Pls convert 1 3/8 and 3 1/2 both into a decimal

Step-by-step explanation:

1) See below how to convert this mixed number to a decimal:

Step 1: divide numerator (3) by the denominator (8):

3 ÷ 8 = 0.375

Step 2: add this value to the the integer part:

1 + 0.375 = 1.375. So,

1 3/8 = 1.375

Approximated Values:

1 3/8 = 1 rounded to 1 significant figure

1 3/8 = 1.4 rounded to 2 significant figures

2) Step 1: divide numerator (1) by the denominator (2):

1 ÷ 2 = 0.5

Step 2: add this value to the the integer part:

3 + 0.5 = 3.5. So,

3 1/2 = 3.5.

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
