Answer:

13) 2 g

14) 5,000 mL

15) 104,000 m

16) 160 mm

17) 5,600,000 mg

19) 0.25 km

Step-by-step explanation:

13. Convert 2,000 mg to g:

1 mg = 0.001 g

(2,000 mg * 0.001 g) / 1 mg = 2 g

14. Convert 5 L to mL:

1 L = 1000 mL

(5 L * 1000 mL) / 1 L = 5,000 mL

15. Convert 104 km to m:

1 km = 1000 m

(104 km * 1000 m) / 1 km = 104,000 m

16. Convert 16 cm to mm:

1 cm = 10 mm

(16 cm * 10 mm) / 1 cm = 160 mm

17. Convert 5.6 kg to mg:

1 kg = 1,000,000 mg

(5.6 kg * 1,000,000 mg) / 1 kg = 5,600,000 mg

19) Convert 250 m to km:

1 m = 0.001 km

(250 m * 0.001 km) / 1 m = 0.25 km

ozzi

Answer:

Step-by-step explanation:

2x+5y=12

3x+4y=11

---------------

3(2x+5y)=3(12)

-2(3x+4y)=-2(11)

-----------------------

6x+15y=36

-6x-8y=-22

-----------------

7y=14

y=14/7=2

2x+5(2)=12

2x+10=12

2x=12-10=2

x=2/2=1

x=1, y=2. (1, 2)

The mass of a cylinder made of barium with a height of 2 inches depends on the radius of the cylinder as defined by the function

svp [43]

Answer:

$r=22.07\ in$

Step-by-step explanation:

The correct function is

$m(r)=7.188\pi r^{2}$

we have

System of equations

$m=7.188\pi r^{2}$ -----> equation A

$m=11,000$ -----> equation B

Solve by substitution method

substitute equation B in equation A

$11,000=7.188\pi r^{2}$

Solve for r

Divide by 7.188π both sides

$r^{2}=\frac{11,000}{7.188\pi}$

square root both sides

$r=22.07\ in$
