A cell phone plan costs $30.70 per month for 700 minutes of talk time. It costs an additional $0.05 per minute for each minute over 700 minutes. To get e-mail access, it costs 10% of the price for 700 minutes of talk time. Your bill, which includes e-mail, is the same each month for 9 months. The total cost for all 9 months is $339.03. Write and solve an equation to find the number of minutes of talk time you use each month. Let m represent the number of minutes over 700 minutes each month. Which equation represents the given situation?
A.
339.03=9(m+30.70+0.90(30.70))
B.
339.03=9(0.05m+30.70+0.10(30.70)) Your answer is correct. C.
339.03=9(m+30.70)
D.
339.03=9(0.05m+30.70)
You use _ minutes of talk time each month.

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

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
