Let A= {a,b,c,d,e} and let B= {1,2,3,4,5} determine n(AxB)
n(AxB) = 25
Step-by-step explanation:
AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.
Given
A = {a,b,c,d,e}
B = {1,2,3,4,5}
The number of elements for Cartesian product of two sets is determined by:
[tex]n(AxB) = n(A) * n(B)[/tex]

The factored form of the expression −1.5w+7.5 is −1.5(w-5), since −1.5 is the common factor for both terms in the expression.
Explanation:The factored form of the expression −1.5w+7.5 can be found by factoring out a common factor. The common factor in this expression is −1.5, as both terms in the expression can be divided by −1.5.
Factoring out −1.5, we get:
−1.5w + 7.5
= −1.5 (w) + −1.5 (-5)
= −1.5 (w - 5)
Therefore, the factored form of −1.5w+7.5 is −1.5(w−5).

Step-by-step explanation:
which equation represents grants path?
A. y=2-4x
B. y=4-x/2
C. y=6-x/4
D. y=8-2x
Answer:
C.
Step-by-step explanation:
recall that the point-slope form of a linear equation is given by
y = mx + c
Rearranging so that it is in the same form as the answer choices, we get
y = c + mx
where m is the slope and c is the y-intercept
we note the following observations
1) The line goes from top left to bottom right, this means that the slope is negative, hence m has to be negative. (in our case, all the choices have negative x)
2) The line crosses the y-axis at y = 4, this means the y-intercept is 4 and hence c = 4.
If we look at the choices, only choice B satisfies both observations (that m is negative and c = 4)
Answer:
B)

What is the sum of the EXTERIOR angles of an octagon?
Answer:
A rule of polygons is that the sum of the exterior angles always equals 360 degrees. Since it is a regular octagon, so each of the interior angles of octagon are equal. ((n-2)*180)/n where n is the number of sides of the polygon.for example in case n=8 for an octagon, so we get:
((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees.
Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.
And since there are 8 exterior angles, we multiply 45 degrees * 8 and we get 360 degrees.
This technique works for every polygon, as long as you are asked to take one exterior angle per vertex.
The sum of the exterior angles of any polygon, including an octagon, is always 360 degrees. This is true regardless of the polygon's number of sides, because when one traces around the polygon, the point will have made one full revolution, or 360 degrees.
Explanation:
In mathematics, the sum of the exterior angles of any polygon, not just an octagon, is always 360 degrees. This applies regardless of the number of sides the polygon has. The concept comes from observing how a point moves as one traces around the polygon: during the complete circuit, it will have made exactly one full revolution, which is 360 degrees in total. Just as a circle consists of 360 degrees, this concept applies to polygons and their exterior angles as well.

Sales Gi sells televisions. He earns a fixed amount for each television and an additional $ 20 if the buyer gets an extended warranty. If Gi sells 18 televisions with extended warranties, he earns $ 1 ,260. How much is the fixed amount Gi earns for each television? PLZZ HELP :)
Answer:
$50
Step-by-step explanation:
Simple math
Extended warranty don’t count so gotta take that out that’s be 20x18=360 1260-360=900 now divide 18 tvs from that and u get 900/18=50
To determine the fixed amount Gi earns for each television, a simple algebraic equation is set up and solved to find that he earns $ 50 per television without the extended warranty.
Explanation:To solve for the fixed amount Gi earns for each television without the extended warranty, we can set up an equation.
Let's call the fixed amount $F. Each television with an extended warranty earns Gi an additional $ 20, so for each of those televisions, he earns $F + $20. If he sells 18 televisions with extended warranties,
the total amount he earns can be represented by 18($F + $ 20), which equals $ 1,260 according to the question.
We can create the following equation to find the fixed amount $F:
18($F + $ 20) = $ 1,260
To solve for $F, divide both sides of the equation by 18:
$F + $ 20 = $ 70
Then, subtract $ 20 from both sides to isolate $F:
$F = $ 50
So, the fixed amount Gi earns for each television is $ 50.
Stephanie works as a waitress and earns $4.50 an hour. Stephanie's last paycheck was $150. She earns $60 in tips in addition to her hourly pay. Write an equation the represents this situation. How many hours did Stephanie work? Paragraph Please!!!!!!!!!!!
Stephanie worked for 33 hours 20 minutes.
Explanation:
Step 1; Stephanie works and earns $4.50 an hour. Her last paycheck was for $150. So to find the number of hours she has worked we divide the total money earned by the money she earns every hour.
Total hours worked = Total money earned / Money earned for an hour
= $150 / $4.50 = 33.33 hours.
Step 2; We need to convert the 33.33 hours into hours and minutes.
We multiply the 0.33 hours with 60 to convert it into minutes. 0.33 × 60 = 20 minutes. So Stephanie worked for 33 hours and 20 minutes to get her last paycheck.
Answer:
20 hours
Step-by-step explanation:
She receives $60 regardless of the number of hours she works for. Per hour, she earns $4.50. In t hours, she earns:
60 + 4.50t
For some t, the total is $150
150 = 60 + 4.50t
90 = 4.50t
t = 20

answer is (-4,17)
To solve the given system using the substitution method, solve the second equation for y, substitute into the first equation, and solve for x. Substituting x back into the expression for y gives the solution x = 2 and y = 5.
Explanation:To solve the system of equations using the substitution method, we have to express one variable in terms of another from one of the equations and then substitute it into the other equation. For the given system of equations:
2x - 3y = -112x + y = 9First, we solve the second equation for y:
y = 9 - 2x
Now we substitute this expression for y into the first equation:
2x - 3(9 - 2x) = -11
2x - 27 + 6x = -11
8x - 27 = -11
8x = 16
x = 2
After finding x, we can substitute x back into y = 9 - 2x to find the value of y:
y = 9 - 2(2)
y = 9 - 4
y = 5
The solution to the system of equations is x = 2 and y = 5.

Answer:
1. a. 72/100 = 324/x
72x = 32,400
b. 450 students are in Math 6
2. a. o = 3b
b. o = 3 pounds
3. a. Most popular animals:
A. Dogs - 67%
B. Cats - 20%
C. Other - 8%
D. None - 4%
E. Horses - 1%
b. 20 students
c. If 75 students have cats, the estimate of 250 students isn't correct.
The actual number of students interviewed is 375.
Step-by-step explanation:
1. a. Let's use the following equation to solve the question:
x = Students that are in Math 6
72/100 = 324/x
72 * x = 324 * 100
72x = 32,400
b. Let's solve the equation, as follows:
x = 32,400/72
x = 450
450 students are in Math 6
2. a. The equation is:
o = 0.15 *20b
o = 3b
where, o = weight of oats in pounds and b = number of dog food bags
b. Let's find out the weight of the oats in one dog food bag, using our equation:
o = 0.15 *20b
o = 0.15 *20 * 1
o = 3 pounds
3. a. Most popular animals:
A. Dogs - 67%
B. Cats - 20%
C. Other - 8%
D. None - 4%
E. Horses - 1%
b. If 250 students were interviewed, the 8% who answered "other" are:
8% of 250 = 0.08 * 250 = 20 students
c. If 75 students have cats, the estimate of 250 students isn't correct.
The 20% of 250 is 50, not 75.
0.2 * 250 = 50
The actual number of students interviewed is:
x = Actual number of students interviewed
75/x = 20/100
20x = 7,500
x = 7,500/20
x = 375
The actual number of students interviewed is 375.
