Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A = ( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s² = 324
( divide both sides by
)
s² = 324 ( take the square root of both sides )
s = = 18
Thus
perimeter = 3 × 18 = 54 cm

Answer:
$189.32
Step-by-step explanation:
Add all of the numbers shown to the beginning balance to find the ending balance.
$92.19 -39.35 +49.76 +87.35 +9.97 -10.60 = $189.32
Tristan's balance at the end of the month was $189.32.
__
There should be no confusion. Money deposited into the account increases the balance by the amount deposited.
Money spent from the account decreases the balance by the amount spent.
Here, amounts deposited are given a plus sign (+); amounts spent are given a minus sign (-).

<em>Additional comment</em>
It can be tedious to enter these numbers correctly into a calculator. Many folks prefer a calculator that provides a "tape", a record of the amounts and operations the calculator uses in the computation. Alternatively, you can put the numbers in a spreadsheet and use the SUM function to do the addition for you. That, too, makes it easy to check that numbers have been entered correctly.
The attachment shows the calculation done in a spreadsheet.
Answer:
<h2>No, Given relation is not a function.</h2>Explanation:
We know that , if any vertical line cuts the given graph of relation at exactly one point, then the relation can be called as function.
From Given graph , we find that the vertical line through any point on x-axis greater than zero (ex : X = 5) cuts the graph at more than one point.
Hence, Given relation is not a function.
Hope this helps...
Good luck on your assignment...
