HURRY. NEED To be done by 10:30 The chart below shows how much Ms. Reyes spent on a
recent trip. What is the total amount of money she spent?
Ms. Reyes' Trip Expenses
plane ticket
hotel
rental car
meals
$312
$287
$112
$111
OA) $205.50. OB) $822. OC) $832. OD) $842

B) $822

Step-by-step explanation:

The total amount of money she spent can be found by adding her expenses:

312 + 287 + 112 + 111

Once added you get the total amount of:

$822

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).

it should be a and d. lmk if i'm wrong xd
