The new length of the string is (16 + 1/4) feet, then the correct option is the second one (counting from the top)
We know that the current string was (7 + 3/4) feet in length. Then they add another piece that measures 8.5 feet.
The new length of the string is given by the addition of the above two lengths, we will get:
L = (7 + 3/4) feet + 8.5 feet
We can rewrite the second length as a mixed number:
8.5 = 8 + 1/2 = 8 + 2/4
Replacing that we get:
L = (7 + 3/4) ft + 4.5 ft
= (7 + 3/4) ft + (8 + 2/4) ft
= (7 + 8) ft + (3/4 + 2/4) ft
= 15ft + 5/4ft = 15ft + (4/4 + 1/4)ft = (16 + 1/4)ft
The new length of the string is (16 + 1/4) feet, then the correct option is the second one (counting from the top)

Answer:
Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. A scratch test developed by a German mineralogist Friedrich Mohs in 1822 is used to determine mineral hardness.
This is a point giveaway? Lol
Answer:
14
Explanation:
For independent variables X and Y;
S.D(X - Y) is expanded as :
S.D(X) + S.D(Y)
If S.D(X) = 6 and S.D(Y) = 8 ; where, X and Y are independent ;
SD(X-Y) = SD(X) + SD(Y)
SD(X - Y) = 6 + 8
SD(X - Y) = 14
