Answer:
40 cm^2.
Step-by-step explanation:
Area = the sum of the 2 triangles
= 1/2 * 6 * 8 + 1/2 * 4 * 8
= 24 + 16
= 40 cm^2.
Answer:
6 spaces to the right 3 spaces up
Step-by-step explanation:
I don't know if this will help you any but for plotting points I was always taught to go to the tree before you climb. meaning you go on the x axis for the first number then on the y axis for the second number. Hope this can help you in the future!
Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15. Filling in accordingly, we have

. Simplifying a bit gives us

and

. Raising that number inside the parenthesis to the 15th power gives us

. Multiplying to finish means that A(t) = $317.22
We will need to find the area of the circle. We will use this formula:
A =

* radius^2
The question says we will use 3.14 for

.
And we know radius is equal to 22.
A = 3.14 * 22^2
A = 3.14 * 484
A = 1519.76
Round to the nearest tenth.
A = 1519.8
So, the maximum area the sprinkler can water is <span>1519.8</span> ft squared.
EDIT:
I found a mistake in my answer.
Answer:
There are 7^20 possibilities fir the people to get off the elevator
Step-by-step explanation:
I am going to assume that some people (but not neccesarily all) get into the elevator in the low level and none at the highest. Since we are looking for the possibilities for the people to get off the elevator, we can assume that everyone get into in the low level, because this case will contain every possible scenario. Each person has 7 possible ways to get off, hence 20 person will have 7 possibilities powered 20 times, hence there are 7^20 possibilities fir the people to get off the elevator.
