In mixed fraction the total distance of the fun run is 11 1/14
A school is organising a fun run. The fun run involves a 5 1/2
mile run around the field, then a 5 4/7 mile run back to the school.
The total distance is equal to summation of run around the field and run back to school.
total distance = 5 1/2 + 5 4/7
= 11/2 + 39/7
The L. C. M of 2 and 7 is 14
= [tex]\frac{11.7}{2.7} + \frac{39.2}{7.2}[/tex]
(77 + 78)/14
155/14
Upon dividing 155 by 14, the quotient is 11 and the the remainder is 1
In mixed fraction it is 11 1/14
So in mixed fraction the total distance of the fun run is 11 1/14

D) The athlete was paid $213,917.52 per hour.
A) Assume a basketball player received $20,750,000 for playing 80 games, each lasting 48 minutes.
X = 20,750,000 ÷ 80

B) Assuming the athlete played every minute of every game.
X = 259375 ÷ 48
X = 5403.64
C) On the other hand, suppose the athlete performed in two-thirds of the games.
X = 259375 ÷ (48 x 2 ÷ 3)
X = 259375 ÷ 32
X = 8105.46
D) Finally, suppose that over one year, the athlete practiced or practiced 33 hours for each game and afterward played every moment of that time.
X = 20,750,000 ÷ (33 + (48 x 80 ÷ 60)

How to simplify an expression?An expression is simplified combining the like terms, that is, adding or subtracting, depending on the signal, the terms that have the same variable and the same exponent.
For item 1, the variables are common for all terms, hence we just add the terms keeping the variable, hence:
4g + 6g + g = 11g.4m - m = 3m.5k² - 4k² - 2k² = -k².For item 2, there are multiple variables, hence we combine the terms of each variable(we cannot add terms with x and y, for example), as follows:
5x + 3x + 5y + 6y = 8x + 11y.2a + 4b + 6c - 3b - 8c = 2a + b - 2c.Item 3 works similarly to item 2, as there are multiple variables, hence we combine the terms with each variable(or with the constant = no variable), as follows:
9q - 4q + 15 - 8 = 5q + 7.8r + 2s + 4t - 2r + s + 3t = 6r + 3s + 7t.What is the missing information?The questions are missing and are given by the image at the end of the answer.

What is Slope?
A slope of a line is a number that describes both the direction and the steepness of the line.
Given that;
Two points on line are (0, 5) and (-12, 2).
Now, The slope of the line passing through (0, 5) and (-12, 2) are calculated as;
m = (2 - 5)/ (-12 - 0)
m = - 3 / -12
m = 3 / 12
m = 1/4
Thus, The slope of the line passing through (0, 5) and (-12, 2) will be 1/4.

Find out the slope AB
m=(2-0)/(3-2)

Remember that
If two lines are perpendicular, then, their slopes are negative reciprocal
so
the slope of the altitude that passes through C is -1/2
Find out the equation of the altitude that passes through C

Susan is painting her living room. Two of the walls are 10.75 feet long and 7 feet tall, and two of the walls are 6.875 feet long and 7 feet tall. If half a gallon of paint covers 200 square feet, how much paint will Susan need?
Answer:
2.63903744 gallons of paintStep-by-step explanation:
Check image below for explanation
If .5 gallon covers 200
and Susan needs 246.75
1 whole gallons covers 400 (too much)
.5 gallon = 200 paint
?? gallon = 46.75 paint
200 / 46.75 = 4.27807487
.5 / 4.27807487 = 2.13903744
2.13903744 gallon = 46.75 paint
So,
.5 gallon+ 2.13903744 gallon = 2.63903744 gallons
(200 paint + 46.75 paint = 246.75 paint)
2.6 gallons (rounded)

Given f of x is equal to the quantity x plus 3 end quantity over the quantity x squared minus 4 times x minus 21 end quantity and g(x) = log4x, evaluate (g – f)(8).
The numeric value of the subtraction function at x = 8 is given by:
(g - f)(8) = 0.5.
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the input variable in the function by the desired value.
To find the subtraction function, we find the numeric value of each function, then subtract them, as follows:
(g - f)(8) = g(8) - f(8).
Function f(x) is defined as follows:
f(x) = (x + 3)/(x² - 4x - 21).
At x = 8, the numeric value is given as follows:
f(8) = (8 + 3)/(8² - 4(8) - 21) = 11/11 = 1.
Function g(x) is defined as follows:
g(x) = log4(x).
At x = 8, the numeric value is given as follows:
g(8) = log4(8) = 1.5, as 4^(1.5) = 8.
Hence the numeric value of the subtraction function is given by:
(g - f)(8) = g(8) - f(8) = 1.5 - 1 = 0.5.

The patient's systolic blood pressure will be lowered by 48.709< m<56.091 at a 98% confidence interval.
What is a confidence interval?
For an unknown parameter, a confidence interval is just a range of guess. Usually 95% confidence level is generally the most usual, but other levels, such 90% or 99%, are occasionally used to generate a Confidence interval.The reduction in systolic blood pressure is, mean, x=52.4
Sample size, n=25
Standard deviation, s=8.5
We must determine the t value for a 90% Confidence interval because the sigma is unknown.
From Inverse t Distribution Calculator, the Confidence interval is 0.98 and the degree of freedom is 25-1=24:
One-sided t-Score: 2.1715
We can now determine the standard error E:
E=2.1715(8.5/√25)=3.691
We can now create the confidence interval by:
x - E < m < x+ E
52.4-3.691< m<52.4+3.691
