compute the thickness of each piece of paper. show your reasoning

Answers

Answer 1

Answer:

Derions answer is not correct becuase 500 x 0.015=7.5 inches.  If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.  

If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Answers

Answer:

y = 3x

Step-by-step explanation:

from the table slope or rate of change is

m = 6 - 0 / 2 - 0 = 6/2 = 3

m = 12 - 6 / 4 - 2 = 6/2 = 3

m = 18 - 12 / 6 - 4 = 6/2 = 3

so m = 3

y = mx + c

c is y intercept --> y value when x is 0

y = 0 = c

so line equation is y = 3x + 0

y = 3x

Answer:

B, or 3x.

Step-by-step explanation:

When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.

2 x 3 = 6

4 x 3 = 12

6 x 3 = 18

Therefore, your answer is 3x.

Gena wants to estimate the quotient of –21.87 divided by 4.79. Which expression shows the estimate using front-end estimation?
-21 ÷ 4
-21 ÷ 5
-20 ÷ 4
-20 ÷ 5

Answers

Answer:

-21/5 = -5.25 or -5

Step-by-step explanation:

It is so because I estimated the -21.87 to -21 because of the 8 being higher than five. I estimated the 4 to 5 because of the 7 being higher than five also.

-5.25

This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.

In your own words, explain to me what is absolute value? Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.

Answers

Answer:

It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.

This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.

Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.

The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.
