​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.

80% of the 6th graders at Harrison Middle are going on a field trip to the Museum. There is a total of 685 students in 6th grade
Oliga [24]
80%=.8, .8*685=548. This is the simple math that you need. For the percentages, move the decimal place two places to the left and then multiply by the number that you want to get the percentage of.

Ari is recording the number of laps he walks around the track each day, On Day 1, he walks 8 laps. On Day 2, his number of laps
alina1380 [7]

Step-by-step explanation:

to compare day 1 with day 2 :

100% = 8

1% = 100%/100

25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2

so, on day 2 he walks 8+2 = 10 laps.

on day 3 he walks then 10-1 = 9 laps.

so, now, to calculate the % decrease compared to day 2

100% = 10

1% = 100%/100 = 0.1

how many % is represented by this 1 lap he was walking less ?

1 / 1% = 1 / 0.1 = 10%

so he had a 10% decrease from day 2 to day 3.
