24 months.

Step-by-step explanation:

168 sellouts.

7 times per month.

So to find the amount of months, all we have to do is divide the sellouts by the times per month.

168/7=24.

24 months.

Answer:

y = 65°

Step-by-step explanation:

z = 70° (corresponding angels are equal)

y + z = 135° (exterior angle theorem of a triangle)

y + 70 = 135 (substitution)

Subtract 70 from each side

y + 70 - 70 = 135 - 70

y = 65

Answer:

y= -2x-2

Step-by-step explanation:

All parallel lines have the same slope. So, the line we create must have a slope of -2. If we multiply the x value by -2, we can find b through an equation.

-4 would be x in this case because it's a point we pass.

So, our equation would be

y= -2(-4)+b

y=8+b

Now, we know that y is 8+b. We can find b by plugging in y=6, because those are the coordinates of P.

6=8+b

b=-2

Now we know that b is -2. We put this into the equation for the parallel line and get:

y=-2x-2

Answer:

8 units.

Step-by-step explanation:

Given points:

Graph the given points (x, y) on the coordinate plane.  (See attachment).

Distance between two points

\(\boxed{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\)

where (x₁, y₁) and (x₂, y₂) are the endpoints.

Substitute the given points into the distance formula and solve for d:

\(\implies d=\sqrt{(-6-2)^2+(3-3)^2}\)

\(\implies d= \sqrt{(-8)^2+(0)^2}\)

\(\implies d=\sqrt{64+0}\)

\(\implies d=\sqrt{64}\)

\(\implies d=8\; \sf units\)

Therefore, the distance between the two given points is 8 units.

As the two points have the same y-value, the two points are on a horizontal line. Therefore, the distance between them can be calculated by simply determining the difference in their x-values:

\(\implies 2-(-6)=8\; \sf units\)

Rebecca should expect 5 of her classmates to walk to school.

We can use the formula for expected value:

Expected value = probability of an event happening x number of possible outcomes

In this case, the probability of a classmate walking to school is 4/30, since 4 out of the 30 students walk to school.

So, the expected number of classmates that should walk to school is:

Expected value = (4/30) x 6 = 0.8 x 6 = 4.8

Hence, Rebecca should expect 5 of her classmates to walk to school.

To find the component form of v given its magnitude and the angle it makes with the positive x-axis, we can use the following formula , the component form of v is (3.9944, 0.2092) when its magnitude is 4 and it makes an angle of 3.5° with the positive x-axis.

We have ,

v = ║v║ (cos θ, sin θ)

where ║v║ is the magnitude of v, θ is the angle it makes with the positive x-axis, and (cos θ, sin θ) represents the direction of v in terms of the unit vector components along the x-axis and y-axis.

Substituting the given values, we get:

v = 4(cos 3.5°, sin 3.5°)

Using a calculator, we can find the cosine and sine values:

v = 4(0.9986, 0.0523)

Multiplying each component by 4, we get:

v = (3.9944, 0.2092)

Therefore, the component form of v is (3.9944, 0.2092) when its magnitude is 4 and it makes an angle of 3.5° with the positive x-axis.

Applying one of the properties of a parallelogram, the value of x is 10°, then 6x=60° and 12x=120°.

There are different quadrilaterals, for example square, rectangle, rhombus, trapezoid, and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, a parallelogram presents some properties that are presented below.

The figure of the exercise shows two adjacent angles. From the property: the adjacent angles are supplementary, you have:

6x+12x=180

18x=180

x=10°

Therefore, 6x= 6*10=60° and 12x=12*10=120°.

Based on the variable declarations and initializations you provided:
int a = 2; int b = 6; int c = 3;
An expression that evaluates to false would be one where the conditions are not met. For example:
(a + b == c)
This expression checks if the sum of a and b is equal to c. In this case, (2 + 6) is not equal to 3, so the expression evaluates to false.

One possible solution is:
The given variable declarations and initializations are:
int a = 2;
int b = 6;
int c = 3;

To evaluate which of the following expressions is false, we need to look at each expression and see if it produces a Boolean value of false.
a < b || c > b

This expression is true because 2 is less than 6 and 3 is greater than 6. Therefore, the OR operator (||) returns true because at least one of the operands is true.
a + b > c && c - a < b

This expression is true because 2 + 6 is greater than 3 and 3 - 2 is less than 6. Therefore, the AND operator (&&) returns true because both operands are true.
b % c == a || c * b < a

This expression is false because 6 % 3 is equal to 0, which is not equal to 2. Therefore, the equality operator (==) returns false. Moreover, 3 times 6 is 18, which is not less than 2. Therefore, the second operand is also false. Therefore, the OR operator (||) returns false because both operands are false.

Therefore, the expression "b % c == a || c * b < a" evaluates to false.

x - 7 = 0

Add 7 to both sides

x = 7

Substitute x = 7 in f(x) = 0

f(7) = 0

To calculate the concentrations of all species present in a 0.72 M NH3 solution (Kb=1.8×10−5), we can use the principles of the equilibrium expression for the dissociation of NH3 in water.

NH3 (ammonia) is a weak base that reacts with water to form NH4+ (ammonium) and OH- (hydroxide) ions. The equilibrium expression for this reaction can be written as:

NH3 + H2O ⇌ NH4+ + OH-

Since the initial concentration of NH3 is 0.72 M, we can assume that x mol/L of NH3 will dissociate to form x mol/L of NH4+ and OH-. Therefore, the concentrations of NH4+ and OH- will also be x mol/L.

To calculate the value of x, we can use the Kb expression, which relates the equilibrium constant to the concentrations of the species. In this case, Kb = [NH4+][OH-]/[NH3]. Substituting the known values, we have:

1.8×10−5 = x * x / (0.72 - x)

Solving this equation will give us the value of x, which represents the concentration of NH4+ and OH-. Finally, we can express the concentrations of NH3, NH4+, and OH- using two significant figures, separated by commas, based on the calculated value of x.

The correct option is OA. y+4= -3(x-3). L 4.6.3 Test (CST): Linear Equations Solution: We are given that a line passes through (3,-4) and has a slope of -3.

We will use point slope form of line to obtain the equation of liney - y1 = m(x - x1).

Plugging in the values, we get,y - (-4) = -3(x - 3).

Simplifying the above expression, we get y + 4 = -3x + 9y = -3x + 9 - 4y = -3x + 5y = -3x + 5.

This equation is in slope intercept form of line where slope is -3 and y-intercept is 5.The above equation is not matching with any of the options given.

Let's try to put the equation in standard form of line,ax + by = c=> 3x + y = 5

Multiplying all the terms by -1,-3x - y = -5

the signal will have a triangular shape, with the peak at t=1 and the lowest point at t=-1. As time progresses from -1 to 1, the periodic signal will linearly increase from -1 to 1. At t=1, the signal will reset back to -1 and repeat the pattern.

The given signal is defined piecewise for the interval -1<x<1. For -1<x<0, the signal is -t, which means it starts from -1 and linearly decreases to 0 as t increases. For 0<x<1, the signal is t, which means it starts from 0 and linearly increases to 1 as t increases.

Since the period Tp is defined as 2s, the signal will repeat its pattern every 2 seconds. This means that for any integer n, x(t) will be equal to x(t + nTp). In other words, the signal will repeat its pattern every 2 seconds, regardless of the value of n.
