The value of each letter in the given magic square is a = 30, b = 6 , c = 18 and d = 4.
What is a magic square?A magic square is one that has several different integers placed in such a way that the sum or total of the numbers is the same on all of the diagonals, as well as in every row, column, and major diagonal.
Given:
A magic square where all rows, columns, and diagonals sum to the same number.
Sum of the numbers in the diagonal of the magic square,
5 + 17 + 29 = 51
In the first row, the sum of numbers will also be 51
5 + a + 16 = 51
a = 51 - 21 = 30
Similarly, the sum in the first column
5 + 28 + c = 51
c = 51 - 33 = 18
And the sum in the last row,
c + d + 29 = 51
Putting the value of c, we get
18 + d + 29 = 51
d = 51 - 47 = 4
Now to find the value of b the sum of the last column,
16 + b + 29 = 51
b = 51 - 45 = 6

Segment RS is rotated 90 counterclockwise about the origin and then reflected over the y-axis. The resulting segment R"S" has coordinates R" (3,2) and R" (6,-5) . What are the coordinates of the segment RS ?
The coordinates of RS are R(2, 3) and S(-5, 6)
What is rotation?A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
Given:
Segment RS is rotated 90 counterclockwise about the origin
So, When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x).
Also, the coordinates are reflected over y- axis.
So, The coordinates of RS before reflection over y- axis is
R(-3, 2) and S(-6, -5)

Or $0.15
Or $0.20
Or $2.40
Or $3.20
Answer:
Second option $0.2

First we can convert 3/8 pounds to oz
since 16oz is in 1 pound
so 3/8 pound will be
3/8*16=6 oz
Then to find unit price per oz
we just take the total cost $1.20 divide by 6

Ryan has two jobs. He earns $9 per hour for x hours babysitting his cousins and he earns $18 per hour for y hours working at the coffee shop. Ryan will work both jobs. He is able to work no more than 10 hours a week, due to school commitments. Ryan wants to earn at least $72 a week, working a combination of both jobs. A write a system of inequalities that can be used to represent the situation.B. Graph these inequalities C. Determine and state one combination of hours that will allow Ryan to earn at least $72 per week while working no more than 10 hours
Let x and y be the number of hours Ryan works on each job respectively. He can work no more that 10 hours a week, it means that the sum of x and y must be less than or equal to 10:
[tex]x+y\le10[/tex]He also need to earn at least $72 a week, which means that the sum of 9 times x and 18 times y must be greater than or equal to 72:
[tex]9x+18y\ge72[/tex]The system of inequalities is:
[tex]\begin{gathered} x+y\le10 \\ 9x+18y\ge72 \end{gathered}[/tex]To graph these inequalities, we have to graph the boundary lines which are x+y=10 and 9x+18y=72, and then shade the region depending on the inequality. For the first inequality which is a less than or equal to, the shaded region must be under the boundary line (which is a continuous line) and for the second one, the shaded region must be above the boundary line (which is also continous).
In this case we only can take the solutions that have positive values of x and y, since Ryan can't work a negative number of hours. For example, one combination that will allow Ryan reach his goal is 5 hours as babysitter and 5 hours at the coffee shop.

the length of a rectangle is four times it's width. if the perimeter is at most 106 centimeters, what is the greatest possible value for the width?
Lenght of a rectangle: L
Widht of the rectangle: W
Perimeter of the rectangle: P
length of a rectangle is four times it's width: L = 4W
Perimeter is at most 106: P <= 106
Perimeter is 2L + 2W: P = 2L + 2W
P <= 106
if we use the value of P = 2L + 2W, we can write:
2L + 2W <= 106
Since L = 4W, then we can write this equation:
2L + 2W <= 106
2(4W) + 2W <= 106
8W + 2W <= 106
10W <= 106
W <= 106/10 = 10.6
W <= 10.6
Therefore, the greatest possible value for the width is 10.6

Four times the difference of some number and 3 amounts to the quotient of 144 and 12.
Written as an equation
The equation that can be derived is [tex]4(x-3)=12[/tex]
Given
Four times the difference of some number and 3 amounts to the quotient of 144 and 12.
Let us say some number is x
Quotient of 144 and 12,
Quotient = [tex]\frac{144}{12}[/tex]
Quotient = 12
Four times the difference of x and 3 is as follows
[tex]4(x-3)[/tex]
Writing this in the form of an equation we get
[tex]4(x-3)=12[/tex]
Hence the equation is obtained, also solving the equation for x
[tex]4x-12=12[/tex]
[tex]4x = 24[/tex]
[tex]x=\frac{24}{4}[/tex]

Given A and B are vertical angles with m /A = 20x + 10 and m/B = 30x - 10.
What is x?
Answer:
to solve for x, you gotta make the two equations equal to each other then you can move the numbers to get the value of x
20x+10=30x-10
20x-30x=-10-10
-10x=-20
x=2
Answer:
x=2
Step-by-step explanation:
if m/A and m/B are equal, to find x, your equation would be 20x+10=30x-10. doing two step equations, you would substract 20x from both sides, making your equation look like 10=10x-10. then you would add 10 from both sides making your equation 20=10x. then you would divide 10x from both sides making x=2.

The average human heart beats 1.037 x 105 times per day. The approximate average mouse heart beats
1.008 × 10 times per day. On an average, how many beats more does the mouse heart beats in a day?
09.043 x 105
O 2.9 x 10¹
8.942 × 10¹
1.029 × 10²
On an average 9.043 [tex]\times10^{5}[/tex] beats more does the mouse heart beats in a day.
The average human heart beats = 1.037[tex]\times10^5[/tex] times per day.
The approximate average mouse heart beats = 1.008[tex]\times10^6[/tex] times per day.
We have to find the how many beats more does the mouse heart beats in a day.
Since we have to find the more heart beat of mouse comparing to the human heartbeats. So we subtract their heart beat.
The human heartbeats have [tex]10^5[/tex] while mouse heartbeats have [tex]10^6[/tex]. So we first equal the power of 10. After equal the power we can easily find the value of the more heart beat of mouse.
We can write,
The average human heart beats = 0.1037[tex]\times10^6[/tex]
Now,
The more heartbeats of mouse = average mouse heart beats − average human heart beats.
The more heartbeats of mouse [tex]= 1.008\times10^6-0.1037\times10^6[/tex]
The more heartbeats of mouse [tex]=(1.008-0.1037)\times10^{6}[/tex]
The more heartbeats of mouse = 0.9043[tex]\times10^{6}[/tex]
The more heartbeats of mouse = 9.043[tex]\times10^{5}[/tex]

What is described as the extrema of a function?Extremum, plural Extrema, any point in calculus where the value of a function is greatest (a maximum) as well as smallest (a minimum) (a minimum). Absolute and relative (or local) maxima as well as minima exist. At a relative maximum, the function's value is greater than its value at directly adjacent points, whereas at an absolute maximum, the function's value is greater than its value any other point in the interval of interest.For the state question,
The function is defined as; f(x) = 2/(3x-5).
To estimated the extrema of the function, first find the critical points.
Differentiate the function with respect to x suing division rule.
f(x) = 2/(3x-5).
f'(x) = 3/(3x-5)²
Now, put the function equals to zero.
f'(x) = 3/(3x-5)² = 0.
3 = 0
But, 3 ≠ 0
Thus, there is no critical point found for the function.
