Answer:
[tex]xy(x + y)(x - y)[/tex]
Step-by-step explanation:
[tex] {x}^{3}y - x{y}^{3} [/tex]
Taking xy common ,
[tex] = > xy( {x}^{2} - {y}^{2} )[/tex]
We know that
[tex] {a}^{2} - {b}^{2} = (a + b)(a - b) [/tex]
So,
[tex] = > xy(x + y)(x - y)[/tex]
Find the value of x and y. Show all your work neat and
in order.
Answer:
x = 21°
y = 29°
Step-by-step explanation:
a) Solving for x
Note that:
(3x - 3)° and 60° are Alternate interior angles, and alternate interior angles are equal to each other, hence:
3x - 3 = 60° (Alternate interior angles)
Add 3 to both sides
3x - 3 +3 = 60 + 3
3x = 63°
x = 63°/3
x = 21°
b) Solving for y
Notes that:
(3x - 3)° and (4y + 4)° are Consecutive interior angles and the sum consecutive interior angles is 180°
3x - 3 + 4y + 4 = 180°
3x + 4y - 3 + 4 = 180°
3x + 4y + 1 = 180°
Note that x = 21
Hence
3(21) + 4y + 1 = 180°
63 + 1 + 4y = 180°
64 + 4y = 180°
Subtract 64 from both sides
64 - 64 + 4y = 180° - 64
4y = 116°
y = 116/4
y => 29°

Answer:
x ≈ 10.6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationship between trig functions and side of a right triangle. In particular, when the opposite side and hypotenuse are involved, the desired relation is ...
Sin = Opposite/Hypotenuse
For your triangle, this is ...
sin(62°) = x/12
x = 12·sin(62°)
x ≈ 10.6

Answer: 5:2
Step-by-step explanation:
Well, you are going to find a number they both divide by in this case it is 2
10/2=5
4/2=2
Now when rewriting your numbers make sure to put what comes first first
5:2
5 and 2 can not be divided evenly anymore so your final answer is 5:2

What is the difference of –96.43 – (–98.67)?
Answer:
2.24
Step-by-step explanation:
This problem can actually be changed from a subtraction problem to an addition problem. Two negative signs together make a positive.
So, the problem becomes:
-96.43
+ 98.67
Now, remember this phrase to help solve problems like this:
Same sides add and keep. Different signs subtract. Keep the sign of the higher number.

Answer:
Infinite number of solutions
Step-by-step explanation:
when you solve for V, you notice that the term in "v" goes away, and you end up with a true statement:
2 = 2
This is a true statement no matter what values the variable V has, so it is true for all possible (infinite) values of "v".

The graph shows the soulution
Answer:
B. (3, -2)
Step-by-step explanation:
The solution of the system of the equations given, can be determined using the graph. The coordinate of the point where the two lines of both equations intersect is the solution.
Both lines intersect at x = 3, when y = -2.
Therefore, the solution would be (3, -2).

A shoe store costs 1800 dollars a month to operate. The average wholesale cost of each pair of shoes is 25 dollars, and the average price of each pair of shoes is 65 dollars. How many pairs of shoes must the store sell each month to break even?
Answer: 45
Step-by-step explanation:
The store has to sell
45
pairs of shoes.
Explanation:
The store has a base cost of
$
1800
, the cost per pair of shoes is
$
25
. Each pair of shoes is sold for
$
65
, therefore the profit per pair of shoes is
$
65
−
$
25
=
$
40
The formula for calculating the amount that needs to be sold would look like this;
40
x
=
1800
To determine the value of
x
, we take this formula;
x
=
1800
40
x
=
45
Therefore, the store needs to sell
45
pairs of shoes to break even.

I don't really know but I believe it is:
Rounded to the nearest thousandth, the conditional relative frequency that an eleventh grader likes tennis is 69%.
ROunded to the nearest thousandth, the conditional relative frequency that a twelfth grader likes tennis is 51%.
Since 51% is less than 69%, a greater percent of eleventh grader like tennis.

Help 3/4× 2 1/4 plsss
Answer:
Step-by-step explanation:
3/4 x 9/4 = 1.6875 or 27/16
Answer:
1[tex]\frac{11}{16}[/tex]
Step-by-step explanation:
When multiplying mixed numbers, you would want to turn them into improper fractions first before evaluating.
[tex]\frac{3}{4}[/tex] × 2[tex]\frac{1}{4}[/tex] = [tex]\frac{3}{4}[/tex] × [tex]\frac{9}{4}[/tex]
Now you can just directly multiply the fractions (denominators with denominators and numerators with numerators)
[tex]\frac{3}{4}[/tex] × [tex]\frac{9}{4}[/tex] = [tex]\frac{27}{16}[/tex]
You know that is still an improper fraction, so you need to turn it back to a mixed number.
[tex]\frac{27}{16}[/tex] = 1[tex]\frac{11}{16}[/tex]
