Answer:
5.543 miles
Step-by-step explanation:
The law of cosines can help with this. It relates side "c" of a triangle to the other two sides (a, b) and the angle between them (C).
c² = a² +b² -2ab·cos(C)
c² = 3² + 3² -2·3·3·cos(135°) = 18(1 -cos(135°)) ≈ 30.7279
c ≈ √30.7279 ≈ 5.543 . . . . miles
Answer:
14/5
Step-by-step explanation:
So first i manipulated a/b= 2/5. i multiplied both sides by 5 making it 5a/b=2. Then i multiplied both sides by b making it 5a=2b. Then i substituted 2b into 5a+3b=35. Making it 2b+3b=35. then i simplified it making it 5b=35. Then i solved for b making it b=7. Then i substituted b into 5a+3b=35. So that it looked like this 5a+3*7=35. then it became 5a+21=35. Then you subtract 21 making it 5a=14. You then divide by 5 making it a=14/5
5% is just another way of writing 5/100
So we have 5/100 of 88.5 → 5100×88.5
This is the same as 5×88.5/100=5×0.885
But 5 is 1/2×10
So we can write 5×0.885 as 1/2×10×0.885
=1/2×8.85=4.425
hope it helps!
The answer is C. 6 times 4 is 24 and 1/4 times 4 is 1. therefore 24 + 1 = 25
