Samuel was preparing for the triathlon. He did 3 activities every morning: Ran for 30 minutes, covering 4.5 miles. Swam for 20 minutes, covering 2/3 mi. biked for 45 min, covering 9 miles. What was Samuel's average speed during his morning training?
PLEASE HELP!!!
If Samuel ran for 30 minutes covering 4.5 miles, swim for 20 minutes covering 2/3 miles and biked for 45 min covering 9 miles, then the Samuel's average speed during his morning training is 0.15 miles per minute
The Morning activities of Samuel
He ran for 30 minutes, covering 4.5 miles,
He swim for 20 minutes covering 2/3 miles
He biked for 45 minutes covering 9 miles
Total distance travelled = 4.5+ 2/3 +9
= 14.17 miles
Total time taken = 30+20+45
= 95 minutes
The average speed = Total distance / Total time taken
= 14.17/95
= 0.15 miles per minutes
Hence, if Samuel ran for 30 minutes covering 4.5 miles, swim for 20 minutes covering 2/3 miles and biked for 45 min covering 9 miles, then the Samuel's average speed during his morning training is 0.15 miles per minute

What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Slope A = (0 - 2)/8 - 0)
Slope A = -2/8
Slope A = -1/4 or -0.25.
Note: The slope of any straight line also represents its rate of change.
Rate of change of Function A = -0.25.
Rate of change of Function B = 4.
Mathematically, the standard form of the equation of a straight line is given by;
y - y₁ = m(x - x₁)
At point (0, 2), we have:
y - 2 = -1/4(x - 0)
y - 2 = -x/4
y = -x/4 + 2.
Therefore, the intercept (initial value) of Function A is greater than the intercept (initial value) of Function B.

A motorboat travels 282 kilometers in 6 hours going upstream. It travels 402 kilometers going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
Let,
B = the speed of the boat in still water
S = the speed of the stream
Use the equation for distance.
Rate * Time = Distance
Upstream:
(B-S)6 = 282
Downstream:
(B+S)6 = 402
Simply first:
(B-S)6 = 282
(B-S) = 282/6
B-S=47
(B+S)6 = 402
(B+S) = 402/6
B+S=67
Solve by elimination. Add the two equations.
B-S=47
+ B+S=67
2B = 114
B = 114/2
B = 57 km/hr (the speed of the boat in still water)
Substitute this into either equation and solve for S.
B+S=67
57 + S = 67
S = 67 - 57
S = 10 km/hr (the speed of the stream)
6 is 15% of what number
In this case, we'll have to carry out several steps to find the solution.
Step 01:

the net decimal equivalent is found by multiplying the complement of the discounts together. what is the net decimal equivalent when a series of discount of 48% , 27%, and 12% is applied?
The net decimal equivalent is 0.48, 0.27, and 0.12 when a series of discounts of 48%, 27%, and 12% are applied respectively.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
By multiplying the complement of the discounts collectively, one can determine the net decimal equivalent which is given in the question.
To determine the net decimal equivalent when a series of discounts of 48%, 27%, and 12% is applied.
The value of compliment (%) = 1/100
As per the given condition, the required discounts would be as:
discount of 48% = 48/100 = 0.48
discount of 27% = 27/100 = 0.27
discount of 12% = 12/100 = 0.12
Therefore, the net decimal equivalent is 0.48, 0.27, and 0.12 when a series of discounts of 48%, 27%, and 12% are applied respectively.

For the first question, we have that out of a total distance of 8 miles, they:
Walk 3/8 of the distance.Run 5/8 of the distance.Hence the proportional relationships for the distances are given as follows:
Walked = 3/8 x Total Distance.Ran = 5/8 x Total Distance.For a total distance of 32 miles, the distances walked and ran are given as follows:
Walked: 3/8 x 32 = 3 x 4 = 12 miles = 12 laps.Ran: 5/8 x 32 = 5 x 4 = 20 miles = 20 laps.For the second question, we have that the table has to following the given ratios of the first row to the second row, with the third row being the sum of the first two rows, hence the third table is correct.

What is proportional relationship?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k. Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.

At your child's birth, you begin contributing monthly to a college fund. The fund pays an APR of 4.1% compounded monthly. You figure your child will need $30,000 at age 18 to begin college. What monthly deposit is required?
the monthly deposit that will be required will be equal to $ 1214 by compound interest.
We are given the information that:
Amount (A) = $ 30,000
Time = 18 years
Compound interest rate = 4.1 %
Now, let the principal amount be x.
So, by using the formula for compound interest, we get that:
30,000 = x ( 1+ 0.041)¹⁸
30,000 = x (1.041)¹⁸
30,000 = x × 2.06
x = 30,000 / 2.06
x = 14563 ( approx.)
Monthly deposit = 14563 / 12 = 1214 (approx.)
Therefore, the monthly deposit that will be required will be equal to $ 1214 by compound interest.

C. They are saving $350 by going with the more economical company.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For the cost functions in the context of this problem, we have that:
The slope represents the cost per shirt.The intercept represents the flat fee.Hence the functions for the cost of buying x shirts are given as follows:
Custom Ink: C(x) = 6.5x.Tees-4-U: T(x) = 250 + 5.5x.The costs will be the same when:
C(x) = T(x)
Hence:
6.5x = 250 + 5.5x
x = 250
For item b, the costs are given as follows:
C(250) = 6.5(600) = 3900.T(250) = 5.5(600) + 250 = 3550.The amount saved in item c is:
3900 - 3550 = 350.

The three numbers are
(Use a comma to separate answers as needed.)
First number (x) = 88
Second number (9x) = 792
Third number (x + 100) = 188
Let x be the first number, so accordingly the second number will be 9 times x i.e., 9x and the third number will be 100 more than the first number i.e., x + 100
Now, put all the numbers into an equation of finding their sum,
First no. + Second no. + Third no. = SUM, i.e.,
x + 9x + (x+100) = 1068
Simplify,
x + 9x + (x+100) = 1068
x + 9x + x +100 = 1068
11x + 100 = 1068
11x = 1068 - 100
