If you have a lot of Pythagorean triples memorized, then you'd probably know immediately, but if not, then you can use the Pythagorean Theorem to calculate each one:
A.: 7^2+9^2=49+81 which is not equal to 13^2, or 169
B.: 5^2+12^2=25+144 which is not equal to 14^2, or 196
C.: 8^2+15^2=64+225=17^2=289
D.: 9^2+12^2=81+144 which isn't equal to 14^2, or 196
Therefore, the correct answer is C.
B 0.3
C 3
D 30
Answer:
0.003%
Step-by-step explanation:
you have to multiply this number by 100 which makes 0.3%
(-1/2)^-3
(1/2)^-3
2–3
Answer: second option. (NOTE: If the first option is , then it would be an equivalent expression too, because: )
Step-by-step explanation:
To solve this problem you must keep on mind the following exponents rule:
Therfore, you have that:
This means that the number -2 must be multiply by itself three times. Therefore, you obtain the folllowing result:
If the first option is , then it would be an equivalent expression too, because:
Answer:
.
