A sailboat on a lake sails 90. meters north and then sails 60. meters due east. Compared to its starting position, the new position of the sailboat is show your work

The new position of the sailboat is 108.2 m, at N 53.3° E

Explanation:

From the image uploaded, R is the resultant displacement and it is calculated as;

R² = 90² + 60² (Pythagoras theorem)

R² = 11700

R = √11700

R = 108.2 m

The direction of the boat is given by θ in the image uploaded;

tanθ = opp/adj

tanθ = 90 / 60

tanθ = 1.5

θ = tan⁻¹(1.5)

θ = 53.3°

θ = N 53.3° E

Therefore, the new position of the sailboat is 108.2 m, at N 53.3° E

i would think it's food chain

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
