Charles has a rectangular flower garden that is 5 yds long and 12 yds wide, one bag of fertilizer can cover 6 yds .how many bags will he need to buy to cover the entire garden

10

Step-by-step explanation:

first we need to find the area of the garden, or how much space we need to cover.

A = length * width, so 12 * 5 = 60

if one bag covers 6 yards, then 60 / 6 = 10

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
