Step-by-step explanation:
Because the y-coordinate stays the same, only look at the x-axis. Subtract 17.1 - 21.4 to get your length
Answer:
i believe it only has one solution, which would be x=12.
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
No repetition.
There are a total of 7 numbers.
For the number to be even it must end in 0, 2 or 8.
The other 3 numbers will be the number of permutations of 3 from the 6 other numbers.
Number of 4 digit numbers ending in 0
= 6P3 = 6! / 6-3!
= 120.
Now the number could also end in 2 or 8,
so there are 3*120 = 360 4-digit even numbers (no repetition).
With repetition.
There are 3 * 7^3 = 1029 with repetition.
First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.
72/3 = 24
We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.
To solve this problem subtract 20 from one third of the number 72; 24.
24 - 20 = 4
The number that Barbie is thinking of is 4.
