Robin has 3 feet of ribbon. She uses part of it for a craft and has 2.5 feet left. She divides the 2.5 remaining feet among her 10 friends. How much ribbon does each friend receive? 0.25 feet
0.3 feet
25 feet
30 feetWhich gives the correct order of steps needed to multiply the problem below?

0.25 feet for each friend because 2.5/10=0.25

0.25 ft.

Step-by-step explanation

You have to divide 2.5 by the amount of friends she has so 2.5/10. Then you would moce the decimal one place forward. You would get 0.25.

Happy to help! Have a great day!

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).
