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
$68 is discounted from the regular price.
To find this, you first divide 80% by 100 to get 0.8 (the decimal form of the percentage). Then, simply multiply 0.8 by 85 (or vise verse) to get $68. Since the question is asking for how much is discounted from the regular price, the final answer would be $68.

A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct
<h3>Set theory</h3>
Set is defined as the arrangement of elements. They can be represented using the venn diagram.
Given the following sets
U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}
B={x: x^2>20} = {x >± 20}
From the set, can see that A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct

Let the length of river D be x
then the lenght of river C will be 200+x
but,
lenght of river C+lenght of river D=5580
x+x+200=5580
2x=5380
x=2690
Therefore lenght of river D is 2690 and that of C is 2890
