What is the youngest age Warren can be?

Answers

Answer 1
Answer:

m - Marty's age

w - Warren's age

Marty is 3 years younger than 6 times his friend Warren's age.

6 times his friend Warren's age ----- 6w

Marty is 3 years younger than 6 times his friend Warren's age.  

(1)     m = 6w - 3  

(2)    m + w > 11  

Substitute (1) into (2).

6w - 3 + w > 11

7w > 14

w > 2

Warren can be as young as 3 years old.

Answers

1. If I remember from class correctly, your monthly expenses should be about 20% of your net income, so the answer would be D. Although, adding up the expenses would work as well.
2. If the payment is bi-weekly, and there are 4 weeks in a month, you only have to multiply by 2, because "bi-weekly" means every 2 weeks, which means the payment would come twice a month. So, the answer would be A, Multiply by 2 and then round.
3. Round each of the numbers. 978 becomes 980, 54.89 becomes 55, and 93 becomes 90. We'll assume that there are 4 weeks in a month. Add them all up. 980+55+90+90+90+90 = 1395  So, yes, your answer of D, 1,400.00 is a good estimate.
4. Again, round each of the numbers. 455 can stay the same, 34.95 becomes 35, 65.88 can stay at 65 for the sake of easy math, and 87 gets rounded up to 90.
We'll keep assuming that there are 4 weeks in a month. Now, add them all up. Be sure to remember that the rent is bi-weekly, so it has to be added in twice. 455+455+35+65+90+90+90+90 = 1370. This means that of the choices, D, 1,359.00 is a good estimate of the monthly expenses.

How many liters of water should be added to 18 liters of a 14% bleach solution so that the remaining solution contains only 10% bleach?

Answers

How many liters of water should be added to 18 liters of a 14% bleach solution so that the remaining solution contains only 10% bleach?
:
Let w = amt of water required to make a 10% solution
:
.14(18) = .10(w+18)

2.52 = .1w + 1.8
2.52 - 1.8 = .1w
.72 = .1w
multiply both sides by 10
7.2 = w
:
7.2 liters of water added

In 1906 Americans consumed an average of 26.85 gallons of whole milk per year. By 1998 the average consumption was 8.32 gallons. What is the percent decrease in consumption of whole milk?

Answers

Answer: 69.01%

Step-by-step explanation:

In 1906 Americans consumed an average of 26.85 gallons of milk per year while by 1998 the average consumption was 8.32 gallons.

To get the percent decrease in consumption of whole milk goes thus:

We first find the amount of decrease in the milk consumed. This will be:

= 26.85 - 8.32

= 18.53

Percentage decrease

= 18.53/26.85 × 100

= 0.6901 × 100

= 69.01%
