11-a is false, because 10/28 can only be reduced to 5/14. 11-b is false, because 6/12 can be reduced to 1/2 ( 1/2 and 2/4 are equal though, but are not both in simplest form ) Finally, 11-c is true, 2/14 can be reduced to 1/7.

AC is diagonal of square ABCD, and the length of AC is 4. What is the area of the square?
dybincka [34]
Option d.
as we know the corner of a square is always 90°. So we can apply that (side of the square)^2+(side of the square)^2 = (diagonal of the side)^2

(side of the square)^2+(side of the square)^2 = 16
16/2=8
8=(side of the square)^2
side of square= squareroot of 8
area of square= squareroot of 8^2=8
hence answer is 8

Brad says that if a second number is 125% of the first number than the second number must be 75% of the second number is he corr
elena-s [515]

Answer:

Incorrect.

Step-by-step explanation:

Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be

y = 1.25 x

Or, y= 5/4x

Now, multiplying it with 4/5, we get, x= 4/5y

Or, x= 0.80 y

But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That's why Brad is incorrect.
