Answer:

In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.

We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.

To multiply two 2-digit numbers, using the area model, follow the given steps:

Write the multiplicands in expanded form as tens and ones.

For example, 27 as 20 and 7, and 35 as 30 and 5.

Draw a 2 × 2 grid, that is, a box with 2 rows and 2 columns.

Write the terms of one of the multiplicands on the top of the grid (box). One on the top of each cell.

On the left of the grid, write the terms of the other multiplicand. One on the side of each cell.

Write the product of the number on the tens in the first cell. Then write the product of the tens and ones in the second and third cell. Write the product of the ones in the fourth cell.

write the product in the cell

Finally, add all the partial products to get the final product.

Here, for example, the area model has been used to multiply 27 and 35.

area model multiplication

Let us see how to find the product of 3-digit number by a 2-digit number using the area model.

Find the Product using Area Model

Let us now use the area model for the division. Here, we divide 825 by 5.

Area Model Division 1

Area Model Division 2

Fun Facts

The area model is also known as the box model.

The area model of solving multiplication and division problems is derived from the concept of finding the area of a rectangle. Area of a rectangle = Length × Width.

Hi there!

[tex]\large\boxed{u + xy = 98}[/tex]

We can do substitution to solve.

We are given the values of all of the letters, so:

u = 18

x = 10

y = 8

Substitute:

(18) + (10)(8)

Use the order of operations:

18 + 80 = 98

Step-by-step explanation:

u + xy

make u = 18

x = 10

y = 8

18 + 10 × 8

18 + 80

= 98

Answer:

y = - [tex]\frac{2}{3}[/tex] x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (- 4.5, 0 ) ← coordinates of intercepts

m = [tex]\frac{0-(-3)}{-4.5-0}[/tex] = [tex]\frac{0+3}{-4.5-0}[/tex] = [tex]\frac{3}{-4.5}[/tex] = - [tex]\frac{2}{3}[/tex]

The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = - [tex]\frac{2}{3}[/tex] x - 3 ← equation of line

A. 4.19 yd³

Step-by-step explanation:

Volume of a sphere = 4/3πr³

V = 4/3 ( 3.14) (1³)

= 4/3 ( 3.14) (1)

= 4.19 yd³

Answer:

[tex]A\approx 4.19\ yd^2[/tex]

Step-by-step explanation:

The following formula can be used to find the volume of a sphere,

[tex]A=\frac{4}{3}(\pi)r^3[/tex]

Where (r) represents the radius of the sphere or the distance from the center of the sphere to its outer edge. The term ([tex]\pi[/tex]) represents the numerical constant ([tex]3.1415...[/tex]). In this problem, one is given that the radius of the sphere is (1). Substitute this value into the formula and simplify to solve,

[tex]A=\frac{4}{3}(\pi)r^3[/tex]

[tex]A=\frac{4}{3}(\pi)(1)^3[/tex]

[tex]A=\frac{4}{3}(\pi)1[/tex]

[tex]A=\frac{4}{3}(\pi)[/tex]

[tex]A\approx \frac{4}{3}*3.14[/tex]

[tex]A\approx \frac{12.56}{3}[/tex]

[tex]A\approx 4.19\ yd^2[/tex]

Answer:

Step-by-step explanation:

2x + 3y = 6

2x = 6-3y

x = (6-3y)/2

x - 3y = 9

(6-3y)/2 -3y = 9

(6-3y)/2 -6y/2 = 9

(6-9y)/2 = 9

6 - 9y = 9×2

-9y = 18-6

y = 12/-9

y = -4/3

2x + 3y = 6

2x + 3(-4/3) = 6

2x -4 = 6

2x = 6+4

2x = 10

x = 10/2

x = 5

Therefore x = 5 and y = (-4/3)

Answer:

x = 5; y = -4/3

Step-by-step explanation:

One equation has 3y. The other equation has -3y. Add the equations to eliminate y and solve for x.

     2x + 3y = 6

(+)     x - 3y = 9

---------------------

      3x        = 15

x = 5

2x + 3y = 6

2(5) + 3y = 6

3y + 10 = 6

3y = -4

y = -4/3

Answer: x = 5; y = -4/3

Answer: 9 (2 mark question) and 18 (5 marks questions)

Therefore 5 mark question = 2x

ATQ

⇒5(2x)+2(x) = 108

⇒10x+2x =108

⇒12x = 108

⇒x = 108/12

⇒x = 9

Total two mark questions are 9 and 5 mark questions are 18.

Answer:

  30 gallons

Step-by-step explanation:

Let c represent the capacity of the container. Then we have ...

  2/5c + 8 = 2/3c

Multiplying by 15 clears the fractions:

  6c +120 = 10c

  120 = 4c . . . . . . . . subtract 6c

  30 = c . . . . . . . . . . divide by 4

The container can hold 30 gallons.

_____

Additional comment

Often, you are told to "clear fractions" first when solving equations that involve them. Here, you can work directly with the fractions, if you like.

  8 = (2/3c) -(2/5c) = 4/15c . . . . . find the difference of the fractions

  8(15/4) = c = 30 . . . . . . . . . . . . . multiply by its inverse

Given the data provided, it follows that the farmers must wait for 26 days before feeding the hay to cows.

The term half life is defined as the time taken for half of the original amount of the radioactive sample to remain.

Now we know that;

half life = 8 days

Original amount = No

Amount left after t days = 0.1No

time taken = t days

Hence;

0.693/8 = 2.303/t log (No/0.1No)

0.087 = 2.303/t

t = 2.303/0.087

t = 26 days

Answer:

D. (0, 3)

Step-by-step explanation:

Interval of function f(x) is sometimes negative and sometimes positive.

The function interval is said to be positive if the value of the function f (x) increases with an increase in the value of x. In contrast, the function interval is said to be negative if the value of the function f (x) decreases with the increase in the value of x.

Given function,

f(x) = (2x – 1)(3x + 5)(x + 1),

Zeros of function,

x = 1/2 = 0.5

x = -5/3 = - 1.6667

x = -1

From the graph

Interval of function is negative between -∞ < x < -1.6667

Interval of graph is positive between -5/3 < x < -1

Interval of function is negative between -1 < x < 0.5

Interval of graph is positive 0.5 < x < ∞

Hence, f(x) has sometimes positive interval and sometimes negative interval.
