Answer: 1: 3x
2: area
3: six
4: 3/2
Step-by-step explanation:
Use the algorithm method. Then multiply. The answer should be 135.
If you don't know what algorithm is, it's when you put a number over a number. And multiply it.
Using the powers of 9, it is found that the last digit of the product will always be either 1 or 9.
--------------------------------
The multiplication of as many 9's as you want is equivalent to the powers of 9, which are:
....
Thus, the last digit of the products will always be either 1 or 9.

Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is th of the total time.
Hence, option D is correct.
Answer:
The second choice. One-third of the product of the height and base area
Step-by-step explanation:
The formula for volume of a pyramid is
V = (1/3)Bh, where V is the volume, B is the area of the base, and h is the height.
Translated to English the formula says
"Volume is one-third the product of the base area and the height"
