Bryan needs to finish a book for
school. After 2 weeks, he has read
45 pages, and after 6 weeks, he has
read 135 pages. Find the rate of
pages per week that Bryan is
reading

22.5 pages per week

Step-by-step explanation:

Considering that After 2 weeks, he has read

45 pages, and after 6 weeks, he has

read 135 pages

Difference in weeks = 6-2=4 weeks

Difference in pages=135-45=90

Rate per week will be 90÷4=22½ pages per week

To prove this

If 1 week is 22½

2 weeks will be 2*22½=45

6 weeks will be 6*22½=135

Therefore, the reading rate is 22.5 or 22½ pages per week

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°

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
