Answer:
D, B, F
Step-by-step explanation:
$2 each pound
x= pounds
y= total cost
1 pound= $2
the $2 : constant
the number of pounds: variable
the equation is y=2x
1 pound: $2
2 pounds: $4
4 pounds: $8
5 pounds: $10
these also could be written as coordinates
the coordinates are (1,2),(2,4),(4,8),(5,10)
Answer:
Step-by-step explanation:
volume of cone=1/3×π×4²×10=160/3 π cm³
Answer:
-5
Step-by-step explanation:
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
0.1 is a rational number because it can be written as 
form.
So, we can write it as
so, it can be written as 
Hence, option 'a' is correct.
Answer:
D
Step-by-step explanation:
Calculating the volumes of both solids
Volume of a cube = s³ ( where s is the side length )
here s = 10, hence
V = 10³ = 10 × 10 × 10 = 1000 in³
Volume of a cylinder = area of base × height
Area of circular base = πr²
here r = 10 and h = 12, hence
V = π × 10² × 12 = 1200π ≈ 3769 .9 in³
The volume of the cylinder is greater than the volume of the cube → D
