20% off means that now it costs 80% of original price
80% = 0.8
costs 80% of (means here times (*))original price
29.99*0.8≈23.99
10% off means that now it costs 90% of original price
90%=0.9
costs 90% of (means here times (*))original price
26*0.9=23.40
23.99>23.40,
so is
<span> 10% off the original price of $26 is cheaper</span>
You divide left to right so you start at the three, hope this helps.
40+60+y=180
y=180-100
y=80
A triangle is 180° so you add all the numbers available in the trianle and minus it with 180 to see what is left from the 180 and that will be the inner angle answer
X=180-80=100
A straight line is also 180° so if u minused one side which in our case is 80 u will get the rest which is the outer angle
In order to solve a triangle, you need three of the six bits of information that define the triangle (3 angles, 3 sides), including at least one side. If you have one angle and one side, you only have two, not three. The triangle cannot be solved.
However, if your triangle is a right triangle, and the angle referred to in the problem statement is not the right angle, then you have the required information. In general, you make use of the definitions of the trigonometric functions. These can be remembered by the mnemonic SOH CAH TOA.
24000(total books) / 3000(batch of books with amount of errors known) = 8
8*3 = 24,
8*4 = 32
There will be between 24 and 32 printing errors.
