Answer:
11) 662
12) 24
Step-by-step explanation:
2 (11x11x11 - 1000) = 2(1331-1000)
= 2(331) = 662
1/8 (256 - 64)
= 1/8 (192)
= 198/8 = 24

4/5-1/3
(4.3/5.3)-(1.5/3.5)
12/15-5/15
7/15
For this question, we have to use the Pythagorean theory since we're dealing with a right triangle.
a² + b² = c²
We're given the value of the hypotenuse and a leg, therefore we're looking for the value of the other leg.
Now let's plug in the given data into our equation.
2² + b² = 5²
4 + b² = 25
b² = 25 - 4
b² = 21
√b² = √21 = b
The correct answer is B) √21
