Answer:
the first answer is 10 and the second is 40
Step-by-step explanation:
there actually asking how many meters would make 1 centimeter
On the ruler 1 whole centimeter is 10 meter. (The longer line behind the number is the 10th meter )
Dividing fractions
1 ÷ 1/10
Steps
Change the whole number which is 1 into a fraction.
1/1 ÷1/10
Flip the second fraction in the equation.
1/1 ÷ 10/1
Then change the division sign to a multiplication sign. So were multiply instead.
1/1 × 10/1
Multiply the fractions and your answer should be 10/1 .
This fraction is also changed to a whole number.
10/1 = 10
Neither. When graphing both lines they intersect but are not perpendicular.
If we know your Pythagorean Triples we can immediately recognize that the last choice is a right triangle:
8² + 15² = 17²
If you don't know your Pythagorean Triples, it's worth learning the first few off the list because teachers use them in problems all the time. But for now let's just exhaustively check the Pythagorean Theorem for each triangle. We don't have to multiply everything out; we can analyze the common factors. If two have a common factor that the third one doesn't have, there's no way for the Pythagorean Theorem to add up.
Clearly 5²+15² is a multiple of 5 but 18² isn't so that one isn't a right triangle.
6²+12² is a multiple of 6, 16² isn't a multiple of 6, not an RT.
15²-5² is a multiple of 5, 13² isn't, no joy.
8²+15² = 64 + 225 = 289 = 17² -- that's a real right triangle, a valid Pythagorean Triple.
Answer:
Step-by-step explanation:
hello :
let : Z1 = 2-4i Z2 = 6+i
the distance between Z1 and Z2 is :
/Z2 - Z1 / = /(6+i)-(2-4i)/ =/4+5i/ = √(4²+5²) =√41
