Answer:
$39.24
Step-by-step explanation:
Let's determine the sale price before tax:
0.40($60) = $24 is the discount, so
the sale price is $60 - $24, or $36.
Multiplying this result by 1.09 results in the total price, including tax. It is $39.24.
Answer:
-16 and 24
Step-by-step explanation:
-16 x 24 = -384
-16 + 24 = 8
<u>A=1/2h(b1+b2)</u>
= 1/2(h)(30+16)
<em>>how to find h<</em>
<em>>30-16= 14/2 = 7<</em>
<em>>25²-7² = 625-49 = 576<</em>
<em>>√576 = 24 .. h=24<</em>
= 1/2(24)(30+16)
= 12(46)
A = 552 cm²
<u>P= b+b+l+l</u>
= 30+16+25+25
P = 96 cm
SinФ=-12/13
cosФ=Base/hypotenus
(hy)^2-(perpendicular)^2=(base)^2=13^2-12^2=5
cosФ=-5/13
