To write the 3 times table I will help you walk through it:-

3 × 1 = 3 + 0 = 3
3 × 2 = 3 + 3 = 6
3 × 3 = 3 + 3 + 3 = 9
3 × 4 = 3 + 3 + 3 + 3 = 12
3 × 5 = 3 + 3 + 3 + 3 + 3 = 15
3 × 6 = 3 + 3 + 3 + 3 + 3 + 3 = 18
3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21
3 × 8 =  3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24
3 × 9 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27
3 × 10 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 30
3 × 11 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 33
3 × 12 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 36

Hope i helped ya!! :P

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>

A cylinder is placed within a cube. The diameter of the cylinder is equal to the length of each side of the cube. What is the vo
pochemuha

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:

l = 10 ---- length of the cube

So, the volume of the cube is:

V_1 = l^3

V_1 = 10^3

V_1 = 1000

The volume of the cylinder is:

V_2 = \pi r^2h

The diameter (d) of the cylinder equals the length of the cube.

This means that:

d = l

d = 10

Divide by 2 to calculate the radius of the cylinder

r = \frac{10}{2}

r = 5

Also, the height of the cube is::

h =l

h =10

So, we have:

V_2 = \pi r^2h

V_2 = \pi \times 5^2 \times 10

V_2 = \pi \times 25 \times 10

V_2 = \pi \times 250

V_2 = 785.4

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

V = V_1 - V_2

V = 1000 - 785.4

V = 214.6

Hence, the volume outside the cylinder is 214.6 cubic inches

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed
lions [1.4K]

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.
