Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
<h3>What is a mathematical expression?
</h3>
A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.
Mathematical expressions generally have symbols like:
- Add +
- Subtraction -
- Multiplication ×
- Division ÷
- Exponent
- Equal =
- Parentheses ()
According to the above, some examples of mathematical expressions are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

One tenth is 0.1. Therefore, the answer has to be 2.x. Since 4 is less than 5, the 2 remains the same. The answer is 2.2.
It is a
9/4=2.25*2=4.5
Hope it helps :)
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
Answer:
The angle between [A_F] and the base of the cone = 68.2°
The area of the base of the cone ≈ 12.57 m²
Step-by-step explanation:
The given parameters are;
The height of the cone = 5 m
The base radius of the cone = 2 m
The angle which the A
C = 120°
Therefore, we have;
The angle between [A_F] and the base of the cone = The angle between [CF] and the base of the cone
The angle between [CF] and the base of the cone = tan⁻¹(5/2) = tan⁻¹(2.5) ≈ 68.2°
∴ The angle between [A_F] and the base of the cone = The angle between [CF] and the base of the cone = 68.2°
The angle between [A_F] and the base of the cone = 68.2°
The area of the base of the cone = π × r² = π × 2² = 4·π ≈ 12.57
The area of the base of the cone ≈ 12.57 m².
