Use the Pythagorean theorem to find z:
z = √(6^2 + 9^2)
z= √(36 + 81)
z = √117
z = 3√13 = 10.8
Use leg rule to find x:
x/6 = 6/9
Cross multiply:
9x = 36
Divide both sides by 9:
x = 36/9
x = 4
Use Pythagorean theorem to find y:
y = √(6^2 + 4^2)
y= √(36 + 16)
y = √52
y = 2√13 = 7.2

Answer:</h2>
We will use substitution to solve this system for x.
Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.
We now have our solution.
D. 
We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.
Since the equation checks out, our solution is correct.
The data type of the recorded data is a. nominal.
In statistics, there are different types of data which includes nominal, ordinal, ratio, and interval data.
For nominal data, they are mainly used for identification and classification of variables. or simply put, they are used for labelling variables and has no numerical value attached to them.
In the example given above, each recorded choice of each person in the group would be recorded as nominal data for the sake of classification. The photographs can be labelled using letters or assigned numbers. However, these numbers are merely for identification purpose.
Therefore, the data type recorded is a. nominal.

B and c are correct because you use divison and multiplication to get the right answer and the right answer is 99cm
Looking at the given question, we can find several important information's and based on thm we can easily calculate the amount after 10 years.
Principal amount = $550
Rate of interest per year = 3%
Number of years the amount is to be kept = 10 years
Now we get put these information's in the formula of finding amount of money kepy in simple interest.
Amount = P(1 + rt)
Where
p = principal amount
r = rate of interest
t = Time
Then
Amount = 550[1 + (3/100) * 10)]
= 550 [1 + 3/10]
= 550 * (13/10)
= 55 * 13
= 715 dollars
So the total amount in my account will be $715
