The answer is The sum is 10 · 11.

The first 10 positive even numbers are:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20

Their sum is:
2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110

Now, let's present it as two factors:
110 = 11 * 10

Do the following lengths satisfy the Pythagorean Theorem? Lengths =14, 50, 48. Yes No

seraphim [82]

Answer:

yes

Step-by-step explanation:

14² +48² = 196 +2304 = 2500 = 50²

The three lengths (14, 48, 50) are a Pythagorean triple.

Additional comment

The two smaller numbers correspond to side lengths. The larger one corresponds to the hypotenuse length.

We typically write the numbers of a Pythagorean triple in increasing order, but the order doesn't really matter. As sides of a triangle, the triangle formed is a right triangle, regardless of the order.

The price of a cup coffee was 2.40 yesterday. Today, the price fell to 2.15 find the percentage decrease. Round the answer to th

irakobra [83]

ANSWER

The percentage decrease is 10.4%.

EXPLANATION

To calculate percentage decrease, use the formula,

Percentage decrease

$= \frac{new \: price - old \: price}{old \: price} \times 100\%$

Yesterday the price of coffee was 2.40. This is the old price.

Today the price is 2.15. This is the new price.

$= \frac{2.15 - 2.40}{2.40} \times 100\%$

$= \frac{ - 0.25}{2.40} \times 100\%$

$= - 0. 10416667 \times 100\%$

$= - 10.416667\%$

To the nearest tenth, we have:

$- 10.4\%$

Therefore the percentage decrease is 10.4%.
