The length of a rectangle is five times its width.
If the perimeter of the rectangle is 72 cm, find its area.

Answers

Answer:

180 cm²

Step-by-step explanation:

x = length

y = width

perimeter of a rectangle is the sum of all sides, so, 2×length plus 2×width.

x = 5y

72 = 2x + 2y

using the first equation as substitute in the second equation

72 = 2×(5y) + 2y = 10y + 2y = 12y

y = 6 cm

x = 5y = 5×6 = 30 cm

area = x × y = 30 × 6 = 180 cm²

iii. Write an expression to determine how many times as long the room is than 3 feet.
Preview

Answers

The dimension of a room is the length and width of the room.

The length of the room in yard is L/3An expression for the length of the room in unit of 3ft is 3LThe room is longer than 3 feet, in L times

From the question, we have:

[tex]L \to[/tex] Number of feet

(a) An expression for the length of the room in yards

In standard unit of conversion

[tex]1ft = \frac{1}{3} yd[/tex]

Multiply both sides by L:

[tex]L \times 1ft = L \times \frac{1}{3} yd[/tex]

[tex]L\ ft = \frac{L}{3} yd[/tex]

Hence, the length of the room in yard is L/3

(b) An expression for the length of the room in unit of 3ft

In (a), we have:

[tex]L \to[/tex] Number of feet

To calculate the length in units of 3 feet, we simply multiply L by 3

[tex]Unit = 3 \times L[/tex]

[tex]Unit = 3L[/tex]

An expression for the length of the room in unit of 3ft is 3L

(c) How many times longer the room is, than 3ft.

In (b), we have:

[tex]Unit = 3L[/tex]

The number of times (n) the room is longer than 3 ft is:

[tex]n = Unit \div 3[/tex]

[tex]n = 3L \div 3[/tex]

[tex]n = L[/tex]

The room is longer than 3 feet, in L times

The hypotenuse of a right triangle is 10 meters and its
legs measure x and x + 2. How long are the legs?

Answers

Solution :

Let's solve by using Pythagoras theorem,

[tex] \hookrightarrow \: (10) {}^{2} = {(x})^{2} + (x + 2) {}^{2} [/tex]

[tex] \hookrightarrow \: 100 = {x}^{2} + {x}^{2} + 4x + 4[/tex]

[tex] \hookrightarrow \: 100 - 4 = 2 {x}^{2} + 4x[/tex]

[tex] \hookrightarrow \: 96 = 2 {x}^{2} + 4x[/tex]

[tex] \hookrightarrow \: 2 {x}^{2} + 4x - 96 = 0[/tex]

[tex] \hookrightarrow \: 2( {x}^{2} + 2x - 48) = 0[/tex]

[tex] \hookrightarrow \: {x}^{2} + 2x - 48 = 0[/tex]

[tex] \hookrightarrow \: {x}^{2} + 8x - 6x - 48 = 0[/tex]

[tex] \hookrightarrow \: x(x + 8) - 6(x + 8) = 0[/tex]

[tex] \hookrightarrow \: (x + 8)(x - 6) = 0[/tex]

now there are two cases

Case 1 : when (x + 8) = 0

[tex] \hookrightarrow \: x + 8 = 0[/tex]

[tex] \hookrightarrow \: x = - 8[/tex]

but the value of x can't be negative, since side of a triangle isn't a negative value .

Case 2 : when (x - 6) = 0

[tex] \hookrightarrow \: x - 6 = 0[/tex]

[tex] \hookrightarrow \: x = 6[/tex]

therefore the measure of other two sides are :

[tex] \hookrightarrow \: x = 6 \: units[/tex]

[tex] \hookrightarrow \: x + 2 = 6 + 2 = 8 \: units[/tex]

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n"  ways; then the two events in succession can occur in m × n  ways.

Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.

Pencil = 21

Pencil holder = 3

Therefore, we will do as 21 divided by 3

21/3 = 7

Hence, there are 7 pencils in each pencil holder.

What is Simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, the values of a and b are 9/11 and 7/10 respectively

thus,

ab = 9/11 * 7/10

simplifying it

ab = 63/110

Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10
