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

The amount of interest to be paid by Destiny on the $1600 loan at 6% rate for 3 years is $288.00.
What is the amount of interest earned over the given time?Interest is simply the amount of money a lender or financial institution receives for lending out money or pays for receiving money.
The formula calculating simple interest is expressed as;
I = P × r × t
Where P is principal, r is rate and t is time.
Given the data in the question;
Principal P = $1,600Interest rate r = 6%Time t = 3 yearsInterest I = ?First, convert the rate from percent to decimal.
Rate r = 6%
Rate r = 6/100
Rate r = 0.06
Now plug the values into the formula and solve for I
I = P × r × t
I = $1,600 × 0.06 × 3
Interest I = $288.00
Therefore, the interest accumulated by Destiny is $288.00.

The area of a triangle is given by the formula:
[tex]\begin{gathered} A=\frac{b\cdot h}{2} \\ \text{ Where b is the base and} \\ h\text{ is the height of the triangle} \end{gathered}[/tex]From the information given you know that the measure of the height of the triangle EFG is 16 cm but the measure of the base of the triangle is unknown.
To find the measure of the base, you can first find the measure of the middle of the segment EG using the Pythagorean theorem, since the triangle formed by the vertices F, G, and EG/2 form a right triangle. Graphically,
The formula of the Pythagorean Theorem is
[tex]\begin{gathered} a^2+b^2=c^2 \\ \text{ Where c is the hypotenuse and} \\ a,b\text{ are the sides of the triangle} \end{gathered}[/tex]So, you have
[tex]\begin{gathered} a=16 \\ b=\frac{EG}{2} \\ c=20 \\ (16)^2+b^2=(20)^2 \\ 256+b^2=400 \\ \text{ Subtract 256 from both sides of the equation} \\ 256+b^2-256=400-256 \\ b^2=400-256 \\ b^2=144 \\ \text{ Apply square root to both sides of the equation} \\ \sqrt[]{b^2}=\sqrt[]{144} \\ b=12 \\ \text{ Then} \\ \frac{EG}{2}=12 \end{gathered}[/tex]Then, the measure of the segment EG, that is, the measure of the base of the triangle EFG is
[tex]\begin{gathered} \frac{EG}{2}=12 \\ \text{ Multiply by 2 on both sides of the equation} \\ \frac{EG}{2}\cdot2=12\cdot2 \\ EG=24 \end{gathered}[/tex]Finally, the area of triangle EFG will be
[tex]\begin{gathered} b=24\operatorname{cm} \\ h=16\operatorname{cm} \\ A=\frac{b\cdot h}{2} \\ A=\frac{24\operatorname{cm}\cdot16\operatorname{cm}}{2} \\ A=\frac{384\operatorname{cm}^2}{2} \\ A=192\operatorname{cm}^2\text{ } \end{gathered}[/tex]Therefore, the area of the triangle EFG is 192 square centimeters.

5. Devon is considering taking out a 7,000 loan. He went to two banks, Stevenson Trust Company offered him an 8-year loan with an interest rate of 8.6%First National Bank offered him a 5-year loan with an interest of 10%Which loan will have the lower interest over its lifetime ?
The loan from National bank will have lower interest over its lifetime.
Interest is the additional payment made by a borrower or deposit-taking financial institution to a lender or depositor at a predetermined rate over and above the principal sum (the amount borrowed).
Interest differs from any fees the borrower may be required to pay to the lender or another party.Interest contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward gained by risk-taking businessmen when revenue is made that surpasses all expenditures.The principal or the amount to be taken loan is $7000.
Let us consider each bank and find the interest to be owed from the loan.
Stevension trust :
Rate = 8.6% = 0.086
time = 8 years
Interest = principal × time × rate = 7000 × 8 × 0.086 = $ 4816
First national bank :
Rate = 10% = 0.1
Time = 5 years
Interest = 7000 × 5 × 0.1 = $3500
Hence the loan from national bank will have lower interest over its lifetime.

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).

The average human heart beats 1.037 x 105 times per day. The approximate average mouse heart beats

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]
Hence, on an average 9.043[tex]\times10^{5}[/tex] beats more does the mouse heart beats in a day.
