Answer:

r = 7 cm

Step-by-step explanation:

Given that,

Volume of the packing tube, V = 1761 cm²

The altitude of the tube, h = 11 cm

We need to find the radius of the packing tube. The volume of the the cylindrical shaped object is given by :

[tex]V=\pi r^2 h\\\\r^2=\dfrac{V}{\pi h}\\\\r^2=\dfrac{1761}{\pi \times 11}\\\\r=7.13\ cm[/tex]

or

r = 7 cm

So, the radius of the packing tube is 7 cm.

Step-by-step explanation:

[tex]y = a {b}^{x} \\ b = \frac{0.0006}{0.006} = 0.1 \\ a = 6 \\ y =6 \times {0.1}^{x} [/tex]

Answer:

62%

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

Given the function :

h(t) = t² + 2

From t = 5 to t = 8

when, t = 5

h(5) = 5² + 2

h(5) = 25 + 2

h(t) at t = 5 ; equals 27

when, t = 8

h(5) = 8² + 2

h(5) = 64 + 2

h(t) at t = 8 ; equals 66

Net Change :

h(8). - h(5)

66 - 27 = 39

Step-by-step explanation:

Answer:

The volume of a cone is pi multiplied by the radius squared times the height divided by three.

Step-by-step explanation:

If 3.14 is used for pi:

V = 3.14 * 15^2 (9/3)

   = 3.14 * 15^2 (3)

   = 3.14 * 225 * 3

   = 706.5 * 3

   = 2,119.5 cm cubed

If 3.14 is not used for pi:

V = pi * 15^2 (9/3)

   = pi * 15^2 (3)

   = pi * 225 * 3

   = 706.8583470577035 * 3

   = 2,120.57504117311 cm cubed

Answer:

A, C, and E are true

Answer:

55 guests

Step-by-step explanation:

131 = 21 + (2x)

subtract 21 from both sides

110 = 2x

x = 55 guests

Answer:

55 guests

Step-by-step explanation:

if he can afford to spend a total of $131, then you subtract the birthday cost ( $21 ) and divide the answer of those two ( $110 ) by $2 ( the amount for each guest ) which is 55, therefore, 55 is the largest number of guests Jeffrey can afford.

Move the seven underneath the 52 and leave the x on one side.

x = 29.37853107

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

So basically just do 112 divided by 4 to find the length of each side. Then from there minus that one side by 4 to get what you need x to be to be the length of the one side. One side is 28. Also...

Answer:

the slope of the line=0/6

Step-by-step explanation:

you can use the formula `y-y/`x-x, where (-8,5)=(x,y) and (-2,5)=(`x,`y)

5-5/-2--8

5-5/-2+8

0/6

Therefore, the slope of the line=0/6

Answer: The slope is 0 (undefined)

Step-by-step explanation:

A simple way to find slope of a line when given two points is to employ the use of a formula that essentially calculates it for you.  This formula is (y2-y1)/(x2-x1) with y representing the y coordinates and x representing the x coordinates.  For example you could write this as (5-5)/(-2-(-8)) which of course gives you an answer of 0 (undefined) because anything divided by 0 is automatically 0 (undefined) and as we see in our formula we are subtracting 5 from 5.

Speed = distance/time

1. Logan swam 750 meters in 1/3 of an hour

Logan's speed is:

2. Mila swam 2/3 of Logan's distance:

Mila's speed is:

3. The difference is:

Logan is faster by: 2250 - 2000 = 250 meters/hour

Answer:

300,000,000

Answer:

3 = x

Step-by-step explanation:

4 (10-x) = 8x + 4

Distribute

40 -4x = 8x+4

Add 4x to each side

40 -4x+4x = 8x+4 +4x

40 = 12x+4

Subtract 4

40 -4 = 12x+4-4

36 = 12x

Divide each side by 12

36/12 = 12x/12

3 = x

Actually Welcome to the Concept of the rectangles.

here, l = 10 , b = 7

hence, perimeter of rectangle = 2(l+b)

=> 2(10+7) => 2(17) => 34 units

hence the perimeter is 34 units.

The equation should be 105(0.15)+ x = 170 and the value of x is 154.25

Here we assume the hiking boots cost be x

So, the equation is

105(0.15) + x = 170

15.75 + x = 170

x = 170 - 15.75

x = 154.25
