Answer:
1. C) .4
2. B) 2 1/4
3. D) 3 5/8
Step-by-step explanation:
1. The question is asking what fraction (represented in decimal form) did Maria spend. To find this, divide 18/45 because Maria spent $18 of her $45. When you complete this calculation, you get .4
2. When you look at where the line ends, it's at the first quarter line after the 2, meaning that the line is 2 and one quarter or 2 1/4
3. 8 times 3 is 24, which is the closest multiple of 8 to 29. However, since there is still 5 left over (which still needs to be divided by 8) it would be represented by the mxed fraction.
Answer:
the answer is 3(x+2) = 3x=6
Step-by-step explanation:
3(x+2) = 3x+6 = 3 multiplies by x=3x 3 multiplied by 2=6 so it would be 3x+6
3x + 2x = x2(3+2)= 3x+2x= 5x its impossible to do 2x multiplies by 3 cause there is no similar variables there needs to be x in both
3x+2 - 3(x+2)= same as above there's no similar variables
-3(2+ )--6-3= this just doesnt work at all
Answer:
Dimensions: 0.4 by 3.2 by 1.2
Step-by-step explanation:
I'm assuming here that we are cutting out squares out of each of the metal's corners:
Let x = the length of each cut-out square,
Each base (of the desired net square folded) is 4-2x, and 2-2x respectively,
Volume = x(4-2x)(2-2x)
= 4x^3 - 12x + 8x
Now we take the derivative:
![\frac{d}{dx}\left[4x^3-12x^2+8x\right]\\\\= \frac{d}{dx}\left(4x^3\right)-\frac{d}{dx}\left(12x^2\right)+\frac{d}{dx}\left(8x\right)\\\\= 12x^2-24x+8](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%5B4x%5E3-12x%5E2%2B8x%5Cright%5D%5C%5C%5C%5C%3D%20%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%284x%5E3%5Cright%29-%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%2812x%5E2%5Cright%29%2B%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%288x%5Cright%29%5C%5C%5C%5C%3D%2012x%5E2-24x%2B8)
We equate to 0 (0 for max volume), and solve using the quadratic formula:
So we approximate the side lengths to be 1.6 and 0.4 respectively. But when we plug in 1.6 for x, we get the volume as negative. Therefore x has to be 0.4.
Side lengths: 0.4, 4-2(0.4) => 3.2, 2-2(0.4) => 1.2
It should be y1 - y2/x1 - x2 this is supposed to be a fraction
I end up getting -31 - 24/5 + 6 or -31 -24/5 - (-6)
