Answer:
146%
Step-by-step explanation:
To find the percent increase/decrease:
1. Subtract the original value from the new value.
2. Divide by the original value.
3. Multiply the decimal by 100 to convert to a percent.
98.9 - 40.2 = 58.7
58.7/40.2 = 1.46
1.46*100 = 146%
So take 48 then subtract 31 which would equal 17. Then add back the yards they lost. So 17+19=36
By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is 
<h3>What is
sequence ?</h3>
Sequence is collection of numbers with some pattern .
Given sequence
We can see that
and
Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2
Now 
term of this Geometric progression can be written as
So summation of 15 terms can be written as

Answer:
0.1
Step-by-step explanation:
The <em>common ratio</em> of a sequence is the number you multiply one term to get the next one. Here, we multiply 0.1 by 0.1 to get 0.01, and 0.01 by 0.1 to get 0.001, so our common ratio is 0.1.
Answer: The Answer is B
Step-by-step explanation:
You need to distribute 15x(10x - 4). 15x times 10x is 150x and since there is 2 x's your gonna square it. So then it would be 150x². next 15x times -4 is -60 and add your x. Your answer is 150x² - 60x.
