Answer:
......Im pretty sure its -4
Answer:
4550m ; 4
Step-by-step explanation:
Recall
1 hectometre = 100m
1 decameter = 10m
Distance from shore to center of island = 37hm
Another 85 decameter toward stge se direction
Therefore total metres it will travel in other to get to the treasure :
37 hectometre + 85 decameter
(37 * 100)m + (85 * 10)m
3700m + 850m = 4550m
In kilometers :
1000 meters = 1 kilometers
4550 meters =
(4550 / 1000)meters
= 4.55km
Using proportions, it is found that the correct amount to administer of CC would be of:
A. 0.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 500 mg are equivalent to one cc. How many cc are equivalent to 250 mg? Hence the <em>rule of three</em> is given by:
500 mg - 1 cc
250 mg - x cc
Applying cross multiplication:
500x = 250
c = 0.5.
Hence option A is correct.

The percent increase is 25 %
<em><u>Solution:</u></em>
Given that we have to find the percent incraese
From 24 teachers to 30
The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.
<em><u>The percent increase is given as:</u></em>
Here, initial value = 24 and final value = 30
<em><u>Substituting the values in above formula, we get</u></em>
Thus percent increase is 25 %
