Answer:

36 units ⇒ Answer 1 is correct

Step-by-step explanation:

To find the perimeter of a triangle you have to simply add the 3 sides together.

They have given the lengths of three sides as follows.

9 , 12 , 15 units

Let us solve now.

Perimeter = 9 + 12 + 15

= 21 + 15

= 36 units

Hope this helps you :-)

Let me know if you have any other questions :-)

You are randomly selecting 3 cans of regular and diet cola, but assume that there are 6 cans of regular cola and 7 cans of diet

gayaneshka [121]

Answer:0.367

Step-by-step explanation:

Given

There are 6 cans of regular and 7 cans of diet cola

number of ways of selecting 2 regular colas and 1 can of diet cola is

$\Rightarrow ^6C_2\times ^7C_1$

The total no of ways of selecting 3 items out of 13 items is

$\Rightarrow ^{13}C_3$

Probability is

$\Rightarrow P=\dfrac{^6C_2\times ^7C_1}{^{13}C_3}=\dfrac{105}{286}\\\Rightarrow P=0.367$

Pls help solve question 3

Lelu [443]

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

so, the value of ab is 40
