Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups

Answers

The correct answer is:

t ≥ 158.33, or rounded, t ≥ 160.

Explanation:

The equation we're given is 
W = -0.414t + 129.549, which an be written as
-0.414t + 129.549 = W.

We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.  Plugging this information in, we have:

-0.414t + 129.549 ≤ 64

To solve this, we first cancel 129.549 by subtracting from both sides:
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549

Now divide both sides by -0.414:
-0.414t/-0.414 ≤ -65.549/-0.414
t ≥ 158.33

(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)

5t-2r=25

solve for t.

Answers

Given 5t - 2r = 25

To solve for t,
first, we add 2r to both sides of the equation, to get

5t - 2r + 2r = 25 + 2r

5t = 25 + 2r

Next, we divide both sides of the equation by 5, to get

t= (25+2r)/(5)

Answer:

t= \frac{25+2r}{5}

Thompson's market sells a 25 pound bag of happy chow dog food for $15.49 and a 30 pound bag of super chow dog food for $17.39 which brand is the better buy?Explain

Answers

Answer:

The better buy would be super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Step-by-step explanation:

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Super chow is $17.39 for 30 pounds

The price per pound of Super chow=17.39/30=$0.58

Happy chows($0.62)>Super chow ($0.58)

The better buy would be Super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Caleb draws 14 dogs on each of 4 posters.He draws 18 cats on each of 6 other posters. If he draws 5 more dogs on each poster with dogs, how many dogs ad cats does he draws?

Answers

Caleb draws 14 dogs on each of 4 posters.
Then,
Number of dogs drawn by caleb in the first instance = (14 * 4) dogs
                                                                                    = 56 dogs
Celeb drew 18 cats on each of 6 other posters.
Then
Number of cats drawn by Caleb in the first instance = (18 * 6) cats
                                                                                   = 108 cats
Again Caleb draws 5 more dogs on each poster with dogs.
Then,
The number of Dogs drwn in the second instance = (5 * 4) dogs
                                                                                 = 20 dogs
So, the total number of dogs drawn by Caleb = ( 56 + 20) dogs
                                                                         = 76 dogs
Then the total number of cats and dogs drawn by Caleb = 108 + 76
                                                                                           = 184
