PLEASE HELP me with the magic square
Fill in each slot in the square with variables a, b, c, d, and e, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the magic sum.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
row 1:a + b + (-5.6) = -3.9
row 2:c + (-1.3) + d = -3.9
row 3:3 + e + 0.02 = -3.9
column 1:a + c + 3 = -3.9
column 2:b + (-1.3) + e = -3.9
column 3:(-5.6) + d + 0.02 = -3.9
diagonal 1 (top left to bottom right):a + (-1.3) + 0.02 = -3.9
You will find
a = -2.62
b = 4.32
c = -4.28
d = 1.68
e = -6.92

Step-by-step explanation:
in the year 2005 a company made $6.6 million in profit for each consecutive year after that their profit increase by 9% how much would a companies profit be in the year 2009 to the nearest 10th of $1 million
Answer:
$9.3 million
Step-by-step explanation:
Given that the company profit increases by 9% yearly from 2005.
Using the exponential growth formula;
A = P(1+r)^(t) .....1
Where;
A = final amount/value of profit
P = initial amount/value = $6.6 million
r = growth rate yearly = 9% = 0.09
t = time of growth in years = 2009 - 2005 = 4 years
Substituting the values;
A = 6.6(1+0.09)^(4)
A = 6.6(1.09)^(4)
A = 9.3164386 million
A = $9.3 million
The companies profit in the year 2009 to the nearest 10th of $1 million is $9.3 million

The diagram above shows
circle ABCD
with Centre E Quadrilateral EADC is a rhombus.
<BAE =<ECB=n and <ABC=m.
find
i) m
ii) n
Answer:
m = 60°n = 30°Step-by-step explanation:
Opposite angles D and E in the rhombus are congruent. The measure of arc ADC is the same as the measure of central angle AEC. The measure of arc ABC is twice the measure of angle AEC, so the measure of arc ABC is twice the measure of arc ADC.
This means that short arcs AB, BC and CA are all 120°. Inscribed angle ABC (angle m) is half that value, or 60°.
Likewise, the angle BAC is 60°. We know that angle EAD is supplementary to angle AEC, so is 180° -120° = 60°. Segment AC bisects this angle, so angle n is 60°/2 = 30° less than angle BAC.
angle m is 60°, angle n is 30°
A television is 28.5 inches wide and 16 inches long.
Using the Pythagorean Theorem, what is the length of the diagonal of the television, rounded to the nearest inch?
Answer:
33 in
Step-by-step explanation:
The Pythagorean theorem tells you ...
diagonal² = length² +width²
diagonal² = (16 in)² +(28.5 in)² = 1068.25 in²
diagonal = √(1068.25 in²) ≈ 32.684 in
The diagonal of the television is about 33 inches.
The ages of Rohit and James are in the ratio 2 : 5. In 9 years, the ratio of their ages will be 5 : 8. Find their present ages.
Answer:
Step-by-step explanation:
I don't say you have to mark my ans as brainliest but if you think it has really helped you then plz don't forget to thank me...
Answer:
Rohit is 6 years old
James is 15 years old
Step-by-step explanation:
Rohit : James 2 : 5
the difference between their units is 3
Now we add the 9 years
5 : 8the difference between their units should be 3 because they both age every year. the question was nice enough to give to same amount of units
Now we subtract James's original 'unit age' from his new one
8u - 5u = 3 uWe also need to make sure the difference between Rohit's original 'unit age' is 3
5u - 2u = 3uthis 3 units represent the 9 years that have passed
3 units = 9 yearsTo find James's age all we ahve to find is their original unit number
James (5 units) -> 3 × 5 = 15same for Rohit
Rohit (3 units) -> 3×3 = 9hence, Rohit's and James's ages are 9 and 15 respectivelywhat is the number that has the same value as l6l

The temperature on the 8th day was 4 °C.
What is the mean temperature for the first 8 days in January?
Answer:
4 degrees Celsius
Step-by-step explanation:
Since the mean is (total/amount), we can remake this to get That mean*amount=total. For the first 7 days, 4*7=28 for our total, and add that to the 8th day to get 32 for our total. 32/8=4 for our mean for the first 8 days of january

An above-ground swimming pool is 5 feet long, 4 feet wide, and 3 feet deep and is shaped like a rectangular prism. A rectangular prism has a length of 5 feet, height of 3 feet, and width of feet. If you use a net to find the amount of material used to make the pool, what faces are included in the calculation?
Answer:
the faces representing the sides and bottom of the pool are included
Step-by-step explanation:
Obviously, there is no pool material covering the top of the pool. Rather, it is "an open-top box", so the area of the faces of the box does not include the area of the top. The five faces other than the top face are included.

The percent markup on a video game is known to be 108% based on cost. If the seller paid $35 for one, then what would be the corresponding percent markup based on the sale price? (Round to the nearest tenth percent)
Answer: 48.1%
Step-by-step explanation:
The percent markup is defined as:
PM = (gross benefit/cost per unit.)*100%
We know that the cost per unit is $35
then we have:
108% = (gross benefit/$35)*100%
gross benefit = (108%/100%)*$35 = $37.8
This means that a game is selled by $35 + $37.8 = $72.8
Now we have:
Markup percent = (gross benefit/selling price)*100% = ($35/$72.8)*100% = 48.1%

"Eat For 10 Hours. Fast For 14. This Daily Habit Prompts Weight Loss, Study Finds"
This is the title of an NPR article about a 2019 study that recruited 19 overweight adults diagnosed with metabolic syndrome (elevated blood sugar, elevated cholesterol levels, high blood pressure). Participants were asked to restrict any eating to a period of just 10 hours each day. The study found a statistically significant reduction in body weight after 12 weeks of this eating pattern.
1. To be able to conclude that a time-restricted eating pattern causes a weight loss in this population on average, we would need to ___________.
O use a much larger sample than what this study used
O collect weight-loss data on all adults, not just adults with metabolic syndrome
O find a significant weight-loss difference for participants that would be randomly assigned to time-restricted eating or regular eating
O collect weight-loss data on the entire population of adults with metabolic syndrome
O make sure that the study found a very small P-value and check that the conditions for inference were all met
Answer:
Option A
Step-by-step explanation:
To conclude that a time-restricted eating pattern causes a weight loss in this population on average, we would need to use a much larger sample than the 19 actually used in the study to get an unbiased conclusion and to also ensure that the sample itself and whatever result produced is a true representation of this particular population itself.

What is the volume, in cubic cm, of a rectangular prism with a height of 19cm, a
width of 16cm, and a length of 8cm?
Answer: 2432
19 x 16 x 8 = 2432
Answer: 2,432 cm³
Step-by-step explanation: To find the volume of a rectangular prism or a prism whose base is a rectangle, we use the formula below.
Volume = length × width × height
Since the rectangular prism has a length of 8 centimeters, a width of 16 centimeters, and a height of 19 centimeters,
we can plug this information into the formula to get
(8 cm)(16 cm)(19 cm).
This gives us 2,432 cm³.
So the volume is 2,432 cm³.
A fenced enclosure consists of a rectangle (length L and width 2R) attached to a semicircle with a radius R as pictured below. Note: there is fencing between the rectangular and semi-circular portions. The enclosure is to be built to have a total area (the entire shaded region), A, of 2000 ft2. The cost of the fence is $20/ft for curved sections and $30/ft for straight sections. Analytically (show all of your steps using algebra and calculus in the write up), find the minimum cost to build the fence and the dimensions of the enclosure. Show all equations that you derive and use. This part should be done entirely in the write-up: no coding. It is fine to do this by hand and include a high-resolution picture in the writeup rather than using Equation Editor. Hint: you will need to use two equations in order to find the cost as a function of only R or L. Construct a plot to graphically determine the values of R and L (x-axis) that minimize the total cost (y-axis) of the fence. Using the MIN function, determine the R and L that minimize cost and what that cost is Do your answers in A, B and C all agree? Why or why not?
Answer:
A. $ 6053.44
B. From the graph, R = 21.027 ft and C = $ 5700.005, L = 31.043 ft
The values in A and B do not all agree. This could be due to error in approximations. Their values are close though.
Step-by-step explanation:
A. The area A of the enclosure equals, A = 2RL + πR²/2.
The total cost C = 20 × length of curved section + 30 × length of straight section
C = 20πR + 30[2(L + 2R)]
= 20πR + 60L + 120R
Making L subject of the formula from A,
L = A/2R - πR/4
Substituting L into C, we have
C = 20πR + 60(A/2R - πR/4) + 120R
= 20πR + 30A/R - 15πR + 120R
= 5πR + 30A/R + 120R
We now differentiate C with respect to R to find the value of R for minimum cost
dC/dR = 5π - 60A/R² +120
Equating dC/dR to zero, we have
5π - 60A/R² + 120 = 0
So, R = ±√[60A/(5π + 120)]
substituting A = 2000 ft²
R = ±√[60 × 2000/(5π + 120)] = ±29.74 ft
We take the positive answer, R = 29.74 ft since R cannot be negative.
To determine if this is a minimum point, we differentiate dC/dR with respect to R.
So d²C/dR² = 120A/R³
Since d²C/dR² = 120A/R³ > 0 for positive R, it is a minimum point.
Substituting the value of R into C we have
C = 5πR + 30A/R + 120R
= 5π(29.74) + 30 × 2000/29.74 + 120(29.74)
= 467.155 + 2017.485 + 3568.8
= $ 6053.44
and L = A/2R - πR/4
= 2000/2(29.74) - π(29.74)/4
= 33.625 - 23.356
= 10.269
≅ 10.27 ft
B. From the graph, R = 21.027 ft and C = $ 5700.005, L = 31.043 ft
The values in A and B do not all agree. This could be due to error in approximations. Their values are close though.

If you were to roll a six-sided number cube 60 times, about how many times would you expect the number cube to land on a 1?
Answer:
10
Step-by-step explanation:
Probability is the likeliness of happening of an event.
Probability of any event A can be be defined by
no. of time event A happens/ total no. all possible event that can occur
___________________________________
In the problem
probability of occurrence of 1 on rolling a cube is needed.
A cube has six sides with one written on one sides and rest has 2,3,4,5,6.
No of times 1 can occur on rolling the dice once will be = 1
Since there six sides and and each has different number (1,2,3,4,5,6)
There is chance that each of the number can come.
Thus, total no possible outcome = 6
Probability of occurrence of 1 = No of times 1 occurs on rolling the dice /total no possible outcome = 1/6
_____________________________________________
If dice is rolled 1 time there is 1/6 chance that 1 will be the outcome.
If dice is rolled 1*60 time then there is 1/6*60= 10 chance that 1 will be the outcome
Thus , If you were to roll a six-sided number cube 60 times, about 10 times it is expected that the number cube to land on a 1.
