Answer:

Step-by-step explanation:

Let there be n number of steps on the ladder.

First, the firefighter climbed up to the middle of a ladder. so to reach the middle of the ladder he must have climbed [tex]\frac n 2[/tex] steps.

Then, after climbed 10 more steps, the total number of stairs from the ground he climbed [tex]= \frac n 2 +10[/tex].

Then, he came back down 14 steps, so the total number of stairs from the ground he climbed [tex]= \frac n 2 +10 -14=\frac n 2 -4[/tex].

Remaining steps [tex]= n - \left(\frac n 2 -4 \right)=\frac n 2 +4[/tex]

Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,

[tex]\frac n 2 +4 = 20[/tex]

[tex]\Rightarrow \frac n 2 = 20-4=16[/tex]

[tex]\Rightarrow n = 16 \times 2 = 32.[/tex]

Hence, there are 32 steps on the ladder.

Step-by-step explanation:

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

[tex]= \frac{(x^2)^2 - (y^2)^2}{x - y}[/tex]

[tex]= \frac{(x^2 - y^2)(x^2 + y^2)}{x - y}[/tex]

[tex]= \frac{(x - y)(x + y)(x^2+y^2)}{x - y}[/tex]

[tex]= x^3 + xy^2 + yx^2 + y^3[/tex]

Answer:

-11 and -1

Step-by-step explanation:

if you multiply -1 and -11, hte negatives will cancel out and it will be positive 11

if you add -11 and -1 the answer will be -12

The two numbers whose multiplication will give 11 and the add will be -12 are -1 and -11.

A quadratic equation is an algebraic expression whose power is raised to the second degree.

Mathematically, it can be expressed as:

ax² + bx + c = 0

For more examples, we can have x² -12x + 11 = 0

The way this is solved is that we are going to look for two numbers, in which:

Therefore, the two numbers are -1 and -11

SO, our quadratic equation can be re-written as:

x² - 1x - 11x  + 11 = 0

x(x - 1) -11(x - 1) = 0

(x - 11 ) (x - 1) = 0

Answer:

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Step-by-step explanation:

The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]

First I solve the expression, and then will point the error

[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]

So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.

The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]

While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Answer:

x=15 +-[tex]\sqrt{97}[/tex]/2

Step-by-step explanation:

Answer:

1.Matter is the "stuff" that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons

2.Matter can exist in one of three main states: solid, liquid, or gas.

Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.

Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.

Step-by-step explanation:

Answer:

Matter is defined as anything that has mass and takes up space. The types of matter are solids, liquids, gases, and plasma. An example of solids are the desks in school,your bones, or your house. An example of liquids is the ocean, lemonade, or blood. Gases can be hydrogen, carbon dioxide, or oxygen. Plasma can be stars.

what you just said is racist in itself, it is also wrong. If you put 1 million white people in a room with 1 million black people statistics prove there will be more racist people of color. The reason why there are more white racist people world wide is because there are more white people than any other race alive to this day, so if you want to be smart about it you would know how to make it even. It's also 30% as well compared to 39% of racist black people.

John makes a total of $1,300.

Step-by-step explanation:

We know that before his bonus, John already has $500. Then, he gets $200 every day for 4 days.

200 x 4 = $800

So, over the course of those 4 days, Johnny makes $800. Now, let's add this to the rest of his money.

800 + 500 = $1,300

Therefore, John makes a total of $1,300.

Answer:

y=2x+-4

Step-by-step explanation:

Answer:

The equation in slope intercept form (y = mx + b) is y = 2x - 4

m = the slope

b = the y intercept

The line cross the y-axis at -4 so the y-intercept (b) is -4.

You can use the slope formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.

[tex]\frac{0--4}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2

So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

Step-by-step explanation:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

300persons

Step-by-step explanation:

First we need to find the total surface area of the room expressed as;

Total surface area = 2(LW+LH+WH)

L is the length = 30ft

W is the width = 15ft

H I the height = 10ft

Substitute

TSA = 2{(30(15)+30(10)+15(10)}

TSA = 2(450+300+150)

TSA = 2(900)

TSA = 1800ft²

Since an average person uses 6 square feet of area, the total numwr of people that can stand up the room is expressed as;

Total people = TSA/average area per person

Total person =1800/6

Total person = 300persons

Hence 300persos can stand up the room
