so you for sure cross off the 1st and 3rd problem off and if you choose the last one your answer would be in th left side of the y axis so it the 2nd answer
Recall that the volume of a cube equals (side)^3. We can create an equation to model this.
1728 in^3 = (side)^3
We can get the cube root of both sides.
12 in = side
Each side is 12 inches long.
Answer:
21
Step-by-step explanation:
First you have to solve for x in the equation 2x + 9 = 23. Cancel 9 on both sides. You cancel 9 by subtracting 9 on the left side and on the right side:
23 - 9 = 14.
Now, you have 2x = 14. To isolate the variable, divide by 2 to cancel out 2.
14 / 2 = 7.
This will give you x = 7. Now that you know what x equals, you can substitute x in 3x. This would make it 3(7), or in other words 3 x 7.
3 x 7 = 21.
This means that 3x would be equal to 21. Hope it helps!
Because the number increase by a percentage this is an exponential growth problem.
The equation for exponential growth is :
Total = start value x ( 1 + percent) ^ time
Using the information from the problem:
2011-2005 = 6 years.
Total = 23 x (1 + 0.72)^6
Total = 23x 1.72^6
Total = 595.52 = 596 total people
