Kim learned in her science class that every 2 minutes she spends in the shower, she uses 17 gallons of water. This rate is constant
The rate of using water per minute will be 8.5 gallons per minute.
What is the rate of flow?The rate of flow of water is defined as the amount of water or any liquid flowing in a unit of time. If the gallons of water are flowing in some minutes the rate will be measured in the gallons of water.
Given that Kim learned in her science class that every 2 minutes she spends in the shower, she uses 17 gallons of water.
The rate of flow of water will be calculated as:-
Rate of flow = Volume of water / Time
Rate of flow = 17 / 2
Rate of flow = 8.5 gallons per minute
Therefore, the rate of using water per minute will be 8.5 gallons per minute.

How is volume calculated given mass and density?
Sum of mass and density
Mass divided by density
Mass multiplied by density
Difference of mass and density
Answer:
B.
Step-by-step explanation:
when trying to calculate the volume when being given the M or the mass, and the D or density, hears is the calculations needed for that: P=M/V, which also means volume is the mass divided by the volume, or density. Hence, the answer would be mass divided by density. hope this helps!!! (also, please give me brainliest.)
Volume is calculated given mass and density is Mass divided by density.
What is volume?
Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic meter and liter) or by various imperial units (such as the gallon, quart, cubic inch).
Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration (change of velocity) when a net force is applied.
Density is defined as a measure of how compact the mass in a substance or object is.
Since, density of a substance is measure as the ratio of its mass to its volume,
Density = Mass/Volume
or, Density x volume = mass
or, Volume = Mass/Density
Hence,Volume is calculated given mass and density is Mass divided by density.

Samuel recorded the number of different types of pets his friends have in the table shown below: Cats 5 Dogs 3 Rabbits 1 Guinea Pigs 3
Answer:
Samuel's friends have a total of 12 pets.
Explanation:
To find the total number of pets Samuel's friends have, we simply add up the number of each type of pet:
Number of Cats: 5
Number of Dogs: 3
Number of Rabbits: 1
Number of Guinea Pigs: 3
Total number of pets = 5 (cats) + 3 (dogs) + 1 (rabbits) + 3 (guinea pigs) = 12
So, Samuel's friends have a total of 12 pets.

Find the value of k
given that the line through (−1, k)
and (−7,−2)
is parallel to the line y = x+1
.
Given two lines are parallel, their slopes are equal. After calculating the slopes of the two lines and solving the equation, we find that the value of 'k' in the question is 4.
Explanation:In the realm of Mathematics, when two lines are parallel, their slopes are equal. The line y = x + 1 has a slope of 1. To find the slope of the line through (−7,−2) and (−1, k), use the formula for slope, which is m = (y2 - y1) / (x2 - x1). Here, (x1,y1) is (−7,−2) and (x2,y2) is (−1, k). Hence, the equation for slope would look like this: m = (k - (-2)) / (-1 - (-7)).
As the slopes are equal, we can form an equation 1 = (k + 2) / 6. Solving this equation will give us the value of k. By multiplying both sides by 6, we obtain 6 = k + 2. Consequently, subtracting 2 from both sides, we get k = 4.

Share the advantages and disadvantages of the different methods for solving quadratic equations that you have learned. Share special techniques that you have developed along the way. For example, explain to your classmates your technique for remembering the quadratic formula (song, rhyme, rhythm, etc.) to help others remember it as well.
The factors of a quadratic equation will be (qx + r) and (sx+t). If the solutions are all integers, you may be able to quickly find q, r, s and t. The advantage of this method is that factoring can be very fast. The disadvantage is that factoring may not work; for instance, factoring will not find solutions that are not integers.
Completing the SquareCompleting the square is a multistep process. The main idea is to convert the original equation into one of the form (x + a)^2 = b, where a and b are constants. The advantage of this method are that it always works and that completing the square gives some insight into how algebra works more generally. The disadvantage is that this method is complex.
Quadratic FormulaThe quadratic formula is x = (-b +- (b*2 - 4ac)^.5))/2a. The advantages of this method are that the quadratic formula always works and is straightforward. The disadvantages are that the formula provides no insight and can become a rote technique.
GuessingSometimes, you can guess an approximate solution. Then, you can increase or decrease your guess, depending on whether the result from your first guess is too big or too small. The advantages of this method are that guessing can be very fast if you guess right, and can get an approximate answer quickly, if that is all you need. The disadvantage is that sometimes you won't be able to make a good guess .

Solve the inequality
-8x - 10 > 7x + 20
A.) x < - 30
B.) x > - 2
C.) x > - 30
D.) x < - 2
To solve the inequality -8x - 10 > 7x + 20, combine like terms, isolate the variable term, and solve for x. The correct answer is D) x < -2.
Explanation:We need to solve the inequality -8x - 10 > 7x + 20.
First, let's combine like terms by adding 8x to both sides. This gives us -10 > 15x + 20. Next, subtract 20 from both sides to isolate the variable term. This gives us -30 > 15x. Finally, divide both sides by 15 to solve for x. This gives us x < -2.Therefore, option D.) x < -2 is the correct answer.
