Answer:
123.948 km²
Step-by-step explanation:
We can use the equation: <em>AΔ = 1/2*ab*sinθ</em>, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.
Plugging in the numbers we know, we get: <em>AΔ = 1/2*22*24*sin(28°)</em>
Simplify: <em>AΔ = 264*.4695</em> (0.4695 is approximately sin(28°))
Simplify: 123.948 km²
Let the cost of soap be x,
cost of razors = x + 2.5
total cost = 2x + 2.5
2x + 2.5 = 5.5
2x = 3
x = 1.5
cost of razors = 1.5 + 2.5
= 4
The cost of the packet of razors and bar of soap is £4.00 and £1.50 respectively.
Answer:
125 cm^3
Step-by-step explanation:
To calculate this volume, we make use of the formula for calculating the volume of a cube.
Mathematically, this is equal to L^3 where L is the length of a side of the cube.
plugging the value of 5 into the equation, the volume will be 5 * 5 * 5 = 125 cm^3
