Answer:
$59.27
Step-by-step explanation:
It is exponential decrease.
After each year goes by its worth 100 - 0.13 = 0.87 of the previous value.
The equation of decrease is V = 90(0.87)^t where t = the number of years.
So after 3 years it is worth 90(0.87)^3
= $59.27.
The length of edge FC in the triangular prism is: 12 cm.
<h3>What is the Volume of a Right Triangular Prism?</h3>
Volume of a right triangular prism = 1/2(Length of triangular base × height of triangular base × height of the prism).
Considering the image given showing a right triangular prism, we have the following:
Volume of triangular prism = 900 cubic centimeters
Length of triangular base = FC = ?
Height of triangular base = 10 centimeters
Height of the prism = 15 centimeters
Plugin the values
900 = 1/2(FC × 10 × 15)
900 = 1/2(FC × 150)
Multiply both sides by 2
2(900) = 2(1/2(FC × 150))
1,800 = FC × 150
Divide both sides by 150
1,800/150 = FC × 150/150
12 = FC
FC = 12 cm
The length of edge FC is: 12 cm.

Answer:
it is the first one
Step-by-step explanation:
The best thing to do is to divide 1440 by 240, which will allow you to find a unit rate (which will be the length of time that the journey takes)
1440/240= 6.
Therefore, the journey takes 6 hours
Hope this helps :)
$7.50•2= $15.00
15.00+$15.50= $30.50 in total good luck :)))
