Answer:
Yes,
There is a direct proportional relationship between the cost of items before tax and the cost of items after tax.
Step-by-step explanation:
Given - A city has a 5% sales tax.
To find - Is there a proportional relationship between the cost of items
before tax and the cost of items after tax?
Proof -
Yes, cost of items before tax is directly proportional to cost of items after tax.

With the increase in the sales tax, there is increase in the cost of items after tax, therefore, there is a direct relation between cost of items before tax and cost of items after tax.
Answer: P =38.7 in, A=63.7in^2
Step-by-step explanation: start by using the formula for area of a triangle: A =bh/2 and plug in values given for the larger triangle to find the height. 115=9h/2,. 230 =9h h= 25.556
Subtract from perimeter to get an estimate of the third side: 62-34.556=27.45
Realize now that the drawing is not to scale!
Use the dimensions of the larger triangle to and the proportion 6.7/9 = smaller / larger to find other dimensions of the smaller triangle. Add the sides to get perimeter. Multiply bh/2 to get the Area. Choose the answer that is closest to your calculations as the numbers are estimated. We cannot assume that this is a right triangle.
