86 × π = 86π
or
86 × 3.14 = 270.04
you can use both of them depends on what form the question is asking that ur answer be in
Answer:
770 per hour.
Step-by-step explanation:
<h3>{ 13, 9, 6} represent the sides of a triangle</h3>
<em><u>Solution:</u></em>
<em><u>Use the triangle inequality law</u></em>
The sum of the lengths of any two sides of a triangle must be greater than the third side
<em><u>Option A</u></em>
{13, 9, 6}
Also,
Thus, sum of length of any two sides is greater than third side
Therefore, { 13, 9, 6} represent the sides of a triangle
<em><u>Option B</u></em>
{12, 7, 20}
19 is not greater than 20
Therefore, {12, 7, 20} does not represent the sides of a triangle
<em><u>Option C</u></em>
{25, 50, 75}
75 is equal to 75
Therefore, {25, 50, 75} does not represent the sides of a triangle
Your equation is wrong
the first is suppoosed to be 3(45), you wrote 5(45) but it should be 3(45), it's 3 trips, not 5
the other part is right tho, it is 6h
so 3(45)+6h=303 is the right equation
remember, you can do anything to an equation as long as you do it to both sides
so first expand 3(45)
3(45)=135
135+6h=303
minus 135 both sides
6h=168
divide both sides by 6
h=28
the hourly rate is $28 per hour

Step-by-step explanation:
<h3>QUESTION-2:</h3>
we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is
divide both sides by 2
<h3>Question-1:</h3>
in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,
let our opp, hypo and be GH, 4√10 and 60° respectively
thus substitute:
recall unit circle:
cross multiplication:
simplify multiplication:
divide both sides by 2:
<h3>QUESTION-3:</h3>
Recall that, the sum of the interior angles of a triangle is 180°
therefore,
simplify addition:
cancel 150° from both sides
