The addition according the place value is 12.39

The value of each digit in a number is known as place value. Every digit in a number has a distinct value depending on where it is located. The value of a digit depends on its location in the number, which might result in a number having two comparable digits with distinct values.

Place value refers to how much a digit is worth in relation to where it is in a number, such as the ones, tens, hundreds, and so on. For instance, 5 in 3458 has a place value of 5 tens, or 50. However, 5 thousands, or 5,000, is used to represent the place value of 5 in 5781. Understanding that a digit can have the same value regardless of where it appears in the number is crucial.

Given:

Eli used the place value strategy to add the numbers 4.69 and 7.7.

So, to add using place value strategy we use place value to break the addends into tens and ones.

Now, we add the tens and ones individually to find the whole sum.

So, breaking 4.69

at ones = 4

at tenth = 6

at hundredth = 9

In 7.7

at ones= 7

at tenth = 7

at hundredth = 0

Now, adding according to the place value

=(0 + 9 ) x 1/100 + (7 + 6) x 1/10 + (4 +7) x1

=9/100 + 13/10 + 11

=0.09 + 1.3 + 11

=12.39

By considering the areas of the two rectangles, we have shown that 2x² - 5x - 18 = 0

The value of length AB is 4.5 cm

From the question, we are to show that 2x² - 5x - 18 = 0

From the given information,

The total area of the compound shape ABCDEF is 36 cm²

That is,

Total area = 36 cm² = Area of small rectangle + Area of big rectangle

From the given diagram, we can write that

Area of small rectangle = x(x -4)

Area of small rectangle = x² - 4x

and

Area of big rectangle = (2x + x)(x -2)

Area of big rectangle = 3x(x - 2)

Area of big rectangle = 3x² - 6x

∴ 36 = x² - 4x + 3x² - 6x

36 = 4x² -10x

4x² -10x - 36 = 0

Divide through by 2

2x² - 5x - 18 = 0

Thus, we have shown that 2x² - 5x - 18 = 0

Now, we are to determine the value of length AB

The value of length AB is x cm.

Therefore, we will solve for x

From,

2x² - 5x - 18 = 0

2x² + 4x - 9x - 18 = 0

2x(x + 2) -9(x + 2) = 0

(2x - 9)(x + 2) = 0

2x - 9 = 0 OR x + 2= 0

2x = 9 OR x = -2

x = 9/2 OR x = -2

x = 4.5 OR x = -2

Since x cannot be negative, the value of x is 4.5

Thus,

AB is 4.5 cm

The linear function that contains the point (-4, -3) and is perpendicular to the line 4x + 5y = 15 is given by:

y = 5/4x + 2.

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which:

When two lines are perpendicular, the multiplication of their slopes is of -1, hence, considering the line is perpendicular to 4x + 5y = 15, we have that:

5y = 15 - 4x

y = 3 - 4/5x

Then:

-4/5m = -1

m = 5/4

Hence the rule is:

y = 5/4x + b

When x = -4, y = -3, hence the intercept b is found replacing these points into the equation as follows:

-3 = 5/4(-4) + b

-3 = -5 + b

b = 2.

Hence the equation is:

y = 5/4x + 2.

Both perpendicular equations are graphed at the end of the answer.

The temperature when the plane reaches an altitude of 4,000 will be 560°F.

It should be noted that temperature simply means the degree of hotness and coldness of a body.

In this case, there is a 14°F drop in temperature for every thousand feet that an alplane climbs into the sky.

Since the the temperature on the ground is 616, the temperature when the plane reaches an altitude of 4,000 will be:

= 616 - 14(4000/1000)

Answer:

-71

Step-by-step explanation:

−|62| is equal to -62, and -71 is less than -62.

the distance between the point H (- 2, 2) and point I (6, 2) is 8 units.

We are given the coordinates of the point as:

H = (- 2, 2)

I = (6, 2)

We need to find the distance between the two points.

We get that:

x₁ = - 2

y₁ = 2

x₂ = 6

y₂ = 2

Distance formula is given as:

Distance = √(y₂ - y₁)² + (x₂ - x₁)²

Substituting the values in the formula, we get that:

D = √(2 - 2)² + (6 + 2)²

D = √ 0² + 8²

D = √8²

D = 8 units.

Therefore, the distance between the point H (- 2, 2) and point I (6, 2) is 8 units.

   x = [n ⁄ (n+m)] (x₂ - x₁) + x₁  and y = [n ⁄ (n+m)] (y₂ - y₁) + y₁

Given:

For this problem, n = 2 and m = 2 since (2 ⁄ (2+2) = 2 ⁄ 4,  ( x,₁ y₁) =(-2, 5) and ( x₂, y₂) = (4, 9)

Where n and m are both positive integers, [n (n+m)] is the required distance ratio from the beginning position, (x₁, y₁)  are the coordinates of one endpoint, and (x₂, y₂) are the coordinates of the other endpoint.

x = [n ⁄ (n+m)] (x2 - x1) + x1

  = (2/4 ) (4 - (-2)) + (-2)

  =  (2/4 ) (4 + 2) + (-2)

  = (2/4 ) × 6 + (-2)

  =  3 - 2 = 1

y = [n ⁄ (n+m)] (y2 - y1) + y1

  =  (2/4 ) (9 - 5) + 5

With the annual interest of 1%, the total saving after 5 years is $6060.

Interest:

Interest is the amount for a particular principal amount of money at some rate of interest.

Given,

You earn $100 per month and want to save 10% in a savings account.

Here we have to use the savings calculator to find out how much your total savings would be in 5 years if your account has an annual interest rate of 1%.

Through the given details we have identified that,

Monthly earning = $100

Saving per month = 10%

So, in amount it can be

=> 100 x 10/100 = $10

So, for one year the saving without interest is

=> 10 x 12 = 1200

So, When we add the interest of 1% for the year,

Then the interest amount for one year will be,

=> 1200 x 1/100 = 12

So, the total amount including interest for one year,

=> 1200 + 12 = 1212

So, the savings after 5 years will be,

=> 5 x 1212

=> 6060.

Therefore, the total saving amount after 5 years is $6060.
