The truck travelled 0.42 miles per minute

The given parameters are:

Distance = 75 miles

Time = 3 hours

Convert time to minutes

Time = 3 * 60 minutes

Time = 180 minutes

The speed is calculated as:

Speed = Distance/Time

This gives

Speed = 75 miles/180 minutes

Evaluate

Speed = 0.42 miles per minutes

The length of awning which covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall, is 44.7 inches.

The law of sine is nothing but the relationship between the sides of the triangle to the angle of the triangle (oblique triangle).

It can be given as,

\(\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}\)

Here (A,B,C) are the angle of the triangle and (a,b,c) are the sides of that triangle.

An awning that covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall.

The figure of the problem is attached below. The length of AB which is L has to be find out.

The purpose of the awning is to prevent sunlight from entering the house when the angle of elevation of the sun is more than X = 60°. Thus, the angle ABC is 30 degrees.

\(AB=90-60\\AB=30^o\)

The sum of all the interior angle is 180 degree. Thus, the angle ACB is,

\(\angle ACB=180-50-30\\\angle ACB=100^o\\\)

Let suppose, the length of AB is a. Thus, by the sine law,

\(\dfrac{\sin 30}{a}=\dfrac{\sin 100}{88}\\a=\dfrac{88\times\sin 300}{\sin 100}\\a=447\rm\; in\)

Thus, the length of awning which covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall, is 44.7 inches.

The difference quotient of the function f(x) = 4x² - 5x is 8x + 4h - 5.

The formula for difference quotient is expressed as:

\(\frac{f(x+h)-f(x)}{h}\)

Given the function in the question:

f(x) = 4x² - 5x

To solve for the difference quotient, we evaluate the function at x = x+h:

First;

f(x + h) = 4(x + h)² - 5(x + h)

Simplifying, we gt:

f(x + h) = 4x² + 8hx + 4h² - 5x - 5h

f(x + h) = 4h² + 8hx + 4x² - 5h - 5x

Next, plug in the components into the difference quotient formula:

\(\frac{f(x+h)-f(x)}{h}\\\\\frac{(4h^2 + 8hx + 4x^2 - 5h - 5x - (4x^2 - 5x)}{h}\\\\Simplify\\\\\frac{(4h^2 + 8hx + 4x^2 - 5h - 5x - 4x^2 + 5x)}{h}\\\\\frac{(4h^2 + 8hx - 5h)}{h}\\\\\frac{h(4h + 8x - 5)}{h}\\\\8x + 4h -5\)

The measurement that is closest to the value of x, in centimeters, is given as follows:

14.3.

In this problem, we have a right triangle, in which the legs, which are the sides between the angle of 90º, are of 11.9 cm and 7.9 cm.

Then the hypotenuse x, which is the segment connecting both legs, is obtained using the Pythagorean Theorem.

The Pythagorean Theorem states that the measure of the hypotenuse squared is equals to the sum of the squares of the measures of each side.

Then the length of x is calculated as follows:

x² = 11.9² + 7.9²

x = square root of (11.9² + 7.9²)

x = 14.28.

Closest to 14.3, rounding to the nearest tenth, meaning that the third option is correct.

Answer:

x = 25

Step-by-step explanation:

From the given picture,

In ΔMLN,

m∠NML + m∠MLN + ∠LNM = 180°

61° + 39° + m∠LNM = 180°

100° + m∠LNM = 180°

m∠LNM = 180° - 100°

m∠LNM = 80°

If JK║MN and JN is a transverse intersecting these parallel lines at N and J,

∠LNM ≅ ∠LJK [Alternate interior angles]

(3x + 5)° = 80°

3x = 80 - 5

3x = 75

The option "The landlord wants to increase the rent more than 20%" is NOT a valid "just cause" for evicting a residential tenant under the Tenant Protection Act of 2019.

In the Tenant Protection Act of 2019, there are several "just causes" for evicting a residential tenant. However, one of the following options is NOT considered a "just cause" for eviction:

- The landlord wants to increase the rent by more than 20%.

Under the Tenant Protection Act of 2019, a landlord cannot evict a residential tenant solely because they want to increase the rent by more than 20%. This is not considered a valid reason for eviction under this act.

Here is a step-by-step explanation:

1. The Tenant Protection Act of 2019 was signed by Governor Gavin Newsom on 10/08/2019.
2. This act outlines various "just causes" for evicting a residential tenant.
3. A "just cause" refers to a valid reason for eviction under the law.
4. Some of the "just causes" include a default in rent payment, the property being used for criminal or unlawful purposes, or the property being withdrawn from the rental market.
5. However, the act specifically states that a landlord cannot evict a residential tenant solely because they want to increase the rent by more than 20%.
6. This means that if a landlord wants to increase the rent by more than 20%, they cannot use that as a reason to evict a tenant under the Tenant Protection Act of 2019.

In summary, the option "The landlord wants to increase the rent more than 20%" is NOT a valid "just cause" for evicting a residential tenant under the Tenant Protection Act of 2019.

Answer:

y=52 (or 90) - please read the explanation to understand what I mean

x=52

Edit: So basically what happened is that I thought that y was only that one angle, so I did that part of the problem wrong.

This is how it should be done:

We can look at the angles 38 and y. Together, the two angles form a straight angle. So, to find y, do 180-38.

180-38=142

Sorry for the mistake earlier! The diagram wasn't too clear and I thought the y was the one that wasn't the right angle...

Step-by-step explanation:

The measure of all the angles will always add to 360°. We can draw an imaginary circle around all the angles to visualize this. This also means that half a circle will add to 180°.

180 = 38+90+y

= 128+y

y=52

(By the way, if the y was the one with the right angle, it would be 90. You might want to try both, as the picture isn't too clear as to which one it is.)

Now to solve for x, we again see that half of our imaginary circle would add up to 180°. However, we need to choose a half that has more angles. Let's go with the half that has the 38° and the right angle, which equals 90°.

180=38+90+x

=128+x

x=52

I have attached a couple of screenshots so you can hopefully see what I mean by an imaginary circle.

Sorry for the bad handwriting - I'm on a computer right now so I can't really write well....

I hope this is correct and good luck on your homework!

The measure of angle x = 52 degree and angle y = 142 degree.

In the given figure;

The three intersecting lines are given

In which one inclination angle is 38 degree

And second is right angle.

To find value of y

from figure;

y + 38 = 180

⇒ y = 180-38 = 142 degree

To find value of y

⇒  x + 38 + 90 = 108

⇒ x = 52 degree

Hence, x = 52 degree and y = 142 degree.

Yes, Abcd is a parallelogram because both pairs of opposite sides are parallel. This means that the line segments AB and DC are parallel, as well as the line segments AD and BC. Because opposite sides of a parallelogram are congruent, we can also say that AB is congruent to DC, and AD is congruent to BC.

Furthermore, because AB and DC are parallel, we know that angles A and D are congruent (as corresponding angles), as well as angles B and C. This is due to the fact that when a transversal intersects two parallel lines, the alternate interior angles are congruent.

Overall, these characteristics of a parallelogram (parallel sides and congruent opposite angles) make it a unique and important quadrilateral in geometry.
In a parallelogram, both pairs of opposite sides are parallel. Therefore, if ABCD has opposite sides AB and CD parallel, as well as opposite sides AD and BC parallel, it can be classified as a parallelogram.

There are 60,480 ways to seat 6 people in a row of 9 chairs using the multiplication principle of counting.

There are 9 choices for the first person, 8 choices for the second person (since one chair is already taken), 7 choices for the third person, and so on. Therefore, the total number of ways 6 people can be seated in a row of 9 chairs is:

\(9 * 8 * 7 * 6 * 5 * 4 = 60,480\)

So there are 60,480 ways to seat 6 people in a row of 9 chairs.

To count the number of ways 6 people can be seated in a row of 9 chairs, we can use the multiplication principle of counting.

First, we consider the number of choices for the first person. Since there are 9 chairs and the order in which the people are seated matters, there are 9 choices for the first person. Once the first person is seated, there are 8 chairs remaining for the second person to choose from, since one chair is already taken. Therefore, there are 8 choices for the second person. Continuing in this way, there are 7 choices for the third person, 6 choices for the fourth person, 5 choices for the fifth person, and 4 choices for the sixth person.

To find the total number of ways to seat 6 people in a row of 9 chairs, we multiply the number of choices at each step together. Hence, the total number of ways is:

\(9 * 8 * 7 * 6 * 5 * 4 = 60,480\)
