Lets begin with an example.
You have 100 apples. 40 % of your apples are 40. Sounds complicated?
Here is the calculation in words, number of apples times 40 percentage.
By equation: 100 * 40/100= 40. Simple huh?
% symbol represents 100.
% 15 equals 15/100; 20% is equal to 20/100 or 1/5 in a simplified way.
Have a look to question. 40 iris at last year, 15 % MORE iris this year.
What is the 15 % of 40 iris? That's the question at the end.
Recall apple example at the beginning.
40 iris * 15/100 = 6.
So, there are 6 MORE iris blooms this year. This year Savanna has totally 46 iris.

1=1=1=1=1=1=1=1=1=1=1=1=1=1=1
Step-by-step explanation:
First, find the expected number of scooters rented per month:
As the data is symmetrical, E(X) (the expected value) is the middle value. So, on average, 2.5 scooters should be taken per month.
His total costs were 5 * 3000 = $15,000
So, to break even, he needs to make $15,000.
He will be selling for 5 years, or 60 months.
As a result, he needs to make 15000/60 = $250/month
As he is selling 2.5 scooters on average, he needs to rent each for:
$250/2.5 = <u>$100/month</u>
Answer:
x=-3
Step-by-step explanation:
Hi there!
<u>1) Determine the slope</u>
Parallel lines always have the same slope. However, the given line x=8 is a vertical line organized in the form x=d, where d is the x-intercept. Therefore, the slope is undefined, and our line will also have an undefined slope.
Now, because this line will also be a vertical line, it will also be organized like:
x=d
<u>2) Determine the x-intercept (d)</u>
Note that all the points a vertical line passes through will have the same x-coordinate. We're given that this line passes through the point (-3,-2), so therefore, the x-intercept will be (-3,0).
Plug this into x=d:
x=-3
I hope this helps!
Answer:
Step-by-step explanation:
To solve this, we will have to use multiple methods, including the pythagorean theorem and the 30 60 90 rule.
In the 30 60 90 rule, it is stated that the angle opposing the side with 30 degrees is represented by 
, the angle opposing the side with 60 is 
and the angle opposing 90 degree angle is represented by 
. Looking at the whole triangle, we can see the 30, 60 and 90 degrees, and the angle with 90 has an opposing side of 15, which means we have to use 15=2s to find the other sides. When dividing 15 by 2, you get 7.5, which is s. Now we know that the angle opposing 30 is 15/2, which is x. Now that we have "s", we can also solve for z, represented by the 60 degrees. Multiply 7.5 and 
to get z=35113/2703.
Now we can solve for the smaller triangles. Since we have already found x, we can use the 30 60 90 method in this too. The x (15/2) is now represented by 2s. Therefore, solve for your new s by doing this: 15/2 = 2s. You should get your 30 degree angle answer (a) with this, which is 15/4. Now that we have to use pythagorean theorem, which is 
to solve for the remaining side (y) of the small triangle. You should get 35113/5406.
Finally we have the last side left: b. Since we have so many sides now, all we have to use is the pythagorean theorem again. Use 
and solve for b. You should get 45/4.
