It is 2 4/5, 2 4/5 is 2.8, 4/5 is greater than 3/4
Answer:
46. <u>(3) 29</u>
47. <u>(1) y = -4x + 3</u>
48. <u>(3) 3</u>
49. <u>(3) -1/2</u>
50. <u>(4) 25x - 75</u>
Step-by-step explanation:
<u>Question 46</u>
- Let red marbles be 2x + 3 and black marbles be x
- 2x + 3 + x = 42
- 3x = 39
- x = 13
- No. of red = 2(13) + 3 = 29 marbles
- <u>(3) 29</u>
<u></u>
<u>Question 47</u>
- Parallel to a line means the slope is the same
- <u>(1) y = -4x + 3</u>
<u></u>
<u>Question 48</u>
- For the expression to be undefined, the denominator has to be 0
- x - 3 = 0
- x = 3
- <u>(3) 3</u>
<u></u>
<u>Question 49</u>
- Slope = -4 - 1 / 4 + 6
- Slope = -5/10
- Slope = -1/2
- <u>(3) -1/2</u>
<u></u>
<u>Question 50</u>
- Total = 25x
- Left 3 boxes at home = -3x = -3(25) = -75
- <u>(4) 25x - 75</u>
The volume of a shape is the amount of space in it.
<em>The volume outside the cylinder, but inside the cube is 214.6 cubic inches</em>
The given parameter is:
---- length of the cube
So, the volume of the cube is:



The volume of the cylinder is:

The diameter (d) of the cylinder equals the length of the cube.
This means that:


Divide by 2 to calculate the radius of the cylinder


Also, the height of the cube is::


So, we have:





So, the volume (V) outside the cylinder is:



Hence, the volume outside the cylinder is 214.6 cubic inches

Answer:
7920
Step-by-step explanation:
you can use the binomial theorem obviously but you can also use symbolabs or wolframalpha and just solve it like that.
Answer:
4424 books
Step-by-step explanation:
After the revenue from each book pays for its own cost, it can contribute to the payment of the fixed costs. That "contribution margin" is ...
$25.50 -11.25 = $14.25
If each book sold contributes that much to the recovery of fixed costs, then the total number of books that must be sold to break even is ...
$63,042/($14.25/book) = 4424 books
4424 books must be produced and sold so production costs equal sales.
