Hal used the following procedure to find an estimate for StartRoot 82.5 EndRoot. Step 1: Since 9 squared = 81 and 10 squared = 100 and 81 < 82.5 < 100, StartRoot 82.5 EndRoot is between 9 and 10.

Step 2: Since 82.5 is closer to 81, square the tenths closer to 9.
9.0 squared = 81.00
9.1 squared = 82.81
9.2 squared = 84.64

Step 3: Since 81.00 < 82.5 < 82.81, square the hundredths closer to 9.1.
9.08 squared = 82.44
9.09 squared = 82.62

Step 4: Since 82.5 is closer to 82.62 than it is to 82.44, 9.09 is the best approximation for StartRoot 82.5 EndRoot.

In which step, if any, did Hal make an error?

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

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}
