Question:

Jordan is cutting a 2 meter by [tex]1\frac{1}{4}[/tex] meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?

Answer:

Area of each piece of paper is [tex]1 \frac{1}{4} \ m^2[/tex].

Solution:

Length of the paper = 2 m

Width of the paper =  [tex]1\frac{1}{4}[/tex] m =  [tex]\frac{5}{4}[/tex] m

Area of the rectangle = length × width

                                    [tex]$=2\times \frac{5}{4}[/tex]

                                    [tex]$= \frac{5}{2} \ m^2[/tex]

Diagonal of a rectangle divides it into two equal parts.

Area of each piece = Area of the rectangle ÷ 2

                                [tex]$=\frac{ \frac{5}{2}}{2}[/tex]

                                [tex]$=\frac{5}{4} \ m^2[/tex]

                                [tex]$=1 \frac{1}{4} \ m^2[/tex]

Area of each piece of paper is [tex]1 \frac{1}{4} \ m^2[/tex].

I had this on my quiz hold on.. is is 48.

Step-by-step explanation:

Check the picture below.

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

well, by the definition of a derivative, the slope at the point is f'(a), and any tangent line going through it will also have the same exact slope, keeping in mind that a straight line has a constant slope.

Answer:

2.34

Step-by-step explanation:

Nope, it is 2.34 because you round it off and the 2 stays the same the three does to but the other 3 turns into a 4 because the number next to it which is a 7 is 5 and higher so that makes it 2.34 this would make sense from a mathematician even if my profile doesn't say it.

Option  A and D will not get to the required point

Step-by-step explanation:

Step 1 :

a)

Start at origin, go 112 units up and then go 4 unit to the right.

Starting at the origin, 112 units up gives y = 112

then 4 spaces to the right gives x = 4

So the point obtained is (4,112)

Hence option A will not get to the required point

Step 2 :

b)

Starting at the origin, go 4 spaces up and then 112 spaces to the right.

Starting at the origin , 4 spaces up gives y = 4

112 spaces to the right gives x = 112

So we get the point as (112,4)

Option B goes to the required point

Step 3:

c)

Starting at the origin, go 112 spaces to the right and then 4 spaces up.

Starting at the origin, 112 spaces to the right gives x = 112

4 spaces up gives y = 4

We get to the point (112,4)

Hence option C gets to the required point

Step 4:

d)

Doing the procedure in option D gives y = 4, and x as between 1 and 2

Hence this will not get to the required point

Step 5 :

Option  A and D will not get to the required point

Answer:

Step-by-step explanation:

Answer:

x= -0.4385 or -4.5615

Step-by-step explanation:

x²+5x+2=0

Using almighty formula;

a=1, b=5, c=2

x = [ -b± √( b^2 - 4ac)]/2a

x= -5±√(25-8)/2

x=(-5±4.123)/2

Therefore x=(-5+4.123)/2 or (-5-4.123)/2

x= -0.4385 or -4.5615

The solutions are [tex]\(x = \frac{{-5 + \sqrt{17}}}{2}\) and \(x = \frac{{-5 - \sqrt{17}}}{2}\).[/tex]

To find the solution of the equation [tex]\(x^2 + 5x = -2\), we need to solve for \(x\).[/tex]

Let's rearrange the equation to bring all terms to one side:

[tex]\[x^2 + 5x + 2 = 0\][/tex]

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula:

[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]

In our equation, [tex]\(a = 1\), \(b = 5\), and \(c = 2\).[/tex]

[tex]\[x = \frac{{-5 \pm \sqrt{{5^2 - 4(1)(2)}}}}{{2(1)}}\]\[x = \frac{{-5 \pm \sqrt{{25 - 8}}}}{2}\]\[x = \frac{{-5 \pm \sqrt{{17}}}}{2}\][/tex]

So, the solutions are:

[tex]\[x_1 = \frac{{-5 + \sqrt{{17}}}}{2}\]\[x_2 = \frac{{-5 - \sqrt{{17}}}}{2}\][/tex]

Thus,  [tex]\(x = \frac{{-5 + \sqrt{{17}}}}{2}\) or \(x = \frac{{-5 - \sqrt{{17}}}}{2}\). These are the solutions to the equation \(x^2 + 5x = -2\).[/tex]

Answer:

Step-by-step explanation:

so we are picking 40 blues from total number of buttons 120.

40 divided by 120 is 1 over 3.

Answer:

W = 4.646 ft

L = 9.292 ft

H = 3.097 ft

Step-by-step explanation:

Let's say the L is the length, W is the width, and H is the height.

The volume of the pool is:

V = LWH

The area of the pool is:

A = LW + 2LH + 2WH

L = 2W, so substituting:

V = (2W)WH

V = 2W²H

A = (2W)W + 2(2W)H + 2WH

A = 2W² + 4WH + 2WH

A = 2W² + 6WH

Solving for H in the first equation and substituting into the second:

H = V/(2W²)

A = 2W² + 3V/W

Find dA/dW and set to 0.

dA/dW = 4W − 3V/W²

0 = 4W − 3V/W²

4W = 3V/W²

4W³ = 3V

W = ∛(¾V)

V = 1000 gallons or 133.7 ft³.

W = ∛(¾(133.7 ft³))

W = 4.646 ft

So L = 9.292 ft and H = 3.097 ft.

Make sure your calculator is in Degree mode.

The horizontal distance from the wall to the base of the ladder is 6.3-foot and it can be determined by using trigonometric ratios.

Given that,

A 15-foot ladder leans against a wall and makes an angle of 65° with the ground.

We have to determine,

What is the horizontal distance from the wall to the base of the ladder?

According to the question,

Let, the horizontal length be x,

The length of the hypotenuse is 15-foot.

And the angle is 65 degrees.

Then,

The horizontal distance from the wall to the base of the ladder is,

[tex]\rm Cos\theta = \dfrac{Horizontal \ distance}{Perpendicular}\\\\Cos65 = \dfrac{x}{15}\\\\x = Cos65 \times 15\\\\x = 0.42 \times15\\\\x = 6.3 \ foot[/tex]

Hence, The horizontal distance from the wall to the base of the ladder is 6.3-foot.

  -10, -8, -6, -4

Step-by-step explanation:

Perhaps you want to know what they are.

The odd number between the middle two is their average value: -28/4 = -7.

The integers are -10, -8, -6, -4.

Answer: The even integers are -10, -8, -6 and -4

Step-by-step explanation:

Let the smallest of the even integers be represented by x, the other three will therefore be x +2, x +4 and x+6

Thus, x + (x+2) + (x+4) + (x+6) = -28

4x + 12= -28

Make x the subject of the equation

4x= -28 - 12

4x= -40

x = -10,

since the x = -10,

x + 2= -10 + 2= -8

x + 4= -10 +4 = -6

x + 6= -10 + 6= -4

Final answer:

The volume of a right rectangular prism made from 8 small cubes with an edge length of 1/5 inch each is 8/125 cubic inches.

Explanation:

The question asks for the volume of a right rectangular prism made up of 8 small cubes, with each cube having an edge length of 1/5 inch. To find the volume of the right rectangular prism, we must first understand the volume of a single cube, which is found by multiplying the length, width, and height of the cube. Since each side of a cube is equal, the volume of one cube is (1/5 inch) × (1/5 inch) × (1/5 inch), which equals 1/125 cubic inches.

Next, the volume of the entire prism, which consists of 8 such cubes, is calculated by multiplying the volume of one cube by 8. Therefore, the total volume of the prism is (1/125 cubic inches) × 8, which equals 8/125 cubic inches.

The total surface area is given by:

The base of the cylinder is a circle with radius 5cm, so its area is

[tex]A=\pi r^2=25\pi[/tex]

The lateral surface of the cylinder is a rectangle whose base is the circumference of the base circle, and whose height is the height of the cylinder. So, its area is

[tex]A=b\cdot h=2\pi r\cdot h = 10\pi\cdot 8=80\pi[/tex]

Finally, the surface of a sphere is given by

[tex]A=4\pi r^2[/tex]

so, half that surface will be

[tex]A=2\pi r^2=50\pi[/tex]

And the total surface area will be the sum of the three areas:

[tex]A=25\pi+80\pi+50\pi = 155\pi[/tex]

Answer:

Total surface area of the figure[tex]=486.7cm^2[/tex]

Step-by-step explanation:

Total surface area of the figure= Surface area of cylinder + Area of the top hemisphere

[tex]r= 5cm\\\\h= 8cm[/tex]

Area of the cylinder with the side walls and the the bottom:

          [tex]A=(2*\pi* r*h)+(\pi *r^2)[/tex]

             [tex]=(2*3.14*5*8)+(3.14*5*5)\\\\ =251.2+78.5\\\\ = 329.7 cm^2[/tex]

Area of the top hemisphere:

                                               [tex]2*\pi *r^2[/tex]

                               [tex]=2*3.14*5*5[/tex]
