The formula is y=0.5m+20
You start (0,20) then for each mile you increase by 0.5.
Or
Since the x axis is by two, then every two miles you increase by 1 mile. So (0,20); (2,21); (4,22); (6,23); (8,24).
Answer:
Combine like terms: 18x + 15x = 33x
(45 + 33x + 6x2)
Step-by-step explanation:
The percentage of the radioactive isotope left is 25.0000%.
<h3>What is the half life?</h3>
The half life of a radioactive isotope is the time that will elapse before only half of the number of original isotopes will remain.
Now;
We are told that;
Half life (t1/2) = 55 days
Time taken (t) = 115 days
Ratio of isotope remaining = N/No
Thus;
N/No = (1/2)^t/t1/2
N/No = (1/2)^115/55
N/No = (1/2)^2
N/No =1/4
Hence, the percentage = 1/4 * 100/1 = 25.0000%

20 * .10 = 2 <em>(2 = 10% of 20)</em>
20 + 2 = 22
20 x .07 = 1.4 <em>(1.4 = 7% of 20)</em>
20 + 1.4 = 21.4
The price of a 20$ haircut with a 10% tax would be $22.
The price of a 20$ haircut with a 7% tax would be $21.40.
I agree with with the florist because when you divide 207 by 10 you will get 20.7. This means that the florist could make 20 bouquets but seven flowers would be left out.
Hope this helps and please mark brainliest!
