Gretchen Made A Paper Cone To Hold A Gift For A Friend. The Paper Cone Was 14 Inches High And Had Aradius

Answers

Answer 1

Answer:

268.0 in²

Step-by-step explanation:

refer to attached graphic as reference

volume of cone, V = (1/3) πr²h

in our case, we are given r = 4" and h = 16"

substituting this into equation:

V = (1/3) πr²h

=  (1/3) ·(3.14) · (4)²· (16)

= 267.94667 in²

= 268.0 in² (nearest tenth)

Answers

Answer:

Step-by-step explanation:

sir in the graph every point is (X,Y) so you should choose consecutive random numbers for the X values for the first point after that put the values you choose In the equations so now you have just numbers in the equation .. add, subtract and multiply at the end you will get a value .. ok this Y for the first point .. mark this point on the graph and continued this process until it reached at least 3 points, and connected between them.

Note : do this with each equation separately and do not connecte between two points for two different equations

the equation with x will become as line

the equation with x² will become as arch

after you finsh drwaing see the points that the tow equation are touching within and write them. Usually it is two points

Step-by-step explanation:

First, set the equations as equal to eachother because both equal y:

[tex]x^2-6x-7=x+1[/tex]

Now, solve to get everything on one side of the equation so that the other side of the equation is set to 0:

[tex]x^2-7x-8=0[/tex]

Now use the sum product pattern:

[tex]x^2+x-8x-8[/tex]

(as you can see, the above equation is equivalent to the previous equation, but there are now four values instead of three)

Now take the common factor from the two pairs:

[tex]x(x+1)-8(x+1)[/tex]

Rewrite in factored form:

[tex](x-8)(x+1)[/tex]

Now to get both values of x, set each factored equation to 0 and solve for x (becuase remember, the equation still equals 0):

[tex](x-8)=0\\x=8[/tex]

[tex](x+1)=0\\x=-1[/tex]

NOW that we have both values of x, we can subsitute them into EITHER equation and solve to get the corresponding y values:

[tex]y=(8)+1\\y=9[/tex]

[tex]y=(-1)+1\\y=0[/tex]

So that's how we solve to get these coordinates: (8,9) & (-1,0).

Good luck on your final and I hope I was able to help :)

The character in our video multiplied the original value for black paint by 5 to get the new value for black paint. So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.

Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.

Step-by-step explanation:

We know that the recipe requires an eighth of a cup of flour (1/8 or 0.125) but in total Steve has 2 and a half, that is (2 1/2 or 2.5). To know the result we must divide the total amount by what is needed for 1 recipe, that is:

2.5 / 0.125 = 20

Which means that Steve with the flour he has can make the same recipe a total of 20 times

please for 100 points

Answers

Answer:

1728

Step-by-step explanation:

Strategic Advice: You can tell from the length of the question that you can simply skim the first couple of sentences. You also need to make sure you answer the right question (how many masks the hospital would receive if it ordered all of the boxes of 144 the supplier has in stock).

Getting to the Answer: Create a system of linear equations where x represents the number of boxes with 48 masks and y represents the number of boxes with 144 masks. The first equation should represent the total number of boxes, x + y = 35. The second equation should represent the total number of masks. Because x represents boxes with 48 masks and y represents boxes with 144 masks, the second equation is 48x + 144y = 2,832. Now solve the system using substitution.

Answer:

1. 5.25 - 5= 0.25

2. 5.5 - 4 = 1.5

Step-by-step explanation:

Find the mean: Add all values Divide by how many numbers there are

Last week:

2 + 3 + 3 + 3 + 4 + 4 + 7 + 7 + 7 + 7 + 8 + 8 = 63

63/12 = 5.25

This week:

2 + 2 + 2 + 3 + 3 + 4 + 4 + 6 + 8 + 8 + 9 + 9 = 60

60/12 = 5

Last week mean - This week mean:

Mean of strikes last week - Mean of strikes this week =

5.25 - 5 = 0.25

Find the Median:   Put all values in order Find the middle value  (If there are two numbers in the middle then find the mean of the two values)

Last week:

2 3 3 3 4 4 7 7 7 7 8 8

4 + 7 = 11

11/ 2 = 5.5

This week:

2  2  2  3  3  4  4 6  8  8  9  9

4 + 4 = 8

8/2 = 4

Last week median - this week median:
