Answer:
<h2>20 cm.</h2>
Step-by-step explanation:
We know that the permiter is defined as

Where
is the longest side,
is the smallest and
is the middle side.
If
then,
, where we need to find an expression for
using the law of cosines.

Replacing all expression, the perimeter is

Using a calculator, the perimeter is 20 units centimeters.
<span>Moores Family Paid = 6 dollars mores for skate rental
than the cotters did.
30 dollars = the total amount they paid for skate rentals.
Let Family Moore have the variable X
Let the Family Cotters have the variable Y
=> x = y + 6
=> y = 30 – 6 / 2
First, let’s solve the Y
=> Y – 30 – 6 / 2
=> Y = 24 / 2
=> y = 12
Now, let’s solve for X
=> X = y + 6
=> x = 12 + 6
=> X = 18

Answer:
x ≈ 8.3 ( to the nearest tenth )
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos41° =
=
= 
Multiply both sides by 11
11 × cos41° = x, thus
x ≈ 8.3

#3: Am group median: 25.5 Pm group median: 19
#4: Am group first Quartile = 16 Pm group first Quartile = 10
#5: Am group third Quartile = 30 Pm group third Quartile = 37
#6: see images
#7: Am group Interquartile Range = 14 Pm group Interquartile Range = 27
#8: Am group because its Interquartile gruop is smaller than the Pm group
