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:
12
Step-by-step explanation:
3x + y = 6
Multiply both sides by 2
6x + 2y = 12
Answer:
we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
Step-by-step explanation:
Let us check by taking squares
As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.
Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
Answer:
C Yes, 75+ 2.5*60 = 225
Step-by-step explanation:
The charges for the electrician
1st hour = 75
Additional hours 60
We have 3 1/2 hours of labor
The first hour is 75 dollars
3 1/2 - 1 = 2 1/2
There will be 2 1/2 hours at the 60 dollar rate
75 + 60 * 2.5 =
75 + 150
225
