Answer:
Option A, 300 - 20w
Step-by-step explanation:
In a week, she withdraws $20
in w weeks, she will withdraw ; w × 20
= 20w
Balance = Initial amount - Amount withdrawn
= 300 - 20w
Answer:
She will need 7 tanks of gas. It will cost $273.
Step-by-step explanation:
First, we divide the amount of miles that she needs to go by the amount she can drive on one tank.
2240/320 = 7
She will need 7 tanks. Multiply the cost of one tank by 7.
$39*7 = $273
It will cost $273 total.
Answer:
tanΘ = - 
Step-by-step explanation:
Using the trigonometric identity
tan²Θ + 1 = sec²Θ, thus
tan²Θ + 1 = (
)² = 
( subtract 1 from both sides )
tan²Θ = 
( take the square root of both sides )
tanΘ = ± 
Since 270 < Θ < 360 , that is the fourth quadrant where tan Θ < 0, thus
tanΘ = -
