The mathematical statement given as 0.09 is 1/10 as much as 0.90 is true

The mathematical statement is given as:

0.09 is 1/10 as much as 0.90

To determine if the above statement is true, we start by representing the statement as an equation

So, we have

0.09 = 1/10 * 0.90

Express 1/10 as decimal

So, we have

0.09 = 0.10 * 0.90

Evaluate the product

So, we have

0.09 = 0.09

The above equation is true

Hence, the mathematical statement given as 0.09 is 1/10 as much as 0.90 is true

Determine if the following statement is true or false

The distance between two points A (-10, -7) and B(-8,1) will be equal to 8.2 units.

What do you mean by the distance between points ?

Distance between two points is the length of the line segment that connects the two locations in a plane.

It is given that the distance between points A (-10, -7) and B(-8,1) is to be calculated.

We can find out the distance by using the distance formula which is given by :

AB = [tex]\sqrt({x_{2} - x_{1})^2 + (y_{2}- y_{1})^2}[/tex]

AB = √ [( -8 -(-10)]^2 + [ 1 - (-7)]^2}

AB = √ (2² + 8²)

AB = √68

AB = 8.24 units

If we round off it to the nearest tenth then , hundredth place is less than 5 that meant 2 will be at the tenths place.

or

AB = 8.2 units.

Therefore , the distance between two points A (-10, -7) and B(-8,1) will be equal to 8.2 units.

Solving a system of equations we can see that the two numbers are 727 and 4

Let's define x as the 3-digit number and y as the one-digit number.

Then we know that the sum is equal to 731:

x + y = 731

And the product is equal to 2,908, then:

x*y = 2,908

So we have a system of equations:

x + y = 731

x*y = 2,908

Isolating x on the first equation gives:

x = 731 - y

Now we can replace that in the other equation to get:

(731 - y)*y = 2,908

Now we can solve this quadratic equation to find the value of y.

731*y - y^2 = 2,908

-y^2 + 731*y - 2,908 = 0

The solutions are:

y = (-731 ± √( 731^2 - 4*(-2,908)*(-1))/(-2)

y = (-731 ± 723)/-2

Now, y is an one digit number, then:

y = (-731 + 723)/-2 = 4

And x will be the 3 digit number:

x = 731 - x = 731 - 4 = 727

So the two numbers are 727 and 4

Answer:

you should cook it for 19 hours

Reason:

Subtract 3x from both sides. They cancel out and go away. The x term is fully eliminated and we're left with the equation 8 = 9, which is a false statement. Therefore, the original equation is always false regardless of what you pick for x. This is why there aren't any solutions.

Visually you can graph y = 3x+8 and y = 3x+9. You'll get parallel lines that never intersect. We need the lines to intersect if we wanted a solution point. Parallel lines have the same slope, but different y intercepts.

Because the system has no solutions, we consider the system inconsistent.

Answer:

Step-by-step explanation:

System of Linear Equations entered :

  [2]    2x + 5y = 1

Graphic Representation of the Equations :

   -4y + x = 20        5y + 2x = 1  

Solve by Substitution :

// Solve equation [1] for the variable  x

 [1]    x = 4y + 20

// Plug this in for variable  x  in equation [2]

  [2]    2•(4y+20) + 5y = 1

  [2]    13y = -39

// Solve equation [2] for the variable  y

  [2]    13y = - 39

  [2]    y = - 3

// By now we know this much :

   x = 4y+20

The interpretation of the beam on the wall is that when the function is undefined, the light is not shining completely on the wall and  and the function rate of changes are 55.236, 68.276, 110.473 and 289.221

The given parameter is the graph of the beam

From the graph, we can see that the beam does not shine on all parts of the wall.

It shines on some part and doesn't on other parts

This means that the function is undefined

Hence, the interpretation of the beam on the wall is that when the function is undefined, the light is not shining completely on the wall

To do this, we use the following computations:

[d(0.1) - d(0)]/[0.1 - 0] = [5.5236 - 0]/[0.1 - 0] = 55.236

[d(0.2) - d(0.1)]/[0.2 - 0.1] = [12.3512 - 5.5236]/[0.2 - 0.1] = 68.276

[d(0.3) - d(0.2)]/[0.3 - 0.2] = [23.3985 - 12.3512]/[0.3 - 0.2] = 110.473

[d(0.4) - d(0.3)]/[0.4 - 0.3] = [52.3206 - 23.3985]/[0.4 - 0.3] = 289.221

Hence, the function rate of changes are 55.236, 68.276, 110.473 and 289.221

Step-by-step explanation:

Antonio will save $113.4 after calculating using mensuration and buying from Pets Galore instead of Healthy pets.

As per the question statement, Antonio needs to buy 150 pounds of dog food for the local dog shelter. Healthy Pets, sells dog food in 50-pound bags for $85.95 per bag and Pets Galore sells one bag for $48.15

We are supposed to calculate the amount of money saved by Antonio if he buys 150 pounds of dog food from Pets Galore instead of from Healthy Pets.

Using concept of mensuration,

Quantity of dog food in one bag = 50 pounds

Quantity required of dog food = 150 pounds

Therefore number of bags required = 150/50 = 3

Price of dog food at Pets Galore per bag = $48.15

Total money to be paid to Pets Galore for 3 bags = $48.15*3  = $144.45

Total money to be paid to Healthy Pets for 3 bags = $85.95*3 = $275.85

Therefore money saved = $275.85 - $144.45  = $113.4
