<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.
Out of 300 students, 26% would prefer long jump, hence the amount is given by:

Answer:
68
Step-by-step explanation:
Lets first find the quantity of tape the computing center is purchasing/month.
3/5 Of their 1600 dollar spending is on the heavy duty tapes, meaning they are spending 960 dollars/month on heavy duty tape, if we divide that by the original price, 40, it will give us the original quantity of heavy tape they are purchasing, 24/month.
The other 2/5 of their money, 640 dollars, are spent on regular tape, meaning they purchase 20 rolls of regular tape/month.
Given they are purchasing 24 rolls of heavy tape and 20 rolls of regular tape every month, we can simply multiple those by the new prices and sum the results.
24*38=912
20*31=620
912+620=1532
Then to find the money they are saving we subtract the new price from the original price.
1600-1532=68
I'm thinking it's a parabola since you can cover a vast amount of apace within the parabola too.

Answer:
The numbers will be "11 and 12".
i believe
Step-by-step explanation:
x(x + 1) > x + x + 1 + 109 where x and x+1 are the 2 numbers.
x^2 + x > 2x + 110
x^2 - x - 110 > 0
(x - 11)(x + 10) > 0 The critical values are 11 and -10 but number must be natural
So the value of x is 11
The numbers are 11 and 12
