Answer:  The correct option is (B) 16 meters.

Step-by-step explanation:  As shown in the attached figure, ABCD is a rectangle with length 63 m, width x m and diagonal 65 m.

We are given to find the value of x.

Since all the four angles of a rectangle are right angles, so triangle ABD will be a right-angled triangle, where

∠BAD = 90°, AB = 63 m, AD = x m and hypotenuse, BD = 65 m.

Using Pythagoras theorem, we have from triangle ABD that

BD^2=AB^2+AD^2\\\\\Rightarrow 65^2=x^2+63^2\\\\\Rightarrow x=\sqrt{65^2-63^2}\\\\\Rightarrow x=\sqrt{4225-3969}\\\\\Rightarrow x=\sqrt{256}\\\\\Rightarrow x=16.

Thus, the value of x is 16 meters.

Option (B) is CORRECT.

A cook has 11 7/8 cups of flour. He uses 2/3 of his flour on Saturday morning. Estimate how many cups he used. Show how you esti
ziro4ka [17]

Answer:

11 (if you wanna know how many cups [which i mean by 2/3] it is 1)

Step-by-step explanation:

Well, to start, a cook has 11 7/8 cups of flour, right? Well, if you subtract 11 7/8 by 2/3 you get 11 5/24. As an estimate, you would get just plain 11 because there is three numbers when you estimate, 11, 11 1/2, or 12. 11 5/24 is more closer to 11 (because 1/2 would be 11 12/24, and 12 would be 11 13/24 or more until 12)

Hope it helped...
