in chess, Justin won 20 games, tied 8 games, and lost 14 games last year. What is Justin’s ratio of total games to tied games

zhuklara [117]

Problem: In chess, Justin won 20 games, tied 8 games, and lost 14 games last year. What is Justin’s ratio of total games to tied gamesSolutions:=> There are a total of 20 games=> 8 of them were tied=> 14 games were lost.Now, let's find the ratio of the tied games to the total games.=> Since the total game is 20 and the tied games are 8, therefore the ratio will be:<span>=> 8 : 20, where 8 are the tied games and 20 is the total</span>

Find the value of x in the isoscleles triangle sqrt45 and altitude 3

Alisiya [41]

Answer:

$c.\hspace{3}x=12$

Step-by-step explanation:

Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.

You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

$x=2a$

And we can find a easily using pythagorean theorem:

$(\sqrt{45} )^{2} =3^{2} +a^{2}$

Solving for a:

$a^{2} =(\sqrt{45} )^{2} -3^{2} \\\\a^{2} =45-9\\\\$

$a^{2} =36\\\\a=\sqrt{36} \\\\a=6$

Therefore:

$x=2a\\\\x=2(6)\\\\x=12$

Logarithmic and Exponential Forms of Equations In Exercise, write the logarithmic equation as an exponential equation, or vice v

Nata [24]

Answer:

$12 = e^{2.4849}$

Step-by-step explanation:

For this case we have the following expression:

$ln(12) = 2.4849$

We need to remember that the natural log and the exponentiation with the base the euler number e are inverse operations, and if we apply exponentiation on both sides of the equation we got this:

$e^{ln(12)} = e^{2.4849}$

We have the identity operator for this $e^{ln(x)}= x$

$12 = e^{2.4849}$

And that would be our final answer for this case.
