Answer:
We conclude that total cost/bill will be: $27.81
Step-by-step explanation:
Given
The cost of an iPhone case = $27
Additional expense = 3% = 3/100 = 0.03
To determine
Total bill = ?
The expense amount can be calculated by multiplying the cost of an iPhone case by the additional expense
i.e.
Expense Amount = cost of an iPhone case × additional expense
= 27 × 0.03
= $0.81
The total cost is calculated by adding the expense amount and the original cost of an iPhone case.
i.e.
Total cost/bill = Expense Amount + cost of an iPhone case
= $0.81 + $27
= $27.81
Therefore, we conclude that total cost/bill will be: $27.81
Answer:
The correct option is B. two oxygen atoms
Step-by-step explanation:
The molecular formula for carbon dioxide is given by :
Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.
And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.
So, The prefix of the first word that is C is 1
⇒ One molecule of carbon dioxide contains one atom of Carbon.
The prefix of the second word that is O is 2
⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.
Therefore, The correct option is B. two oxygen atoms
Answer:
Equation: y = 65x
Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.
Step-by-step explanation:
Pick any two points to find slope, let's got with (3, 195) and (4, 260):
slope m = (y₂- y₁) / (x₂ - x₁)
= (260 - 195) / (4 - 3)
= 65 / 1
m = 65
Find y-intercept by using m from above and another point from your table, let's go with (5, 325):
y = mx + b
325 = 65(5) + b
325 = 325 + b
b = 0
Use m and b to form equation of line:
y = mx + b
y = 65x + 0
y = 65x
Check:
point (3, 195): 195 = 65(3) ====> 195 = 195
point (4, 260): 260 = 65(4) ====> 260 = 260
point (5, 325): 325 = 65(5) ====> 325 = 325
point (6, 390): 390 = 65(6) ====> 390 = 390
Example of a point that doesn't belong on table:
point (8, 500): 500 = 65(8) ====> 500 ≠ 520
Answer:
80
Step-by-step explanation:
The value of x must be greater than 77
The only number greater than 77 is 80
