Now, this is something called math.

21775-16925=4850

Yep. Go do some studying, it might help you. Also, this isn't middle school math, please post it under the relative category (that being kindergarten).

2x+y=8 y+3z=5 z+2w=1 5w+3x=9 Find the solution to each variable

morpeh [17]

Answer:

w = 0, x = 3, y = 2, z = 1

Step-by-step explanation:

You can use each equation to write an expression that will substitute into the next equation.

y = 8 -2x . . . . from the first equation

8 -2x + 3z = 5 . . . . . substituted into the second equation

z = (-3 +2x)/3 . . . . . solved for z

(-1 +2/3x) +2w = 1 . . . . . substituted into the third equation

w = (2 -2/3x)/2 . . . . . solved for w

5(1 -1/3x) +3x = 9 . . . . . substituted into the last equation

4/3x = 4 . . . . . simplified, 5 subtracted

x = 3 . . . . . . . . multiply by 3/4

w = 0 . . . . . . . .value of x substituted into equation for w

z = 1 . . . . . . . . value of x substituted into equation for z

y = 2 . . . . . . . .value of x substituted into equation for y

The solution is (w, x, y, z) = (0, 3, 2, 1).

Answer: ln ( 40) *100

Step-by-step explanation:

Substituting 140 in the equation,

140 = 100 + e^(.01q)

40 = e^(.01q)

Take the natural log of bot hsides

ln ( 40) = .01q

q= ln ( 40 ) * 100

Find the area A of the sector of a circle of radius 50 feet formed by the central angle

kozerog [31]

Answer:

$A=6250\ feet^2$

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, $\theta=5\ radian$

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

$A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2$

So, the area f the sector of the circle is $6250\ feet^2$ .
