Answer:
24 terms
Step-by-step explanation:
The sum of an arithmetic sequence is the average of the first and last terms, multiplied by the number of terms. The last term is given by ...
an = a1 + (n-1)d
We have a sequence with first term a1 = 2 and common difference d = 2. So the last term is ...
an = 2+ 2(n -1) = 2n
Then the average of first and last terms times the number of terms is ...
Sn = 600 = n(2 + 2n)/2 = n(n+1) . . . . . . close to n²
We can solve the quadratic in n, or we can estimate the value of n as the integer just below the square root of 600.
√600 ≈ 24.5
so we believe n = 24.

S24 = 24·25 = 600 . . . . . . as required.
Step 1 (simplify):
3+5x(2-1)
8 x 1
Step 2 (solve):
8 x 1 = 8
8 is your answer. Hope this helps :)

Hello!
To find our scale factor, let's divide our real length (1,500) by our scale length (7.5)
1,500/7.5=200
Now, we divide our tennis court dimensions by 200.
120/200=0.6
60/200=0.3
Therefore, our answers are below.
Length: 0.6 feet
Width: 0.3 feet
I hope this helps!
