Answer:

Its 189000

Step-by-step explanation:

630000 divided by 10/3

630000 times 3

thats 1890000

1890000/10 = 189000

hope this helped

Ok assuming that when he buys the fabric, he cuts pieces off to make it fit, but doesn't sow them in other places to make up the lost area

so
first find the area of tablecloth he needs to buy
area=pir^2
diameter=32
d=2r
r=d/2
r=32/2=16
adds 5 inches extra
16+5=21
r=21
area of cloth=pi21^2
are of cloth=441pi
aprox pi=3.14
area=441 tmes 3.14
area=1384.74

buys cloth with width of 50 and legnth of x
so we need 2 things
1. area of cloth bought>area of tablecloth
2. legnth &width must both be greater or equal to the diameter of the tablecloth (so we can make a circle fit)

new diameter=32+5+5=42 (2 sides)
so
l and w must both be greater than or equal to 42

50l>1384.74
divide both sides by 50 to find legnth
l>27.6948
but the legnth must be also greater than or equal to 42
so make l=42 for min legnth
area of cloth bought=lw=42 by 50=42 times 50=2100

so we do

area wasted=area bought-area needed
area needed=area of tablecloth=1384.74
area bought=2100
area wasted=2100-1384.74
area wasted=715.26 in^2

answer is wasted area=715.26 square inches

4x + 3y - z = -6<br> 6x - y + 3z = 12<br> 8x + 2y + 4z = 6

Answer:

(x, y, z) = (1, -3, 1)

Step-by-step explanation:

Any number of calculators and/or web sites can be used to solve this system of equations. It can be helpful to familiarize yourself with your graphing calculator's capabilities in this area. The solution from one such site is shown below:

(x, y, z) = (1, -3, 1)

Both y and z show up in these equations with coefficients that have a magnitude of 1. This means you can easily use one of those equations to create a substitution for y or for z.

Using the first equation to write an expression for z, we have ...

z = 4x +3y +6

Substituting that into the second and third equations gives ...

6x -y +3(4x +3y +6) = 12 ⇒ 18x +8y = -6

8x +2y +4(4x +3y +6) = 6 ⇒ 24x +14y = -18

Now, we can subtract 4 times the first equation from 3 times the second to eliminate x:

3(24x +14y) -4(18x +8y) = 3(-18) -4(-6)

10y = -30

y = -3

Substituting into the first equation (of the equations in x and y), we have ...

18x +8(-3) = -6

18x = 18

x = 1

Finally, substituting into the equation for z gives ...

z = 4(1) +3(-3) +6 = 1

The solution is (x, y, z) = (1, -3, 1).

The equations can also be solved using Cramer's rule, elimination, matrix methods, and other means. When solving by hand, the method of choice will often depend on what you're familiar with and what the coefficients are.
