Answer:
6in²
Step-by-step explanation:
Given that :
Base of right angle triangle = 3
Height of right angle triangle = 4
Area of a triangle = 1/2 * base * height
Area of triangle = 1/2 * 4 * 3
Area of triangle = 2 * 3
Area of triangle = 6in²

Answer:
5/4
Step-by-step explanation:
9a + 2b = 5a - 7b
Bringing like terms to one side of the equation,
9a - 5a = 7b - 2b
4a = 5b
By cross multiplication,
a/b = 5/4

Answer:
2500 kg/m³
Step-by-step explanation:
Density of a material is the ratio of mass and volume of that material.
The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)
Given density as 2.5 g/cm³ , convert to kg/m³
Formula is;
1g/cm³ = 1000 kg/m³
2.5 g/cm³=? cross-multiply
=2.5×1000 = 2500 kg/m³
