Answer:
56
Step-by-step explanation:
area of whole figure=
l×b
=20×10
=200
also,area of small fig.
=l×b
=18×8
=144
thus area of shaded part =a of whole- a of small
=200-144
=56
We are asked to express r in terms of A, P, and t.
We first divide both sides of the equation by t, which gives us
![\displaystyle{ \frac{A}{t}=P(1+r)](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7BA%7D%7Bt%7D%3DP%281%2Br%29%20)
,
then, dividing both sides by P, we have
![\displaystyle{ \frac{A}{Pt}=1+r](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7BA%7D%7BPt%7D%3D1%2Br%20)
.
Swap the sides:
Finally subtracting 1 from both sides gives us
![\displaystyle{ r=\frac{A}{Pt}-1](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20r%3D%5Cfrac%7BA%7D%7BPt%7D-1)
.
Answer:
OML
Step-by-step explanation:
How would anyone know this
<span>We will start using a new way to indicate simplifying fractions. When a numerator or
a denominator gets simplified, we will cross it out with a slash and write the new
numerator or denominator next to it (either above it or below it).</span><span>The number you divide by (the 4) does not get indicated in any way! You only
think about it in your mind: “I divide 12 by 4, and get 3. I divide 20 by 4, and get 5.”</span><span>You may not see any advantage over the “old” method yet, but this shortcut will
come in handy soon.</span> <span />
