You drive 75 miles and use 3 gallons of gas, at the same ratio, how may miles can you drive with 12 gallons of gas?
umka2103 [35]

When you say "at the same ratio", you mean that you consume the same amount of gas for the same amount of miles.

We know that everytime you drive 75 miles, you use 3 gallons of gas.

Since 12 gallons of gas is four times 3 gallons of gas, if the ratio remains the same, you can drive four times the distance:

You drive 75 miles, and use 3 gallons.

You drive 75 more miles (so you are at 75+75 = 150 miles) and use 3 more gallons, so you use 3+3 = 6 gallons.

You drive 75 more miles (so you are at 150+75 = 225 miles) and use 3 more gallons, so you use 6+3 = 9 gallons.

You drive 75 more miles (so you are at 225+75 = 300 miles) and use 3 more gallons, so you use 9+3 = 12 gallons, and you're done.

The figures are similar. Find the missing length.
saw5 [17]

Step-by-step explanation:

<h2>Answer:-</h2><h3>Given ,</h3>

The figure is Similar.

Observation:-

Similar figures have similar sides. If we see carefully in smaller triangle, 3 has been added to each side and they are similar. We need to find y.

We have :-

5+3=8 as similar sides.

So, applying same algorithm,

y + 3 = 5

y = 5 - 3

\boxed{ \tt{y = 2 \ cm}}

is the answer.

Hope it helps :)
