how to solve for x and round it up to tenth
Answer:
4.6
Explanation:
The diagram shown is a right triangle having the following sides;
Opposite = 17
Adjacent = x
Angle of elevation = 75 degrees
Using SOH CAH TOA identity
Tan theta = opposite/adjacent
Tan 75 = 17/x
x = 17/tan 75
x = 17/3.73205
x = 4.6
Hence the value of x to the nearest tenth is 4.6

A mother need 6 pieces of ribbon, with lengths of 25 cm each, for her daughter's hair. If the ribbon is only sold per full meter, how many meters does she need to buy?
Given:
The length of each ribbon is 25 cm.
The number of ribbon need by mother is 6.
Explanation:
Determine the length of ribbon for daughter's hair.
[tex]\begin{gathered} 25\cdot6=150\text{ cm} \\ =1.5\text{ m} \end{gathered}[/tex]Since length is in decimal so we need to find multiple of 25 such that it is more than 150 and multiple of 100.
The multiples of 25 are 25,50, 75, 100, 125, 150, 175, 200, ...
Since 200 is more than 150 and multiple of 100 also.
Determine the length of 200 cm in terms of meters.
[tex]200\text{ cm}\cdot\frac{1\text{ m}}{100\text{ cm}}=2\text{ m}[/tex]So mother needs to buy 2 meters of ribbon.
Answer: 2 meters

To find the standard deviation of this set of numbers, we will use the formula
[tex]s=\sqrt{\frac{\sum_^(x-\text{ }x_{mean})^2\text{ }}{n-1}}[/tex]let us explain the parts of this formula, as follows:
[tex]x_{mean}\text{ is the mean of the data \lparen we have to calculate\rparen}[/tex][tex]n\text{ is the total quantity of numbers \lparen in this example 7\rparen}[/tex]We will proceed by parts, the first thing to do is find the mean of the data
Calculating the mean
To find the mean, we will sum all the numbers and divide by the total quantity of numbers, as follows:
[tex]x_{mean}=\frac{\Sigma x}{n}=\frac{38+47+43+44+44+41+44}{7}=\frac{301}{7}=43[/tex]That is, the mean of the set is 43. Now we proceed to find the difference between the data and the mean, and the add them to the power of two, in symbols we have:
[tex]\begin{gathered} \Sigma(x-x_{mean})^2=(38-43)^2+(47-43)^2+(43-43)^2+3\times\text{ }(44-43)^2+(41-43)^2 \\ \text{ =\lparen-5\rparen}^2+4^2+0^2+3\times\text{ }1^2+(-2)^2 \\ =25+16+3+4 \\ =48 \end{gathered}[/tex]Now we introduce this result into the formula for the standard deviation, we find:

If a one-person household spends an average of $52 per week on groceries, find the maximum and minimum amounts spent per week for the middle 50% of one-person households. Assume the standard deviation is $14 and the variable is normally distributed. Round your answers to the nearest hundredth.Minimum: $Maximum: $
Solution
For this case we have the following random variable:
X= amount spend on average for groceries by one person
And we have the following properties:
mean= 52
sd= 14
The distribution of the variable is normal
We can find the middle 50% using a graph like this one:
We can find two quantiles from the normal distribution that accumulates 25% of the area on each tail of the distribution and we have:
Z= -0.674 and 0.674
Now we can use the z score formula given by:
[tex]z=\frac{x-\mu}{\sigma},x=\mu\pm z\cdot\sigma[/tex]So then we have:
Minimum= 52 - 0.674*14 = 42.56
Minimum= 52 + 0.674*14 = 61.44

So, we are writing a function. c(x) is the manufacturing costs, and x is the amount of bikes manufactured. The y-intercept is 1908 because when no bikes are manufactured it still costs 1908 to run the factory. The slope is 75 because it costs $75 to create a bike. So, y = mx + b, where m is the slope and b is the y-intercept is:
c(x) = 75x + 1908
Prove that 3x + y = 7 + y and 3(x + y) = 2 + 3x are perpendicular
Answer:
Since one line is vertical, and one line is horizontal, the lines are perpendicular.
Step-by-step explanation:
The product of the slopes of perpendicular lines is -1.
We find the slopes of the 2 lines and multiply them together.
If the product equals -1, then the lines are perpendicular.
To find the slopes of the lines, we write each equation in the y = mx + b form, where m is the slope. In other words, we solve each equation for y.
3x + y = 7 + y
Subtract y from both sides.
3x = 7
x = 7/3
This is not the y = mx + b form since there is no y in the equation. A line with equation x = k, where k is a number, is a vertical line that passes through the point (k, 0), and the x-coordinate of all points on the line is k.
3(x + y) = 2 + 3x
3x + 3y = 2 + 3x
Subtract 3x from both sides.
3y = 2
y = 2/3
y = 0x + 2/3
Slope = m = 0
A line with 0 slope is a horizontal line.
Since one line is vertical, and one line is horizontal, the lines are perpendicular.

Total square inches of the floor = ______ square inches
One tile = _____ square inches
Total number of tiles needed =______ tiles
The number of tiles required to cover the floor is 2880 tiles.
What is the number of Tiles Needed?To solve this problem, we can find the number of tiles by calculating the area of a rectangle:
We have to convert the dimensions from feet to inches will be
1 feet = 12 inches
12 feet = 12 * 12 = 144in
15 feet = 12 * 15 = 180in
The area of the rectangle can be calculated as:
A = l * w
A = 180 * 144
A = 25920in²
The tiles are 9 squared inches, we can divide the area by 9 to find the number of tiles needed:
25920/9= 2880
Hence, The number of tiles needed will be 2880 tiles

Latoya opened a savings account and made an intial deposit. After the intial deposit, she added money into the account each week she added the same amount each week with out any withdrawals after the forth week she had $450 by the ninth week she had $825 what was latoya's intial deposit?
She made an initial deposit that we will call "D", as it is one of the unknowns.
We know that she made a weekly deposit (lets call this amount "w").
After 4 weeks she had $450 in the account balance and this is the sum of the initial deposit and 4 weekly deposits, so we can write:
[tex]D+4w=450[/tex]At the ninth week she had $825, that correspond to the initial deposit and 9 weekly deposits. This can be written as:
[tex]D+9w=825[/tex]We have a system of linear equations that we will solve by elimination: we will substract the first equation from the second and then find w.
[tex]\begin{gathered} (D+9w)-(D+4w)=825-450 \\ 5w=375 \\ w=\frac{375}{5} \\ w=75 \end{gathered}[/tex]Now that we know "w", we can calculate D with any of the two equations:
[tex]\begin{gathered} D+4w=450 \\ D+4\cdot75=450 \\ D+300=450 \\ D=450-300 \\ D=150 \end{gathered}[/tex]Answer: the initial deposit was $150.

The elements of the set given by A∩B is {12,18} .
Set theory, a branch of mathematical logic, studies sets, which are essentially collections of objects.
Despite the fact that every form of object may be turned into a set, set theory is a branch of mathematics that primarily deals with issues that are relevant to mathematics as a whole.
The foundation of set theory is a straightforward binary link between an object o and a set A.
If o is a component (or member) of A, it is expressed as o A. When listing members of a set, commas are used to indicate their separation, or brackets are used to surround a property of those parts.
Since sets are objects, they can be connected by the membership relation.
Given set U = {11,12,13,14,15,16,17,18,19,20}
A = {12,14,16,18,20}
B = {12,15,18}
A∩B = {12,18}
A∪B = {12,14,15,16,18,20}
