2. Suppose (220)_b and (251)_b are the squares of consecutive integers. Determine b.

Andrei [34K]

Let $x$ and $x+1$ be these consecutive integers. For some base $b$ , we can write

$(x_{10})^2=220_b=2b^2+2b$

$((x+1)_{10})^2=251_b=2b^2+5b+1$

$x^2=2b^2+2b$

then

$x^2+1=2b^2+2b+1$

Now,

$x^2+2x+1=2b^2+5b+1$

$2x+2b^2+2b+1=2b^2+5b+1$

$\implies2x=3b$

Squaring both sides gives

$4x^2=9b^2$

and so

$4(2b^2+2b)=9b^2$

$\implies8b^2+8b=9b^2$

$\implies b^2-8b=0\implies\boxed{b=8}$

(because the base has to be non-zero)

Lily hikes at least 1 hour but not more than 3 hours. She hikes at an average rate of 2.2 miles per hour. The distance Lily hike

Basile [38]

Average rate = distance / time
distance = average rate x time

Range of distance = 2.2(1) to 2.2(3) = 2.2 to 6.6

Required range is all real numbers from 2.2 to 6.6, inclusive.

Write 9.753 in words

vlabodo [156]

Hey there! :D

When you write out decimals, you use words that end with 'ths'. And you use the smallest digit's place to name the whole decimal.

For example,

.1 = one-tenths .25= twenty hundreths .345= three hundred and forty five thousandths

9.753= Nine and seven hundred fifty-three thousandths.

I hope this helps!
