Molly invested $50,000 in various stocks
and bonds. She earned 15% on the bonds
and 18% on the stocks. If Molly's total
profit on both types of investment was
$8,700, how much of the $50,000 did she
invest in bonds?
00, how im types of : lt Molly's me!

  $10,000

Step-by-step explanation:

Let b represent the amount invested in bonds. Then 50,000 - b wil be the amount invested in stocks. Molly's total return is ...

  0.15b + 0.18(50000-b) = 8700

  -0.03b +9000 = 8700 . . . . simplify

  300 = 0.03b . . . . . . . . . . . . add .03b-8700

  10,000 = b . . . . . . . . . . . . . divide by 0.03

Molly invested $10,000 in bonds.

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).

lol we need to see what the question is asking about
