For this case we have that by definition, the GCF of two numbers is the biggest common factor that divides both numbers without leaving residue. We find the factors:
26: 1,2,13,26
78: 1,2,3,6,13,26
Thus, the GCF of both numbers is 26
Answer:
26
Option C
Answer:
10:40
Step-by-step explanation:
As the left number increases by 1, the right number increases by 4. So as you can see, the left numbers go 3-4-5 while the right numbers go 12-16-20. So the answer is 10:40 because 10x4=40.
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9
Answer: 13 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the height*width*length.
3 1/4 as a decimal is 3.25.
Now we can plug in the given values into the formula for the volume.
Therefore, the volume = 3.25 cm * 4 cm * 1 cm
= 13 cm^3
