Howard bought 3/5 pounds of granola. He divided the granola evenly among 4 friends. How much granola did each friend get?
Alex17521 [72]

Answer:

(0.75) is the amount that each freind has.

Step-by-step explanation:

Sophie [7]

Answer:

She should take 112 steps west  

Step-by-step explanation:

* Lets explain the relation between the four directions

- North and South on the same line by in opposite directions

- East and West on the same line by in opposite directions

- East and West are perpendicular to the North and South

* Now lets study the situation i the problem

- Sally 100 steps due to South from the starting point

- Then she walk West when she gets the next clue

- The distance between her starting point and ending point is 150 steps

∵ The South is perpendicular to the West

- Lets consider her trip is a right angle triangle ABC, where AB

 her steps South and BC her steps West and AC the distance

 between her starting point and ending point

∵ AB = 100

∵ AC = 150

∵ m∠B = 90°

- By using Pythagoras theorem

∵ BC = √(AC² - AB²)

∴ BC = √(150² - 100²) = 50√5 = 111.8 steps

* She should take 112 steps west

nasty-shy [4]

Answer:

81.2\:\mathrm{ft}

Step-by-step explanation:

We can form a right triangle and use basic trig for a right triangle to solve this problem:

\tan33^{\circ}=\frac{h}{125}, where h is the height of the tree.

Solving, we get:

h=125\cdot \tan 33^{\circ},\\h\approx \fbox{$81.2\:\mathrm{ft}$}.
