Answer:
Step-by-step explanation:
Use KCF method for fraction division.
Keep the first fraction
Change the operation to multiplication
Flip the second fraction.
1) 3÷ (1/4) =
2) 7 ÷ (1/2) =
3) (1/5) ÷ (1/20) =
4) (1/2) ÷ (1/10) =
5) (1/7) ÷ 3 =
Answer:
49
Step-by-step explanation:
Complementary angles always add up to 90 degrees, so make and equation. First, say that angle ABC and angle QRS add up to ninety degrees. Substitute the values to get 41 degrees plus angle QRS equals 90 degrees, and once you subtract 41 from both sides, you get angle QRS equals 49 degrees.

Answer:
5 km would be the answer
Step-by-step explanation:
For 45-45-90 triangles, the values are x, x, for the less long sides, then for the hypotenuse it's x sqrt2, because that is the rule for 45-45-90 triangles. So since in this problem, the value for the hypotenuse is 5sqrt2 km, the c value would be 5 km. Hope this helps!
Is it 5/4? Because I don't understand your question.
