Answer:

The angles in a triangle should always add up to 180 degrees.

The four angles made by a set of intersecting lines will always add up to 360 degrees and the ones across from eachother are always the same.

This means that the triangle's unmarked angle is 60 degrees.

2*24 = 48 and 3*24 = 72 48 + 72 + 60 = 180 degrees

24 will be your correct answer.

Mrs. Benson has 184 math assignments left to grade.

Step-by-step explanation:

Here we have , Mrs. Benson has graded 46 math assignments but has 80% of the assignments left to grade.We need to find Mrs. Benson has how many math assignments left to grade. Let's find out:

Let total Number of math assignments be x , So According to question 46 math assignments are graded & 80% are left i.e.

⇒ $x = 46+\frac{80x}{100}$

⇒ $x -\frac{80x}{100}= 46$

⇒ $\frac{100x-80x}{100}= 46$

⇒ $\frac{20x}{100}= 46$

⇒ $\frac{x}{5}= 46$

⇒ $x=230$

Now , Assignments left to grade is :

⇒ $230-46$

⇒ $184$

Therefore , Mrs. Benson has 184 math assignments left to grade.

worty [1.4K]

Answer:

The ratio of African Americans to Hispanics Americans present is 16 : 5

Explanation:

Given the people attending the soccer game were:

2800 among them are Caucasians

4800 are African Americans

1500 are Hispanics

And, 1400 of those were from other ethnic backgrounds

We have to find the Ratio of African Americans to Hispanics Americans

Therefore,

African Americans : Hispanics Americans = 4800 : 1500

$\frac{\text { African American }}{\text { Hispanics American }}=\frac{4800}{1500}=\frac{48}{15}=\frac{16}{5}$

Hence, the ratio of African Americans to Hispanics Americans present in the ratio were 16 : 5
