Answer: 2 cakes and 2 slices of an extra ( assuming its cut into 10 slices)
Step-by-step explanation:
11 divided by 5 is equal to 2.2
in this case, 11 cakes divided by 5 friends is equal to 2 cakes and 2 slices.
normally you would just give them 2 cakes each (if you had 10 cakes) but you have 1 left over. So unless Sako wanted a cake as well, that's the answer(if she did, it would only be 2 cakes, no extra slices).
If you have a discount on an item..
ex. 15% off coupon for $20 shirt
20 x 0.15= $3 <--- 15% of 20
20-3=$17 <--- final price of shirt after coupon
To perform this check, you must use the following theorem: 
is a lower bound for the zeroes of 
if, when divide by 
, the quotient and the remainter alternate signs.
Since the long division yields the result
You can see that the signs don't alternate (the last two terms are positive). So, -1 is not a lower bound.
In fact, the actual roots of the polynomial are -3, -2, 1, 3, so as you can see there are roots smaller than -1.
4x + 8 = 4x +8
This means that there are in fine solutions since the expressions are equaled to each other.
tan(70)=12cm/y The tangent of the angle equals the opposite over the adjacent
y=12cm/tan(70) Isolate y and plug into calculator
y = 4.4 cm (Rounded to the nearest tenth)
