- 3.92 is not an integer
790.17 is not an integer
40 is an integer
-12/19 is not an integer, it is a Rational number
Step-by-step explanation:
(x+2)(x+8) = x^2 +10x +16
(x^2 + 10x + 16)(x-1) = x^3+9x^2+6x-16, so the other dimension is x-1
Answer: ok?
Step-by-step explanation:
At 2:30, they are 70 miles away, at 2:45, they are 55 miles away.
That means, in 15 minutes, they traveled 15 miles....thats 1 mile per minute.
so 2:45....55 miles away...at 1 mile per minute = 2:45 + 55 minutes =
3:40. <== when they arrive at Grandma's house.
3:40 - 1:00 = 2:40.....it took 2 hrs and 40 minutes for the trip....thats 120 + 40 = 160 minutes <== =so the family lives 160 miles from Grandma's house
<span>The annual return on $400 in stock is 0.11*400 = $44
</span>
The total return you want is 0.09 * 1600 = $144
Let a be the amount invested at 12% and b be the amount invested at 6%
0.12a + 0.06b = 144 - 44
12a + 6b = 10000
a + b = 1200
Put those 2 equations together and solve for a and b:
12a + 6b = 10000
a + b = 1200
Using elimination, a = $466.67 and b = $733.33
<span>So, out of an additional $1200, invest $466.67 at a rate of 12% and $733.33 at a rate of 6%</span>
