Answer:
Answer: (√3)/2
Step-by-step explanation:
[tex] \sin(35 \degree) \cos(25\degree) + \cos(35\degree) \sin(25\degree) \\ [/tex]
from trigonometry identities:
[tex] \sin(a + b) = \sin(a) \cos(b) + \cos(a) \sin(b) \\ [/tex]
a » 35°
b » 25°
Therefore;
[tex] = \sin(35\degree + 25\degree) \\ = \sin(60\degree) \\ \\ = \frac{ \sqrt{3} }{2} [/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

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 timesFrom 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
