Combined, there are Asians, Africans, Europeans, and Americans in a village. The number of Asians exceeds the number of Afric

yanalaym [24]

There are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

To determine the number of Asians, Africans, Europeans, and Americans in the village, the following calculation must be performed:

A.S + A.F + E.U + A.M = 177
A.S = A.F + E.U + 69
E.U - A.M = 13
E.U = A.M + 13
2A.F = E.U + A.M + 29
A.F + E.U + 69 + A.F + E.U + A.M = 177
A.F + A.M + 13 + 69 + A.F + A.M + 13 + A.M = 177
2A.F + 3A.M = 177 - 13 - 13 - 69
E.U + A.M + 29 + 3A.M = 82
A.M + 13 + A.M + 29 + 3A.M = 82
5A.M = 82 - 13 - 29
A.M = 40/5
A.M = 8
E.U = 8 + 13 = 21
A.F = (21 + 29) / 2 = 25
A.S = 177 - 25 - 21 - 8 = 123

Therefore, there are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

zimovet [89]

Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

$\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}$

So q will take 45 more minutes
