Find the perimeter of a rhombus the length of whose diagonals are 10 cm and 24 m.

Mathematics

Svet_ta [14]3 years ago

check the picture below.


recall that in a rhombus, both diagonals bisect each other, namely cut each other in equal halves and at right-angles, so we end up with 4 right-triangles.


now, the sides in a rhombus are all equal, thus the perimeter is 13+13+13+13.

How does a residential survey help buyers?
Gnoma [55]
<span>C) buyers are aware of the accurate measurements of the property. A residential survey is also known as a boundary survey and is used to determine the boundaries of a piece of property. It is generally required as part of the process of building new construction on a property to insure that the construction doesn't cross the property line and intrude on someone else's property. With this in mind, only option "C" reflects what a residential survey is.</span>

F(2)=20(1.25)^x<br> STEP BY STEP
Nezavi [6.7K]
F(2) = 20(1.25)^x

f(2) = 20(1.25)^2 - plug in 2 to x

f(2) = 20(1.5625) - calculate 1.25^2

f(2) = 31.25 - simplify

Suppose a company produces report indicates that the surveyed distance between two points is 1200 feet with a margin of error of
Otrada [13]
<h2>Hello!</h2>

The answers are:

MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft

<h2>Why?</h2>

Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.

We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:

MaximumDistance=ActualDistance+0.1feet\\\\MaximumDistance=1200feet+0.1feet=1200.1feet

MinimumDistance=ActualDistance-0.1feet\\\\MaximumDistance=1200feet-0.1feet=1199.9feet

Have a nice day!
