1. Tiffany bought a phone for $350. If the value of the phone depreciates at a rate of 6%
Misha Larkins [42]

Answer:

Amount of phone after 3 year = $290.7 (Approx.)

Step-by-step explanation:

Given:

Amount of phone = $350

Depreciation rate = 6% = 0.06

Find:

Amount of phone after 3 year

Computation:

A = p[1-r]ⁿ

Amount of phone after 3 year = Amount of phone[1-Depreciation rate]ⁿ

Amount of phone after 3 year = 350[1-0.06]³

Amount of phone after 3 year = 350[0.94]³

Amount of phone after 3 year = 350[0.83054]

Amount of phone after 3 year = $290.7 (Approx.)

If a trench is 102’-6” long by 5’-4” wide and 3’-3” deep, what is the volume of the soil that was removed per cubic feet?
zzz [600]

Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.

The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

V = lwh

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:

  • The length is of 102' 6''(102 feet and 6 inches), hence l = 102.5.
  • The width is of 5' 4'', hence w = 5.33.
  • The depth(height) is of 3' 3'', hence h = 3.25.

Then:

V = lwh = 102.5(5.33)(3.25) = 1776

The volume that was removed is 1776 cubic feet.

Choose either the SSS Postulate or the SAS Postulate and explain in your own words how you use that postulate to prove two trian
Veronika [31]
Let's use the SAS postulate! SAS means Side, Angle, Side. I would sometimes write this the other way and get in trouble, haha. 
It technically means if a triangle that has a congruent angle between two congruent sides, it means it is congruent. Here is a picture.

For a weekly car rental, a car rental company charges customers a flat fee of $100 plus
zlopas [31]

The way you typed out this sentence was a bit confusing but I think you were saying...

For a weekly car rental, a car rental company charges customers a flat fee of $100 +  and charges 10 cents for every mile traveled. write an equation for the amount of a weekly rental car that travels 15 miles (Please let me know if I am wrong)

The equation would be

10+10 +10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10 = 150 cents

so they would be charging $1.50

Hoped this helped!

Have a great day/night! :)
