Answers

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

-4       -4

p = 7

Question 3:

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

- 7    =  - 5

-----      ----- b

 2          4

4        -7          -5          4

----  x -----   =  ------  x ----- b

-5        2           4         -5

----     = b

-10

-28                       2          14

-----   divided by ----   =  -----

A property's value decreased by 15%. If is was worth 189,000, what is worth now?

Answers

15% of 189000 = [tex] \frac{15}{100} \times 189000 = 28350 \\ [/tex]

So, now it's worth[tex] = 189,000 - 28,350 \\ = 160,650[/tex]

The current worth of the property is $160,650.

What is percentage?

Percentage, is a relative value indicating hundredth part of any quantity.

Formula for percent decrease

Percent decrease = ( decreased value/ original value) × 100

Therefore,

Decreased value = Original value - new value

According to the question

We have

Percent decrease = 15%

Original value of the property = $ 189,000

So, 15% 0f $189,000 = [tex]\frac{15}{100}[/tex] × 189000

⇒ 15% of 189000 = $28350

Therefore, the decreased value of the property = $189000 - $28350

Decreased value of property = $160,650

Hence, the current worth of the property is $160,650.

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.
