Answer:
45
Step-by-step explanation:
As a first rough estimate: divide 390 by 10, obtaining 39.
Another reasonable approximation could be obtained by dividing 450 by 9 and 360 by 9, obtaining 50 and 40. Since 390 is roughly halfway between 360 and 450, estimate that the quotient is approx 45 (halfway between 40 and 50).
Answer:
Step-by-step explanation:
8.935e+6
Let h be horses
let s be sheep
h + s = 28
6s = h
plug h into eq’n one
(6s) + s = 28
7s = 28
s = 4
plug s into eq’n 2
6(4) = h
24 = h
therefore there are 24 horses and 4 sheep
Combining like terms: -23x + 9y
Answer:
The answer is 3054.8
Step-by-step explanation:
V = 4/3 × 22/7 × 9 × 9 × 9
V = 4 × 22/7 × 3 × 81
V = 4 × 22 × 243/7
V = 21384/7
V = 3054.8
Thus, The answer is 3054.8
