The answer is b because the ratio is blondes to brunettes.
Here's the relevant formula:
1 - r^n
nth partial sum = a* ------------
1 - r
1 - r^25
Here, the 25th partial sum is 177147 *-------------
1 - r
Unfortunately, you haven't yet shared the value of the common ratio. Find that value and substitute it for r in the above expression.
If there are 10 wild cards there are 50 standard cards. 8 and 40 can both be divide by 4, which makes 2/10. This means that there are 2 wild cards for every 10 standard cards. If there are 50 wild cards, you simply multiply 2/10 by 5. This will give you 10/50. 10 wild cards in 50 standard cards.
Answer:
1. 2x² - 8x - 7
2. x³+ x + 30
Step-by-step explanation:
<h3>Possible coordinates of R = -5 or 5</h3><h3>Possible coordinates of T = -7 or 7</h3>
==================================================
Explanation:
If we're on a number line, then R could be at either R = 5 or R = -5. This is so the distance from A to R is 5 units. Distance is never negative. You count out the spaces to get the distance, or use subtraction and absolute value.
Saying "distance from A to R is 5" can be written as AR = 5. Meaning segment AR is 5 units long.
Now if AT = 7, then T could be at 7 or -7 on the number line. The reasoning as similar as to why R could be at -5 or 5.
