a / 75 = 15 / 100
100a = 75 * 15 [cross multiplication]
a = 11.25
i hope this helps!!! :D
Cost of fuel = 30% of $400 000 = 30/100 x 400000 = $120 000
Fuel amount = $120 000/$1.5 = 80 000 liters
new cost of fuel = 80000 x $1.6 = $144 000
increase in cost = 144000 - 120000 = $24000
So the increase in petrol price increases the operating cost by $24000
If you understand trigonometry, this should be easy :)
First we should change these mixed numbers into improper fractions:


We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:

/

*

So now we know that
Otto used 7 crates.
Answer:
Otherwise, if you're using definition A, the most a trapezoid could have is two right angles, and therefore, two perpendicular sides.
