Answer:

You need to use Pythagorean's Theorem.

Step-by-step explanation:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

a^2 + b^2 = c^2.

Tems11 [23]

Answer:

75

Step-by-step explanation:

Since the ratio between flamingos and chachalacas is 2:1, we see that the ratio of flamingos to chachalacas to parrots to herons is 10:5:7:3. The sum of these numbers is 25, so every 'ratio number' gets 375/25 = 15 animals. So the number of chachalacas is 15 * 5 = 75.

A store owner bought a painting for $120. She is selling it for $190. What is the percent markup on the painting
stiks02 [169]

Answer:

The markup percent on the painting is 58.3%

Step-by-step explanation:

Here, The Cost price of the painting = $120

The selling price of the painting = $190

Hence, the total profit on the painting = Cost Price - Selling price

or Profit =  $190  - $120 = $70

Now, Markup % =  (Gross Profit / cost)  x 100

⇒Markup % = \frac{70}{120}  \times 100 = 58.3

Hence, the markup percent on the painting is 58.3%
