The opening soccer game at the new arena was attended by approximately 2,800 Caucasians, 4,800 African Americans, and 15,00 Hisp

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

Answer:

$f(x)g(x) = (3 - i)(4i) \\ = 12i - 4 {i}^{2} \\ = \boxed{12i + 4 }\\ remember \:the \: value \: of \: {i}\: is \: \sqrt{ - 1} \\ and \: {i}^{2} \: is - 1 \\ d. (4 + 12i)\: is \: the \: right \: answer.$

If 12 bags of plaster covers 54m²,then how many bags would I take to cover 36m² ???

Zinaida [17]

Well, let's first find our rate of bags to meters.
If 12 bags of plaster covers 54m^2, then we need to divide 54 by 12 to figure out how many meters 1 bag of plaster covers. We will then use that rate and divide 36 by it in order to solve for how many bags of plaster is required.

54 / 12 = 4.5.
This means each bag of plaster covers 4.5m^2.

Divide 36 by 4.5;
36 / 4.5 = 8.
This means that we will need 8 bags of plaster to cover 36m^2.

I hope this helps!
