Use the fact that 2 1/2 divide 1/8 =20 to find 2 1/2 divide 5/8

Tasya [4]

Answer:

Step-by-step explanation:

Given that $2\frac 1 2 \div \frac 1 8 =20$

$\Rightarrow \frac 5 2 \div \frac 1 8 =20$

$\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)$

Now, $2\frac 1 2 \div \frac 5 8$ $= \frac 5 2 \div \frac 5 8$ $=\frac 5 2 \times \frac 8 5$

This can be written as

$\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right)$ [as $\frac 8 5=\frac 8 1 \times \frac 1 5$ ]

$=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5$

$=20 \times \frac 1 5$ [ by using equation (i)]

Hence, $2\frac 1 2 \div \frac 5 8=4$

What is the length of the diagonal from vertex J to vertex L in the quadrilateral below?

liberstina [14]

Answer:

sqrt(170) or approximately 13.038

Step-by-step explanation:

We can use the Pythagorean theorem to find the diagonal since the diagonal makes a right triangle

a^2 + b^2 = c^2

We need to find the leg lengths

ML = 7 and MJ = 11

7^2 + 11^2 = JL^2

49+ 121 = JL ^2

170 = JL ^2

Take the square root of each side

sqrt(170) = JL

13.038 = JL
