Answer 1

Answer: Kitchen cabinets can be an example of a 3D composite figure.

Imagine the sets of regular kitchen cabinets going around the walls, refrigerators and sinks in your kitchen. They are generally all connected together in one piece.

However, there are also all individual pieces. To find the total volume of the cabinets, you should break them all down into the individual single prisms.

You could also look at it as an area problem on the wall. How much total space are the cabinets taking up.

If mAD=85 degrees and mBC=31 degrees find the value

Answers

Answer: x = 11

To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.

Now, write the equation: 122 = 13x - 21

Solve this, to find the x = 11.

By the properties of angles on a circle, the degree measure of x in the circle is 11 degrees

Calculating the degree measure of x

From the question, we have the following parameters that can be used in our computation:

The circle

The angle in a circle is 360 degrees.

So, we have

Unused arcs = 360 - 85 - 31

Unused arcs = 244

This means that

2(13x - 21) = 244

So, we have

13x - 21 = 122

This gives

13x = 143

Evaluate

x = 11

Hence, the degree measure of x is 11 degrees

Angle A is a right angle in △ABC.

Which side is opposite to angle A?

side BC

side AB

side AC

Answers

side BC is opposite to angle A

Option 1 is correct. The side opposite to angle A is side BC, which is the hypotenuse.

In a triangle, the side opposite the right angle is known as the hypotenuse. Since angle A is given as a right angle in △ABC, the side opposite this right angle will be the hypotenuse.

In △ABC:

Side AB is adjacent to angle A, forming one leg of the right triangle.

Side AC is also adjacent to angle A, forming the other leg of the right triangle.

Side BC is opposite angle A and is the longest side of the triangle, making it the hypotenuse.

Therefore, side BC is opposite to angle A in △ABC.

Complete question:

Angle A is a right angle in △ABC.

Which side is opposite to angle A?

1. side BC

2. side AB

Ashur solves the following system of linear equations.

Which statement about the solution to this system can he say is true?
The values of a and b are both equal to –4.
The values of a and b are both equal to 4.
The value of a is equal to 4, and b is equal to –4.
The value of a is equal to –4, and b is equal to 4.

Answers

a. first choice

The values of a and b are both equal to –4.

The given equations that make up the systems are:

-3a+7b=-16...................(Equation 1)

-9a+5b=16...................(Equation 2)

To find the values of a and b we will have to solve the two equations. To solve the equations let us employ the method of elimination.

Let us multiply (Equation 1) by -3. This will give us:

[tex] -3\times (-3a+7b=-16)=9a-21b=48 [/tex]...........(Equation 3)

Let us now add (Equation 2) to (Equation 3) to eliminate a. This will give us:

-16b=64

[tex] \therefore b=-4 [/tex]

Plugging this value of b in any of the equations we will get the value of a. Let us plug it in (Equation 1). This gives:

[tex] -3(-4)+7b=-16 [/tex]

[tex] 12+7b=-16 [/tex]

[tex] \therefore b=\frac{-28}{7}=-4 [/tex]

Thus, out of the given options, the first option is the correct one. The values of a and b are both equal to –4.

which is the directrix of parabola with equation x^2=4y

Answers

Answer:

[tex]y=-1[/tex]

Step-by-step explanation:

We have been given an equation of parabola [tex]x^2=4y[/tex]. We are asked to find the directrix of our given parabola.

First of all, we will divide both sides of our given equation by 4.

[tex]\frac{x^2}{4}=\frac{4y}{4}[/tex]

[tex]\frac{x^2}{4}=y[/tex]

[tex]y=\frac{x^2}{4}[/tex]

Now, we will compare our equation with vertex form of parabola:

[tex]y=a(x-h)^2+k[/tex], where, (h,k) represents vertex of parabola.

We can see that the value of a is [tex]\frac{1}{4}[/tex], [tex]h=0[/tex] and [tex]k=0[/tex].

Now, we will find distance of focus from vertex of parabola using formula [tex]p=\frac{1}{4a}[/tex].

Substituting the value of a in above formula, we will get:

[tex]p=\frac{1}{4*\frac{1}{4}}[/tex]

[tex]p=\frac{1}{1}=1[/tex]

We know that directrix of parabola is [tex]y=k-p[/tex].

Substituting the value of k and p in above formula, we will get:

[tex]y=0-1[/tex]

[tex]y=-1[/tex]

Therefore, the directrix of our given parabola is [tex]y=-1[/tex].

Zhi bought 18 tickets for games at a fair. Each game requires 3 tickets. Zhi wrote the expression 18 – 3g to find the number of tickets she has left after playing g games. Diego correctly wrote another expression, 3(6 – g), that will also find the number of tickets Zhi has left after playing g games. Use the drop-down menus to explain what each part of Zhi's and Diego's expressions mean.

Answers

3- The number of tickets each game requires.
18 - The number of tickets bought.
g - The number of games played.

The "3g" represents the number of games we can determine Zhi and Diego went to. Both equations have values and variables that mean the same thing, however Diego chose to use the distributive property in setting up his equation.

Yes, Zhi's expression multiplies the tickets per game by the number of games to get the number of tickets used and then subtracts this amount from the total tickets.

Factor completely. x^2−3x−40

Answers

This expression is a generic quadratic expression, so the first thing we need to look at is the last term (-40). Is it negative or positive? What are the factors of it? If the last term is negative, we know that one binomial is a subtraction while the other binomial is an addition. You may be asking, "an addition or subtraction of WHAT?" A binomial factored out of a quadratic expression would look something like this: (x + ____). The blank would equal a factor of the last term. In this case, a pair of factors that would fit is 8 and 5.
8x5 = 40 and -8 + 5 = -3.

Plug it into the binomial example I provided above and....
(x - 8)(x+5)=40

Voila! You have your factored quadratic expression, hope this helps!

To factor the quadratic expression x² -3x -40, we find that the expression factors into (x - 8)(x + 5).

The question involves factoring the quadratic expression x² -3x -40 completely. To factor this expression, we look for two numbers that multiply to -40 and add to -3. The numbers that meet these conditions are -8 and 5, since

(-8) * 5 = -40 and

(-8) + 5 = -3.

Therefore, the expression can be factored into (x - 8)(x + 5).

The first term of a sequence is -12. The recursive formula for the sequence is an = an-1 + 9. What are the next 3 terms in the sequence?

Answers

The next three terms are: -3, 6, and 15

To get each new term, we simply add 9 to the last term. So we add 9 to -12 to get -3. Then we add 9 to -3 to get 6. Finally we add 9 to 6 to get 15

In other words,
first term = -12
second term = first term+9 = -12+9 = -3
third term = second term + 9 = -3+9 = 6
fourth term = third term + 9 = 6+9 = 15

This process repeats forever though we only need three terms in this case.

So that's why the answer is the three values -3, 6 and 15

What is the solution of the equation 5x – 1 = 45? Round your answer to the nearest ten-thousandth

Answers

Final answer:

The solution to the equation 5x – 1 = 45 is x = 9.2, rounded to the nearest ten-thousandth.

Explanation:

The solution of the equation 5x – 1 = 45 is x = 9.2.

To solve this equation, we can start by isolating the variable x. Add 1 to both sides of the equation to get 5x = 46. Then, divide both sides by 5 to solve for x, giving us x = 9.2.

Therefore, the solution to the equation 5x – 1 = 45 is x = 9.2, rounded to the nearest ten-thousandth.

at 4:00 am,there were 800,000 gallons of water remaining at a reservoir.after 4 hours of irrigation,there were 100,000 gallons of water remaining.write an equation that describes the number of gallons of water as a function of the time the field has been irrigated

Answers

Let the[tex]x-axis[/tex] presents the time, and the [tex]y-axis [/tex] the gallons of water remaining, so our first point will be (4,800000). We know from the problem that after 4 hours, at 8:00 am, there were 100000 gallons, so our second point will be (8,100000).
To relate those two points we are going to use the point slope formula:
[tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} } [/tex]
where
[tex]x_{2}[/tex] is 8
[tex]x_{1}[/tex] is 4
[tex]y_{1}[/tex] is 800000
[tex]y_{2}[/tex] is 100000

So, [tex]m= \frac{100000-800000}{8-4} [/tex]
[tex]m= \frac{-700000}{4} [/tex]
[tex]m=-175000[/tex]

Now that we have our slope, we are going to use the point-slope formula to find our equation:
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y-800000=-175000(x-4)[/tex]
[tex]y-800000=-175000x+700000[/tex]
[tex]y=-175000x+1500000[/tex]

The equation that describes the number of gallons of water as a function of the time the field has been irrigated is [tex]y=-175000x+1500000[/tex]
where
[tex]y[/tex] are the remaining gallons of water in the reservoir after [tex]x[/tex] hours
[tex]x[/tex] is the time the field has been irrigated in hours
