I can only assume it would be 18 gallons. 140/14= 10 miles per gallon. 180 miles=180/10. Hope this helps
For 9, do 0.5*6*9.2*5 to get the total area of the visual triangles, add that to 0.5*6*4.1*5 to get the area of the pentagon and you should get 199.5 cm^2for 10, do 0.5*6.9*8*12 to get the total area of the figure and you should get 331.2 cm^2
The quantity remaining will be
.. 448*(1/2)^(24/6) = 448/16 = 28 . . . . grams
Lets get started :)
This is an example of a simple interest
The formula to calculate simple interest is:
I = prt ( In the picture attached you can see what each stands for )
Given are initial amount → $600
interest anually → 1.7%
time → 10 years
Let us convert the interest percentage into decimals

I = ( 600 )( 0.017 )( 10 )
= $102
We need to add this amount to the initial to find what is left over a time period of 10 years
$600 + $102 = $702
$702 will be left in your account
