Answer:

The simplification of the equation is:

16xy+4x+3y+8

Step-by-step explanation:

We need to group similar terms to simplify the algebraic expression:

(15xy+xy)+4x+3y+(21-13)\\16xy+4x+3y+8

Answer:

  x° ≈ 77.6°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between trig functions and triangle sides. Side CD is common to the triangle on the left and the one on the right, so we can consider relationships that might help us use that to find the answer.

In the triangle on the right, we need a relationship between CD and BD. These sides are opposite and adjacent to the given angle, so we can use the relation ...

  Tan = Opposite/Adjacent

  tan(38°) = CD/3.5

Multiplying by 3.5, we can find CD:

  CD = 3.5·tan(38°)

__

In the triangle on the left, we know sides CD and CA, the side opposite x° and the hypotenuse of that right triangle. This lets us use the sine relationship:

  Sin = Opposite/Hypotenuse

  sin(x°) = CD/2.8

__

Using our value for CD, this becomes ...

  sin(x°) = (3.5·tan(38°)/2.8)

  sin(x°) = (5/4)tan(38°)

Using the inverse sine function, we can find x° to be ...

  x° = arcsin(5/4·tan(38°)) ≈ 77.6°

The size of the angle marked x° is about 77.6°.

Darías in 2026 is a pretty great baseball player. Last season,his team won 80% of their games if the team played 35 games last y
natka813 [3]

Answer:

28 games won

Step-by-step explanation:

Total number of games played by the team last year = 35

Percentage of win = 80%

Number of games won can be calculated by finding the win percentage of the  total number of games played and thus can be given as :

⇒ 80\%\ of\ \textrm{Total number of games played}

⇒ \frac{80}{100}\times 35

⇒ \frac{2800}{100}

⇒ 28

∴ Number of games won by the team out of 35 games = 28 games
