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)
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
The answer is 0.41 but what do you not understand? Hope I helped!
Answer: 1/2
Step-by-step explanation: rise/ run
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 ...

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.
