Answer:
The pencils at store A cost more
Step-by-step explanation:
The complete question in the attached figure
store A
we have
This is a proportional relationship between the total cost (y) and the number of pencils (x)
The constant of proportionality is equal to the slope
The slope or unit rate is equal to
Store B
This is a proportional relationship between the total cost (y) and the number of pencils (x)
The constant of proportionality or slope is equal to
For (6,3.06)
substitute
The linear equation at store B is
<u><em>Verify each statement</em></u>
case 1) The pencils at store A cost more
The statement is true
Because, one pencil at store A cost $0.55 and one pencil at store B cost $0.51
case 2) The pencils at store A cost $0.27 each
The statement is false
Because, one pencil at store A cost $0.55
case 3) The pencils at store B cost $0.30 each
The statement is false
Because, one pencil at store B cost $0.51
case 4) The pencils at store B cost more
The statement is false
Because, pencils at store A cost more
Considering that the square root of 9 is of 81 and of 10 is of 100, we have that the expression that has a value between 9 and 10 is given by:
B.) √89
E.)
F.)
We suppose numbers n and m, with square roots given, respectively, by n² and m².
Then, the square roots of all numbers between n² and m² have values between n and m.
In this problem, the square roots are given by:
- 9² = 81.
- 10² = 100.
Hence, the square root of all values between 82 and 99 are values between 9 and 10, thus option B is correct.
As for the cubic root, we apply the same logic and have that:
- 9³ = 729.
- 10³ = 1000.
Hence options E and F are also correct, as the values between 730 and 999 have cubic roots between 9 and 10.
