = 2700×0.18 Kg = 486Kg

Answer:

620.14

Step-by-step explanation:

Original Equation:

\frac{4y}{1.025^4}+y-2y(1.05)^2=1500

Calculate exponents

\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\

Simplify:

3.6238025791990193084270042653997y + y - 2.205y = 1500

Add like terms

2.4188025791990193084270042653997y \approx 1500

Divide both sides by 7.012

y\approx 213.91y\approx620.14

S=L (1 - r), for r
maria [59]
OK. Then let's solve for ' r '.  That means you have to come up with an equation that says     r =    everything else.

Step #1: 
Write the equation you're given:   <span>S = L (1 - r)

Let's divide each side by ' L ':      S/L = 1 - r

Subtract 1 from each side :         S/L - 1 = -r

Multiply each side by -1 :          <em>  1 - S/L = r</em>

and there you have it.
