Find the area of following rhombuses. Round your answers to the nearest tenth if<br> necessary.
polet [3.4K]

Answer:

Area =55.4ft^2

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:

\tan(60) = \frac{4\sqrt 3}{x}

Solve for x

x = \frac{4\sqrt 3}{\tan(60)}

\tan(60) = \sqrt 3

So:

x = \frac{4\sqrt 3}{\sqrt 3}

x = 4

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

Base = 4\sqrt 3

Height = 4

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

Area = 4 * \frac{1}{2} * Base * Height

Area = 4 * \frac{1}{2} * 4\sqrt 3 * 4

Area =2 * 4\sqrt 3 * 4

Area =55.4ft^2

Please help... How many odd perfect squares are between 5 and 211?
frez [133]

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

  • 3² = 9
  • 5² = 25
  • 7² = 49
  • 9² = 81
  • 11² = 121
  • 13² = 169

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

Please help me because I don't understand how to do it.:)
lana66690 [7]

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
