A number, x, rounded to 1 decimal place is 12.3
Write down the error interval for x.
Answers
The error of interval for x will be [12.25, 12.35) for rounding off to 12.3 to 1 decimal place
In the given question, a number supposed to be 'x' is rounded off to the 1 decimal place, so that the number rounded off becomes 12.3. So, it is given that the number x is rounded off to 12.3 by 1 decimal place.
From this, we get that x should be greater than or equal to 12.25 and x should be smaller than 12.35. The equations will be :
=> x ≥ 12.25 and x < 12.35
So, the x lies between 12.25 and 12.35 which defines the error of interval for x.
Hence, the error of interval for x will be [12.25, 12.35)

In 2008, the number of digital cameras shipped totaled 186 million. There were 24 million shipped in 2013. Find and
interpret the average rate of change in the number of digital cameras shipped per year.
Answers
Step-by-step explanation:
the average change rate for a function g(x) is defined for an interval of x values as
(g(interval end) - g(interval begin))/(interval end - interval begin)
in our case that is
(g(2013) - g(2008))/(2013 - 2008) =
= (24 mil. - 186 mil)/5 = -162 mil./5 =
= -162,000,000 / 5 = -32,400,000
that means that as a mean value there were 32,400,000 digital cameras shipped less every year.
in other words, fewer and fewer digital cameras are sold. the demand is strongly declining.
actually, following the mean values and their trend, there should have been no new digital cameras shipped in 2014 anymore (as 24 mil. - 32.4 mil is less than 0).

Part b: Using the relationship given in the problem statement, write an equation for L in terms of W .
Solve the equations from parts a and b.

O Cannot be determined, because taxes and deductions are not provided
Answers
The gross income will be $5,800.
It is given that per month salary of an individual is $4000 and from a side job he makes $20 per hour for 10 hours a week for 4 weeks and rent he got is $1000.
We have to calculate the gross income.
What do you mean by gross income ?
Gross income refers to the total income of a person or business from all resources.
As per the question ;
Per month salary = $4000
Earning from side job is given $20 per hour for 10 hours a week for 4 weeks.
i.e.,
= 20 × 10 × 4
= $800 for 4 week
and
the rent they receive = $1000
So ;
The gross income will be ;
= 4000 + 800 + 1000
= $5,800
Thus , the gross income will be $5,800.

A local museum charges $25 per adult and $12 per child for admission fees. At the end of a day, the museum made $9,014 in total admission revenue, not including sales tax, and had a total of 450 guests.
The system of equations below can be used to model the number of guests that were children, x, and the number of guests that were adults, y.
First, place a point on the graph representing the solution to the system of equations. Notice that one of the equations in the system has already been graphed.
Then, determine the approximate number of guests that were children and the approximate number of guests that were adults for that day.
Answers
The approximate number of guests that were children are 172 and adults are 278
How to determine the approximate number of guests that were children and adults for that day?From the complete question, we have the following system of equations
25x + 12y = 9014
x + y = 450
Make y the subject in x + y = 450
y = 450 -x
Substitute y = 450 - x in 25x + 12y = 9014
25x + 12(450 - x) = 9014
Expand the expression
25x + 5400 - 12x = 9014
Evaluate the like terms
13x = 3614
Divide both sides by 12
x = 278
Substitute x = 278 in y = 450 -x
y = 450 - 278
Evaluate
y = 172
Hence, the approximate number of guests that were children are 172 and adults are 278

two angles are complementary. The measure of the larger angle is 6 degrees less than 3 times the measure of the smaller angle. The measure of the smaller angle is _______ degrees and the measure of the larger angle is______ degrees
Answers
Step-by-step explanation:
complementary means together they are 90°.
x = 3y - 6
x + y = 90
(3y - 6) + y = 90
4y - 6 = 90
4y = 96
y (the smaller angle) = 24°
x (the larger angle) = 3y - 6 = 3×24 - 6 = 72 - 6 = 66°

Answers
Pedro requires [tex]1\frac{1}{2}[/tex] cups oatmeal for a single batch of granola bars as calculated by division of fractions.
A fraction is a piece of a whole or, to put it more broadly, any number of equal portions.
The Latin word fractus, which means "broken," is where the word fraction originates.A fraction, such as one-half, eight-fifths, or three-quarters, indicates the number of components of a particular size as it is represented in common English. There is a non-zero denominator and a common, or simple fraction below (or after) that line.Compound fractions, mixed numeral fractions, and difficult fractions are examples of uncommon fractions that use numerators and denominators.Total batches required [tex]= 3 \frac{1}{2} = \frac{7}{2} = \frac{14}{4}[/tex] cups
Total oatmeal required [tex]= 5 \frac{1}{4} =\frac{21}{4}[/tex] cups
Therefore now to calculate the amount of oatmeal needed for single
batch we divide the fraction [tex]\frac{21}{4}[/tex] by [tex]\frac{14}{4}[/tex] cups
1 batch requires = [tex]=\frac{21}{4}\div\frac{14}{4}=\frac{3}{2} = 1\frac{1}{2}[/tex] cups.

Step-by-step explanation:
when the length of the shadow is 8ft, the actual height of the man = 5ft
8:5
let the giraffe be 'x' ft tall.
if the length of the shadow is 12ft, actual height = x ft
12:x
8:5 x 12:x
[tex]\frac{8}{5}[/tex] × [tex]\frac{12}{x}[/tex]
x= [tex]\frac{15}{2}[/tex]
x=7.5 ft
Therefore, the giraffe is 7.5ft tall.
Answer:
[tex]7.5\; {\rm ft}[/tex].
Step-by-step explanation:
The height of objects nearby under the sun are approximately proportional to the length of their shadows.
In other words, if the man and the giraffe are near each other and under the sun:
[tex]\begin{aligned} \frac{\text{height of man}}{\text{length of shadow of man}} = \frac{\text{height of giraffe}}{\text{length of shadow of giraffe}}\end{aligned}[/tex].
Given that:
[tex](\text{height of man}) = 5\;{\rm ft}[/tex], [tex](\text{length of shadow of man}) = 8\;{\rm ft}[/tex], and [tex](\text{length of shadow of giraffe}) = 12\; {\rm ft}[/tex].Rearrange the equation to find [tex](\text{height of giraffe})[/tex]:
[tex]\begin{aligned} (\text{height of giraffe}) &= (\text{length of shadow of giraffe})\times \frac{\text{height of man}}{\text{length of shadow of man}} \\ &= 12\; {\rm ft} \times \frac{5\; {\rm ft}}{8\; {\rm ft}} \\ &= 7.5\; {\rm ft}\end{aligned}[/tex].

A rectangular picture has dimensions of length (2x-1) inches and width (x+7) inches. The area of the picture is 108 in^2. What are the length and width of the picture?
Answers
The numerical length and width of the rectangular picture are 9in and 12in respectively.
What are the length and width of the picture?Area of a rectangle is expressed as;
A = length × width
Given the data in the question;
Length = 2x -1Width = x + 7Area = 108in²To determine the numerical length and width of the rectangular picture, first plug the given values into the equation and solve for x.
A = length × width
108 = (2x -1)(x+7)
Expand
108 = 2x² + 14x - 1x -7
108 = 2x² + 13x -7
Reorder
2x² + 13x -7 = 108
2x² + 13x - 7 - 108 = 0
2x² + 13x - 115 = 0
Solve by grouping
(x-5)(2x+23) = 0
x-5 = 0, 2x+23 = 0
x = 5, 2x = -23
x = 5, x = -23/2
x = 5, x = -11.5
But the dimension cannot be negative, hence;
x = 5
Next, determine the numerical length and width.
Length = 2x - 1 = 2(5) - 1 = 10 - 1 = 9in
Width = x + 7 = 5 + 7 = 12in
Therefore, the numerical length and width of the rectangular picture are 9in and 12in respectively.
