the length of a rectangular pen is 5 more than its width. The perimeter is 26 meters. Find the length and width.
a quarter is 1.75 millimeters thick. how high is a stack of 1000 quarters?
Thickness of 1 quarter = 1.75 mm
So, 1000 quarters will be = [tex]1000\times1.75[/tex]
= 1750 mm
So, a stack of 1000 quarters will be 1750 mm high.
To find the height of a stack of 1000 quarters, multiply the thickness of one quarter by the number of quarters in the stack and convert the result to meters.
To find the height of a stack of 1000 quarters:
Calculate the total thickness of 1000 quarters: 1.75mm x 1000 = 1750mm = 1.75m
1 meter = 1000 millimeters, so the height of a stack of 1000 quarters would be 1.75 meters.

The cost of a book is 90.5 and the tax is 4% what is the new cost
answer: $94.12
work:
let's start by finding the tax.
step one: convert the percentage into a decimal by dividing it by 100.
4 / 100 = 0.04
next, multiply your total by the tax
$90.5 x 0.04 = 3.62.
next, add the tax to the original price to see your new total.
$90.5 + $3.62 = $94.12
so, your total with tax would be $94.12.

In Microsoft Excel, you have data that has been entered into cell A1. You need a function that looks up this value from A1 in a table of values in E1 through F10. You need to have the value from the second column (F) be displayed in the cell in which you are writing this formula. Also, A1 will precisely match one of the values in the first column (E). What formula would you write to look up this information?
I'm going to assume that there is something in A1 but the way you are describing the problem, you could just as easily write a constant in the formula you are using in cells E1 to E10 and F1 to F10
The trick is to refer to A1 as $A$1 which means that E1 to E10 isn't going to get creative and start looking for things in a1 to a10.
Here is an actual table made from what I think you mean
1 113 114
2 114 116
3 115 118
4 116 120
5 117 122
6 118 124
7 119 126
8 120 128
9 121 130
10 122 132
1 to 10 on the left is in column D
A1 contains 112
In column E the enteries from 1 to 10 simply take = $A$1 + d1
Column F uses $A$1 and adds 2*d to 112
Here is the chart shown in formula form.
1 =D1+$A$1 =$A$1 + 2*D1
2 =D2+$A$1 =$A$1 + 2*D2
3 =D3+$A$1 =$A$1 + 2*D3
4 =D4+$A$1 =$A$1 + 2*D4
5 =D5+$A$1 =$A$1 + 2*D5
6 =D6+$A$1 =$A$1 + 2*D6
7 =D7+$A$1 =$A$1 + 2*D7
8 =D8+$A$1 =$A$1 + 2*D8
9 =D9+$A$1 =$A$1 + 2*D9
10 =D10+$A$1 =$A$1 + 2*D10
Remember that 1 to 10 is in d1 to d10
To look up a value from A1 in a table (E1:F10) and display the corresponding value from column F, use the formula =VLOOKUP(A1, E1:F10, 2, FALSE) in the desired output cell.
To look up the value in cell A1 from a table in E1 through F10 and return the value from the second column (F), you would use the VLOOKUP function. The appropriate formula to enter into the cell where you want to display the result would be =VLOOKUP(A1, E1:F10, 2, FALSE). This formula begins with an equal sign, as all Excel formulas do, and instructs Excel to find the value in cell A1 within the first column of the range E1:F10 and return the corresponding value from the second column of that range. The FALSE argument specifies that you want an exact match.

At 7am last night, the temperature was 10°F. At 7am the next morning, the temperature was -2°F. By how much did the temperature change from 7pm to 7am?
The temperature decreased by 12°F from 7pm to 7am.
Explanation:The temperature change from 7pm to 7am can be calculated by finding the difference between the temperatures at those times. At 7am last night, the temperature was 10°F.
At 7am the next morning, the temperature was -2°F. To find the temperature change, subtract the initial temperature from the final temperature: -2°F - 10°F = -12°F. Therefore, the temperature decreased by 12°F from 7pm to 7am.

which equation is the inverse of y=7x^2-10
y = 7x^2 - 10
Switch y and x.
x = 7y^2 - 10
Solve for y.
Add 10 to both sides.
x + 10 = 7y^2
Divide both sides by 7.
(x + 10)/7 = y^2
√ both sides.
√(x + 10)/7 = y
Replace y with f^-1(x)

The volume of a spherical tank is 790.272 pie cubic feet what is the diameter of the container
Answer:
The diameter is 13.88 feet.
Step-by-step explanation:
1. The formula for calculate the volume of a sphere is:
[tex]V=\frac{3}{4}(r^{3}\pi)[/tex]
Where [tex]r[/tex] is the radius.
2. The diameter is:
[tex]D=2r[/tex]
3. So, you must solve for the radius in the first equation:
[tex]r=\sqrt[3]{\frac{4V}{3\pi}}[/tex]
[tex]r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft[/tex]

Answer:
From the image we have,
[tex](11x-6)^{\circ}[/tex] and [tex](13y-14)^{\circ}[/tex] are linear pairs.
Linear Pair Theorem: If two angles form a linear pair, then they are supplementary.
therefore, by above theorem we have,
[tex]11x-6+13y-14=180^{\circ}[/tex]
simplify:
[tex]11x+13y=200^{\circ}[/tex]
Since, we can seen from the image we have, [tex]15x-8=90^{\circ}[/tex]
[tex]15x=98^{\circ}[/tex]
therefore, [tex]x=6.534^{\circ}[/tex]
Now, putting the value of x in equation [tex]11x+13y=200^{\circ}[/tex] to find for y:
[tex]11\cdot 6.534+13y=200^{\circ}[/tex]
[tex]71.8667+13y=200^{\circ}[/tex]
[tex]13y=200-71.867=128.134^{\circ}[/tex]
Therefore the values of [tex]x=6.534^{\circ}[/tex] and [tex]y=128.134^{\circ}[/tex]

What is the solution to the inequality? 17 < 9 + x
17 < 9 + x Subtract 9 from both sides.
17 - 9 < 9 - 9 + x
8 < x
Be very careful that you leave the open end of the less than symbol pointing towards the x It means that x is greater than 8.
You could write it the other way x > 8 but the pointy end must always be closest to the 7 which is another way of saying what the answer means.
Notice anything after the 8 going right is colored and it is the answer.
The volume of a square is V equals S to the fourth. The side of a square is 4X to the third, what is the volume of the square
note a square is a 2 dimensional figure and so cannot have volume.
However, the 3 dimensional solid you may mean is a cube and the volume of a cube is

A copier printS 89 copies in one minute .How long does it take the copier to print 1,858 copies
Answer: 20.87/21 minutes
Step-by-step explanation: 1858/2 = 20.8764044944
2 x 20.8764044944 = 1858
It takes approximately 21 minutes for the copier to print 1,858 copies, given that the copier prints at a rate of 89 copies per minute.
To determine how long it takes for the copier to print 1,858 copies, we can set up a proportion since we know the rate at which the copier prints is 89 copies per minute. We calculate the time it would take by dividing the total number of copies needed by the number of copies the machine can print per minute:
Time (in minutes) = Total Copies ÷ Rate
Time (in minutes) = 1,858 copies ÷ 89 copies per minute
After performing the division, we find that:
Time (in minutes) = 20.8764 minutes
Since we generally measure time in whole minutes when it comes to using office equipment, we can round this to the nearest whole number, thus giving us approximately 21 minutes to complete the printing task.
Vector has 4 orange picks for every three green picks. If 8 of the picks are orange, how many picks are green?
The answer is 6.
If we know that you get 3 greens for every 4 oranges then all we need to do is extrapolate.
The ratio of orange picks to green picks is 4:3. Given 8 orange picks, we use a proportion to find that there are 6 green picks. Therefore, there are 6 green picks.
To solve this, set up a proportion:
4 orange picks / 3 green picks = 8 orange picks / x green picksCross-multiply to find the value of x:
4 × x = 3 × 84x = 24Divide both sides by 4:
x = 6Therefore, there are 6 green picks.
Hence, if there are 8 orange picks, then there are 6 green picks.

Which size container of cold farm ice cream is the better deal for Sheldon? Explain.
Cold Farms:
Small box
1 pint = $2.50
1 quart = $4.50
Large Box
1 quart = 2 pints .
2 pints = $4.50
1 pint = $4.50 / 2 = $2.25
Cone Dreams:
Small box
1 quart = $4.25 and
1 pint = $4.25/2 = $ 2.125
Large Box
1 gallon = $9.50.
1 gallon = 8 pints
8 pints = $9.50.
1 pint = $9.50 / 8 = $ 1.1875.
Answer:
The larger size of the cold farm ice cream is the better deal . To get the equivalent volume of the small size to the large size , one needs to spend $2.5 + $2.5 = $5.0 where as for the larger size you will only spend $ 4.5.
Step-by-step explanation:
The price for cold farm ice cream for the small size is $2.5 for 1 pint and for the larger size it is $4.5 for 1 quarts. Sheldon wants to know the better deal for the size container of cold farm ice cream.
Firstly, the prices are in different volume unit we need to convert them to the same units.
1 pints = 0.5 quarts
That means small size of cold farm ice cream is $ 2.5 for 0.5 quart and larger size is $ 4.5 for 1 quart.
Small size
$2.5 for 0.5 quart
$5.0 for 1 quart
Larger size
$ 4.5 for 1 quart
The larger size of the cold farm ice cream is the better deal . To get the equivalent volume of larger size , one needs to spend $2.5 + $2.5 = $5.0 where as for the larger size you will only spend $ 4.5.
