The fraction indicating the number of students who are not wearing either blue or white shirt is:

1- 1/6- 2/3= 1/6.

36 students* (1/6)= 6 students.

**There are 6 students who are not wearing either a blue or a white shirt**.

Hope this helps~

1- 1/6- 2/3= 1/6.

36 students* (1/6)= 6 students.

Hope this helps~

First we need to define our conditions. Since the angles are complimentary, the sum of the angles must be equal to 90 degrees.

let x = first angle

y = second angle

x + y = 90

from the second condition in the problem

x + y =72 + x -y

solving for x

x= 54

therefore the shorter side is 90 - 54 = y

y = 36 degree, the shorter side

let x = first angle

y = second angle

x + y = 90

from the second condition in the problem

x + y =72 + x -y

solving for x

x= 54

therefore the shorter side is 90 - 54 = y

y = 36 degree, the shorter side

The formula of the function would be:

y = 96000(1.07)^t

The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.

Therefore, from the choices, the statements that apply to the graph are:

-The graph of the function begins at y = 96,000.

-The graph of the function shows the exponential growth.

There are 9 buses and 322 students.

Your teacher wants the buses to carry an equal number of students, however, when we do 322/9 to find out how many students are on each bus, the answer is 35.777777. Therefore, there cannot be an equal number of students on each bus, but it would be close.

We know that there will be approximately 36 students on each bus, because 35.7 rounds up to 36.

If you are looking for the exact answer, then there will be**7 buses with 36 students each, and 2 buses with 35 students each**, because (36*7) + (35 *2) = 322 students total.

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.

SO... based on that, one exterior angle would have to multiplied by whatever sum (whole number) to equal 360 degrees to find the number of sides. Here you divide 360 by one of the exterior angles, if it does not equal a whole number then it would be inaccurate.

In this case only 54 degrees would not fit into one of the exterior angles.

QUESTION POSTED AT 20/01/2020 - 12:16 PM

In solving for the solution set of the inequality 15y - 9 < 36, much like any other algebraic equation, the first step should be to isolate y. This is done as follows:

15y - 9 < 36

Adding 9 to both sides of the equation:

15y - 9 + 9 < 36 + 9

15y < 45

Dividing both sides by 15 to isolate y:

15y/15 < 45/15

y < 3

Therefore the answer is the third choice y < 3.

15y - 9 < 36

Adding 9 to both sides of the equation:

15y - 9 + 9 < 36 + 9

15y < 45

Dividing both sides by 15 to isolate y:

15y/15 < 45/15

y < 3

Therefore the answer is the third choice y < 3.

To condition in which we can justify if the forces are pulling at right angles to each other is that the sum of the squares of the two lesser number should be equal to the square of the third number.

For the first set: 12 lb, 13lb, 19lb.

12^2 + 13^2 ≠ 19^2

For the second set: 15 lb, 36 lb, 39 lb

15^2 + 36^2 = 39^2

The first pair of forces do not pull at a right angle while the second do.

Thus, the answer is letter B.

**Answer:**

Option B is the correct answer.

**Step-by-step explanation:**

For eliminating y term we need to make coefficients of y in both equations same.

Equation P: y + z = 6

Equation Q: 8y + 7z = 1

Coefficients of y in equation P = 1

Coefficients of y in equation Q = 7

So we need to multiply equation P with 7.

That is (y + z = 6) x 7

Option B is the correct answer.
