Answer:
They started shopping for cloths at 11:45 AM
Step-by-step explanation:
First of all we have to calculate the whole time that they spent in the mall starting from shopping.
They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:
[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]
as 30 minutes is equal to half hour so we used 0.5 in place of it.
Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.
[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]
Hence,
They started shopping for cloths at 11:45 AM

please help me, solve for n
Answer:
The value of n will be:
[tex]n=\frac{89}{4}[/tex]Step-by-step explanation:
Given the expression
[tex]\frac{n}{2}-8^{-1}=11[/tex]
Apply the exponent rule:
[tex]a^{-1}=\frac{1}{n}[/tex]so the expression becomes
[tex]\frac{n}{2}-\frac{1}{8}=11[/tex]
Add 1/8 to both the sides
[tex]\frac{n}{2}-\frac{1}{8}+\frac{1}{8}=11+\frac{1}{8}[/tex]
[tex]\frac{n}{2}=\frac{89}{8}[/tex]
[tex]n=\frac{89}{4}[/tex]
Therefore, the value of n will be:

Answer please
Answer:
(a) [tex]3x^2 + 27y^2 + z^2 - 18xy + 6 \sqrt{3} yz -2 \sqrt{3} zx[/tex]
this can be written as
[tex](-x\sqrt{3})^2 + (y3\sqrt{3})^2 + (z)^2 +2 ( -x\sqrt{3} )( y3\sqrt{3}) + 2( y3\sqrt{3})(z) + 2(z)( -x\sqrt{3})[/tex]
which is equivalent to
[tex]a^2+ b^2 + c^2 + 2ab + 2bc + 2ac = (a+b+c)^2[/tex]
[tex](-x\sqrt{3} + y3\sqrt{3} + z)^2 = (-x\sqrt{3} + y3\sqrt{3} + z)(-x\sqrt{3} + y3\sqrt{3} + z)[/tex]
(b)[tex]27 x^3 + 125y^3[/tex] = [tex](3x)^3 + (5y)^3[/tex]
which is same as [tex]a^3 + b^3 = (a+b)(a^2 +b^2 -ab)[/tex]
= [tex](3x + 5y)(9x^2 + 25y^2 -15xy)[/tex]
(c) [tex](2a - 3b + c )^2[/tex] = (2a -3b +c)(2a -3b+c)
(d) [tex]a^3 + b^3 + 125 c^3 - 15 a b c[/tex]
this is same as
[tex]a^3 + b^3 +c^3 - 3abc[/tex] = [tex](a+b+c)( a^2+b^2+c^2 -ab-bc-ac)[/tex]
= [tex](a + b + 5c)(a^2+b^2 +25c^2 -ab -5bc -5ac)[/tex]
(e) [tex](x - 1/x y)^3[/tex] = [tex](x - 1/xy)(x - 1/xy)(x - 1/xy)[/tex]
(f) [tex]x^4 y^4 - x y64^4 = xy( x^3y^3 - 64^4) = xy( x^3y^3 - (256)^3) \\ = xy( xy - 256 )(x^2y^2 + 65536 + 256xy)[/tex]
(using the property of [tex]a^3 -b^3 = (a-b)(a^2+b^2 +ab)[/tex] )
(g) [tex]8x^3 - (2x - y)^3 = (2x)^3 - (2x-y)^3 \\ = (2x - 2x + y)(4x^2 + (2x-y)^2 + 2x(2x-y))\\ = y(8x^2 + y^2 -6xy +4x)[/tex] using the same property above
(h)
[tex]a^6 -b^6 = (a^2)^3 - (b^2)^3 = (a^2-b^2)( a^4+b^4 +a^2b^2)\\ = (a-b)(a+b)( a^4+b^4 +a^2b^2)[/tex]

A line goes through points (0.5, 50) and (2, 70). Which graph has a trend line with the least slope? Math Scores vs. Hours Spent Studying Science Scores vs. Hours Spent Studying Spelling Scores vs. Hours Spent Studying History Scores vs. Hours Spent Studying
Answer:
The answer is C)Spelling Scores vs. Hours Spent Studying
Step-by-step explanation:
This is the answer because if you look at all of the other options, then you will see that they have a steeper slope, you could also calculate and find for slope if u are still unsure :) hope this helps
The graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph
What is the slope of a line?The slope of a line is the quotient of the change in the vertical values to the corresponding horizontal values
Check below on how the trend line with the least slope can be determined
From the question, we have:
Line 1: (2.5, 60) and (3.5, 70)Line 2: (0.5, 40) and (3.5, 50)Line 3: (0.5, 80) and (4.5, 90).Line 4: (0.5, 50) and (2, 70).The slope (m) is calculated using:
m = (y₂ - y₁)/(x₂ - x₁)
So, we have:
m₁ = (70 - 60)/(3.5 - 2.5) = 10m₂ = (50 - 40)/(3.5 - 0.5) = 3.3m₃ = (90 - 80)/(4.5 - 0.5) = 2.5m₄ = (70 - 50)/(2 - 0.5) = 13.3The line 3 has the least slope
i.e. m₃ = 2.5
Hence, the graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph

There 18 rows of seats in the auditorium there are 24 seats in each row how many seats are in the auditorium
Answer:
432 seats
Step-by-step explanation:
Since 24 seats = 1 row, all we have to do is multiply 24 by 18, since there are 18 rows of seats. This would give us 432, which is the total number of seats in the auditorium.

favorite kind of movie. Select the appropriate values to
complete the model to find the fraction of students that
prefer comedy or action movies.
What fraction of the students who were surveyed prefers
comedy or action movies?
Answer:
71/100
Step-by-step explanation:
Action 29 plus comedy 42 equals 71 and if you add action, comedy, drama, and horror you get your denominator of 100
Fraction of the students is 71/100 who were surveyed prefers comedy or action movies.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
We have to given that;
Number of students who prefer action = 29
Number of students who prefer comedy = 42
Here, Total students = 100
Hence, Fraction of the students who were surveyed prefers comedy or action movies is,
⇒ 29/100 + 42/100 = 71/100

Which algebraic expression means "four less than three times a number"
Answer:
3x-4

Find the perimeter of the figure if the following is true:
A= x^2
B= 4x + 8
C= 2x^2
D= x
The perimeter of a figure is the distance around the outside of the figure. To find the perimeter of this figure, we need to add the lengths of all sides. This is:
P = A + B + C + D
P = x² + 4x + 8 + 2x² + x
P = 3x² + 5x + 8
The perimeter is 3x² + 5x + 8.

Answer:B
Step-by-step explanation:
The new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).
What is dilation of a figure?
A dilation is a transformation that enlarges or reduces a figure in size.
Given is figure [A] as shown in the figure which is dilated three times the size and is reflected across the y-axis.
Given are the coordinates of the triangle as -
(-2, 1), (-6, 1) and (-2, 6)
When the image is dilated by K, then each coordinate will become -
(x, y) = (Kx, Ky)
Therefore, the new coordinates will be -
(-6, 3), (-18, 3) and (-6, 18)
Now, in reflection across the y - axis, the coordinates will become (-x, y) from the coordinates (x, y).
Therefore, the final coordinates will be -
(6, 3), (18, 3) and (6, 18)
Therefore, the new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).

Slope of dotted/dashed line: -3
Slope of Reflection line: 0.25
Equation of Reflection line: y = 0.25x - 2
Step-by-step explanation:
Slope of dotted line: rise/run. So 3/1 = 3. It is a negative slop because of the way it is facing ( \ ).
Slope of reflection line: rise/run. So 1/4 = 0.25. It is a positive slope ( / ).

y = 0.25x - 2
Find the sum of the finite geometric series
6 - 4 + 8/3 - 16/9 + 32/17
Answer:
The sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416
Step-by-step explanation:
We need to find the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17
The formula used to find sum of geometric series is [tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]
where a is 1st term, n is number of terms and r is common ratio
so, in the given geometric series 6 - 4 + 8/3 - 16/9 + 32/17 we have
First Term a=6
Common ratio r= -0.6
Number of terms n= 5
Putting values in formula to find sum of given geometric series
[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_n=\frac{6(1-(-0.6)^5 )}{1-(-0.6)}\\S_n=\frac{6(1-(-0.07776))}{1+0.6}\\S_n=\frac{6(1+0.07776)}{1.6}\\S_n=\frac{6.46656}{1.6}\\S_n=4.0416[/tex]
So, the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416

The solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2
The correct answers are option (A) and option (E)
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
What is solution to equations?"It is a value or a set of values, when substituted for the unknowns, the equation becomes true."
For given question,
We have been given the graph of a quadratic function f(x) and an absolute value function g(x).
We need to find the x-values that are approximate solutions to the equation f(x) = g(x).
To solve the equation f(x) = g(x), we look for the points where the graphs of f(x) and g(x) intersect.
The intersection point of f(x) = g(x) appears to be at point which lie in the second quadrant and the x-value lie between -2 and -4.
Also, the second intersection point lie in the fourth quadrant where x value is in between 4 and 6.
So, the solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2

Step-by-step explanation:
X symbolizes how many he is buying plus the extra 12 dollars
Answer:
5x+12=y
Step-by-step explanation:
Y represents the amount of money spent.
if x represents the amount of one book and Bob bought 5 books than you have to multiply the amount of one book by five to get the amount spent on all the books. Thus getting 5x
You need an equation to find how much money spent total. Thus adding $12 because Bob also bought a DVD for $12.
