Answer:
a. L.B. = 20.5
b. U.B. = 21.5
Step-by-step explanation:
Length is measured 21 cm correct to 2 significant figures
a. Lower bound of 21
= 20.5 < 21
= 20.5
b. Upper bound of 21
= 21 < 21.5
= 21.5

Answer:
a68 = -85.2
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =8.6 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
7.2-8.6 =-1.4
d=-1.4
n = the term number we are looking for
an = 8.6 -1.4(n-1)
We are looking for the 68th term so n=68
a68 = 8.6 -1.4(68-1)
= 8.6 -.1.4(67)
= 8.6-93.8
=-85.2
Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=
∴The percent of salt in solution
Therefore, He made 110 kilograms of 9.09% salt solution.
