Answer:
Option (C)
Step-by-step explanation:
Let the red cases sold = r
and the number of white cases sold = w
Total number of cases sold by the winery = 81
r + w = 81 -------(1)
If number of red cases sold is twice of white cases sold,
r = 2w ------- (2)
By substituting the value of r from equation (2) to equation (1),
2w + w = 81
3w = 81
w = 27 cases
From equation (1),
r + 27 = 81
r = 54 cases
Therefore, number of white cases sold are 27 cases
Option (C) is he answer.
Here we go !!
Since it's a regular pentagon, all it's sides are equal so let's solve for x
now let's find the measure of each side, i.e
perimeter = 5 × side length ( for a regular pentagon )
Answer: c. divide the previous value by 5
Step-by-step explanation:
Answer:
Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.
This means that the value of k will go from 0 to 4, then all the numbers in the sum are:
(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4
So we have 5 terms in our series.
b) to see the sign in each term, we must solve the powers, remember that:
(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:
(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4
= 1 -1/2 + 1/4 - 1/8 + 1/16.
So the sign in each term of the series alternates.
