If Marie were to paint her living room alone, it would take 7 hours. Her sister Barbara could do the job in 8 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.
Answer:
[tex]\sf\longmapsto \: 3.73 hours [/tex]
Step-by-step explanation:
[tex]\sf\longmapsto \: \frac{1}{7 } + \frac{1}{8} [/tex]
[tex]\sf\longmapsto \: \frac{15}{56} [/tex]
Now, Reciprocal–
[tex]\sf\longmapsto \: \frac{56}{15} [/tex]
[tex]\sf\longmapsto \: 3.73 hours [/tex]
The time taken together Marie and his sister to paint the living room are 3.73 hours or 3 hours and 43.8 minutes.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour.
Given that,
Marie take 7 hours to paint
1 work → 7 hour
1 hour → (1/7) work
Barbara takes 8 hour
1 work → 8 hour
1 hour → (1/8) work
Let's suppose together they take x hour
1 work → x hour
1 hour → (1/x) work
Now,
1-hour work together = 1-hour work of Marie + 1-hour work of Barbara
(1/x) = (1/7) + (1/8)
(1/x) = (7 + 8)/56
x = 56/15
x = 3.73
x = 3 hour and 0.73 × 60 = 43.8 minutes.
Hence "The time taken together Marie and his sister to paint the living room is 3.73 hours or 3 hours and 43.8 minutes".

Step-by-step explanation:
Let x be the number of books and y the number of CDs,
[tex]x+y=25\\[/tex]
The prices of the products are multiplied with the quantity bought, therefore:
[tex]1.5x + 5y = 65.50[/tex]
Multiplying the first equation by -5, then multiplying the two equations:
[tex]-3.5x=-59.5\\x=17[/tex]
Solve for the unknown angles
Marking you the brainliest provided you got it
right and with step by step explanation
Step-by-step explanation:
The angles a and b are congruent, also c and x are congruent.
a = b = 180° - 85° = 95° (supplementary, linear pair)c = x = 85° (corresponding, alternate interior)simplify:
[tex]x ^{4} - {x}^{2} {y}^{2} + {y}^{4} [/tex]

. The temperature fell 13°c on each of the first 2 days of the week. It rose 7°c on each of
the next 3 days and fell 9°c on each of the last 2 days. If the temperature was originally
34% what was the final temperature?
Answer:
The final temperature was 9 degrees.
Step-by-step explanation:
You can first multiply 13x2, 7x2, and 9x2. Then you subtract 26 and 18 from 34. then add 14

-3x-5y=-7
Find slope of perpendicular line
Answer:
5/3
Step-by-step explanation:
We need to rewrite the equation in slope intercept form
y =mx +b where m is the slope
-3x-5y = 7
Add 3x to each side
-5y = 3x+7
Divide by -5
y = -3/5 x -7/5
The slope of this line is -3/5
Perpendicular lines have slopes that are negative reciprocals
-1 / (-3/5)
5/3
The slope of the perpendicular line is 5/3
PLEASE HELP!!!!! A satellite telescope has a parabolic dish. Satellite signals are collected at the focal point (focus) of the
parabola. The distance from the vertex of the parabolic dish to the focus is 40 feet. The vertex of the dish is
located at a point 50 feet above the ground and 100 feet to the east of a computer that reads and records
data from the telescope. The diameter of the dish is 160 feet.
The dish illustrates operations on a parabola.
The depth of the parabolish dish is 160 feet.
The bowl is said to be a parabola.
So, we have:
[tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]
Where:
[tex]\mathbf{Focus: p = 40}[/tex]
[tex]\mathbf{Vertex:(h,k) = (0,0)}[/tex]
From the question, the diameter is 160 feet.
So, the radius (r) is:
[tex]\mathbf{r = \frac{160}{2} = 80}[/tex]
So, the coordinate of the depth of the parabola would be:
[tex]\mathbf{(x,y) = (60 + 100,y)}[/tex]
[tex]\mathbf{(x,y) = (160,y)}[/tex]
Substitute these values in [tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]
So, we have:
[tex]\mathbf{(160 - 0)^2 = 4 \times 40 \times (y -0)}[/tex]
[tex]\mathbf{160^2 = 160y}[/tex]
Divide both sides by 160
[tex]\mathbf{160 = y}[/tex]
Rewrite as:
[tex]\mathbf{y = 160 }[/tex]
Hence, the depth of the parabolish dish is 160 feet.

rectangular equation for the curve whose parametric equations are x = 2cosθ, y = cos2θ.
The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].
In this question, we have a set of parametric equation which must be reduced into a single rectangular equation both by algebraic and trigonometric means, that is to say:
[tex]x = f(\theta), y = g(\theta) \to y = h(x)[/tex]
If we know that [tex]x = 2\cdot \cos \theta[/tex] and [tex]y = \cos 2\theta[/tex], then the rectangular equation is:
[tex]y = \cos 2\theta[/tex]
[tex]y = \cos^{2}\theta - \sin^{2}\theta[/tex]
[tex]y = 2\cdot \cos^{2}\theta -1[/tex]
[tex]\cos \theta = \frac{x}{2}[/tex]
[tex]y = 2\cdot \left(\frac{x}{2} \right)^{2}-1[/tex]
[tex]y = \frac{x^{2}}{2} -1[/tex]
