Sharlay has 2 quarters, 5 dimes, and 3 nickels in her pocket. She pulls coins from her pocket one at a time without putting any back into her pocket What is the probability that the first coin she pulls is a quarter and the second coin is a dime? А 1 9 B 10 1 5 D 7 10​

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

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
