] I 1 ! 1 1 2 5 7 I Find the GCF: Ladder Method Read the word problem. Find a number that will evenly divide into both numbers. Write that number on the left side of the "ladder rung" and divide each number by your chosen factor. Repeat the process until the only common factor is "1". Don't forget to write your answer in a complete sentence. 1) Ms. Soto has 15 boys and 10 girls in her class and would like to arrange their desks so that there are only boys or girls in each row. If there are the same number of students in each row, what is the largest row Ms. Soto can make? Answer

5

Step-by-step explanation:

The largest row she can make would be 5 because 5 can go into 15 and 10.

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).
