Answer:
540x+680y<=20000
Step-by-step explanation:
x will be the number of laptops. Since they are $540 each, 540x is the amount spent on laptops, depending on how many (x) are purchased.
y will be the number if desktops. Since they are $680 each, 680y is the amount spent on desktops, depending on how many (y) are purchased.
Adding all the money spent on laptops and desktops, we get
540x + 680y. This amount must be less than the $20000. It can be exactly $20000 also. But it cannot be more than $20000.
540x+680y<=20000
Six times a number is 14 less than the opposite of that number. What is the number?
Answer:
2
Step-by-step explanation:
6 x 2 = 12
12 is less than 14
Question :
Six times a number is 14 less than the opposite of that number. What is the number?Solution :
Let's assume the number as " x "
According to the question :
Six times a number is 14 less than the opposite of that number.We already assumed that the number is x. So, opposite of the number would be -x.
[tex]\qquad \sf \: { \dashrightarrow 6x= - x-14}
[/tex]
Now, let's solve this equation :
[tex]\qquad \sf \: { \dashrightarrow 6x + x= -14}
[/tex]
Combining the like terms :
[tex]\qquad \sf \: { \dashrightarrow 7x = - 14}
[/tex]
Then divide both sides by 7 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{7x}{7} = - \dfrac{14}{7} }
[/tex]
[tex]\qquad \sf \therefore \: \bf{{ x= -2}}
[/tex]
Therefore, the required number is -2 .

E) Width m, Length 6 + 8, Area as a product of width times length m(6 + 8), Area as a sum of the areas of smaller rectangles m6 + m8
F) Width 5, Length 3x + 8, Area as a product of width times length 5(3x + 8), Area as a sum of the areas of smaller rectangles 5(3x) + (5*8)
Step-by-step explanation:
Area would be the width times length and for the areas as the sum you would just calculate the area of the smaller rectangles and add them.

I think the answer is 3.
Step-by-step explanation:
The formula for the volume of a prism is V=Bxh, where B is the base area and h is the height.
Since we know that the volume is equivalent to 48 cubic feet, and the base area is 16 square feet.
We can divide the volume by the base to find the height of the crate.
48÷16=3

A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path. A circle has a radius of 28 feet. A larger circle goes around the smaller circle that is 4 feet wide. About how many feet of fencing are needed to go around the pool path? Use 3. 14 for Pi. 88 ft 100 ft 176 ft 201 ft.
There is 201 feet of fencing are needed to go around the pool path.
Given
A circular swimming pool has a radius of 28 ft.
There is a path all the way around the pool that is 4 ft wide.
A fence is going to be built around the outside edge of the pool path.
A circle has a radius of 28 feet.
A larger circle goes around the smaller circle that is 4 feet wide.
Circumference;For the length of the fence, we need to find the circumference of the outside of the pool path.
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= 28 + 4 = 32 feet
The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter;
[tex]\rm Perimeter = 2\pi r[/tex]
Where r is the radius.
Substitute all the values in the formula;
[tex]\rm Perimeter = 2\pi r\\\\\rm Perimeter = 2\times 3.14 \times 32\\\\Perimeter = 201[/tex]
Hence, there is 201 feet of fencing are needed to go around the pool path.

what is the equation of a vertical line that passes through (3, -10)
[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]
A vertical line is always parallel to y - axis, I.e the x - coordinates of the points on the line never changes
Therefore, the equation of the line will be ~
[tex]\qquad \sf \dashrightarrow \: x = 3[/tex]
And on this line, for each value of y, there is same value of x ~
The required equation of a vertical line that passes through (3, -10) is x = 3
Equation of a lineThe equation of a line in point slipe form is expressed as:
y - y1 = m(x-x1)
The equation of a vertical line is given as x = a
The value of a is the x coordinate of the given point. Hence the value of a = 3

A teacher wants to find the average (mean) grade on a math test. The gradebook program can provide data about the class as a stem-and-leaf plot or as a box-and-whisker plot. Which plot should she use? Why?
Answer:
Box-and-whisker plot
Step-by-step explanation:
Box-and-whisker plot is a graph commonly used to not only find the mean but find the minimum, maximum, third and first quartile. In order to calculate the mean of a set of data, you have to rearrange the data and the middle number separating one half of the set, from the other half of the set is the mean. Box-and-whisker plot can accurately show the average grade on this math test.

There is a direct proportionality between volume and temperature (in Kelvin) of a gas. The volume of a sample of a gas at 277 Kelvin is 2.1883 L.
Which of the following shows a direct variation equation relating the volume V and the temperature T?
Options:
1. V= 0.0079T
2. V= 126.6T
3. T=606.2V
4. T= 0.0079V
Answer:
2. V= 126.6T4. T= 0.0079VExplanation:
V = kT
[ where k is constant ]
277 = k(2.1883)
k = [tex]\frac{277}{2.1883}[/tex]
k = 126.6
Therefore: V = 126.6TVk = T
277k = 2.1883
k = 2.1883/277
k = [tex]7.9 * 10^{-3}[/tex]
V * [tex]7.9 * 10^{-3}[/tex] = T
T = 0.0079V
Therefore T = 0.0079V

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case, it is specified that:
Total number of employed writers and authors: 153,000Some college experience but no degree : 12.4%Bachelor's degree or higher : 84.1%Let we have:
writers and authors with bachelor’s degree = N + writers and authors with some college experience and no degree
(so the number of writers and authors with bachelor’s degree is N more than writers and authors with some college experience but no degree)
Number of writers and authors with bachelor's degree = 12.4% of 153000
which is [tex]\dfrac{153000}{100} \times 12.4 = 18972[/tex]
Number of writers and authors with some college experience but no degree = 84.1% of 153,000 which is [tex]\dfrac{153000}{100} \times 84.1 = 128673[/tex]
Thus,
128,673 = N + 18972
or
N = 128,673 - 18972= 109,701
Thus,
Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701

Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
Answer:
Step-by-step explanation: i took the test.
The first point is ta x= - 3.
The function h(x) has a maximum value.
The graph of the function h(x) is given below.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
h(x) = 2 sin(2x) - 3
The first point is at x = -3.
h'(x) = 4 cos(2x)
h''(x) = -8 sin(2x)
This means,
h(x) has a maximum value on the graph.
The graph of h(x) is given below.
Thus,
h(x) has a maximum value and the graph is given below.

Answer:
Following are the required equations
[tex]x +y=84[/tex]
[tex]6x +5y=440[/tex]
Step-by-step explanation:
Let x boxes of pecans and y boxes of peanuts sold.
Total no of boxes sold = 84
[tex]\implies x +y=84[/tex]
Cost of one box of pecan =$6
So, cost of x boxes of pecans =$6x
Cost of one box of peanuts = $5
