Answer:
First one can
Second one can not
Step-by-step explanation:
13² = 5² + 12²
169 = 25 + 144
169 = 169 is a true statement
15² = 11² + 12²
225 = 121 + 144
225 = 265 is a false statement
So, not a right angle triangle
Answer:
Step-by-step explanation:
If two ratios make a proportion then it can be shown as:
Let's verify the answer choices with this method
A. 1/4 and 5/25
- 1*25 = 4*5
- 25 = 20, incorrect, not a proportion
B. 1/4 and 7/24
- 1*24 = 4*7
- 24 = 28, incorrect, not a proportion
C. 1/4 and 10/48
- 1*48 = 4*10
- 48 = 40, incorrect, not a proportion
D. 1/4 and 9/36
- 1*36 = 4*9
- 36 = 36, correct, this is a proportion
Answer:

Step-by-step explanation:

Multiply both sides by d:

Expand:

+4d on both sides:

Factorise d out of the left-hand side:

Divide both sides by (3x +4):

Answer:
V =192 pi or approximately 602.88 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
We need to determine the radius
r = d/2 = 8/2 =4
V = pi (4)^2 *12
V = pi *16*12
V =192 pi
We can approximate pi by 3.14
V = 192* 3.14
V =602.88 cm^3
The answer is D , Yes they are parallel because the slopes are equal
