2000 should be it I'm pretty sure
Answer:
b) $49
Step-by-step explanation:
The question here is not if Alexis can mow the lawn faster or slower than the person who hires (actually, the time that the person hired took to mow the lawn is irrelevant).
The important part is the time Alexis can save hiring someone:
- Alexis mow her lawn in 30 minutes.
- Alexis earns $100 an hour. Then 30 minutes of her time is worthy $50.
Then, paying $50 or less is a good choice for Alexis.
Therefore the answer is b) $49.
Answer:
Factor form of the equation makes it easiest to see the zeros of the function.
Step-by-step explanation:
f(x)=(x−4)(x−6), because you can see when each factor is equal to zero.
Just equate the factor with zero and you will get its zeros.
f(x)=(x−4)(x−6)
Let f(x)= 0
Therefore
(x−4)(x−6) = 0
Therefore
(x−4) = or (x−6)= 0
Therefore, x = 4 or x = 6
Hence, 4 and 6 are the zeros of the given function.
I think it's 7/9 .. try it
Answer:
3. rolling a sum of 20 with two standard dice
Step-by-step explanation:
If something has a probability of 0 then there is no chance of it happening
A standard die goes up to 6. The max sum you can get by rolling two dice would be 12 as 6 + 6 = 12. So you have no chance of rolling a sum of 20 with two standard dice therefore the probability would be 0.
