In MON, J, K, and L are midpoints. If JL = 11, LK = 13, and ON = 20, and JL || MN, LK || MO, and JK || ON, what is the length of

In-s [12.5K]

Answer:

The lengths of MN is 22 units, MO is 26 units and JK is 10 units

Step-by-step explanation:

A line segment joining the mid-points of two sides in a triangle is parallel to the third side and equal to half its length

In Δ MON

∵ J, K, and L are mid-points

∵ JL // MN and LK // MO

∴ L is the mid-point of ON

∴ J is the mid-point of MO

∴ K is the mid-point of MN

∵ J, L are the mid-points of MO and ON

∵ JL is opposite to MN

→ By using the rule above

∴ JL = $\frac{1}{2}$ MN

∵ JL = 11 units

∴ 11 = $\frac{1}{2}$ MN

→ Multiply both sides by 2

∴ 22 = MN

∴ MN = 22 units

∵ K, L are the mid-points of MN and ON

∵ KL is opposite to MO

→ By using the rule above

∴ KL = $\frac{1}{2}$ MO

∵ KL = 13 units

∴ 13 = $\frac{1}{2}$ MO

→ Multiply both sides by 2

∴ 26 = MO

∴ MO = 26 units

∵ J, K are the mid-points of MO and MN

∵ JK is opposite to ON

→ By using the rule above

∴ JK = $\frac{1}{2}$ ON

∵ ON =20 units

∴ JK = $\frac{1}{2}$ (20)

∴ JK = 10 units

∴ The lengths of MN are 22 units, MO is 26 units and JK is 10 units

Explain why rationalizing the denominator does not change the value of the original expression

anzhelika [568]

Rationalizing is just simpllifying, so the simplified value has the same value as the original expression.

Hi! I'm happy to help!

To solve this problem, we need to divide the recipe amount in 1/6 amounts. So, we will do a fraction division problem like this:

15 $\frac{1}{6}$ ÷ $\frac{1}{6}$

This problem is hard to do with mixed numbers, so we need to turn 15 $\frac{1}{6}$ into an improper fraction. To do that we need to multiply 15 by 6, because that is our denominator, then add the extra $\frac{1}{6}$ .

(15×6)+1

90+1

So, our improper fraction would be $\frac{91}{6}$ , now, let's solve.

$\frac{91}{6}$ ÷ $\frac{1}{6}$

It is difficult to do division problems on their own, so we can change this into an easier problem. We can do the inverse operation and turn this into multiplication. We do this by changing it to multiplication (obviously), then flip the second fraction.

$\frac{91}{6}$ × $\frac{6}{1}$

Now, we just multiply the top by the top, and bottom by the bottom.

$\frac{546}{6}$

We could end it here, but we want a whole number, so, we simplify the number by dividing both the top and bottom by 6.

$\frac{91}{1}$

Anything over 1, is just a whole number

91.

Therefore, the recipe should require 91 uses of the 1/6 cup.

I hope this was helpful, keep learning! :D
