If the total number of juice boxes is 20 and to distribute the juice boxes among 6 friends, The number of juice boxes can you give to each friend will be 3.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

You are given 20 juice cartons, which you distribute to each of your friends. You want to give the same number of juice boxes to each of your six friends.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

The number of juice boxes can you give to each friend is,

=20/6

=3.333 ≈ 3

Thus, if the total number of juice boxes is 20 and to distribute the juice boxes among 6 friends, The number of juice boxes can you give to each friend will be 3.

Answer:

7+(((3^2)*((-5)+1))/2

=-11

Step-by-step explanation:

x - 3y = -11
-x + 2y = 7

We minus these equations : x - 3y - (-x + 2y) = -18

= x - 3y + x - 2y = -18
2x - 5y = -18

Now, we add these equations :

x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4

Replace it in 2x - 5y = -18

2x - 20 = -18

2x = -18 + 20 = 2
x = 1

Recheck : 1 - 3 x 4 = -11

-1 + 8 = 7.

**rate of change for f(x)**

f(x)=-0.3x^2

-0.3(1)^2=-0.3^2=-0.09

-0.03(5)2=-0.15^2=-0.0225

rate of change = (-0.0225-(-0.09))/(5-1)=0.0675/4=0.016875

f(x) rate of change is 0.016875 or about 0.02

**rate of change for g(x)**

g(x)=-0.6x^2

-0.06(1)^2=-0.06^2=-0.0036

-0.06(5)^2=-0.3^2=-0.09

rate of change = (-0.09-(-0.0036))/(5-1)=-0.0864/4=-0.0216

g(x) rate of change is -0.0216 or about -0.02

**how much greater?**

0.02(-1)=-0.02

Answer:

I'm guessing the question asks us what is the current balance of the dress after 7 weeks.

So it if drops by 10% every week, we need to find how much it went down one week;

consider 10% as 10/100 in fraction form;

10/100 x 150 = $15, it goes down by $15 each week, but we need to find how much 7 weeks would be:

7 x $15 = $105, it went down $105 so we need to subtract that from the total:

150 - 105 = $45, it would now be currently up for sale for $45.

Matthew got eight oranges.

Answer: the answer is 33/100 or .33

Answer:

33/100

Step-by-step explanation:

Because since 4/10 + ?= 73/100 that means the denominator get's change so we know that the demonter for the ? number had to have 100 as a denominator.

And since that number has a 100 for their demonter that means we times our demonter(10 until it get's to 100 so how many times do we times 10 to it get's to 100? the answer is 10.

So since we times our denominator we also have to times our numerator by 10 as well what is 4 times 10? Our answer is 40.

So now our fraction 4/10 is now 40/100. what= 73 when you add it to 40?

Our answer for that is 33 how I know is 40+ 33= well lets add the tens what is 40 + 30=70 now add ones 3 so 73 and our denominator is already the same and our fraction now is 73/100. and there's our answer.

4/10(40/100 now because of the calculations) + 33/100=73/100 so we figured out our mysterious fraction| Mysterious fraction=73/100.

Answer:

Daniel will need 9 loaves of bread (108 slices)

Step-by-step explanation:

Daniel eats 18 slices of bread a week.

2 slices per week day (2 x 5 = 10)

4 slices per weekend day (4 x 2 = 8)

10 + 8 = 18

he will be there 6 weeks

18 x 6 = 108.

There are 12 slices of bread per loaf.

108 divided by 12 = 9.

Therefore, he will need 9 loaves of bread.

The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

The square can be defined as a two-dimensional figure that has 4 equal sides.

Given are the equations of the areas of the polynomial.

Option C: [tex]16 x^2 + 24x +9[/tex]

We can write the above equation as,

[tex](4x)^2 + 2 \times 4x \times 3 + (3)^2[/tex]

[tex](a+b)^2 = a^2 + 2ab+b^2[/tex]

Here a = 4x  and b = 3, so

[tex]16x^2 + 24x+9 = (4x+3)^2[/tex]

The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.

Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

Answer:

Step-by-step explanation:

Hi there!

We want to see if 9, 40, and 41 can be the sides of a triangle that can exist

We can use triangle inequalities to figure that out

For triangle inequalities, if the lengths of the sides are a, b, and c, then a+b>c, b+c>a, and c+a>b, then the lengths can make a triangle
Let's say that a=9, b=40, and c=41

Now substitute these values into the inequalities:

a+b>c

9+40>41

49>41

This is a true statement.

b+c>a

40+41>9

81>9

This is also a true statement.

41+9>40

50>40

This is a true statement as well.

Since all three of the inequalities ended up being true (all three NEED to be true in order for the given lengths to make a triangle), then we can confirm that 9, 40, and 41 can make a triangle

Hope this helps!
