Which is a focus of the hyperbola shown? (−20, 0) (−24, 0) (25, 0) (30, 0)

You have marked the correct answer.

Step-by-step explanation:

The distance from the center to the focus is the same as the distance from the center to the corner of the dashed green rectangle shown (not to scale). The hypotenuse of a rectangle with legs 7 and 24 is √(49+576) = 25, so the distance will be 25 from (0, 0) to the focus at (25, 0).

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
