You have 2+2 in each 2 there are 1's so

2=(1+1) 2=(1+1) =4
4=1+1+1+1
2+2=4
think of 2's as 1's when adding did you know 2x2= 4 as well.

$\huge \boxed{\mathfrak{Question} \downarrow}$

You are driving from Show Low to Portland, Oregon. The trip will be 1,345 miles total. So far, you have driven 3/5 of the way to Portland. How many miles do you have left to drive?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Now, let's solve it.

$\sf1345 \times \frac{2}{5} \\ \sf = \bcancel{1345} \times \frac{2}{ \bcancel{5}} \\ \sf = 269 \times 2 \\ = \boxed{ \boxed{ \bf \: 538}}$

area=(pi)(r)^2=(pi)(d/2)^2
= (pi)(2.2/2)^2
= 1.21 (pi) m^2

Answer:

50.265(correct to 5 significant figure)/ 16π

Step-by-step explanation:

$\pi({8}^{2} )( \frac{90degree}{360degree} )$

$= \pi(64)( \frac{1}{4} )$

=50.265(cor. to 5 sig.fig.)/ 16π

to find the arc length of a sector,we need to use πradius² times (sector's degree divided by 360degree).
