Answer:
P x Q
Step-by-step explanation:
The Cartesian product of two sets P and Q can be written as,
P × Q.
What is set?Sets are groups of well-defined objects or components in mathematics. A set is denoted by a capital letter, and the cardinal number of a set is enclosed in a curly bracket to indicate how many members there are in a finite set.
Given:
P and Q are the two sets.
The Cartesian product of two sets P and Q can be written as,
P × Q.
For example,
if A = {1, 2} and B = {3, 4},
then the Cartesian Product of A and B is {(1, 3), (1, 4), (2, 3), (2,4)}.
Therefore, P × Q is the required expression.

A cheese shop has some bulk cheese in blocks measuring 30 cm x 20 cm x 8 cm. How much paper is needed to cover the block of cheese
Answer:
232cm
Step-by-step explanation:
A cheese usually has the shape of a cuboid.
Characteristics of a Cuboid
A cuboid is a convex polyhedronIt has 12 edgesIt has 8 facesIts base shape is a rectangleIt has 6 facesThe amount of paper that would be needed to cover the block of cheese can be determined by calculating the perimeter of the block of cheese which is shaped as a cuboid
Perimeter of a cuboid = 4 x (length + breadth + height)
4 x (30 + 20 + 8) = 232cm

Answer:
The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
Step-by-step explanation:
The statement describes an arithmetic progression, which is defined by following formula:
[tex]p(n) = p_{1}+r\cdot (n-1)[/tex] (1)
Where:
[tex]p_{1}[/tex] - First element of the sequence.
[tex]r[/tex] - Progression rate.
[tex]n[/tex] - Index of the n-th element of the sequence.
[tex]p(n)[/tex] - n-th element of the series.
If we know that [tex]p_{1} = 1[/tex], [tex]n = 2[/tex] and [tex]p(n) = 5[/tex], then the progression rate is:
[tex]r = \frac{p(n)-p_{1}}{n-1}[/tex]
[tex]r = 4[/tex]
The set of elements of the series are described by [tex]p(n) = 1 + 4\cdot (n-1)[/tex].
Lastly, if we know that [tex]n = 300[/tex], then the 300th term of the sequence is:
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 1197[/tex]
And the next three terms of the sequence are:
n = 5
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 17[/tex]
n = 6
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 21[/tex]
n = 7
[tex]p(n) = 1 + 4\cdot (n-1)[/tex]
[tex]p(n) = 25[/tex]
The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.

A. $3.45
B. $0.45
C. $3.15
D. $1.61
Answer:
Cost of 7 pound potato = $3.15
Step-by-step explanation:
Given:
Cost of 5 pound potato = $2.25
Find:
Cost of 7 pound potato
Computation:
Cost of 1 pound potato = 2.25 / 5
Cost of 1 pound potato = $0.45
Cost of 7 pound potato = 7 x Cost of 1 pound potato
Cost of 7 pound potato = 7 x 0.45
Cost of 7 pound potato = $3.15

Answer:
x=5/6 and y=8/5
(5/6 , 8/5)
Step-by-step explanation:
You can use the elimination method! The point of this method is to add or subtract one equation from the other, multiplying them by constants if necessary, to cancel out one variable so you can solve for the other. Then, you can plug the value you got for your solution into either equation to solve for the other. I'll demonstrate.
Look at the two equations and the coefficients of both variables. You have 12x and -6x -- 6*2=12, so this is perfect. (You could also eliminate the y because 5*3=15, but I'll show you by eliminating the x instead.)
Here's what that looks like:
(-6x+1y=3)2
-12x+10y=6
So we just multiplied the second equation by 2 on both sides. Let's see how that helps us.
12x+15y=34
-12x+10y=6
If we add the two equations now, x will be canceled out and we can solve for y.
12x+15y=34
+(-12x+10y=6)
___________
0x+25y=40
25y=40
0x=0, so we can get rid of the x. Now, we need to solve for y.
25y=40
y=40/25
You probably know how to simplify fractions, so divide both the numerator and the denominator by 5 to get y=8/5.
Now you can use this value in either equation and solve for x. I'll use the first. (This is called substitution.)
12x+15(8/5)=34
12x+3(8)=34 <-- What I did here is cancel out the 5 in the denominator with 15 to leave 3, because 5*3=15.
12x+24=34
12x=10
x=10/12
x=5/6 (Divide the numerator and denominator by 2.)
You can write your answer as a point, too. (5/6 , 8/5)

Answer:
15 cookies
Step-by-step explanation:
10 cookies is equivalent to 2 scoops of flour.
You need to find how many cookies they can make with just 1 scoop of flour.
So, to do that, you'd need to do 10/2, which is 5.
10 represents the number of cookies, and 2 represents the scoops of flour. (5 represents the number of cookies you can make with 1 scoop of flour.)
This will work with any certain amount of flour, just use the equation 5 times X, where X is the amount of flour.
In this certain problem, they gave us the scoops of flour.
Replace X with 3.
3 times 5 = 15.
15 cookies.
Convert 5pie/3 radians to degree measure
Answer:
300°
Step-by-step explanation:
That'd be 5pi/3 radians. Note that 3pi/3 radians corresponds to 180° and that 6pi/3 corresponds to 360°. Thus 5pi/3 is in Quadrant IV, meaning that the angle in degrees is between 270° and 360°.
The "radians to degrees" conversion factor is (180°/pi), and so
5pi/3 radians works out to:
5pi/3 · 180° 5· 180°
----------------- = ---------- = 300°

The Lawrence family went out to dinner. The
total amount of dinner was $53.89, and they
decided to add an 18% tip. How much did the
waitress receive for a tip from the Lawrence
family?
Answer: 9.70$
Step-by-step explanation: The equation is 53.89 * 0.18 = 9.7002 but, If you round to the nearest hundred it is 9.70$. Hope this helped!!!
The amount of tip waitress get from the Lawrence family is $63.5902.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
The total amount of dinner was $53.89.
Tip= 18%
So, the tip amount will be
= 53.89 x 18/100
= 53.89 x 0.18
= 9.7002
And, the total amount to pay
= 53.89+ 9.7002
= $63.5902
Hence, the amount of tip waitress get is $63.5902.
