Answer:
1. The fraction is 11/9
Step-by-step explanation:
You didn't specify which ones you need help with so I'm answering the first one for you.
let x=1.2 —equation 1
10x=12.2 —equation 2
subtract equation 1 from 2
10x-x=12.2-1.2
9x=11
x=11/9
-3 8/3 = -11/3
so
(-11/3) x (6/5)
= (-11) x (2/5)
= - 22/5
= - 4 2/5
hope it helps
Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question:
What is the volume of this triangular prism?
Base length = 22.4 cm
Height = 18.1 cm
Length = 28 cm
A) 313.6 cm3
B) 506.8 cm3
C) 5,676.16 cm3
D) 11,352.32 cm3
Answer:

Step-by-step explanation:
Given:
The base of the prism is triangular with base length equal to 22.4 cm and height 18.1 cm. The length of the prism is 28 cm.
The volume of a triangular prism is defined by the formula:

Here, the base is triangular and the area of a triangle is:

Therefore, the volume of the triangular prism is given as:

Now, plug in the given values and solve for the volume 'V'.

Therefore, the correct answer is the third option.
