The sum of the arithmetic series has a formula of
S = (n/2)(a₁ + aₙ)
where
n = number of terms
a₁ = first term
aₙ = last term or nth term
Given n = 50, a₁ = -13, aₙ = 134. The sum is
S = (50/2)(-13 + 134)
S = 3025 (ANSWER)
Answer:
no
Step-by-step explanation:
you will not incur a delivery charge because you live in the 25 mile radius, because your house is within the radius, so you wouldn't incur the delivery charge. when they say a 25 mile radius, that means in every direction.

Divide 18,472 by 5,280.
18,472 / 5,280 = 3.5
18,472 feet is about 3.5 miles.
Answer:
The first choice (m<1=m<2=72)
Step-by-step explanation:
Since <ABC is bisected by BD, it's split evenly in half. Divide 144 by 2 and you get 72
