Sally works for mailworks stuffing envelopes. she is paid $0.20 for each envelope she stuffs. how much does she earn for a week in which she stuffs 523 envelopes?

 Second option is correct.

Step-by-step explanation:

Since we have given that

Number of envelopes = 523

Cost of each envelopes = $0.20

So, total cost she earn in which she stuffs 523 envelops is given by

Hence, Total cost is $104.60

therefore, Second option is correct.

1,918

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
