Answer:
<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>
Step-by-step explanation:
To find the mass in kg we must first convert the density from g/cm³ to kg/m³
That's 7.5 g/cm³ = 7500kg/m³
Density = mass / volume
Volume of block = 1.5 × 0.4 × 0.25
= 0.15m³
mass = Density × volume
= 7500 × 0.15
<h3>= 1125 Kg</h3>

Answer:
D)
Step-by-step explanation:
Coefficient of x is -3/2 and so multiply the whole equation by 2
3x + 2y = -8
So width is l-16, l being the length. perimeter is 2w+2l=98. substitute w for l-16 for 2(l-16)+2l=98. Now, distribute to get 2l-32+2l=98. Add 32 to both sides for 2l+2l=130. then, 4l=130. divide both sides by four, so the length is 32.5. plug this into the original perimeter equation for 2w+2(32.5)=98. Again, distribute and subtract so your equation is 2w=33. Divide both sides by 2 so your width is 16.5
so width is 16.5 cm, and length is 32.5 cm
hope this helps!
