Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:


v = \pi \times  {r}^{2}  \times h


To find radius just divide diameter with 2.

v = \pi \times   {2}^{2}  \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}


Now just division:

28260 \div 75.4 = 374.8

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

What are the zeros of the quadratic function f(x) = 6x2 + 12x – 7?
zalisa [80]

we have

f(x) = 6x^{2} + 12x -7

To find the zeros equate the function to zero

6x^{2} + 12x -7=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

7= 6x^{2} + 12x

Factor the leading coefficient

7= 6(x^{2} + 2x)

Complete the square. Remember to balance the equation by adding the same constants to each side

7+6= 6(x^{2} + 2x+1)

13= 6(x^{2} + 2x+1)

Rewrite as perfect squares

13= 6(x+1)^{2}

(13/6)=(x+1)^{2}

square root both sides

x+1=(+/-)\sqrt{\frac{13}{6}}

x=-1(+/-)\sqrt{\frac{13}{6}}

x1=-1+\sqrt{\frac{13}{6}}

x2=-1-\sqrt{\frac{13}{6}}

therefore

the answer is

The zeros of the quadratic function are

x=-1+\sqrt{\frac{13}{6}} and x=-1-\sqrt{\frac{13}{6}}

Carly owns a T-shirt shop. She pays $2.25 for each shirt.
diamong [38]

Answer:

Total number of T-shirts= 200

Cost per T-shirt (without shipping ) = $2.80

Shipping cost per t-shirt ; 5% of a T-shirt = 0.05 *2.80 = $0.14

Total cost of T-shirt (shipping included) = 2.80 +0.14 = $2.94

Markup = 150% of total cost = 1.50 * 2.94 = $4.41

To get the price at which Michelle will sell each T-shirt , add total cost  to the markup; 2.94 +4.41 = 7.35.

Therefore, selling price will be $7.35

Which graph matches the equation y+3=2(x+3)?
Vlad1618 [11]

Answer:

The graph that includes points (-3,-3) and (0,3)

Step-by-step explanation:

In the pictures attached, the options are shown.

The equation:

y+3=2(x+3)

has the point-slope form, which is:

y-y₁=m(x-x₁)

where (x₁, y₁) is a point on the line and <em>m</em> is its slope. This means that (-3,-3) is on the line. To know the y-intercept of the line, we have to replace x = 0 into the equation, as follows:

y+3=2(0+3)

y+3 = 6

y = 6 - 3

y = 3

Then, point (0, 3) is on the line.
