In the diagram, ΔJKL ~ ΔMNO. What is the length of the side KL?

A) 3.3
B) 6
C) 7.5
D) 10

Answers

Answer:

Step-by-step explanation:

If Triangle MNO has the length of the side NO as 5, then multiply that by 1.5 and that will give you 7.5 as the length of side KL. Hope this helps you out!

Given that ΔJKL and ΔMNO are similar triangles, therefore KL is: C. 7.5.

What are Similar Triangles?

For any two or more triangles that are similar, their corresponding sides are proportional to each other, which means their ratio is equal.

Given that ΔJKL ~ ΔMNO, therefore:

KL/NO = JK/MN

Plug in the values

KL/5 = 3/2

Cross multiply

KL = (3 × 5)/2

KL = 7.5

Therefore, given that ΔJKL and ΔMNO are similar triangles, therefore KL is: C. 7.5.

Answer:

8:36 a.m.

Step-by-step explanation:

To solve this, first we need to calculate the lowest common multiple of 9 and 12.

Multiples of 9 = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108.

Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120.

Here, the lowest common multiple = 36

Therefore, we will add 8.00am plus 36 minutes. This will be:

= 8:00 a.m + 36 minutes

= 8.36 am

The time that the basic bowl and the gigantic bowl are first produced together is 8.36 am.

The answer to that would be 3/8

Answer:

I got 11/12

Step-by-step explanation:

Because you would take 2/3 × 1/4

They don't have the same denominators so you have to find a multiple. 12 is a multiple of both 3 and 4. In order to get a denominator of 12 for 2/3 you would have to multiply 3 by 4 and 2 by 4 leaving you with 8/12. Then you would have to multiply 1 by 3 and 4 by 3 leaving you with 3/12. Then you add them giving you 11/12. Hope this helps
