Suppose you are given a cube made of magnesium (mg) metal of edge length 2.15 cm. (a) calculate the number of mg atoms in the cube. (b) atoms are spherical in shape. therefore, the mg atoms in the cube cannot fill all the available space. if only 74 percent of the space inside the cube is taken up by mg atoms, calculate the radius in picometers of an mg atom. (the density of mg is 1.74 g/cm3, and the volume of a sphere of radius r is 4/3π r3.) enter your answers in scientific notation.

Simplify by combining like terms- 9a+3-2a

Answers

Answer: 7a+3

Step-by-step explanation:

9a and 2a are two like terms that we can combine. Because there is a minus sign in front of the 2a, we should subtract 9a from 2a to get

7a. Then because the 3 has plus sign in front of it, we add 7a to 3. BUT because 3 a is NOT a like term, you don’t actually add it, so it looks like this: 7a+3. Hope this helped!
7a+3 because the 9 and 2 are from the same family since they both have a so u combine then and u cant combine 3 with anything so that’s left over

Help?? reading a tape measure​

Answers

Answer:

1. 11 3/4

2. 29 7/16

3. 21 3/8

Step-by-step explanation:

The numbers against the longest marks are the integer portion of the measurement. Tapes that measure inches are marked this way, so we'll presume these are inch measurements. (There is nothing in your picture indicating the unit of measure.)

Each interval between two inch marks is divided into 16 equal parts. The marks get progressively shorter for 1/2, 1/4, 1/8, and 1/16 units. As you would expect, the mark halfway between the numbers is at 1/2 unit, or 1/2 inch more than the smaller of the two integers. The next shorter mark midway in the space between the 1/2 mark and the integers marks 1/4 unit. As you know 1/2 of 1/2 is 1/4. The second-shortest mark is at intervals of 1/8 either side of the 1/4 and 1/2 marks.

Equivalent fractions for numbers of 16ths also give you a clue as to how to read this.

integer inches . . . longest mark

1/16 = 1/16 . . . shortest mark

2/16 = 1/8 . . . second shortest mark

3/16 = 3/16

4/16 = 1/4 . . . third shortest/longest mark

5/16 = 5/16

6/16 = 3/8 . . .second shortest mark

7/16 = 7/16

8/16 = 1/2 . . . second longest mark

__

1. The middle mark between 11 1/2 and 12 is 11 3/4, so that is the measure indicated here.

__

2. The smallest mark is 1/16 less than 1/2, so is 7/16 more than 29. The measure shown is 29 7/16.

__

3. The second smallest mark is 2/16=1/8. This amount less than 21 1/2 (or more than 21 1/4) is 21 3/8.

While it is common for inch rulers to be divided into 16ths, some specialty rulers have other divisions. Engineering rulers may be divided into 10ths, 20ths, 30ths, 40ths, 50ths, and 60ths (6 scales). Architectural rulers are divided in such a way as to make certain scale factors easy to read. It is not uncommon for the first inch or two to be divided into much smaller divisions, 100ths or 64ths or 32nds, for example.

a map of barn is shown in coordinate plane in which the coordinates are measured in yards. The map shows the barn a (4,6). A well is dug at (4, y). What are the two values of y such that the barn is 70 yards from the well

Answers

Answer:

The values of y such that the barn is 70 yards from the well are y=76 or y=-64

Step-by-step explanation:

Distance in the Plane

Given two points in a rectangular system of coordinates (a,b) and (c,d) the distance measured between them is calculated with the formula

d=√((c-a)^2+(d-b)^2)

The barn is located at (4,6) and the well is located at (4,y). The value of y must be calculated in such a way the distance between the barn and the well is 70 yards. Thus, the equation to solve is

70=√((4-4)^2+(y-6)^2)

Operating

70=√((y-6)^2)

When taking the square root we must be careful for it has two signs:

70=\pm (y-6)

Rearranging

y-6=\pm 70

which yields to these solutions

y-6=70

\boxed{y=76}

And also

y-6=-70

\boxed{y=-64}

The values of y such that the barn is 70 yards from the well are y=76 yards or y=-64 yards
