Series would be: 1,3,5......99
Here, a=1, d = 3-1 = 2, l = 99
l = a+(n-1)d
99 = 1+(n-1)2
98 = 2n-2
2n = 100
n = 50
Sum would be Sn = n/2 (a+l)
50/2 (1+99)
25(100) = 2500
So, your answer is 2500
Answer:
270
Step-by-step explanation:

7x6 to get part of the other shape
21 -6-7 to get the triangle that we don't have a number
8x6 to get a square but then divide by 2 too get the triangle.
now add all together to get 102
Answer:
c = sqroot45
Put a 45 in the box under the square root.

Let
x: represent the number of males on the ride
y: represent the number of females on the ride
We have the following system of equations:
x+y=36
x/y=5/4
rewritting:
y=(4/5)x
answer:
a system that you can use to find the number of males and the number of females on the ride is:
y=(4/5)x
x+y=36
