Marc baked brownies in the brownie pan shown below. each day, he is going to eat 20 square centimeters of brownie from the pan.

for how many days does marc have brownies before they run out?

the shape is a trapezoid with the top part being 29 cm in length, and the bottom being 41 cm in length. the height is 20 cm.

Step-by-step explanation:

step 1

Find the area of the trapezoid (brownie pan)

step 2

To find the number of days , divide the area of the brownie pan by 20 square centimeters of brownie

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
