Mathematics
1 answer:
kykrilka [37]4 years ago
4 0
Add 4x to both sides
0=-24x³+10x²+4x
factor out the -2x from everybody
0=-2x(12x²-5x-2)
factor
use ac method
12 times -2=-24
what 2 numbers multiply to get -24 and add to get -5?
-8 and 3
0=-2x(12x²+3x-8x-2)
0=-2x((12x²+3x)+(-8x-2))
0=-2x(3x(4x+1)-2(4x+1))
0=-2x(3x-2)(4x+1)
set each to zero
0=-2x
0=x

0=3x-2
2=3x
2/3=x

0=4x+1
-1=4x
-1/4=x

x=-1/4 or x=0 or x=2/3

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6
abruzzese [7]

Answer:

The largest  number of pyramids she can make from 20 bars of chocolate is:

  • <u>A. 180</u>

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

  • Volume of the bars = 6 in^3 * 20
  • <u>Volume of the bars = 120 in^3</u>

Now, you must find the volume of each pyramid, using the next formula:

  • Volume of a pyramid = 1/3 B * h

Where:

<em>B = area of the square base.</em>

<em>h = height of the pyramid.</em>

How these values are given in the problem, we only replace the values in the formula:

  • Area of a pyramid = 1/3 (1 in^2) * 2 in
  • <u>Area of a pyramid = 2/3 in^3</u>

Finally, we divide the volume of the bars in the volume of each pyramid:

  • Total number of pyramids = 120 in^3 / 2/3 in^3
  • <u>Total number of pyramids = 180</u>

If the measure of an angle is 27°,find the measure of its supplement.
finlep [7]

Answer:

153°

Step-by-step explanation:

1. If 27° is the supplement of another angle (or vice versa), that means both angles add up to 180.

2. To find the supplement of 27°, we simply subtract that number from 180.

  • 180 - 27
  • 153

Therefore, the supplement of 27° is 153°.
