Answer:
out of the entire piece 160/200 is shaded, after simplifying it should be 4/5
Step-by-step explanation:
count the total, in this case 200 blocks
then count the shaded area, 160
160/200 --> after simplifying --> 4/5
Answer:
D
Step-by-step explanation:
7^[2^(x/25)]
7^{[2^(1/25)]}^x
7(1.028113827^x)
Since 1.028113827 is greater than 1, it's an increase
And x is in minutes, so the increase is per minute
Answer:
x = 3

Answer: For Part A, there are 9,604 possibilities. For Part B, there are 1,440 possibilities.
To find the total number of possibilities, we will use the Fundamental Counting Principle. To do this, we find the number of possibilities for each position and then multiply them.
For Part B:
There are only 4 possibilities for the first position, since it must be odd (1, 3, 5, 7). The for the next 4 digits, all 7 numbers are a possibility.
4 x 7 x 7 x 7 x 7 = 9604
For Part B:
We again start with 4, however the numbers can be repeated. So we reduced the number of choice by 1 each time.
4 x 6 x 5 x 4 x 3 = 1440
