What is the distance across the river in feet?

375 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

= ( cross- multiply )

10d = 3750 ( divide both sides by 10 )

d = 375 ft

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

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}
