DOES ANYONE UNDERSTAND????

Answer:

let cost of each pound of trail mix be x any y respectively

For 2 pounds of trail mix and 5 pounds of jelly beans, the total cost is $10

2x +5y = 10.....(1)

For 8 pounds of trail mix and 3 pounds of jelly beans, the total cost is $23

8x +3y = 23.....(2)

2x +5y= 10 ....... × 4

8x +20y = 40.....(3)

8x +3y = 23 ( from (2))

(3) - (2)

17y = 17

y= 1

8x +3y = 23

8x +3 = 23

8x= 20

x= 2.5

Cost for each pound of trail mix= $2.5

Cost for each pound of jelly beans= $1

Is my solution correct?

Answer:

The area of the shaded sector is $51.2\pi \ units^{2}$

Step-by-step explanation:

I assume that the problem is

Find the area of the shaded sector of the circle with radius equal to 16 units

step 1

Find the value of x

we know that

$8x+2x=360\°$ -----> by complete circle

$10x=360\°$

$x=36\°$

The central angle of the shaded sector is 2x

$2(36\°)=72\°$

step 2

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=16\ units$

substitute

$A=\pi (16)^{2}$

$A=256\pi\ units^{2}$

step 3

Find the area of the shaded sector

we know that

A central angle of 360 degrees subtends an area of circle equal to $256\pi\ units^{2}$

by proportion

Find the area of the shaded sector by a central angle of 72 degrees

$\frac{256\pi}{360}=\frac{x}{72} \\ \\ x=256\pi *(72)/360\\ \\x=51.2\pi \ units^{2}$

A rectangular box with a square base and a cover is to be built to contain 640 cubic feet. If the cost per square foot for the b

mixer [17]

Answer:

$4800

Step-by-step explanation:

The cost is minimized when any pair of opposite faces of the box costs the same as any other pair. Since the top+bottom total $25 per square foot and the sides (left+right or front+back) total $20 per square foot, the area of a side must be 25/20 = 5/4 times the area of the top or bottom.

If we let x represent the length of one side of the square bottom, then 5/4x will be the height of the box. Its volume will be ...

(5/4x)(x²) = 640 ft³

x³ = (4/5)(640 ft³) = 512 ft³ . . . . . . multiply by 4/5

x = 8 ft . . . . . . . . . . . . . . . . . . . . . . . take the cube root

The base area is then (8 ft)² = 64 ft², and the cost of the top+bottom is ...

64 ft² × $25/ft² = $1600

The three pairs of opposite sides will cost 3×$1600 = $4800.

The minimum cost of the constructed box is $4800.

_____

You can also write an equation for the total cost in terms of x, the side length of the base. That cost function will be ...

c(x) = 15x² + 10x² + 10·4x(640/x²)

This simplifies to ...

c(x) = 25x² +25600/x

A graph shows the minimum is c(8) = 4800 (as above).

Algebraically, you can set the derivative to zero to find the value of x.

dc/dx = 0 = 50x -25600/x²

512 = x³ . . . . multiply by x²/50 and add 512

8 = x . . . . . . . take the square root. Same solution as above. <em>Cost is minimized when the side length of the base is 8 ft</em>.
