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: Aiden bought 8 notebooks and 5 covers.
This is a system of equations problem. To solve this, we have to write 2 different equations and then solve them.
Our equations are:
x + y = 13
1.37x + 1.08y = 16.36
Where x is the number of notebooks and y is the number of covers.
To solve these equations, you can use anyone of these methods:
1) Graphing
2) Substitution
3) Elimination
The easiest way would be to graph them with a graphing calculator and find the point of intersection.
The cost of plating a rectangular jewelry box is $125, the cost of plating a similar box that is 8 times the size will be given by:
Cost=(scale factor)*(price)
Cost=125×8
Cost=$1000
Answer:$1000
Shaded is 8.67
Circle A= pir^2
A= 3.14(4)(4)
A= 50.24
Hexagon
A= 1/2ap
1/2(4)(2sqrtof3)(6)
A= 41.569
50.24-41.569=8.671
The point-slope form of the equation of the line through the given points through: (-3,-1) and (-2,5) is y + 1 = 6x + 18
<u>Solution:</u>
Given, two points are (-3, -1) and (-2, 5)
We have to find that a line that passes through the given two points.
First let us find the slope of the line that passes through given two points.
<em><u>The slope of line "m" is given as:</u></em>
Now, let us find the line equation using point slope form
where m is slope
Hence the point slope form is y + 1 = 6x + 18
