The greatest common factor (GCF) of 49 and 63 is: 7
To find the GCF, you simply gather up the factors for both of the numbers, but make sure you only write out the factors that are less or equal to 49, since you shouldn't go over the minimum number.
Factors of 49: 1, 7, 49
Factors of 63: 1, 3, 7, 9, 21
Now that we know the factors of both of the numbers, we should find the most common between them. Which numbers are common between the two numbers? The common factors of them are 1 and 7, but we are looking for the greatest common factor. Now, which is the greatest of 1 and 7? It is 7, since 7 is a higher number than 1.
Answer:
y ≠ - 9
Step-by-step explanation:
the denominator of the expression cannot equal zero as this would make the expression undefined. Equating the denominator to zero and solving gives the value that y cannot be
solve y + 9 = 0 ⇒ y = - 9 ← not permissable
Answer: 615.4mm cube
Step-by-step explanation:
The volume of a cylinder is given as πr^2h
where r= radius
h = height
π = 3.14
From the question, diameter is 14mm and height is 4mm.
To get the radius, we divide the diameter by 2 which will give:
= 14mm/2 = 7mm
Volume= πr^2h
= 3.14 × 7^2 × 4
= 3.14 × 49 × 4
= 615.4mm cube
The volume of the cylindrical barrel is 615.4mm cube.
