1. mina bought a plane ticket to new york city and used a coupon for 10% off the ticket price. the

total cost of her ticket, with the discount, was $253.10. which equation could she use to find the

price of the ticket without the discount?

Step-by-step explanation:

Let x represent the price of the ticket without the discount.

The cost of the ticket after discount would be x minus 10% of x.

10% of x:

We have been given that the total cost of ticket with 10% discount is $253.10. We can represent the given information in an equation as:

Therefore, Mina could use the equation to find the price of ticket without the discount.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
