Answer:
![d=7.8\ g/cm^3](https://tex.z-dn.net/?f=d%3D7.8%5C%20g%2Fcm%5E3)
Step-by-step explanation:
Given that,
The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm
Mass, m = 93.6 g
We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,
![d=\dfrac{m}{V}\\\\d=\dfrac{93.6}{4\times 2\times 1.5}\\\\d=7.8\ g/cm^3](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7Bm%7D%7BV%7D%5C%5C%5C%5Cd%3D%5Cdfrac%7B93.6%7D%7B4%5Ctimes%202%5Ctimes%201.5%7D%5C%5C%5C%5Cd%3D7.8%5C%20g%2Fcm%5E3)
So, the density of the steel is

Answer:$12.15
Step-by-step explanation:
Given
The regular price of an item ![\$81](https://tex.z-dn.net/?f=%5C%2481)
Maria gets a discount of ![85\%](https://tex.z-dn.net/?f=85%5C%25)
Amount paid after the discount is
![\Rightarrow 81(1-85\%)\\\Rightarrow 81(1-0.85)=85(0.15)\\\Rightarrow \$12.15](https://tex.z-dn.net/?f=%5CRightarrow%2081%281-85%5C%25%29%5C%5C%5CRightarrow%2081%281-0.85%29%3D85%280.15%29%5C%5C%5CRightarrow%20%5C%2412.15)
