what are the pros and cons of fit lines and equations?​

Answer:

[tex]x=\frac{\sqrt{2}}{2}[/tex]

Step-by-step explanation:

The given triangle is an isosceles right triangle, meaning that the 45-45-90 triangle side rule applies. The 45-45-90 triangle side rule states that the two legs (sides that are adjacent to the right angle) are congruent, and the hypotenuse (the side opposite the rights angle) is equal to the leg times the square root of two. Using this property, one knows that the leg is equal to the hypotenuse divided by the square root of two. In this problem, the hypotenuse is equal to (1), and the leg is equal to (x). Therefore, one can say,

[tex]x = \frac{1}{\sqrt{2}}[/tex]

Rationalize the denominator,

[tex]\frac{1}{\sqrt{2}}*\frac{\sqrt{2}}{\sqrt{2}}\\\\\frac{\sqrt{2}}{2}[/tex]

Answer:

Step-by-step explanation:

a² + b²  = c²     look familiar?  it is the Pythagorean theorem

both side are the same length since both angles are the same some sort of Isosceles triangle rule I think    so side 1 = x   side 2 = x and  hypotenuse = 1

x² + x²  = 1²

   2x²   = 1

     x²   = 1/2

     x     =     √(1/2)      the denominator is  NOT rational in this FORM

     x    =    √1 / √2       multiple the numerator and the denominator by √2

     x    =    1 (√2) / (√2)(√2)

     x    =   √2 / √2²

     x    =   √2 / 2        finding a rational denominators means nothing

                                  just do more work and more typing for me,

                                  a silly MATH rule

  x = √2/2   =  0.7071        x = √(1/2)  = √(0.5)   =  0.7071   the SAME Number

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333

Answer: Nolan worked 4 hours, and Mia worked 8 hours

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of hours Nolan worked.

Let y represent the number of hours Mia worked.

Mia worked twice as many hours as Nolan. This means that

y = 2x

Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Together, Nolan and Mia ironed 380 shirts between them. This means that

25x + 35y = 380 - - - - - - - - - - - - - -1

Substituting y = 2x into equation 1, it becomes

25x + 35 × 2x = 380

25x + 70x = 380

95x = 380

x = 380/95

x = 4

y = 2x = 2 × 4

y = 8

Answer:

y=5x+100

Step-by-step explanation:

equation of a line is y=mx+c

where m=slope c=y-intercept

Answer: 20 feet

Step-by-step explanation:

This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.

Solve with Pythagoras rule:

c² = a² + b²

c = hypotenuse

a= length

b = height

29² = 21² + b²

841 = 441 + b²

b² = 841 - 441

b² = 400

b = √400

b = 20 feet

Step-by-step explanation:

Answer:

They would have built 84 cars

Step-by-step explanation:

From the question, they have already built 9 cars

Now, the hourly production rate is 15 cars per hour;

So therefore, in 5 hours, total that would have been built excluding the initial 9 will be;

15 * 5 = 75 cars

Now, let us add the initial 9

we have this as 9 + 75 = 84 cars

Answer:

4

Step-by-step explanation:

11s+9t=116

5s+9t=92

Minus bottom equation from the top

6s+0=24

divide 6 on both sides

s=4

Answer:

Student B

Step-by-step explanation:

You know because:

The common factor between 3 and 6 is 3.

You can factor 2 x's from both parts and 2 y's.

Therefore, it would be

3x^2y^2.

Answer:

Density = 8g/cm³

Step-by-step explanation:

Density = Mass/Volume

Given the following

Mass = 960g

Volume = 120cm^3

Substitute

Density = 960g/120cm^3

Density = 8g/cm³

Answer:

A

Step-by-step explanation:

Answer d

because if we use option a then second part of the question will not satisfy

if we use option b then first part will not satisfy

hence.this question has no solution

Given:

A figure of a circle. A secant and tangent of the given circle.

To find:

The correct equation.

Solution:

According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.

Using intersecting tangent secant theorem, we get

[tex]6^2=x(x+5)[/tex]

It can be written as

[tex]x(x+5)=6^2[/tex]

The required equation is [tex]x(x+5)=6^2[/tex].

Therefore, the correct option is B.

Answer:

[tex]d=1.28\times 10^{-6}\ g/cm^3[/tex]

Step-by-step explanation:

The mass of a bag of sugar, m = 1 kg = 0.001 g

Length of bag, l = 9.2 cm

Width of bag, b = 6 cm

Height of the bag, h = 14.1 cm

We need to find the density of the sugar bag.

Density = mass/volume

So,

[tex]d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3[/tex]

So, the density of the bag is [tex]1.28\times 10^{-6}\ g/cm^3[/tex].

Answer:

the answer is 60

Step-by-step explanation:

Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.

Answer:

2 3/4

Step-by-step explanation:

2=2

.75= 3/4

Example 75 cents is equal to 3 quarters

[tex]2 \frac{3}{4} [/tex]

Because 2.75 =

[tex] \frac{11}{4} [/tex]

And

[tex] \frac{11}{4} = 2 \frac{3}{4} [/tex]

Answer:

1,2,3 have to equal 180 so 90+50 = 140 and 180 subtract 140 = 40 degrees for 1. 3 and 6 are the same and 1 and 4 are the same 4 is 40degrees

Answer:

the longest side is AC

Step-by-step explanation:

The longest side will be opposite the largest angle.

4x+(2x-6) + (4x-4) = 180 (all triangle interior angles add up to 180 degrees)

simplify:

10x - 10 = 180

10x = 190

c= 19

angle B = 4(19) = 76 degrees

angle A = 2(19) - 6 = 32 degrees

angle C = 4(19) - 4 = 72 degrees

so the longest side is AC

We are given two functions.

[tex]f(x)=x-4\\g(x)=-x-2[/tex]

The point that represents the equation [tex]f(x)=g(x)[/tex], will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for [tex]x[/tex].

[tex]f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1[/tex]

Now that we are given the x value, we can plug this value back into either equation and solve for the y value.

[tex]f(1)=1-4\\f(1)=-3[/tex]

The point of intersection will be [tex](1,-3)[/tex].

Hope this helps!

Answer:

A.y=|x|+7

Step-by-step explanation:

Answer:

1). No, symbol won't be reversed

2.) No, symbol won't be reversed

3.) yes, symbol will be reversed

4.) No, symbol won't be reversed

Step-by-step explanation:

1.)

-10.5 < 3a

-10.5 /3 < 3a /3

-3.5 < 3 (No)

2.)

b/6 ≤ 7

Multiply both sides by 6

b/6 * 6 ≤ 7 * 6

b ≤ 42 (No)

3.)

-4.5c > 9

Dibide both sides by - 4.5

-4.5c / - 4.5 > 9/-4.5

c < 2 (yes)

4.)

–21/5 ≤ –5/2d

Multiply both sides by 2/5

-21/5 * 2/5 ≤ - 5/2d * 2/5

-21/2 ≤ - d

21/2 ≤ d (No)
