or, in decimal
-4.375
Step-by-step explanation:
[tex]\textrm{The expression is }\rm -1\frac{1}{2}-\left(+3\frac{1}{2}\right)-\left(-5/8\right)[/tex]
[tex]\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\\-1\dfrac{1}{2} = -\dfrac{1\cdot 2+1}{2} = -\dfrac{3}{2}\\\\\\+3\dfrac{1}{2} = +\dfrac{3\cdot 2+1}{2} = +\dfrac{7}{2} = \dfrac{7}{2}[/tex]
[tex]\textrm{The expression is }\rm -1\frac{1}{2}-\left(+3\frac{1}{2}\right)-\left(-5/8\right)\\= -\dfrac{3}{2}-\left(\dfrac{7}{2}\right)-\dfrac{-5}{8}\\\\\\= -\dfrac{3}{2}-\dfrac{7}{2}\right)+\dfrac{5}{8}\\\\\\[/tex]
The LCM of 2 and 8 is 8
Multiply each term by 8 and divide the result by 8
We get for numerator:
[tex]8\cdot\dfrac{-3}{2} - 8\cdot \dfrac{7}{2} + 8\cdot \dfrac{5}{8}\\\\= -12 - 28 + 5 = -35\\[/tex]
Denominator is 8
So answer is
[tex]\boldsymbol{-\dfrac{35}{8}}[/tex]
In decimal that would be -4.375

Charlie and Violet met for lunch at a restaurant between Memphis and New Orleans. Charlie had left Memphis and drove 5.5 hours towards New Orleans. Violet had left New Orleans and drove 2 hours towards Memphis, at a speed 10 miles per hour faster than Charlie's speed. The distance between Memphis and New Orleans is 395 miles. Find the speed, in miles per hour, of the two drivers.
Charlie 50 miles per hour
Violet 60 miles per hour
It is given that the distance between Memphis and New Orleans is 395 miles. This means, the total distance both covered = 395 miles
Charlie drove for 5.5 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour
Since, distance = speed × time
Distance covered by Charlie = 5.5x
Distance covered by Violet = 2(x + 10)
Altogether they covered 395 miles,
So,
395 = Distance covered by Charlie + Distance covered by Violet
395 = 5.5x + 2(x + 10)
395 = 5.5x + 2x + 20
375 = 7.5x
x = 375/7.5
x = 50 mph
Since, x represents the speed of Charlie, the speed of charlie was 50 miles per hour and speed of Violet =
Speed of Charlie +10
50+10 =60
speed of Violet =60mph

The number of people aged 31-50 years old are cell phone users in the tri-County area are 26,767,650.
What is defined as the pie chart?A pie chart, also known as a circle chart, is a method of summarizing a set of numeric variables or displaying the variables of a given factor (e.g. percentage distribution).
A circle is divided into segments in this type of chart. Each section represents a different category.A pie chart (also known as a circle chart) is a radial statistical graphic that is divided in to other slices to show numerical proportion. The arc length of each slice in a pie chart (and thus its central angle but also area) is proportional to the amount it represents.For the given question;
The total population = 72,345,000.
The total percentage between 31-50 years old = 23% + 14% (see from graph).
Let x be the total number of people between aged between 31 -50 years who are cell phone users.
(23% + 14%) of 72,345,000 = x
x = 37× 72,345,000 / 100

Divide 2 5/16 ÷ 7/8
helpppppppppp
Answer:
When dividing fractions we "invert and multiply".
First, we should change 2 (5/16) to 37/16.
So, 37 / 16 divided by 7 / 8 equals
37 / 16 times 8 / 7
which equals 296 / 112 = 37 / 14 which equals
2 (9/14)
Step-by-step explanation:
Determine the range of f(x) = |x + 5|.
{y | −∞ < y < ∞}
{y | −5 < y < ∞}
{y | 0 ≤ y < ∞}
{y | 5 ≤ y < ∞}
The range for the given function f(x) = | x + 5 | is {y | 0 ≤ y < ∞}
What is a function?A function defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The independent variable = domain
The dependent variable = Range
We have a function,
f(x) = | x + 5 |
Let,
f(x) = y
x = -7, y = | -7 + 5 | = | -2 | = 2
x = -5, y = | -5 + 5 | = 0
x = -6, y = | -6 + 5 | = | -1 | = 1
x = -4, y = | -4 + 5 | = 1
x = -3, y = | -3 + 5 | = 2
x = -2, y = | -2 + 5 | = 3
x = -1, y = | -1 + 5 | = 4
x = 0, y = | 0 + 5 | = | 5 | = 5
x = 1, y = | 1 + 5 | = | 6 | = 6
x = 2, y = | 2 + 5 | = | 7 | = 7
x = 3, y = | 3 + 5 | = | 8 | = 8
..
..
..
We see that as x takes any value y increases.
x = domain, and y = range
y = 0, 1, 2, 3, 4, 5, ,,,,,,,∞
Thus the range is {y | 0 ≤ y < ∞}

A billboard painter is using a pulley system to hoist a can of paint up to a scaffold at a rate of half a meter per second. The height of the can of paint as a function of time is given by h(t) = 0.5t + 8. Five seconds after he starts raising the can of paint, his partner accidentally kicks a paint brush off of the scaffolding, which falls to the ground. The height of the falling paint brush can be represented by h(t) = −4.9(t − 5)2 + 38. When does the brush pass the paint can? If necessary, round your answer to the nearest hundredth.

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
The equations are:
h(t) = 0.5t + 8.
h(t) = −4.9(t − 5) + 38.
Then
= 0.5t + 8

And
= 0.5t + 8
= −4.9t + 24.5 + 38.
And
= 0.5t + 8
= −4.9t + 62.5
Now,
Subtact the equations then
= 0.5t + 8 - (−4.9t + 62.5)
= 0.5t + 8 + 4.9t - 62.5
= 0.5t + 4.9t - 62.5+8
= 5.4t -54.5

Find the value of r so the line that passes through each pair of points has the given slope.
(r, 7), (3, 4), m = -3/5
The value of r so that the line passes through (r, 7), (3, 4) and slope of - 3 / 5 is - 2.
How to find the pair of point of a line using the slope?The slope of the line is given as m = - 3 / 5.
The pair of point are (r, 7)(3, 4).
Using slope intercept form equation is as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, using (3, 4) we will find the y-intercept
y = - 3 / 5 x + b
4 = -3 / 5 (3) + b
4 = - 9 / 5 + b
b = 4 + 9 / 5
b = 20 + 9/ 5
b = 29 / 5
Therefore, the equation of the line is as follows;
y = - 3 / 5x + 29 / 5
Hence, let's find r (r, 7)
7 = -3 / 5(r) + 29 / 5
7 - 29 / 5 = -3 / 5 r
35 - 29/ 5 = -3 / 5 r
6 / 5 = - 3 / 5 r
cross multiply
-15r = 30
divide both sides by -15
r = 30 / -15
r = -2
Therefore, the value of r is -2.

a desk is on sale for $380, which is 40% off the original price. which equation can be used to determine the amount of money saved, s, in dollars, when purchasing this desk on sale?
you save $253.33 if you purchase this desk on sale.
How to find the money saved?
We know that the price in sale of the desk is $380, and this is given by a discount of the 40% of the original price.
So, if the original price is defined by the variable P, the amoun you save by buying the discounted deck is:
P - $380
Now, remember that the discounted price should be written in terms of P as:
$380 = P*(1 - 0.4) = P*0.6
Where 0.4 is the decimal form of 40%.
With that we can find the value of P as:
P = $380/0.6
Then the amount that you save is given by:
P - $380 = $380/0.6 - $380 = $253.33

Finx, inc, purchased a truck for $40,000. The truck is expected to be driven 15,000 miles per year over a five-year period and then sold for approximately$5000.
Determine depreciation for the first year of the trucks useful life by the street wine in units of output methods if the truck is actually driven 16,000 miles.
Round to two decimal places.
The depreciation for the first year of the truck's useful life is $32,000.
The cost of the truck is $40000.
The useful time is 5 years.
The residual value is $5000.
Now, the depreciation is given as:
SLM depreciation = (Cost - Residual Value) / 5 years
Depreciation expense per year = ($40,000 - $5,000) / 5
Depreciation expense for the first year = $7,000
Now,
The depreciation expense per mile is the difference between cost and residual value divided by expected miles over the truck's life.
Depreciation expense per mile = (Cost - Residual Value) / Expected miles over truck's life.
Depreciation expense = Depreciation expense per mile × Miles driven
Therefore,
Depreciation expense per mile will be:

What is a parallelogram ?
A parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees.
The figure shown is an parallelogram, where length of opposite sides are equal to each other
From the figure,
x = 7, as opposite side of x is given as 7
x + y = 18,
Putting the value of x in the above equation,
7 + y = 18
y = 18 - 7
y = 11
Therefore, we get after solving the given equations :
x = 7
y = 11
