How high is a stack of library books in one book is one and 3/8 in high the second book is one and 5/6 in high and the third is 2 1/3 in high explain how you solve this problem?

3 7/8 inches high

Step-by-step explanation:

You convert mixed numbers into improper fractions and use the LCM property in order to add all the numbers together

OK i was right the first time

I hope this helped and I hope it is right:)

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
