Additional comment
The English expression is ambiguous in that we cannot tell if the number is decreased by 10 before becoming part of the product (9(n-10)), or if the correct interpretation is the one shown above. The order of operations is used as a guide, telling us that the multiplication is done before the subtraction since there is no indication of grouping.

In aclassroom 5/6 of the students are wearing blue shirts and 2/5 are wearing white shirts there are 36 students in the class how many students are wearing a shirt other than blue or white
Blue shirt - 5/6
White shirt - 2/5
Total students - 36
So the answer is
5/6 of the students wearing blue shirts out of 36 are 30.
2/5 (i.e 4/10) of the students wearing white shirts out of 36 are 24.
Remaining 5/6 students are wear shirts other than blue or white are 30.

The center of the circle is drawn in an isosceles triangle with a height ratio of 12: 5, the side is equal to 30 cm. Find the AC
Answer:
25cm
Step-by-step explanation:
**see attached diagram**
Let BH = h (height)
OH = radius r = (5/17)h ⇒ h = (17/5)r
Area ∆ABC = 1/2 × base × height = 1/2 x AC x h
substituting h = (17/5)r: = 1/2 x AC x (17/5)r
= 17/10 × AC × r
We can split the isosceles triangle into three separate triangles indicated by the red lines on the diagram attached. Because the radius always meets a tangent (points E, D and H) at a right angle, the area of each triangle will be the length of the side multiplied by the radius of the circle:
Area ∆BOC = Area ∆BOA = 1/2 × 30 × r = 15r
Area ∆AOC = 1/2 × AC × r = 1/2 × AC × r
Therefore, area ∆ABC = ∆AOC + ∆BOC + ∆BOA
=1/2 (AC)r + 15r + 15r
=1/2 (AC)r + 30r
Now we have 2 different equations for the area of the isosceles triangle ABC. Equate both equations and solve to find AC:
Area ∆ABC = Area ∆ABC
17/10 (AC)r = 1/2 (AC)r + 30r
Divide both sides by r: 17/10 (AC) = 1/2 (AC) + 30
Collect & combine like terms: 6/5 (AC) = 30
Divide by 6/5: AC = 25 cm
solve the system of linear equations by substitution. x+4y=18 y=-x+9
Using the substitution method, the solution to the system of linear equations, is: (6, 3).
System of Linear EquationsUsing substitution method, we can make one of the variables the subject of the formula for one of the equations, then find the other variable by substituting.
Given:
x + 4y = 18 --> eqn. 1y = -x+9 --> eqn. 2.Substitute y = -x + 9 into equation 1.
x + 4(-x + 9) = 18
x - 4x + 36 = 18
-3x + 36 = 18
-3x = 18 - 36
-3x = -18
x = 6
Substitute x = 6 into equation 2 to find y
y = -6 + 9
y = 3
Therefore, using the substitution method, the solution to the system of linear equations, is: (6, 3).

Question 4 of 10
For the x-values 1, 2, 3, and so on, the y-values of a function form an
arithmetic sequence that decreases in value. What type of function is it?
O
A. Exponential growth
O B. Decreasing linear
O c. Exponential decay
C.
O D. Increasing linear
Answer:
B. Decreasing linearStep-by-step explanation:
Arithmetic sequence has a linear behavior since its common difference is the slope of the line.
If y-values decrease as x-values increase then this is a decreasing function.
Correct choice is B
Answer:
Decreasing linear
Step-by-step explanation:
As x values like 1,2,3.. are decreasing with respect to y hence it's decreasing function
Also
Arithmetic progression is linear hence it's decreasing linear

Answer:

Step-by-step explanation:
The grid show the non-possibilities in red, with each number corresponding to the statement that eliminates that choice. The green square (with black text) shows the one combination that is specified already (by statement 4). The lighter green numbers show possible alternatives: first period may be Schiller or English, and room 113 will be the other one. Similarly, Art may be 3rd period or Thomlinson.
__
These choices (light green 5, light green 6) give rise to four possibilities. Working through them, you run into inconsistencies if you choose Schiller for first period. (Art must be, but can't be, in room 112.) That leaves two possibilities.
Again, you run into inconsistencies if you choose Thomlinson as the Art teacher. (The class in 112 is 2 periods after Xavier's class, not 1.)
Hence, the only viable pair of remaining choices is Schiller in room 113 and art in 3rd period.
The final schedule is shown in the attachment.

When I'm working these on paper, I use an X to mark any impossible combinations, and a circle (O) to mark a known combination. In any given 4×4 square of the grid, the remaining cells of the row and column containing a O must be Xs. Consistency must be maintained between rows and columns. This often means filling a circle in one place may result in a circle being filled in another place. Of course, once 3 of the squares in a row or column have Xs, the remaining one must be O.

How do you determine what side of a graph should be x and what side is y when graphing a scatterplot in linear regression?? For instance, in the problem below:
(screen shot attached)
Answer:
y will be the dependent variable, and x will be the independent variable.
So y is affected by x.
Regarding the problem you attached, consider if IQ affects job performance, or if job performance affects IQ.
I would say that IQ may affect job performance (as job performance does not affect IQ), so in this case x will be IQ and y will be job performance.
When data is presented in tables, it is usual for the x values to be on the left and the y values to be on the right (though, not in every case, of course!).
A circle is an assortment of focuses which are all on the periphery of the circle. Assuming that you use polynomial math and (x-h)^2 + (y-k)^2 = r^2 and the data contained in the directions (x,y) of every city, you can track down h, k and r. Then, at that point, r is the (equivalent) distance between every city and the focal point of the circle, where the new pinnacle will be assembled.
How would you make this construction to ensure that the location of the cities lie exactly on the circle?

Once sales tax is included, an $89 canoe ends up costing $97.90. What is the sales tax percentage?
Answer:
10%
Step-by-step explanation:
First, 97.90-89=8.90
8.90/89 = x/100
8.90 x 100 = 890
890/89=10%
Check Answer:
89 x 10%=8.90
89+8.90= 97.90
Therefore, the sales tax percentage is 10%
