Answers

Answer 1

Answer:

2. yes; the equation can be written as y = kx; k = 1

Step-by-step explanation:

x-y = 0

That means x and y have to be the same value.

If you multiply a number by 1, you get the same thing.

If you multiply x by one, you get y (the same value).

Hope this helps!

The library has 3,121 magazines. Each bin holds 73 magazines. How many magazines will be in the partially filled bin?

Answers

Answer:

55

Step-by-step explanation:

3121/73=42 R55

Answer: 55 magazines will be in the partially filled bin.

Step-by-step explanation:

3,121 / 73 = 42.75, or 42 whole bins.

42 * 73 = 3,066

3,121 - 3,066 = 55

Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)

Answers

Answer:

we can see that the x or the first number in both are 2 so there is no distance there, where there is a distance is the y which to find out we can just do 2.5-1.2=1.3

the distance between the two points is 1.3

1.3 that is the answer yw

A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3

What is the minimum surface area that such a box can have?

Answers

Answer:

x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.

Step-by-step explanation:

Answer:

hi

Step-by-step explanation:

Let x = the length of the sides of the base and h = the height:

Volume = (area of base)(height)

V = x2h

2048 = x2h

2048/x2 = h

Surface Area = area of base + 4(area of vertical side)

SA = x2 + 4xh

Eliminate the h by using 2048/x2 = h:

SA = x2 + 4x(2048/x2)

SA = x2 + 8192 x-1

Take the derivative of SA wrt x, set it to zero, solve for x.  Plug that value of x into the surface area equation to find the minimum surface area.

The graph below shows the relationship between the number of ice cubes made and the number of ice trays used:

A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5. The values on the y axis are 0, 16, 32, 48, 64, 80. Points are shown on ordered pairs 0, 0 and 1, 16 and 2, 32 and 3, 48 and 4, 64. Only the point on the ordered pair 3, 48 is labeled as A. These points are joined by a line. The label on the x axis is Ice Trays. The title on the y axis is Ice Cubes.

Which statement best describes point A on the graph?

One ice tray makes 32 ice cubes.
One ice tray makes 48 ice cubes.
Three ice trays make 16 ice cubes.
Three ice trays make 48 ice cubes.

10/12 simplified 5/6

Answer:

A) [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

So solve, change the sign into multiplication and use the reciprocal of the second number.

To find the reciprocal,  flip the numerator and the denominator.

The reciprocal of 4/5 is 5/4.

So you have [tex]\frac{2}{3}[/tex]×[tex]\frac{5}{4}[/tex]

Multiply like a normal expression.

You get 10/12, which can be simplified to [tex]\frac{5}{6}[/tex]

Answer:

Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

           -38     -38

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

Answer:

Step-by-step explanation:

Question 1:

-7 = w + 5

- 5        - 5

-12 = w      

w = -12

Question 2:

-4p + 38 = 10

      - 38   - 38

-4p = -28

-----    -----       fraction bar... -4p divided by -4, -28 divided by -4
