Answer:
Step-by-step explanation:
The long division for 3/8 results in getting 0.375, so 45 3/8 is 45.375.
From here, the only thing you can really do is divide it by 10 to get
4.5375 and since you can't divide further, the answer would be
4.5375 * 10^1
Answer:
a. 25
Step-by-step explanation:
Sₙ = n/2 * (2 * a₁ + (n-1) * d)
Sₙ = 500 a₁ = -4 d = 2
500 = n/2 * (-8 + (n-1) * 2) = n/2 * (-8 + 2n - 2) = n/2 * (2n - 10) = n² -5n
n² - 5n -500 = 0
(n - 25) (n + 20) = 0
n > 0
n = 25
C. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)
