Answer:
Approximately 14.42
Step-by-step explanation:
All you have to do is use the Pythagorean Theorem! In case you don't remember, it's a² + b² = c², where a and b are legs and c is the hypotenuse.
So...
8² + 12² = c²
64 + 144 = c²
208 = c²
= 14.42
Answer: b. counterexample
A counterexample contradicts the statement or definition you're trying to set up.
For example, if you said that 2x+3x = 7x was true for all x values, then all you need to do is try something like x = 2 to find the original equation simplifies to 10 = 14, which is false. In this case, the counterexample is x = 2 invalidating the equation 2x+3x = 7x.
Surface area of the cylinder is 294π in².
Step-by-step explanation:
- Step 1: Surface area of a cylinder = 2πrh + 2πr² Here, r = 7 in, h = 14 in
⇒ Surface Area = 2 × π × 7 × 14 + 2 × π × 7 × 7
= π (196 + 98) = 294π in²
Step-by-step explanation:
now, really !
you don't know, if 0 is larger than 16.4 or smaller than -16.4 or ... ?
0 is right between any negative and positive numbers. in integer view between -1 and +1.
0 is therefore larger than any negative number, and smaller than any positive number.
and -0 = +0 = 0
so, I hope, the position of 0 on the line of all numbers is now clear.
and it is also clear that when you multiply 0 with something else, the result is always 0. right ?
so, of course,
a
is correct.
0 is not greater than 16.4 (kills b and c).
0 is not smaller than -16.4 (kills d).
110 x 1.73 = 190.3 rounded -> 190.30
Final answer: 190.30
