Write a story for this equation: $10 - $4.05 = c.​

Answer: Point F is at location (-4, -5)

The x and y axis meet at the origin (0,0)

Start at the origin and move 4 units to the left. This means the x coordinate is x = -4

Then move 5 units down so the y coordinate is y = -5

Put together (x,y) = (-4, -5) describes where point F is located.

Answer:

(-4-5)

Step-by-step explanation:

I'm confused as to why there's a random "10" but the answer is actually pretty simple. Insert (11-210) into the problems.

Basically substitute (11-210) into the numbers with the x variable.

The correct answer is 367,244.

Number System is a method of representing Numbers on the Number Line with the help of a set of Symbols and rules. These symbols range from 0-9 and are termed as digits. Number System is used to perform mathematical computations ranging from great scientific calculations to calculations.

Positive Numbers: Numbers that are represented on the right side of the zero are termed as Positive Numbers. The value of these numbers increases on moving towards the right. Positive numbers are used for Addition between numbers. Example: 1, 2, 3, 4, …

Negative Numbers: Numbers that are represented on the left side of the zero are termed as Negative Numbers. The value of these numbers decreases on moving towards the left. Negative numbers are used for Subtraction between numbers. Example: -1, -2, -3, -4, …

as per the situation given,

we have number has a thousands digit that is ten times greater than the hundreds digit.

So, the number is 367244 because 7 is 5 greater than 2.

Answer:

Hey there!

Cone formula: [tex]\pi[/tex]hr^2/3

Plugging in the values, we get the volume is 301.59

Let me know if this helps :)

Answer:

96π

301.59

Step-by-step explanation:

The volume of a cone can be calculated using the following formula:

[tex]V=\frac{1}{3}bh[/tex]

b is the base and h is the height. The base formula for a circle (area):

[tex]b=\pi r^2[/tex]

Insert this value into the formula:

[tex]V=\frac{1}{3}\pi r^2h[/tex]

Simplify the formula:

[tex]V=\frac{\pi r^2h }{3}[/tex]

Now insert the known values:

[tex]V=\frac{\pi(6)^2(8) }{3}[/tex]

Simplify:

[tex]V=\frac{\pi*36*8 }{3}\\\\V=\frac{288\pi }{3}\\\\V=96\pi[/tex]

The volume is 96π units³ or 301.59 units³.

24pix^3+24pix^2+6pix

Answer:

C

Explanation:

Volume for a cylinder is V= (pi)(r^2)(h)

r being radius, h being height.

The radius is 2x+1, so square that

(2x+1)^2 = 4x^2 + 4x + 1

Then multiply by 6x, the height

(4x^2 + 4x + 1)(6x) = 24x^3 + 24x^2 + 6x

Then multiply each term pi, which would be answer C.

Answer:

Step-by-step explanation:

If the first floor of the Willis Tower is 21 feet high. and each additional floor is 12 feet high, then the floor heights as we move from one floor to another we keep increasing by 12feets and forms an arithmetic progression as shown;

21, (21+12), (21+12+12), ...

21, 33, 45...

a) To write an equation for the nth floor of the tower, we will have to find the nth term of the sequence using the formula for finding the nth term of an arithmetic sequence.

The nth term of an arithmetic sequence is expressed as [tex]T_n = a + (n-1)d[/tex]

a is the first term = 21

d is the common difference = 33-21 = 45-33 = 12

n is the number of terms

Substituting the given parameters into the formula;

[tex]T_n = 21+(n-1)*12\\T_n = 21+12n-12\\T_n = 21-12+12n\\T_n = 9+12n[/tex]

Hence the equation for the nth floor of the tower is expressed as [tex]T_n = 9+12n[/tex]

b) To get the height of the 65th floor, we will substitute n = 65 into the formula arrived at in (a)

[tex]T_n = 9+12n\\T_{65} = 9 + 12(65)\\T_{65} = 9+780\\T_{65} = 789 ft[/tex]

Hence the height of the 65th floor is 789feets.

Step-by-step explanation:

It is given that the result displayed on the calculator screen is [tex]1.8E 10^{-4}[/tex]. We need to say out of all options, which options represent the equivalent number.

[tex]1.8\times 10^{-4}=\dfrac{1.8}{10^4}\\\\=\dfrac{1.8}{10000}[/tex] .....(1)

Option (2) is correct i.e. [tex]1.8E10^{-4}=1.8\times 10^{-4}[/tex]

From eq2uation (1)

[tex]\dfrac{1.8}{10000}=\dfrac{18}{100000}\\\\=0.00018[/tex]

Option (4) is correct.

Answer:

Area of diamond=8192

Area of trapezoid =72 square unit

Step-by-step explanation:

Area of diamond:

find the distance between the points:

(0,64), (64,0), (0,-64),(-64,0)

d=√(x2-x1)²+(y2-y1)²

d=√64²+64²

d=64√2=90.51( rounded to the nearest hundredth)

since it is shape of square then all sides are equal

A=length*width

A=64√2*64√2

4- Area of trapezoid= ((base a +base b)/2) h

base a=3, base b=6 height=8 ( from graph count the tiles)

Area of trapezoid = ((3*6)/2 )* 8

Area=18/2*8

Area=9*8=72 square unit

The area of a diamond is 8192 square units and the area of a trapezoid is 72 square units.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

The area of the diamond will be calculated as below:-

find the distance between the points:

(0,64), (64,0), (0,-64),(-64,0)

d=√(x2-x1)²+(y2-y1)²

d=√64²+64²

d=64√2=90.51( rounded to the nearest hundredth)

Since it is the shape of a square then all sides are equal

A=length x width

A=64√2 x 64√2

A=8192 square unit

The area of the trapezoid will be calculated as below:-

Area of trapezoid= ((base a +base b)/2) h

base a=3, base b=6 height=8 ( from graph count the tiles)

Area of trapezoid = ((3*6)/2 )* 8

Area=( 18/2 ) x 8

Area=9 x 8=72 square unit

Therefore, the area of a diamond is 8192 square units and the area of a trapezoid is 72 square units.

Answer:

Step-by-step explanation:

∠ADE =  74   {Vertically opposite angles are equal}

∠AED + 127 = 180  {Straight line }

∠AED = 180 - 127

∠AED = 53

In ΔADE,

∠DAE + ∠AED + ∠ADE = 180 {angle sum property of triangle}

∠DAE + 53 + 74 = 180

∠DAE + 127 = 180

∠DAE = 180 -127

∠DAE = 53
