Yes all rectangles are similar but not all are equal, (geometry)
Let's think about what happens when you find the price after tax. Let the price before tax be
. The tax rate is
, so the tax part of the total price is
. Adding that onto the original price, we see that
So, we can just divide each side by
to get the original price, which rounded to two decimal places is
.
<span>we will use Thalès theorem
since triangle PRQ and ARC are similar
PR = QR = PQ
AR CR AC
so we can use
</span>PR = PQ
<span>AR AC </span>
but AR = CR finally, PQ = AC x PR / CR
PQ = <span>9.6 x 4.8 / 7.2 = 6.4</span>
the true answer is <span>6.4 inches</span>
525÷5= 105
its 105 for 1 notebook.
105×3= 315 for 3 notebooks.
hope this helps!
The weight of 10 fish would be 23.5 pounds. If 100 fish is 235 pounds, then each fish is 2.35 pounds. 10 fish of that same weight would be 23.5 pounds.
