Carl wants to find the product 30×5/6.Which of the following best explains how he can find the product mentally? A. He knows that 30÷5 is 6. He then multiplies 6 by 6 to get 36.
B. He knows that 30×6/6 is 30. He then subtracts 1 from 30 to get 29.
C. He knows that 3×6=18.He then adds 18 and 5 to get 23.
D. He knows that 30×1/6 is 5. He then multiplies 5 by 5 to get 25.

D

30×5/6 = 25

Step-by-step explanation:

:))

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
