You have a gas with a density of 4.8 grams per Liter and a molar mass of 75.3 grams per mole. How many liters of gas do you have
Andre45 [30]

d = √((x1 - x2)2 + (y1 - y2)2)  

( -2 , 5 )   ( 12 , -1 )    

  ↑    ↑         ↑     ↑      

 x1    y1        x2    y2  

d = √((-2 - 12)2 + (5 - (-1))2) = √((-14)2 + 62) = √(196 + 36) = √232 = 2√58 ≈ 15.23

sertanlavr [38]

Answer:

The answer to your question is:

a) 31.75 cm

b) 0.475 miles

c) 2.44 yards

d) 11496.04 inches

Explanation:

Convert

a)           12.5 in to cm

         1 in ------------------- 2.54 cm

       12.5 in ----------------    x

            x = 12.5(2.54)/1 = 31.75/ = 31.75 cm

b)          2513 ft to miles

           1 mile -------------- 5280 ft

           x miles ------------ 2513 ft

        x = 2513(1)/5280 = 0.475 miles

c) 2.23 m to yards

              1 m -------------   1,094 yards

            2.23 m ----------     x

       x= 2.23x1.094/1 = 2.44 yards

d)  292 m to inches

            1 m ---------------- 39.37 inches

          292 m -------------     x

    x = 292 x 39.37/1 = 11496.04 inches

why is whenever one raised to the power of any exponent 1 and why is 0 raised to the power of any exponent 1
IceJOKER [234]
When you use exponents, think of it like this. 1 squared is 1 x 1. 1 cubed is 1 x 1 x 1. And 1 to the power of 4 is 1 x 1 x 1 x 1. And so on. You basically just multiply them by themselves. 0 to the power of any exponent is 1, well that's just a rule. It doesn't make much sense but it's easy to remember and I wouldn't worry about it.
