Answer:
Number of jars filled is 3 
(approximately 4).
Step-by-step explanation:
Initial amount of salt = 1/2 cup.
Amount of salt left = 1/9 cup.
Amount of salt used = 1/2 - 1/9
= 
= 7/18
The size of each jar = 1/10 cup.
Amount of salt used = size of the each jar x number of jars filled
7/18 = 1/10 x number of jars filled
number of jars filled = 7/18 ÷ 1/10
= 7/18 x 10/1
= 70/18
= 3
= 3.9
The number of jars filled is approximately 4.
Given:
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair 
is in the function 
, then 
.
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
Therefore, the value of f(2) is 3 and the value of f(5) is 6.
Answer:
The answer to your question is:
x = 18
m∠ABD = 36°
m∠DBC = 54°
Step-by-step explanation:
m∠ABD + m∠DBC = 90°
2x + 3x = 90°
5x = 90°
x = 90/5
x = 18
m∠ABD = 2(18)
= 36°
m∠DBC = 3(18)
= 54°
