Answer with Step-by-step explanation:

We are given 2 terms

20w and 40wz

We have to find their common factors.

20w=2×2×5×w

40wz=2×2×2×5×w×z

As we can see from the above factorization that,

10=2×5 is common in both

20w=2×2×5×w is common in both

2w=2×w is common in both

w is common in both

Hence, the common factors of 20w and 40wz are:

10,20w,2w and w

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing
Zigmanuir [339]
So first we add up all the marbles. Which would be 25. Then we look to see how many red marbles there are. There are 5. You have a 5/25 chance of drawing a red marble. But you can reduce that. So when it's all said and done you have 1/5 chance of drawing a red marble.
Hope this helps!

Find the 64th term of the arithmetic sequence
Margaret [11]

Answer:

The 64th term of the arithmetic sequence is -1075.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same.

The nth term of an arithmetic sequence is given by:

a_n = a_1 + (n-1)d

In which a_1 is the first term.

−4,−21,−38

First term -4, so a_1 = -4

Common difference of d = -38 - (-21) = -21 - (-4) = -17

Thus

a_n = a_1 + (n-1)d

a_n = -4 - 17(n-1)

Find the 64th term of the arithmetic sequence

This is a_{64}. So

a_n = -4 - 17(n-1)

a_{64} = -4 - 17(64-1) = -4 - 1071 = -1075

The 64th term of the arithmetic sequence is -1075.
