If the ratio of star shaped cookies to circular cookies is 5: 6 and the ratio of circular cookies to triangular cookies is 3: 10
SCORPION-xisa [38]

Answer:

1:4

Step-by-step explanation:

Without loss of generality, let there be 5 star shaped cookies. Following the proportions given, there will be 6 circular cookies. We can set up the following proportion to find out how many triangular cookies there would be:

\frac{3}{10}=\frac{6}{x},\\3x=60,\\x=20.

Therefore, for every 5 star shaped cookies there will be 20 triangular cookies.

Simplifying this ratio we have 5:20 \implies \boxed{1:4}.

Anton defines an acute angle as an angle that is not obtuse. Is Anton's definition valid ?
kobusy [5.1K]

Answer:

Anton's definition is not valid.

Step-by-step explanation:

We have been given that Anton defines an acute angle as an angle that is not obtuse. We are asked to find whether Anton's definition is valid or not.

We know that an angle is known as acute angle whose measure is greater than 0 and less than 90 degrees.

We also know that an angle is known as obtuse angle whose measure is greater than 90 degrees and less than 180 degrees.

We know that a right triangle is neither acute nor obtuse. Since Anton hasn't mentioned a right triangle to his definition, therefore, his definition is not valid.
