The block in this illustration is floating in water, which has a density of  1.00  g/cm3  . 
what is a good estimate of the density of the block if about 30 percent of the block is below water?

a. 0.30  g/cm3

b. 0.60  g/cm3

c. 0.90  g/cm3

d. 1.00  g/cm3

all but the second one

step-by-step explanation:

cuz that one goes over 180

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
