Megan and four of her friends plan to go for a long drive. She buys 12 bottles of frappe and a few bottles
of orange juice from a supermarket. The total number
of bottles they have are four times that of orange juice
bottles. How many bottles of orange juice did Megan
buy?

answer: '

the distance between points l and m

step-by-step explanation:

the correct answer is $7.38

step-by-step explanation:

answer:   2 multiplied by x =24

step-by-step explanation:

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
