Answer:
This is a numerical expression or D.
Step-by-step explanation:
It is not algebraic because it doesn't include unknown variables such as x or y
and it is not a numerical equation because equations have equal signs in them such as 5 + 6 = 11
Answer:
it is a numerical expression
Step-by-step explanation:
it is not an algebraic equation because there are no variables say, p or q or any other variables attached or unattached to its coefficients. And no equal sign attached to it.
it is not an algebraic expression.
it is not a numerical equation because it has no equal sign neither is it equating itself to another.
finally, it is a numerical expression because it only consists of numbers and has no equal sign. Or it is not equating to any other solution.
b. 5tan(25°)
c. 5/sin(25°)
d. sin(25°)/5
Answer:
b. 5tan(25°)
Step-by-step explanation:
The tangent function gives the ratio between the side opposite and the side adjacent to the angle. That is ...
tan(25°) = ?/5
Multiplying by 5 solves the equation:
? = 5·tan(25°)

Answer:
3
Step-by-step explanation:
To evaluate the expression 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):
Inside the innermost parentheses, we have:
3 - 25 ÷ 5
= 3 - 5
= -2
Now, the expression becomes:
20 - {3 × 8 - 5 - (-2)}
Next, perform the multiplication and subtraction inside the innermost braces:
3 × 8 = 24
5 - (-2) = 5 + 2 = 7
The expression becomes:
20 - {24 - 7}
Continue inside the braces:
24 - 7 = 17
Now, the expression becomes:
20 - 17
Finally, subtract:
20 - 17 = 3
So, the value of the expression is 3.
Following the steps of the BODMAS rule, the expression simplifies to -1.
The question involves arithmetic operations such as subtraction, multiplication, and division. The correct order of these operations is dictated by the BODMAS rule, which stands for Brackets, Orders (powers and square roots, etc.), Division and Multiplication (left-to-right), Addition and Subtraction (left-to-right).
According to this rule, begin by calculating within the deepest set of brackets: 25 ÷ 5 = 5. Your expression now becomes: 20 - {3 × 8 - 5 - (3 - 5)}, which simplifies to 20 - {3 × 8 - 5 - -2}. The next step is to calculate the multiplication: 24 - 5 - -2, which further simplifies to 20 - {24 - 5 + 2}, which becomes 20 - {21}, leading to a final result of -1.
