The required unit rate for the dollars per class is 16 dollars per class,

Given that,
The "constant of proportionality" between to cost and the number of classes is 16. The unit rate for dollars per class is to be determined.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Let, y be the dollars is directly proportional to the x classes,
According to the question,
y = kx
k = 16
y = 16x
Now,
y/x = 16 dollars per class

Thus, the required unit rate for the dollars per class is 16 dollars per class,

Step-by-step

We are told that 6 is two-fifths of the brownies. So we can figure it out as such:

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

Cross multiply

6 * 5 = x * 2

30 = 2x

Divide both sides of the equal sign by 2 to get x by itself

[tex]\frac{30}{2} =\frac{2x}{2}[/tex]

15 = x

15/5 = 3. Every third piece is 1/5 of the pan.

One of the interior angles of the triangle, angle y is equal to 67° and the exterior angle x is equal to 113°.

The interior angles of a triangle have a total sum of 180°.

Considering the triangle with interior angles: y, 51°, and 62° we have that;

y + 51° + 62° = 180°

y + 113° = 180°

y + 113° - 113° = 180° - 113° {subtract 113° from both sides}

y = 67°

the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.

x + 67° = 180°

x + 67° - 67° = 180° - 67° {subtract 67° from both sides}

x = 113°

Therefore, the interior angle y = 67° and the exterior angle x = 113°.

2.1m/s is the tip of his shadow moving when he is 15 m from the pole

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

x is the distance from the man to the pole, and y is the distance from the tip of the man's shadow to the pole. i assume the man and pole are standing straight up, which means the 2 triangles are similar.

(y-x)/y=2/6

(y-x)/y=1/3

Apply cross multiplication

3(y-x)=y

3y-3x=y

2y=3x

y=3/2x

differentiate both sides with respect to t or time.

dy/dt=3/2dx/dt

By given dx/dt=1.4m/s

dy/dt=3/2×1.4

dy/dt=2.1m/s

Total amount payable including sales tax and tip =  $68.12

A sales tax is a tax levied by a government on the sale of certain goods and services. Generally, laws allow the seller to collect tax funds from the consumer at the point of sale. A use tax is a tax on goods or services paid directly to a governing body by a consumer.

Given:

Bill at dinner was before tax and tip = $58.24

Sales tax = 6%

Tip = 18%

As per the question:

first, we will calculate the amount payable after adding tax.

The amount payable after adding sales tax = bill + 6% sales tax of the bill

The amount payable after adding sales tax = 58.24 + [tex]\frac{6}{100} 58.24[/tex]

Amount payable after adding sales tax = A = $57.73

Now we will calculate the total amount payable after adding the tip.

Total amount payable = A + 18% of A

Total amount payable = $57.73 + 18% of $57.73

Total amount payable =  57.73 + 10.40

a) The velocity of the particle is described by v(t) = - 3 · t² + 12 · t - 9.

b) The particle is at rest when t = 1 s. and t = 3 s.

c) The particle changes its direction when t = 1 s. and t = 3 s.

d) The particle is moving right when 0 s < t < 1 s and t > 3 s and left when 1 s < t < 3 s.

e) The acceleration of the particle is described by a(t) = a(t) = - 6 · t + 12.

f) The velocity increases at t = 1 s.

g) The particle has a total distance of 54 meters.

In the statement we find the function of a particle that describes its position (y), measured in meters, in time (t), in seconds. Herein we shall analyze the function to determine all important features.

a) The velocity of the particle (v), in meters per second, is the first derivative of the function position:

v(t) = - 3 · t² + 12 · t - 9

b) The particle is at rest when v(t) = 0. Now we proceed to determine the roots of the resulting polynomial:

- 3 · t² + 12 · t - 9 = 0

t = 3 s. or t = 1 s.

c) The particle changes its direction when v(t) = 0. Then, this change happens in t = 1 s and t = 3 s.

d) The particle is moving right when v(t) > 0, then:

(t - 1) · (t - 3) > 0

There are two possible intervals: (i) 0 s < t < 1 s, (ii) t > 3 s. The particle is moving left when 1 s < t < 3 s.

e) The acceleration is the second derivative of function position, thus:

a(t) = - 6 · t + 12

f) The velocity increases when a(t) > 0. Then, the acceleration at t = 1 s is:

a(1) = - 6 · 1 + 12

a(1) = 6

The velocity is increasing at t = 1 s.

g) The total distance (s), in meters, traveled is determined by the following expression:

s = |x(1) - x(0)| + |x(3) - x(1)| + |x(6) - x(3)|

s = |7 - 11| + |11 - 7| + |- 43 - 11|

s = |- 4| + |4| + |- 54|

Describe a linear equation using an example.

An equation with only one variable is referred to as a linear equation in one variable.

Therefore, Andy takes 1.1 hours.

Beth walked 1 1/2 mi at a constant speed of 1 1/8 mi/h .

  time = [tex]\frac{1 1/2}{ 1 1/8}[/tex]

since AD is an altitude (height) of ABC, the angle at D must be 90° (that is the definition of an altitude or height).

so,

90 = x² + 6x + 18

72 = x² + 6x

0 = x² + 6x - 72

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-6 ± sqrt(6² - 4×1×-72))/(2×1) =

x2 = -3 - 9 = -12

so, the 2 solutions are
