Answer:
Yes, The commutative property of multiplication is: a × b = b × a. In short, in commutative property, the numbers can be added or multiplied to each other in any order without changing the answer. Let us see some examples to understand commutative property. Example 1: Commutative property with addition.
No, the equation 9 x 7 = 7 x 9 does not demonstrate the commutative property of multiplication.
The commutative property of multiplication states that the order of the numbers being multiplied does not affect the result; you can switch the order, and the product will remain the same.
In the given equation, both sides evaluate to 63 (9 x 7 = 63 and 7 x 9 = 63), so it might appear to satisfy the commutative property at first glance. However, this equation represents a single instance where the numbers used happen to have the same product. The commutative property should hold true for all pairs of numbers, which is not the case here.
For example, switching the order for 3 x 5 and 5 x 3 results in different products (3 x 5 = 15 and 5 x 3 = 15). Since the equation 9 x 7 = 7 x 9 does not hold true for all pairs of numbers, it does not illustrate the commutative property of multiplication.

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Ok so since this is an area question we should begin with writing the correct formula for it. This says it's rectangular pool so we'll be using our rectangle formula, which is...
[tex]A=lw[/tex]
Now we plug in what we know...
[tex]length=30\frac{1}{3} \\width=12\frac{1}{2}[/tex]
Now we solve...
[tex]A=lw\\A=(30\frac{1}{3})(12\frac{1}{2})\\A=379\frac{1}{6}[/tex]
So the area is.... [tex]379\frac{1}{6}[/tex] feet ²
or if you want an improper fraction....[tex]\frac{2275}{6}[/tex] feet²
or a decimal... [tex]379.1666667=379.17[/tex] feet².
at the movies, la quinta paid for drinks and popcorn for herself and her two children. she spend twice as much on popcorn as on drinks. if her total bill came to $17.94, how much did she spend on drinks and how much did she spend on popcorn?
Answer:
Step-by-step explanation:
let the amount spent on popcorn be x and amount spent on drinks be y
If the total bill paid is $17.94, then x+y = $17.94
If she spend twice as much on popcorn as on drinks, then y = 2x
Substitute y = 2x into the original equation
x+y = $17.94
x + 2x = $17.94
3x = $17.94
x = $17.94/3
x = $5.98
Since y = 2x
y = 2($5.98)
y = $11.96
Therefore she spent $5.98 on popcorn and $11.96 on drinks

Answer:
[tex]x = 2 \sqrt{2} i \: or \: x = - 2 \sqrt{2} i[/tex]
Step-by-step explanation:
• Add 7 to both sides.
[tex]3x {}^{2} - 7 + 7 = - 31 + 7[/tex]
• Simplify
[tex]3x {}^{2} = - 24[/tex]
• Divide both sides by 3
[tex] \frac{3x {}^{2} }{3} = \frac{ - 24}{3} [/tex]
• Simplify
[tex]x {}^{2} = - 8[/tex]
• Find the solution
[tex]x = \sqrt{ - 8} \: and \: x = - \sqrt{ - 8} [/tex]
• Simplify
[tex] \sqrt{ - 8} = 2 \sqrt{2i} [/tex]
[tex] - \sqrt{ - 8} = - 2 \sqrt{2i} [/tex]

Answer:
The volume of a prism is given by ...
V = Bh
Step-by-step explanation:
Here, the base is an equilateral triangle with side length 3 in. The area of such a triangle is given by
A = (√3)4*s²
where s is the side length.
Your triangular prism has a base area of ...
B = (√3)/4*(3 in)² = (9/4)√3 in²
so the volume is
V = ((9/4)√3 in²)(6 in)
V = (27/2)√3 in³
V ≈ 23.383 in³

Describe the five-step procedure to graphing logarithmic functions in your own words.
A logarithm function is a function that uses the log keyword, and it is the opposite of an exponential function
The procedure to graph a logarithm functionAssume the logarithm function is:
[tex]y = a\log_b(x - h) + k[/tex]
Where b represents the base of the function.
Step 1The first step is to determine the vertical asymptote of the function
The vertical asymptote of [tex]y = a\log_b(x - h) + k[/tex] is:
[tex]x = h[/tex]
Step 2The second step is to determine the x-intercepts
To do this, we set the function to 0
i.e. [tex]a\log_b(x - h) + k = 0[/tex]
Step 3The next step is to determine the y-intercepts
To do this, we set the x to 0
i.e. [tex]y = a\log_b(0- h) + k[/tex]
Step 4The next step is to plot the vertical asymptote, the intercepts and few points on the graph
Step 5Lastly the points that were plotted on the graph must be connected

Please... Solve this: the bearing of a tree from a house is 295°. Find the bearing of the house from the tree.
Given parameters:
Bearing of the tree from the house = 295°
Unknown:
Bearing of the house from the tree = ?
Solution:
This is whole circle bearing problem(wcb). There are different ways of representing directions from one place to another. In whole circle bearing, the value of the bearing varies from 0° to 360° in the clockwise direction.
To find the back bearing in this regard, simple deduct the forward bearing from 360°;
Backward bearing = 360° -295°
= 65°
The bearing from house to the tree is 65°
