Ineed the answer to these math questions.
1) multiply 16 minutes 21 seconds by 31.
2) divide 537 minutes 20 seconds by 31.
3) divide 999 hours 45 minutes by 43.
round the final answer to the nearest hundredth as necessary.

1) 506.85 minutes

2) 17.33 minutes

3) 23.25 hours

Step-by-step explanation:

1) 16 minutes and 21 seconds

16 minutes and 21 seconds=16.35 minutes

Multiply by 31

2) 537 minutes 20 seconds

537 minutes 20 seconds=537.33 minutes

Divide by 31

3) 999 hours 45 minutes

999 hours 45 minutes=999.75 hours

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
