Answer:
Step-by-step explanation:
Use the formula Sum = (a + L)*n/2
The tricky part is n. That's the number of terms between 1 and 99 inclusive.
n = 99 -1 + 1 = 99
n = 99
a = 1
L = 99
Sum = (1 + 99)*99 / 2
Sum = (100)*99/2
Sum = 4950
8/11 of what = 16
8/11x = 16
x = 16 * 11/8
x = 176/8
x = 22......so there are a total of 22 fish in the tank
Answer:
Circunferencie can be writen also as a fuction of the diameter of the circle
C = pi*D
Where
D = circunferene diameter
Step-by-step explanation:
C = 2.pi.R = 2.R.pi
In a circle 2.R = D
So,
C = pi.D
Bc there ia a 60% chance of winning so the chance of not winning is 100%-60%= 40%.
Answer:
-11
Step-by-step explanation:
Plug in -2 for x
5(-2) - 1
Order of operations (or PEMDAS) tells you to multiply first giving you:
-10 - 1
-10 - 1 = -11
