Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:

This can be simplified as:

We replace s with "x + 4" and solve:

<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
Answer:

Step-by-step explanation:
Given
The attached rhombus
Required
The area
First, calculate the length of half the vertical diagonal (x).
Length x is represented as the adjacent to 60 degrees
So, we have:

Solve for x


So:


At this point, we have established that the rhombus is made up 4 triangles of the following dimensions


So, the area of the rhombus is 4 times the area of 1 triangle




Answer:
The shortcuts is
Divide number of units by 100
Step-by-step explanation:
From the question we are told that
insulin u-100 is 
From the data given above we see that
100 units of insulin u-100 is contained in 1 mL
So 1 unit of u-100 is contained in x mL
=> 
This means that a unit of insulin u-100 occupies 
So we can represent a single unit of insulin u-100 as 
Now if 1 unit of insulin u-100 is represented as 
Then y unites of insulin u-100 is represented as z
So

From the above calculation we can see that the shortcuts to convert u-100 insulin given in units, to mL is to divide number of units by 100
