John swims 5/12 of a mile in 3/8 of an hour what distance in miles does John swim in an hour
Answer:
1.1 mph
Step-by-step explanation:
Step one:
John swims a distance of 5/12 miles
time taken = 3/8 of an hour
Required
The speed with which John swims
Step two:
speed= distance/time
substituting we have
speed= 5/12/3/8
multiply the numerator by the inverse of the denominator
speed= 5/12*8/3
speed= 40/36
speed= 1.1 mph

2. Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation.
y = 4.5 when x = 3
a. k = 13.5; xy = 13.5
b. k = 1.5; y = 1.5
x
c. k = 1.5; y = 1.5x
d. k = 13,5; 13.5y = x
Answer:
Correct choice: a. k = 13.5; xy = 13.5
Step-by-step explanation:
Inverse Proportion
Two variables x and y are in inverse proportion or variation if:
[tex]\displaystyle y=\frac{k}{x}[/tex]
Where k is the constant of proportionality
Since we know that y=4.5 when x=3:
[tex]\displaystyle 4.5=\frac{k}{3}[/tex]
Solving for k:
[tex]k = 4.5*3 = 13.5[/tex]
Thus the equation is:
[tex]\displaystyle y=\frac{13.5}{x}[/tex]
Or, equivalently:
[tex]xy = 13.5[/tex]
Correct choice: a. k = 13.5; xy = 13.5

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has the best popcorn. In this case, the "best" popcorn is the most buttery! In your quest to find the best, you meet with each theatre manager individually and ask for the ratio of oil to popcorn kernels that they use in their recipes. Here are their responses. The manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight. The manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week. The manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday. Find the ratio value of oil to popcorn kernels for Theatre A. Type your answer as a number. Theatre A's recipe calls for cup oil for every cup of popcorn kernels.
Answer:
C is 6 / 32 = 3 / 16.
Step-by-step explanation:
Maya adds 6 grams of sugar to a bottle containing 14 grams of warm water. What is the total weight of the sugar and water?
Answer:
The total weight of the sugar and water is 20 grams
Step-by-step explanation:
Given;
weight of sugar Maya added, w₁ = 6 grams
weight of water contained in the bottle, w₂ = 14 grams
The total weight of the sugar and water = 6 grams + 14 grams
The total weight of the sugar and water = 20 grams
Therefore, the total weight of the sugar and water in the bottle is 20 grams.

write down the first 4 terms in the expansion of (1+2x)^7
Answer:
1 + 14x + 84x^2 + 280x^3 or
128x^7 + 448x^6 + 672x^5 + 560x^4.
(see explanation),
Step-by-step explanation:
They are 1^7 + 7C1 1^(7-1)(2x) + 7C2 1^5 (2x)^2 + 7C3 1^4 (2x)^3
= 1 + 14x + 21* 4x^2 + 35*8x^3
= 1 + 14x + 84x^2 + 280x^3
If you require the answer in descending degrees of x by a similar method the answer is:
128x^7 + 448x^6 + 672x^5 + 560x^4.

the slope of the given line is:
Explaining the Concept:
We need to find the slope of the given line:
We know that Slope of a line = Rise/Run. So, to calculate the rise and the run, we will use the points (0,4) and (2,0) on the line
Finding the Slope:
Rise:
We know that the rise of a line is its change in y-coordinate
So, rise of the given line = y₂ - y₁
Rise = 0 - 4 [Since y₁ = 4 and y₂ = 0]
Rise = -4
Run:
We know that the run of a line is its change in x-coordinate
So, Run = x₂ - x₁
Run = 2 - 0 [Since x₁= 0 and x₂ = 2]
Run = 2
Slope:
As we said before,
Slope = Rise/Run
replacing the variables
Slope = -4/2
Slope = -2
Hence, the slope of the given line is -2

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.

if a quadratic equation has 4-i as a solution, what must the other solution be?
Answer:
4+i
Step-by-step explanation:
A complex number usually took the form a+bi where a and b are real numbers and 'i' represents an imaginary number. For a quadratic equation, the complex roots for the root of a quadratic equation took the form known as complex conjugates. The complex conjugates are formed by changing the sign of the imaginary part.
SO, if a quadratic equation has 4-i as a solution, the other solution must be 4+i.
