Given the equation of a line: y = (2/3)x + 1. Select the equation of the line PARALLEL to this line
Answer:
y = (2/3)x + K, where K is any number except 1
Step-by-step explanation:
In the slope-intercept form of the linear equation, y = mx +b, the 'm' is for the slope, m = 2/3.
Any line that also has a slope of 2/3 will be parallel.
y = (2/3)x - 10 will be parallel
y = (2/3)x + 12 will be parallel
y = (2/3)x - (1/2) will be parallel
y = (2/3)x + 5,391 will be parallel

Aaron is having rain gutters installed around the perimeter of his roof. How much will he spend if he is charged $3.50 per foot?
Answer:
$294.35
Step-by-step explanation:
left and right side of the house: 15 ft + 15 ft = 30 ft
top part of the house: (20 ft - 12 ft = 8 ft) 8ft + 9.6 ft + 7.5 ft = 25.1
bottom part of the house: (20 ft - 15 ft = 5 ft) 15 ft + 5 ft + 4. 5 ft + 4.5 ft = 29
30ft + 25.1ft + 29ft = 84.1
84.1 ft x $3.50 = 294.35
find the area of the circle use 3.14 for pi. 9ft
Answer:
0.29 m² or 0.30(approx)
Step-by-step explanation:
1 foot = 0.305m
so Area of circle is
= pi * r²
= 3.14 * (0.305)²
= 0.2920.... ~ 0.30m²
1/R = 1/A + 1/B assuming that all denominators are non-zero solve for B
Answer:
1/B = 1/R - 1/A
B/R - B/A = 1

Step-by-step explanation:
3. A company makes a profit of $15 per software program and $10 per video game. The company can produce
at most 70 software programs and at most 80 video games per week. Total production cannot exceed 100
items per week. How many items of each kind should be produced per week in order to maximize the profit?
Use linear programming to solve. Show all your work.
Answer:
For the profit to be maximized, 20 software programs and 80 video games should be produced
Step-by-step explanation:
Let x represent the number of the software programs and let y represent the number of video games.
We are told that the company can produce at most 70 software programs and then, at most 80 video games per week. Thus;
x ≤ 70
y ≤ 80
Also, we are told that the overall production cannot exceed 100. Thus;
x + y ≤ 100
Since the company makes a profit of $15 per software program and $10 per video game. Then, the function to be maximized is;
15x + 10y
When they produce at most 70 software programs, it means that the number of video games that can be produced is: 100 - 70 = 30.
Thus, one point of maximizing values is; (70, 30)
Also, when they produce at most 80 video games per week, the number of software programs that can be produced is; 100 - 80 = 20.
Thus, second point of maximization is;
(20, 80)
Putting these points into the objective function, we have;
At (70, 30); 15(70) + 10(30) = $1350
At (20, 80); 15(20) + 10(80) = $1100
For the profit to be maximized, 20 software programs and 80 video games should be produced

Measures of dispersion are used in finance as a proxy for risks. explain
Answer:
Kindly check explanation
Step-by-step explanation:
Measures of dispersion are used to determine the variability of data points of samples ; it measures how much a given data deviates or behaves about the mean value or point. Measures of dispersion or variability include standard deviation and variance.
In finance, data with high degree of vatibalitu are considered as being unstable because this shows a high level of uncertainty about the average confidence of the output for such investment or business. Hence. Highly variable investments are cindisderdd volatile and risky

Solve for the missing side
Answer:
8 ft
Step-by-step explanation:
By Pythagoras Theorem
[tex]x = \sqrt{ {10}^{2} - {6}^{2} } \\ \\ x = \sqrt{100 - 36} \\ \\ x = \sqrt{64} \\ \\ x = 8 \: ft[/tex]
Answer: It's 8 :)
Step-by-step explanation: Do the Pythagorean Theorem. a^2 + b^2 = c^2. In every case, c is the hypotenuse, so you do 10^2 = 6^2 + x^2. Then, it becomes 100 = 36 + x^2, then subtract 36 and you get 64. Then, you square root both sides to get 8. Have a great day!

tamie uses 2/3 of a cup of water with 1/6 of a pound of flour to make a paste for a sculpture she is creating how many cups of water does she need to mix 1 pound of flower to create the same paste
Answer: 12/18
Step-by-step explanation:
For a quick explanation, all you need to do is multiply 1/6 by 6 to get 1 whole and do the same to 2/3 so it’s proportional again.
The number of cups of water she needs to mix is 4.
Given that,
Tamie uses two-third of a cup of water with one-sixth of a pound of flour to make a paste for a sculpture.
Based on the above information, the calculation is as follows:
[tex]= \frac{2}{3} \div \frac{1}{6} \\\\= \frac{2\times 6}{3\times 1 }[/tex]
= 4

The vertices of ∆ABC are A (0,0), B (6,0) and C (6,6). Draw the triangle and its
image ∆ A’B’C’ translated to the right 3 units. What are the coordinates of the
vertices of ∆ A’B’C’?
Answer:
50 squirrels, 60 inches, A'(3,0), B'(9,0), C'(9,6)
Step-by-step explanation:
Given that the ratio of birds to squirrels is 4:5 and there are 90 altogether, define a variable [tex]x[/tex], and [tex]4x + 5x = 90[/tex], and [tex]x = 10[/tex]. Since squirrels are the [tex]5x[/tex] part, [tex]5\cdot10 = 50[/tex] squirrels.
1/5 of her total height is 12 so let's say her total height is [tex]h[/tex] and [tex]\frac{1}{5}h = 12[/tex].
Solve for [tex]h[/tex] to get 60 inches.
Translating this triangle to the right 3 units just means adding 3 to all the x coordinates of the vertices. This gives you A'(3,0), B'(9,0), C'(9,6).
