C-7
D-2

Answer:

x0 is the answer I just did that question and got it right

Answer:  Answer is in the steps

Step-by-step explanation:

If we given the angle measure in variables then we will sum them up equal 180 and solve for x to determine the angle measure.

9x + x  +x+4 = 180  

   11x + 4 =  180

            -4   -4

11x = 176

x=16  

In this  case we can find the angle measures by using the expressions.

x = 16  degrees

x+4 =  20 degrees

9x =  144 degrees

The correct answer is A. 1.5 cups

Explanation:

The total of polishing wooden furniture is equivalent to the total of olive oil plus the total of lemon juice. Additionally, in this case, the result should be given in cups. First, let's consider the values given.

50% of a cup of lemon juice + 25% of a quart with olive oil

The first quantity 50% of a cup of lemon indicates half cup of lemon was added, which is equivalent to 0.5 cups as 1 cup = 100% of a cup and 50% is the half.

Now, the second quantity is provided in quarts, which is not the same as a cup. Indeed 1 quart is equivalent to 4 cups, which represents 100%. This means 100% = 4 cups. Now, to calculate the 25% follow this procedure.

1. Write the values

4  =  100 (total  percentage)

x =    25 (percentage to be calculated

2. Solve this by using cross multiplication

x100 = 4 × 25

x100 = 100

x = 100 ÷ 100

x = 1 (cups in 25%)

This means 1 cup of olive oil was added and this plus 0.5 cup of lemon juice is equivalent to 1.5 cups of solution.

Answer:

Step-by-step explanation:

When we simplify we get [tex]$$z(6xy+21x+2y+7)+30xy+105x+10y=812.$$[/tex]

Then we continue to factor to get: [tex](z+5)(6xy+21x+2y+7)&=847.[/tex]

We then see that we can factor [tex](6xy+21x+2y+7)[/tex] into [tex](z+5)(3x+1)(2y+7)&=847.[/tex]

we then do the prime factorization of 847, which i think is,  [tex]7*11*11[/tex]. we have to find the numbers that multiply to 847 and then plug them into z+5, 3x=1,2y+7.

It has to be a positive, non-negative integer, right?

We also see that 3x+1=11 so we see that x=10/3 (which wont work).

So 3x+1=7, so x=2.

So 11 has to be in another term. It has to be in 2y+7=11 so y=2

for the last term we get z+5=11 so z=6

2+2+6=10

The value of x+y+z is 8.83.

Given equation,

[tex]6xyz+30xy+21xz+2yz+105x+10y+7z=812[/tex].

We have to calculate the value of [tex]x+y+z\\[/tex].

Here,

[tex]6xyz+30xy+21xz+2yz+105x+10y+7z=812[/tex]

Adding 35 both sides, we get

[tex]6xyz+21xz+2yz+7z+30xy+105x+10y+35=812+35\\[/tex]

Taking z common we get,

[tex]z(6xy+21x+2y+7)+30xy+105x+10y+35=847[/tex]

On further simplifying, we get

[tex](z+5)(6xy+21x+2y+7+6xy+21x+2y+7)=847[/tex]

[tex](z+5)(12xy+42x+4y+14)=847[/tex]

[tex](z+5)[6x(2y+7)+2(2y+7)]=847[/tex]

[tex](z+5)(2y+7)(6x+2)=847[/tex]

Now the prime factorization of 847 is [tex]11\times11\times7.[/tex]

So,

[tex](z+5)(2y+7)(6x+2)=11\times11\times7[/tex]

Here if [tex]z+5=11\\[/tex]

[tex]z=6[/tex]

And if [tex]2y+7=11\\[/tex]

[tex]2y=4\\y=2[/tex]

Again,

[tex]6x+2=7\\x=\frac{5}{6}[/tex]

Now,

[tex]x+y+z=\frac{5}{6} +2+6[/tex]

[tex]x+y+z=0.83+8\\x+y+z=8.83[/tex]

Hence the value of x+y+z is 8.83.

Answer:

The correct option is c) $17.50/case.

Step-by-step explanation:

Note: The data in the question are merged. The data are therefore sorted and the whole question is represented before answering the question. Please, see the attached pdf file for the sorted data and the represented question.

The explanation of the answer is now given as follows:

Marginal cost refers to the cost incurred in order to produce one more unit of a product.

Therefore, marginal cost is the change in the total cost that is caused by a one-unit increase in the quantity of a commodity that is produced.

From the table in the question, the marginal cost at q = 108 can be calculated as follows:

Change in total quantity at 180 cases = 108 - Number of cases immediately before 108 = 180 - 104 = 4

Change in total cost at 180 cases = Total cost at 108 cases - Total cost immediately before 108 cases = 1990 - 1920 = 70

Marginal cost at 108 cases = Change in total cost at 180 cases / Change in total quantity at 180 cases = 70 / 4 = 17.50 per case

Therefore, the correct option is c) $17.50/case.

3) shaded region =  area circle - area rectangle = 132.665 cm - 60 cm^2= 72.665 cm^2

4) 1 foot = 30.48 cm,  6 feet = 182.88 cm  = radius 182.88 cm  area circle =  pi x square radius  = 3.14 x  182.88 ^2  ---------->  3.14 x 33445.0944  =105017.5964 cm^2  

if 5.49 = 70%   , 100% = x     so 5.49 x 100 divided 70 = X  so X = 7.844      then 5.49 is the 70 % of 7.844

Answer:

I'll say x = 8

Step-by-step explanation:

because Simplifying

2x + -3 = 3x + -11

Reorder the terms:

-3 + 2x = 3x + -11

Reorder the terms:

-3 + 2x = -11 + 3x

Solving

-3 + 2x = -11 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 2x + -3x = -11 + 3x + -3x

Combine like terms: 2x + -3x = -1x

-3 + -1x = -11 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + -1x = -11 + 0

-3 + -1x = -11

Add '3' to each side of the equation.

-3 + 3 + -1x = -11 + 3

Combine like terms: -3 + 3 = 0

0 + -1x = -11 + 3

-1x = -11 + 3

Combine like terms: -11 + 3 = -8

-1x = -8

Divide each side by '-1'.

Answer:

Kayla's reasoning is not correct.

Step-by-step explanation:

The locker problem is as follows:

Imagine you are at a school that has student lockers. There are 200 lockers, all shut and unlocked, and 200 students. Suppose the first student goes along the row and opens every locker. The second student then goes along and shuts every other locker beginning with number 2. The third student changes the state of every third locker beginning with number 3. (If the locker is open the student shuts it, and if the locker is closed the student opens it). The fourth student changes the state of every fourth locker beginning with number 4. Imagine that this continues until the 200 students have followed the pattern with the 200 lockers. At the end, which lockers will be open and which will be closed? Why?

Solution:

So from the information we know that the first student goes along the row and opens every locker.

Then the second student shuts every other locker, i.e. locker numbers 2, 4, 6, 8, 10, ..., 196, 198 and 200.

Then the third students changes the state of every third locker, i.e. he/she closes an open locker and opens a closed locker.

So the open lockers are: 1, 5, 6, 12,...

Then the fourth students changes the state of every fourth locker.

So the open lockers are: 1, 4, 5, 6, 8,....

So, on we will observe that the open lockers have a perfect square number such as, 1, 4, 9, 16,....

Consider that the pattern is as follows:

Student 1 opens the locker, Student 2 closes it, Student 3 opens it, person 4 Student and so on.

This is because the square numbers always have an odd number of factors, which leads them to be open at the end.

Take any locker number, 40, for example. Its state (open or closed) is changed for every student whose number in line is a factor of the locker number.

Student      Locker 40 status

     1                    Open

     2                   Close

     4                   Open

     5                   Close

     8                   Open

     10                  Close

    20                  Open

    40                  Close

Like all other lockers numbered with non-square numbers, it ends up closed after all the students have gone through the line because it has an even number of factors.

Consider the locker number 16:

Student      Locker 16 status

     1                    Open

     2                   Close

     4                   Open

     8                   Close

     16                  Open

Thus, we can conclude that all the doors with square numbers on them will remain open because all square numbers have an odd number of factors and the doors with non-square numbers on them will remain close because they have even number of factors.

There will be a total of 14 lockers open.

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169 and 196

So, if there are 10 lockers open in the first 100 lockers there must be only 4 other lockers opened in the next 100.
