Answer:
The answer is the first
Amie should have multiplied 54 by 2/3
Step-by-step explanation:
* Lets start with the rule of the volume of each solid
∵ Volume the sphere = 4/3 π r³
∵ Volume the cylinder = π r² h
∵ The radii and the heights of the sphere and the cylinder are equal
∴ The ratio between there volumes are
4/3 π r³ : π r² h
- Lets divide each part by π r²
∴ 4/3 r : h
∵ The height of the sphere = the diameter of it = 2r
∴ The height of the cylinder = 2r
∴ The ratio will be:
4/3 r : 2r
- Now divide each part by 2r
∵ (4/3)r ÷ 2r = 2/3
∵ 2r ÷ 2r = 1
∴ The ratio is 2/3 : 1
∴ The volume of the sphere = 2/3 the volume of the cylinder
∵ The volume of the cylinder = 54 m³
∴ The volume of the sphere = 2/3 × 54 = 36 m³
∴ The answer is Amie should have multiplied 54 by 2/3
To factor the expression you need to find the greatest common factor of the terms. The greatest common factor (GCF) is the highest number that will be into both terms. Since there's nothing that will fit into both x and y, you'll only need to find the GCF of the coefficients.
16x + 40y To start, list the factors of both numbers
16: 1, 2, 4, 8, 16
40, 1, 2, 4, 5, 8, 10, 20, 40
You can see that 8 is the highest number that will go into 16 and 40. So, you can pull the 8 out of the expression.
8(2x + 5y)
This is a quadratic equation:
y = a x² + b x + c, a > 0 ( opening upward )
The zeroes are: ( - 1 , 0 ) and ( 4, 0 ).
y = a ( x - x 1 ) ( x - x 2 )
y = a ( x + 1 ) ( x - 4 )
y = a ( x² - 4 x + x - 4 )
y = a ( x² - 3 x - 4 )
Answer:
2y^2 + 18x
Step-by-step explanation:
It’s b what u need to do is 13x9 which is 117 then divide it by 2 which is 58.5
