Answer:

4 m.

Step-by-step explanation:

Length of ladder, L = 4.50 m

Base of ladder from the wall, B = x

Height of the wall, H = 2x

Using Pythagoras theorem

L^2 = B^2 + H^2

4.5^2 = x^2 + (2x)^2

5x^2 = 4.5^2

x = 2\ m\ (approx.)

Height of the wall  is equal to 2 x 2 = 4 m.

What is 3 1/8 - 1/2
irina1246 [14]

Answer:

\frac{21}{8}

Step-by-step explanation:

Given: 3\frac{1}{8} - \frac{1}{2}

Let's changed that mixed number to an improper fraction. Now we get:

\frac{25}{8} - \frac{1}{2}

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

\frac{25}{8} - \frac{4}{8}

We can use \frac{4}{8} because it is equal to \frac{1}{2}. Now, all we need to do is subtract the numerators:

\frac{25}{8} - \frac{4}{8}=\frac{21}{8}
