Answer:

55.56%

Step-by-step explanation:

5/9 =.55555

.55555x100 = 55.555

rounded to 55.56

Using the substitution method, the solution to the system of linear equations, is: (6, 3).

Using 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:

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).

For x-intercepts, y is zero y = x² - 12x + 32 then x-intercept is (8,0) and (4,0)

For x-intercepts, y is zero y = x² - 10x + 24 then x-intercept is (6,0) and (4,0)

For x-intercepts, y is zero y = x² + 10x + 16 then x-intercept is (-2,0) and (-8,0)

For x-intercepts, y is zero y = x² - 25 then x-intercept is (5,0) and (-5,0)

For x-intercepts, y is zero y = x² + 8x + 12 then x-intercept is (-2,0) and (2,0)

X- intercepts is "x coordinates of a point where a line, a curve or surface intersects at x- axis".

According to the question,

a) y = x² - 12x + 32 (Put y=0)

x² - 12x + 32 = 0

(x-8) (x-4) = 0

x - 8 =0: x - 4 = 0

x = 8 and 4

x - intercept is (8,0) and (4,0)

b) y = x² - 10x + 24 (Put y=0)

x² - 10x + 24= 0

(x-6) (x-4) = 0

x - 6 = 0: x - 4 = 0

x = 6 and 4

x - intercept is (6,0) and (4,0)

c) y = x² + 10x + 16 (Put y=0)

x² + 10x + 16 = 0

(x+2) (x+8) = 0

x + 2=0: x + 8 = 0

x = -2 and -8

x - intercept is (-2,0) and (-8,0)

d) y = x² - 25 (Put y=0)

x² - 25 = 0

x² = 25

x = ± 5

x - intercept is (+5,0) and (-5,0)

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.

Answer:

  see attached

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.

Additional comment

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.

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

Blue shirt - 5/6

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.
