ABCD is a square . if the coordinates of three of its vertices are A(-1,2a), B(a,2a), C(a,0), find the coordinates of D. BC is obviously 2a (it's a vertical line) then AB must be 2a (notice AB is horizontal) so BC = AC because it is a square 2a = a+1 a=1
Answer:
Hmm I think D but don't take my word for it just a guess
Step-by-step explanation:
Answer: there are 50 humans and 24 horses.
Step-by-step explanation:
Let x represent the number of humans in the horse racing area.
Let y represent the number of horses in the horse racing area.
He counted 74 heads. A human has one head and a horse also has one head. It means that
x + y = 74
He counted 196 legs. A human has 2 legs and a horse has 4 legs. It means that
2x + 4y = 196 - - - - - - - -- - -1
Substituting x = 74 - y into equation 1, it becomes
2(74 - y) + 4y = 196
148 - 2y + 4y = 196
- 2y + 4y = 196 - 148
2y = 48
y = 48/2 = 24
x = 74 - y = 74 - 24
x = 50
Answer: $115,012,850.8
Step-by-step explanation:
given data:
cash out amount in 1993 = $163,882,660
no of years = 7
inflation adjustment carried out on the amount would yield $163,882,660. in 1993 is equal to $115,012,850.8 1987.
This is because the Annual inflation grew over this period at a pace 4.26%.
= 4.26/100 * $163,882,660
= 0.0426 * $163,882,660 * 7
= $48,869,809.21
$163882660 – $48,869,809.21
= $$115,012,850.8
0.06 times 96 equals 5.76
