A(final)=16cm^2 ds/dT=6 da/dT=?

A=(s)^2 A=16cm^2 , s=sqrt(A) , s=sqrt(16) , s=4cm 

da/dT=2(s)(6cm/sec) , da/dT=12cm/sec(s) , da/dT=12cm/sec (4cm)

Answer should be da/dT=48cm^2/sec

The large rectangle below represents one whole. What percent is represented by the shaded area? (URGENT)

nikitadnepr [17]

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

$\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}$

Convert into a decimal:

$\frac{2}{5}= 0.4$

Multiply the decimal by 100 to get the percent:

$0.4*100=40$

So, forty percent of the rectangle is shaded.

Hope this helps.
