You do: 1/2 job/hr
Your friend does: 1/3 job/hr
Together: (1/2 + 1/3) job / hr
= (3/6 + 2/6) job/hr
= 5/6 job/hr .
Since you do 5/6 job/hr, the corresponding
inverse unit rate is
6/5 hr/job
= 1 and 1/5 hr/job
= 1.2 hours/job
= 1 hour 12 minutes per job.
Answer:
5
Step-by-step explanation:
b = 13 - 8 = 5
It's important that you use the correct symbol to indicate exponentiation.
<span>f(x) = 0.4(3)x f(x) = 3(0.5)x f(x) = 0.8(0.9)x f(x) = 0.9(5)−x should be written as:
</span><span>f(x) = 0.4(3)^x f(x) = 3(0.5)^x f(x) = 0.8(0.9)^x f(x) = 0.9(5)−x.
Please double-check that last problem, as I am unsure of whether you meant 0.9^5 or (0.9)(5).
f(x) = 0.4(3)^x is definitely an exponential function.
Please try again. Do those problems that you can do an ask questions about the others.

8x^2 - 56 + 48
Use the distributive property
8(x^2 - 7 + 6)
Find two factors of 6 that add to -7
The two factors are -1 and -6.
8(x -1)(x-6)
Have an awesome day! :)
Answer:
100 lightbulbs
Step-by-step explanation:
Basically find the percentage of lightbulbs that are bad. 5/136. So about 3. 6 percent. I'm going to use a more exact form of this percent for my calculations though. Now use the decimal for of this (0.036....) and multiply it by 2720. Using my exact decimal, the answer just so happened to be exactly 100. So there will be 100 defective lightbulbs per day. (Teachers are a stickler for units, so don't forget them if it's for a teacher)
Hope this helps!
