The completed magic square is given below.

Given that, in a magic square, the numbers in each row and in each column have the same sum. This sum is called the magic sum.

We need to complete the magic square so that each row and each column has a magic sum of 0. Each integer from −4 to 4 appears exactly once.

A square is divided into smaller squares each containing a number, such that the figures in each vertical, horizontal, and diagonal row add up to the same value.

The completed magic square is given below.

The sum in the first row=-1+4+(-3)=0

The sum in the second row=-2+0+2=0

The sum in the third row=3+(-4)+1=0

Hence, the completed magic square is given below.

Answer:

512

Step-by-step explanation:

The sequence is doing the number times 2, so 4 times 2 equals 8,

8 x 2 = 16, ect

If you do this enough, you will get 512 as the 8th term.

Answer:

512 because

32x2=64

64x2=128

128x2=256

What is the value of the 8th term of the sequence 4, 8, 16, 32, ...? this is where I get 32 from

Step-by-step explanation:

-3+5=-10

−3x+5−5=−10−5

−3x=−15

−3x÷−3=−15÷-3

x=5

(-2 4/5)(1 4/5)

=-14/5×19/5

=-14×9/5×5

=-126/25

=-5 1/25

Answer:

3. x = 5

4. -5  1/25

Step-by-step explanation:

Question 3 Solving:

your equation is -3x + 5 = -10

subtract 5 from both sides to get the term with x alone: -3x = -15

divide both sides by -3 to isolate x (remember that a minus divided by minus is plus): x = 5

To check:

plug in 5 to x and see if you get -10 on both sides

-3(5) + 5 = -10

first multiply -3 and 5:

-15 + 5 = -10

then add 5 to -15:

-10 = -10

if the number are equal then you solved the equation correctly

Question 4:

multiply the whole number by the denominator, then add the numerator to the product, and that number will be your new numerator ( make sure to leave the negative sign out of this computation)

so multiply 2 and 5 to get 10, then add 4 to get 14

your new fraction is -14/5

practice doing the same thing to the other mixed fraction

you should get a new fraction of 9/5

multiply the numerators and denominators

so multiply -14 and 9, and multiply 5 and 5

you now have -126/25

divide 126 by 25 to get your whole number of the mixed fraction

you should have -5  ?/25

to find the numerator, multiply your whole number by your denominator (25 x 5 = 125), then subtract this from your numerator of the improper fraction

126-125 = 1

now you have an answer of -5  1/25

The required amount that the cashier returned to Allie is 7.20.

Given that,

Allie went to the store and spent $10.80 for her science project. She gave the cashier $20.00. To estimate the amount of change the cashier should give Allie.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Paid amount = $20
Cost of the project = $10.80
Returned amount = 20 - 10.80
Returned amount = $7.20

Thus, the required amount that the cashier returned to Allie is 7.20.

Answer:

5x-3(x-2)=4

5x-3x+6=4

x = -1

Answer:

1. 2 ≤ n ≤ 4

2. 4 * 20

3. T < 80

4. (2 * 4) + (4 * 3)

5. 16 ≤ P ≤ 32

Note: The quantities described are as follows:

1) the allowable number of players on a team  

2) the number of points,  , Han's team earns in one round if every player earns a perfect score  

3) the number of points,  , Han's team earns in one round if no players earn a perfect score  

4) the number of players,  , in a game with six teams of different sizes: two teams have 4 players each and the rest have 3 players each

5) the possible number of players in a game with eight teams

Step-by-step explanation:

1. Let the number of players be n

Since each team can have between 2 and 4 players

n ≥ 2 or 2 ≤ n, and n ≤ 2

Therefore, the allowable number of players on a team   is given by 2 ≤ n ≤ 4

2) There are four players in Han's team and a perfect score is 20

Therefore, the number of points Han's team earns in one round if every player earns a perfect score   is given by 4 * 20

3) There are four players in Han's team

Total score if each player in Han's team earns a perfect score is 4 * 20 = 80

Let the total score of Han's team be T

Therefore, the number of points, Han's team earns in one round if no players earn a perfect score   is given by T < 80

4) If two team have 4 players, it is given by 2 * 4

If the rest four teams have 3 players each, it is given by 4 * 3

Therefore, the number of players in a game with six teams of different sizes: two teams have 4 players each and the rest have 3 players each  is given by (2 * 4) + (4 * 3)

5) Let the possible number of players in a game with be P

Maximum number of players in eight teams = 4 * 8 = 32

Minimum number of players in eight teams = 2 * 8 = 16

P ≤ 32 and P ≥ 16 or 16 ≤P

Therefore, the possible number of players in a game with eight teams  is given by 16 ≤ P ≤ 32

Answer:

Ants and by roughly 118,615,000mg greater.

Step-by-step explanation:

According to a quick online search, a regular house fly weighs on average 11.5mg while an ant weighs on average 3.5mg. Now that we have the average weight of each we can multiply this number by the quantity of each to find the approximate total weight.

Flies: 3,990,000 * 11.5mg = 45,885,000mg

Ants: 47,000,000 * 3.5mg = 164,500,000mg

Therefore, based on this calculation we can clearly see that the 47 million ants will have a greater mass and this mass would be approximately

164,500,000 - 45,885,000= 118,615,000mg greater

The ants and by roughly 118,615,000mg greater.

We have given that,$3.99$ million flies or $47,000,000$ ants have a greater mass

A regular house fly weighs on average weighs on 11.5mg while an ant weighs on average 3.5mg. Now that we have the average weight of each we can multiply this number by the quantity of each to find the approximate total weight.

Therfore we can write it as,

Flies: 3,990,000 × 11.5mg = 45,885,000mg

Therefore we get the files mass 45885000mg

For Ants,

47,000,000 * 3.5mg = 164,500,000mg

Therefore, based on this calculation we  clear that the 47 million ants will have a greater mass and this mass would be approximately

164,500,000 - 45,885,000= 118,615,000mg greater

Answer: the answer is 35. Are you in k12?

Answer:

6

Step-by-step explanation:

To find the greatest common factor of two numbers you find the largest number that can evenly go into both numbers

For example, the greatest number that can even;y go into 12 and 18 is 6

6 x 2 = 12

6 x 3 = 18

There is no number greater than six that can evenly go into both of those numbers therefore it must be the GCF

Answer:

The GCF of 12 and 18 is 6 and here's how you get it...

Step-by-step explanation:

First, you need to compare the factors of 12 and 18.

12: 1, 2, 3, 4, 6, 12

18: 1, 2, 3, 6, 9, 18

To get the factors of the number, look for want numbers can be divided by that number and still get a whole number. Ex. (12 / 3 = 4) 3 is a factor of 12.

The GREATEST common factor you see they have in common is the GCF.

Answer:

337.5 mg

Step-by-step explanation:

A licensed nurse practitioner is instructed to give a patient 2700 milligrams of an antibiotic over a period of 48 hours. If the antibiotic is to be given every 6 hours

Hence: the number of doses or times the antibiotic would be administered =

48 hours/6 hours = 8 doses(times)

The amount of antibiotic that should be given in each dose is:

48 hours = 2700 mg

6 hours = x mg

Cross Multiply

48x = 2700 mg × 6 hours

x = 2700mg × 6/48

x = 2700/8
