Answer:

Step-by-step explanation:

#6  

a       n

---- = ----    Solve for a.  Note that if we multiply both sides of this equation by

m       p                                     n

                  m, we get a = m * ----

                                                  p

                                                                                    m*n

                    and this simplifies to a = mn/p or  a = ---------

                                                                                       

#7     Solve mx = np for x.  We want to isolate x on the left side.  Dividing

both sides by m isolates x on the left and adds the divisor m on the right:

                            np

mx = np  =>  x = ------

                              m

#8    Solve c - x = d + r  for x       We want -x alone on the left side.  Accomplish this by subtracting c from both sides, obtaining:

-x = d + r - c.       Now multiply both sides by -1, obtaining x = -d - r + c

What's (7 x 100) + (4 x /100) + (8 x 1/1000) in standard form?
IceJOKER [234]

Answer:

(7*100) can be written as 7*10^2

4 * / 100 i don’t know

if it was 4 * 100 then it’s 4*10^2

if it was divided then it’s 4*10^-2

8* 1/1000 = 8/1000 = 8*10^-3

add together to get 1.100008 * 10^3 (if it was 4*100)

or 7.00048 * 10^2 ( if it was 4/100)

Can u guys PLEASE answer question g. THIS IS URGENT
ivann1987 [24]

Answer:

Laura is 8

Step-by-step explanation:

let Laura's age now be x then Daniel's age is 2x

4years ago

Laura was x - 4 and Daniel 2x - 4, thus

2x - 4 = 3(x - 4) ← 3 times Laura's age

2x - 4 = 3x - 12 ( subtract 2x from both sides )

- 4 = x - 12 ( add 12 to both sides )

8 = x

Thus Laura is 8 years old

Why does log 10 100,000 equal to 5?
kykrilka [37]

Explanation:

A logarithm is an exponent. An integer exponent tells you the number of times the base is a factor in the product:

  100,000 = 10×10×10×10×10 = 10⁵

so, log₁₀(100,000) = log₁₀(10⁵) = 5, the exponent of the base.

__

You know that 10⁰ = 1 and 10¹ = 10. Since the logarithm is the exponent of 10, the log of a number between 1 and 10 is expected to be between 0 and 1.

You may also know that ...

  10^{\frac{1}{2}}=\sqrt{10}\approx 3.1623

That is, log₁₀(3.1623) = 0.50000. Just as the log of a number near 3 is between 0 and 1, the log₁₀ of any number between 1 and 10 will be between 0 and 1.

The number you're asking about, 5, has a logarithm that is about 0.69897.
