Answer:
10^20
Step-by-step explanation:
So in this word problem, we have to multiply 10^13 bacteria cells on a single person by the 10^7 of people.
Always remember this, when you have exponenets with the same bases, and the question asks for multiplying and dividing exponents, you just need to add and subtract the exponent. 
So in this case, we will just add since it calls for multipactation.
So we need to solve:
10^13+7
This will just equal:
<u>10^20 power</u>
Hope this helps ;)
 
        
             
        
        
        
Answer:
 where 1 < a ≤ 9
  where 1 < a ≤ 9
The EXPONENT USED BY PETER is 7 in all the possible cases. 
Step-by-step explanation:
Let us assume the needed number is M.
Also, given: 
The needed number is GREATER than 10 Million.
⇒ M  > 10 Million
⇒ M > 10,000,000
⇒ M >  ...... (1)
  ...... (1)
The needed number is SMALLER than 100 Million.
⇒ M  <  100 Million
⇒ M < 100,000,000
⇒ M  <   ...... (2)
  ...... (2)
Comparing (1) and (2) we can see that M can have more than 7 zeroes after 1 but LESS than 8 zeroes after 1.
So, the possible values of M can be:
 where 1 < a ≤ 9
  where 1 < a ≤ 9
So, the EXPONENT USED BY PETER is 7 in all the possible cases. 
 
        
             
        
        
        
Answer:
$2000 was invested at 5% and $5000 was invested at 8%.
Step-by-step explanation:
Assuming the interest is simple interest.
<u>Simple Interest Formula</u>
I = Prt
where:	
- I = interest earned.
- P = principal invested.
- r = interest rate (in decimal form).
- t = time (in years).
Given:
- Total P = $7000
- P₁ = principal invested at 5%
- P₂ = principal invested at 8%
- Total interest = $500
- r₁ = 5% = 0.05
- r₂ = 8% = 0.08
- t = 1 year
Create two equations from the given information:


Rewrite Equation 1 to make P₁ the subject:

Substitute this into Equation 2 and solve for P₂:





Substitute the found value of P₂ into Equation 1 and solve for P₁:



$2000 was invested at 5% and $5000 was invested at 8%.

Answer:
Step-by-step explanation:
Emery is paid 15 dollars an hour and she worked 38 hours
15*38=570 dollars just from the hourly wage
the commission is 2.25% and her sales were 3,200 dollars
(3200*2.25)/100=72
total=570+72=642
 
        
             
        
        
        
Not sure i remember this but i think radius is like half of the diameter. it’s a line from the center, to a side of the circle. in this situation, line RO would be representing the radius.
answer: D, line RO
hope this helps :)
