Write the number 0.000938 in scientific notion.
ss7ja [257]
<span>0.000938 in scientific notion.

First we need to move the decimal to its right and we need a number which is between 1-10. 

0.000938
00.00938
000.0938
0000.938
00009.38

We moved the decimal 4 times and to the right so it will be negative. -4.


9.38 </span>× 10^-4

Scientific notation of 0.000938 is 9.38 × 10^-4.

Check:-

9.38 × 10^-4 = <span>0.000938
</span>0.000938 = <span>0.000938
</span>Correct!

<span>Scientific notation of 0.000938 is 9.38 × 10^-4.</span>

Solve the simultaneous equations
Contact [7]

Answer:

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Step-by-step explanation:

Given equations are:

3x+4y=30\ \ \ Eqn\ 1\\3x-y=15\ \ \ \ Eqn\ 2

There are three methods to solve simultaneous equations

  1. Elimination
  2. Substitution
  3. Co-efficient method

We will use the elimination method as the coefficients of x in both equations are already same

Subtracting equation 2 from equation 1

3x+4y - (3x-y) = 30-15\\3x+4y-3x+y = 15\\5y = 15\\\frac{5y}{5} = \frac{15}{5}\\y = 3

Putting y = 3 in equation 2

3x-3 = 15\\3x = 15+3\\3x = 18\\\frac{3x}{3} = \frac{18}{3}\\x =  6

Hence,

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

phillip bought 12 used cds and dvds.cds cost $2 each,and dvds cost $3 each.he spent $31,not including tax.how many dvds did phil
inessss [21]
Let c and d be the number of cds and dvds respectively.

c+d=12

c=12-d

The we are told that:

2c+3d=31, using c found above in this equation gives you:

2(12-d)+3d=31

24-2d+3d=31  

24+d=31

d=7

So Phillip bought 7 dvds.

check...

3*7+2(12-7)=31

21+2(5)=31

21+10=31

31=31
