Answer:

2√10

Step-by-step explanation:

Draw a vertical line through the corner between the side of length 7 and the side of length 5. This line forms a right triangle with hypotenuse 7 and base (8 - 5), or 3.

The Pythagorean Theorem applies here.

(hypotenuse)² = (base)² + (vertical side)² and this becomes:

7² = 3² + (vertical side)²

Solving this for (vertical side)², we get (vertical side)² = 49 - 9 = 40.

Thus, (vertical side) = √40 = √4·√10 = 2√10 (answer)

Tommy Thomas’s tankard holds 480ml when it is one quarter empty. How much does it hold when it is one quarter full?

agasfer [191]

Answer:

Tommy Thomas's tankard holds 160ml when it is one-quarter full.

Step-by-step explanation:

When Tommy's tankard holds 480ml when it's one-quarter empty. There are three other quarters in the tankard. So, you would divide 480 by 3 to see how much is in each of the other 3 quarters. The answer comes down to 160ml per quarter, which equals one-quarter full.
