Ms. Arvelo’s dog weighs too much! The vet says that he needs to be 50 pounds. He currently is 70 pounds. The vet wants him to lose weight in the next 4 weeks. Create an equation to determine the number of pounds, p, that Ms. Arvelo’s dog has to lose per week.
Answer:
5 pounds per week
Step-by-step explanation:
70 - 50 = 20 meaning he has to lose 20 pounds in 4 weeks so divide 20 by 4 you get 5 pounds per week.

1.What happens when fertilizer ends up in waterways?
2. Describe eutrophication.
3. What has happened at the mouth of the Mississippi River?
Answer:
1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.
2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)
3. I don't know I am way to tired sorry
Step-by-step explanation:
1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.
2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

1. "The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age. Nixon's first presidential election happened 39 years after the Great Depression. Using the given information, write an equation to find Raul's age, r."
2. "Rewrite the equation from part A by factoring the side that contains the variable r."
3. "Solve the two previous equations for r. What value does each equation give for Raul's age. Are the two values the same?"
4. "Raul's grandfather is Miguel, and Raul's sister is Paula. Raul's age is the same as his grandfather's age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from question 2, write an equation to find Paula's age, p, in years."
5. "Rewrite the equation from question 4 by factoring the side that contains the varible p."
6. "Solve the equation for p to find Paula's age. Express her age in years as a fraction."
7. "How many months old is Paula?"
Answer:
Answer:
Raul's age is 15 years.
Step-by-step explanation:
r represents Raul's age.
The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.
The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.
Therefore, 3r - 6 = 39
Add 6 to both sides.
3r = 45
Divide both sides by 3.
r = 15
Hence, Raul's age is 15 years.
Combine like terms and simplify 4r - 6 - 2r + 5
A. 2r - 1
B. 10r + 5
C. 10r - 3
D. 2r + 1
A right triangle has a hypotenuse of length 13 in. and a leg with length 4 in. What is the length of the other leg?
Answer:
Solution,
Let the hypotenuse of the right triangle be 'a' and its legs be 'b' and 'c'.
Here, a= 13, b = 4 and c=?
Using Pythagoras or Gogou theorem,
a² = b² +c²
or, 13² = 4² +c²
or, c² =153
or, c = 3√17 inch

Which situation would require determining volume?
A Nick wants to know how much tile it takes to cover the floor of a room.
B Sarah wants to know how much water her fish tank can hold.
C Min wants to know how much fence is needed to go around the edges of his yard.
D Kiki wants to know how wide her window is.
Answer:
b
Step-by-step explanation:
because volume is like filling and 3d everything else is area and perimeter
Out of all the situations described, the only one where volume would need to be determined is B Sarah wants to know how much water her fish tank can hold.
When it comes to any measurement involving how much water is needed for something, volume is always the best measurement because water is measured in volume. Sarah's situation is therefore the situation that requires volume.
The other options are wrong because:
Knowing how much tile to use requires area Knowing how much fence will go around a year requires perimeter Knowing how wide a window is requires measuring the width of the windowIn conclusion, Sarah needs to determine volume to know how much water the tank can hold.

Answer:
the ratio is 18:81
Step-by-step explanation:
Okay so when a question is asking for a ratio it is basically asking a number compared to another:
So if you had 14 green frosted cupcakes and 8 blue frosted cupcakes what is the ratio of total frosted cupcakes to blue cupcakes:
the answer would be 22:8
Because you are trying to compare the total number of cupcakes to the blue cupcakes.
So back to your equation it wants to know the ratio between empty spots and the total number of parking spaces
Since we know that 63 of the spots have cars and 18 spots are empty we are going to add 63 and 18 together to get the total amount of parking spaces:
18 + 63 = 81
And since they want to know the empty spots compared to the total number of parking spaces we are going to be putting 18:81.
Hope this helped you!!!

Answer:
A is 23x+2=94
B is 4
C is 20.5 by 26.5
Step-by-step explanation:
To solve get the equation, you have to combine the two equations, which gets you 5.5x -1.5 + 6x +2.5
Then you combine like-terms, which is 5.5x+6x and -1.5 +2.5 and that equals 11.5x + 1 and then multiply that by 2 {2(11.5x +1) } and you should get
23x+2 and then put the 94 at the end (23x + 2 = 94). Then just solve the equation and you get the rest of the answers.
