Answer:
Percentage increase in the height is 55%.
Step-by-step explanation:
Since Cindy is growing plants for a science project. During the project Cindy found that one plant grows from 7 cm to 10.85 cm.
We have calculate percent increase in the height of the plant.
We know formula to calculate the percentage is
% Increase in the height = Net increase in the height×100/Initial length of the plant
= 
Therefore % increase in the height of the plant is 55%.
Step-by-step explanation:
everything can be found in the picture
Answer:
<em>20%</em>
Step-by-step explanation:
<em>First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.</em>
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
Further explanation:
Let x be the price of one citron and
y be the price of one fragrant
Then according to given statement
10x+7y = 55 Eqn 1
7x+10y = 64 Eqn 2
Multiplying equation 1 by 7

This will be equation 3.
Multiplying equation 2 by 10

This will be equation 4.
Subtracting equation 3 from equation 4

So,
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
