(1/64)-5/6 = 32

To subtract fractions they must have common denominators, so find the least common multiple of 64 and 6 (the denominators of the fractions).

The least common multiple of the two fractions' denominators is 192. To get 64 to 192, you would multiply 64 by 3 times. If you're multiplying 64 by 3, you also multiply the numerator by 3.

1/64 * 3/3 = 3/192

Now to get 6 to 192, you would multiply 6 by 32. If you're multiplying 6 by 32 then you will also multiply the numerator (5) by 32.

5/6 * 32/32 = 160/192

Subtract the fractions now that they have common denominators. You'll only need to subtract the numerators.

3/192-160/192 = -157/192

You cannot simplify this any farther, so that will be your true answer. -157/192 is NOT equal to 32, so this means the answer is false.

Answer is:

false

In a trapezoid ABCD with legs AB and CD, the diagonals intersect each other at point O. Compare the areas of △ABO and △CDO.

ar(ΔABO) = ar(ΔCDO)

Explanation:

The image attached below.

Given ABCD is a trapezoid with legs AB and CD.

AB and CD are non-parallel sides between the parallels AD and BC.

In ΔABD and ΔACD,

We know that, triangles lie between the same base and same parallels are equal in area.

⇒ AD is the common base for ΔABD and ΔACD and they are lie between the same parallels AD and BC.

Hence, ar(ΔABD) = ar(ΔACD) – – – – (1)

Now consider ΔABO and ΔCDO,

Subtract ar(ΔAOD) on both sides of (1), we get

ar(ΔABD) – ar(ΔAOD) = ar(ΔACD) – ar(ΔAOD)

⇒ar(ΔABO) = ar(ΔCDO)

Hence, ar(ΔABO) = ar(ΔCDO).

8_murik_8 [283]

Answer:

x = 6 + 3√10

Step-by-step explanation:

Since this is an unfactorable expression, we need to apply the Quadratic Formula, -b ± √b² - 4ac\2a [radical wrapped around b² - 4ac]. Evaluate, then you will end up with the answer above.

You have for bookshelves, each 2 1/3 feet wide. How many feet of wall space will all 4 take up if they are placed into end?

Sladkaya [172]

Answer: 9 1/3

Step-by-step explanation: There are four of them and, assuming there is no space in between them, they all take up the same amount of space. So that means, if they were added up, it’d be 2 1/3 +2 1/3 + 2 1/3 +2 1/3. That can be simplified to 4 x (2 + 1/3). When multiplied, it equals 8 + 4/3=8 + 1 +1/3=9 + 1/3=9 1/3.
