Answer:
see below
Step-by-step explanation:
The sum of an infinite series with first term "a" and common ratio "r" is ...
S = a/(1 -r) . . . . . for |r| < 1
Then the sums for the given answer choices are ...
A: 5/(1 -3/4) = 20 . . . . . the answer of choice
B: 4/(1 -5/6) = 24
C: 4/(1 -1/5) = 5
D: 10/(1 -1/5) = 12.5
Answer:
Value of the given expression will be 19.
Step-by-step explanation:
We have to find the value of the given expression for a = 3, b = 5 and c = 12
Expression → |a + 1| + |b - c| - |-8|
We will use the property of absolute value,
|+a| = a
|-a| = a
By substituting the values of a, b and c in the given expression,
|a + 1| + |b - c| - |-8| = |3 + 1| + |5 - 12| - |-8|
= |4| + |-7| - |-8|
= 4 + 7 + 8
= 19
Therefore, value of the given expression will be 19.
Answer: C
The equation (b + 4r = 7) is a missing number equation, not representing log10. The equation (p- (7q + 1/2 r) would be correct, if the 7q were a 2q. The answer to the question would have to be C, (x / y^2 √z).

Given:
Granny Apples charge $12 for 6 pounds of apples.
Wilson' Apples charges $15 for 5 pounds of apples.
To find:
Which apple company provides a better deal.
Solution:
We need to compare unit price of both companies.
![\text{Unit price}=\dfrac{\text{Total price}}{\text{Number of units}}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20price%7D%3D%5Cdfrac%7B%5Ctext%7BTotal%20price%7D%7D%7B%5Ctext%7BNumber%20of%20units%7D%7D)
Unit price of Granny Apples,
![\text{Unit price}=\dfrac{\$12}{6}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20price%7D%3D%5Cdfrac%7B%5C%2412%7D%7B6%7D)
![\text{Unit price}=\$2](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20price%7D%3D%5C%242)
Unit price of Wilson Apples,
![\text{Unit price}=\dfrac{\$15}{5}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20price%7D%3D%5Cdfrac%7B%5C%2415%7D%7B5%7D)
![\text{Unit price}=\$3](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20price%7D%3D%5C%243)
Since, per unit price of Granny Apples is less than Wilson Apples, therefore Granny Apples provides a better deal.
