Phillip received 75 points on a project for school. He can make changes and receive two-tenths of the missing points back. He ca
1 answer:
The geometric sequence of the missing points is:
a is the missing points initially. Assuming 100 marks, this is 25
r = 8/10, as the missing marks reduces by 2/10 each time
Assuming the marks are out of 100, and marks are rounded to the nearest whole number, the maximum mark he can get is 98, as 2/10 of the remaining 2 marks would make it 98.4, which would round back to 98.
This series is converging, as the 8/10 gets smaller every time, so the series will eventually converge.
Hope this helps :)

Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Amount Josh earn each summer = $2700
Rate of simple interest = 4.5%
According to question, he deposits the same amount each year.
First summer, he deposited = $2700
In Second summer, he deposited = $2700×2= $5400
In Third summer, he deposited = $2700 × 3=$8100
At the end of his third summer, his money becomes,
As we know the formula for "Amount" that it becomes at the end of his third summer:
Hence, Option 'B' is correct.
Answer:
415.8 meters
Step-by-step explanation:
We know the adjacent and the opposite, so we will use tan
tan 22 = opp/ adj
tan 22 = 168/x
x tan 22 = 168
x = 168/tan 22
x =415.81459
Rounding to the nearest tenth
415.8 meters
To use the equal values method, we want to get both of these equations equal to the same thing, and then set them equal to each other. To do this, let's solve both for x:
For the second equation:
Then if we set these two equal to each other:
Then we take this y value and plug it back into either of our starting equations. I'll use the first one as an example:
Now just solve for x and you'll have your solution.
