Area of the label is calculated as diameter*PI*height
So if height of tomato can is 3 times the can of tuna: hTOM=3*hTUNA
Diameter of a tomato can is three times smaller so: dTOM=dTUNA÷3
so Area of a tomato can label= A=(dTUNA÷3)*PI*3*hTUNA
A=dTUNA*PI*hTUNA
and the area of a tuna can label=
A=dTUNA*PI*hTUNA
So, the label areas are the same.
28% decrease
Solution:
Calculate percentage change
from V1 = 25 to V2 = 18
(V2−V1)|V1|×100
=(18−25)|25|×100
=−725×100
=−0.28×100
=−28%change
=28%decrease
In order to achieve an average of 12 successful shots she has to score 36 times in total. So, she has to score 5 times in the 3rd set.
13 + 18 + 5 = 36
In order to achieve an average of 16 successful shots she has to score 48 times in total. So, she has to score 17 times in the 3rd set.
13 + 18 + 17 = 48
Express your answer in the form of a compound inequality using the variable F to represent a successful basketball free throw:
5 <= F <= 17
<em>use √(ab) = √a · √b</em>
<em>use (a + b)(a - b) = a² - b²</em>
<em>use √a · √a = a and √(ab) = √a · √b</em>
