Answer: 14,000 i think
Step-by-step explanation:
<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17
To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.
Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)
Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17
Again, the dimensions should be a square. 17 X 17.</span>
Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
Answer:
Step-by-step explanation:
245000 last year
This year 25235
(y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
(( £25.235 - £24.500) / £24.500) * 100 = 0 %
There ain't no percentage change as there needs to be a bigger difference between the two numbers plus u should use the formula
Answer:
200 dollars,
I am assuming that your question goes like this: "Kiersten runs a website that helps people learn programming. Every month, Kiersten reveives a subscription fee of $10, $10 from each of the subscribers to her website. Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription. How much money will Kiersten's online business earn this month?
Step-by-step explanation:
Since her website had 100 subscribers last month, she earned $1000 (100 x 10). This month, 30 members joined and 10 members left, so in total, she gained 20 subscribers for a total of 120 subscribers this month. So she made 1200 dollars this month (100 x 120). She earned 200 more dollars this month since 1200-1000=20.
