Step-by-step explanation:
Pythagoras’ Theorem = a^2+b^2=c^2
c^2= 5^2+12^2
=25+144
=169
c= sqrt of 169
c=13
Hypotenuse=13cm
16/6.72 = 2.38... ounces per dollar
10/4.5 = 2.222... ounces per dollar
The 16 ounce deal is better, as you get more ounces per dollar
The correct answer is (C)!
Triangle IJK is an iscoceles triangle. Since the interior angle of a regular pentagon is 108°, Angle JIK = 36°.
Hence, Angle HIK = 108° - 36° = 72°.
If there are 48 tiles in each row then minus 48 - 6 white tiles = 42 purple tiles. And if there are 8 rows then 8 x 42 = 336. So Abigail needs 336 purple tiles.
