Find the area of the shaded region.

Answer:

10,000

Step-by-step explanation:

We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.

1 m = 100 cm

10 m = 1000 cm

40 m = 4000 cm

area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2

area of tile = s^2 = (20 cm)^2 = 400 cm^2

number of tiles = 4,000,000/400 = 10,000

Answer: 10,000 tiles

Answer:

(-6, 6)

Step-by-step explanation:

Let the coordinates of point B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid-point formula:

[tex] - 5 = \frac{ - 4 + x}{2} \\ - 5 \times 2 = - 4 + x \\ - 10 + 4 = x \\ x = - 6 \\ \\ 4 = \frac{2 + y}{2} \\ 4 \times 2 = 2 + y \\ 8 = 2 + y \\ 8 - 2 = y \\ y = 6 \\ \\ (x, \: \: y) = ( - 6, \: \: 6)[/tex]

Thus, the coordinates of point B are (-6, 6).

The coordinate of B is (-6, 6) if the midpoint of AB is M(-5, 4) and the coordinates of A are (-4, 2),

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

We have:

The midpoint of AB is M(-5, 4).

The coordinate of A is (-4, 2)

Let the coordinate of B is (x, y)

By using the midpoint property:

(-4+x)/2 = -5

-4 + x = -10

As we know, the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

-4 + x = -10

It is a linear equation in one variable:

x = -6

Similarly for y:

(2+y)/2 = 4

2 + y = 8

y = 6

The coordinate of B is (-6, 6)

Thus, the coordinate of B is (-6, 6) if the midpoint of AB is M(-5, 4) and the coordinates of A are (-4, 2),

Answer: 25 cents

Step-by-step explanation:

24 ounces = 6 dollars. Divide 24 by itself to get 1 ounce. Then, divide 6 by 24 to get 25 cents.

The unit price per ounce is 25 cents.

It is required to find the unit price per ounce.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

We know that,

24 ounces = 6 dollars.

Divide 24 by itself to get 1 ounce.

1 ounces = 6/24 dollars.

1 ounces = 1/4 dollars.

1 ounces = 1/4*100 cents

1 ounces =25 cents.

Therefore, the unit price per ounce is 25 cents.

Answer: x=38

Step-by-step explanation:

x+(-15)=23

x-15=23

+15  +15

x=38

When there is a positive and negative sign the negative sign cancels the positive sign.

Answer:

38

Step-by-step explanation:

23+15=38 because in order to get 23 from -15 a negative number you need to have 38 to silence the -15.

The correct answer is A. Number of hours worked

Explanation:

In the equation presented, the number of hours worked is the only factor that varies, it is expected the plumber has to work a different number of hours depending on each situation and this affects the final cost as the number of hours is multiplied by $25 (cost of one hour). On the other hand, factors such as the house call charge or the price of an hour for labor are fixed and do not change.

Moreover, in equations, the factor that changes and can affect others is known as the independent variable. This means the number of hours can be classified as the independent variable because this is not fixed and affect other variables including the total cost.

Answer:

285.2

Step-by-step explanation:

Answer:

$1900

Step-by-step explanation:

Starting from the equation of simple interest, which is defined as follows:

I = P * r * t

Being I the interest, P the value of the product, r the interest rate and t would be time.

We want to know the price of the product, therefore, solving the equation we have:

P = I / r * t

We know each other's values so we replace:

P = 1026 / (0.135 * 4)

P = $ 1900 was the value of the refrigerator Jaime bought

Answer:

$1900

Step-by-step explanation:

Starting from the equation of simple interest, which is defined as follows:

I = P * r * t

Since I is the interest, P the value product, r the interest rate and t would be time

We want to know the price of the product, therefore, solving the equation we have:

P = I / r * t

We know each other's values so we replace:

P = 1026 / (0.135 * 4)

P = $1900 was the value of the refrigerator Jaime bought.

Answer:

c. The square root of 12 is between 4 & 5.

Step-by-step explanation:

a. The square root of 112 is between 10 & 11

i. Find the squares of 10 & 11

10² = 100

11² = 121

Because 100 < 112 < 121, we know the square root of 112 is between 10 & 11

b. The square root of 180 is between 13 & 14

i. Find the squares of 13 & 14

13² = 169

14² = 196

Because 169 < 180 < 196, we know that the square root of 180 is between 13 & 14

c. The square root of 12 is between 4 & 5.

i. Find the squares of 4 & 5

4² = 16

5² = 25

Because 12 < 16 & 25, we know that the square root of 12 is not between 4 & 5.

d. The square root of 5 is between 2 & 3.

i. Find the squares of 2 & 3

2² = 4

3² = 9

Because 4 < 5 < 9, we know that the square root of 5 is between 2 & 3.

Answer:

[tex]x -3e^{-x} + C[/tex]

Step-by-step explanation:

Given the integral [tex]\int\limits {\dfrac{e^{x}+3}{e^x} } \, dx[/tex], we are to evaluate it. Note that sum of integral is equal to the integral of its individual sum as  shown;

[tex]\int\limits {\dfrac{e^{x}+3}{e^x} } \, dx = \int\limits {\dfrac{e^{x}}{e^x} } \, dx + \int\limits {\dfrac{3}{e^x} } \, dx[/tex]

[tex]= \int\limits 1\, dx + 3\int\limits {e^{-x} \, dx \\\\[/tex]

[tex]= x + 3(-e^{-x})\\\\= x -3e^{-x} + C[/tex]

Hence the value of the evaluated integral is [tex]x -3e^{-x} + C[/tex] where C is the constant of integration.

Answer:

Sammy has the greatest amount.

Step-by-step explanation:

I figured that out because half of 1,000,000 is 500,000 , and Laila had 1,000,000 but gave Sammy half of that money , and Sammy had already started out with 90,000 , So 500,000 + 90,000 = 590,000 . So that means Laila is stuck with the 500,000 while Sammy has the 90,000 she started off with and the 500,000 Laila gave her .

Answer:

the answer 7/5

Step-by-step explanation:

Convert to a mixed number by placing the numbers to the right of the decimal over 10. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
