Lucia ran 4 miles every morning before she went to work. She did not work on Sundays. How many miles did Lucia run in a week?
Answer:
24 miles
Step-by-step explanation:
There are 7 days a week. Lucia didn't run on Sunday, so she ran 6 days.
4 miles per day x 6 days = 24 miles.
The length of a rectangular field is represented by the expression 14x-3x^2+2y . The width of the field is represented by the expression 5x-7x^2+7y . How much greater is the length of the field than the width?
The length of the field is greater than the width by the expression \((14x - 3x^2 + 2y) - (5x - 7x^2 + 7y).\)
1. The length of the field is represented by the expression \(14x - 3x^2 + 2y.\)
2. The width of the field is represented by the expression \(5x - 7x^2 + 7y\).
3. To find the difference between the length and width, we subtract the width from the length: (\(14x - 3x^2 + 2y) - (5x - 7x^2 + 7y\)).
4. Simplifying the expression, we remove the parentheses: \(14x - 3x^2 + 2y - 5x + 7x^2 - 7y.\)
5. Combining like terms, we group the \(x^2\) terms together and the x terms together: \(-3x^2 + 7x^2 + 14x - 5x + 2y - 7y.\)
6. Simplifying further, we add the coefficients of like terms:\((7x^2 - 3x^2) + (14x - 5x) + (2y - 7y).\)
7. The simplified expression becomes: \(4x^2 + 9x - 5y.\)
8. Therefore, the length of the field is greater than the width by the expression \(4x^2 + 9x - 5y.\)

a girl attaches a rock to a string, which she then swings counterclockwise in a horizontal circle. the string breaks at point p on the sketch, which shows a bird's-eye view (as seen from at at the right). what path will the rock follow?
The correct option B. Path B: since velocity v is tangent to a circular path.
Explain the term tangential velocity?Any linear component of an object's motion that travels a circular path is called tangential velocity.
A vector is a quantity with both magnitude and direction, according to the definition of physics. As an illustration, velocity is indeed a vector whose magnitude is speed. Distance divided by the time equals speed.The direction anywhere at given location on the circle is always following the tangent line when speaking of tangential velocity, which describes motion along a circle's periphery. We refer to the speed in our equation as "tangential velocity" since we grasp the concept of tangential direction.Thus, the rock will follow path B since velocity v is tangent towards the circular path.

The population of a village is in the following ratios.
women: children = 13:4
men: children = 7:3
a) Find the ratio women : men.
Give your answer in its simplest form.
women : men
Answer:
13:7
Step-by-step explanation:
We see that the ratio from women:children is 13:4.
Therefore, the number of women is 13.
In the ratio comparing men to children we see that it is 7:3.
Therefore, the number of men is 7.
Now we need to compare the number of women to the number of men which is 13:7.
The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

what's the inverse of f(x)=(x+3)^5
Answer:
The inverse is,
\(f^{-1}(x) = \sqrt[5]{x} - 3\)
Step-by-step explanation:
f(x) = (x+3)^5
Finding the inverse,
\(f(x) = (x+3)^5\\or,\\y = (x+3)^5\)
We replace x with y and vice versa
so,
\(x = (y+3)^5\)
Solving for y,
the the 5th root,
\(\sqrt[5]{x} = y + 3\\y = \sqrt[5]{x} - 3\)
hence the inverse function is,
\(f^{-1}(x) = \sqrt[5]{x} - 3\)
Step-by-step explanation:
f(x)=(x+3)×5
Y=5X+15
now
interxchanging x and y we get,
x=5y+15
5y=x-15
y=x-15/5
therefor f~1(x)=x-15/5

HCF of x minus 2 and X square + X - 6
Answer:
\( \boxed{ \sf{ \bold{ \huge{ \boxed{x - 2}}}}}\)Step-by-step explanation:
\( \sf{x - 2} \: and \: { {x}^{2} + x - 6}\)
To find the H.C.F of the algebraic expressions, they are to be factorised and a common factor or the product of common factors is obtained as their H.C.F
Let's solve
First expression = x - 2
Second expression = x + x - 6
Here, we have to find the two numbers which subtracts to 1 and multiplies to 6
= x + ( 3 - 2 ) x + 6
Distribute x through the parentheses
= x + 3x - 2x + 6
Factor out x from the expression
= x ( x + 3 ) - 2x + 6
Factor out -2 from the expression
= x ( x + 3 ) - 2 ( x + 3 )
Factor out x+3 from the expression
= ( x + 3 ) ( x - 2 )
Here, x - 2 is common in both expression.
Thus, H.C.F = x - 2
Hope I helped!
Best regards!!!
Answer:
x - 2
Step-by-step explanation:
by factorization method
1) x - 2
2) x^2 + x - 6
by splitting method
x^2 + 3x - 2x - 6
taking separate common from the first two terms and last two terms
x(x + 3) - 2(x + 3)
now writing x+3 once and the other term to get the right answer
(x + 3)(x - 2)
in both parts just see the similar term and write it as HCF
HCF= x - 2

Write an equation in slope-intercept
form to represent the line
perpendicular to 6y = 9 - x with
y-intercept 2
O y = -6x + 2
O y = 2x + 9
Answer:
A, y= -6x + 2
Step-by-step explanation:
1. Put the equation into slope intercept form
6y = 9 - x
y= -1/6x + 9/6
The slope of equation 1 is -1/6
2. A perpendicular line is the inverse slope of our firsy equation. (-1/6)^-1 = -6.
3. The y intercept of a line in slope intercept form is the b value in the equation as written:
y=mx+b
Therefore, if m=-6 and b=2, our equation is
y= -6x + 2

rotation 90 degrees counterclockwise about the origin
I'm going to try my best to explain 90° rotation:
So, you know that if you rotate something 180°, it's completely flipped (think about spinning around half-way).
Or if you spin something 360°, you spin around the whole way and end up in the same spot that you did when you started.
Notice how 90 is actually 1/4 of 360.
So imagine spinning instead of 180, spinning half of that. so you barely rotate. That's exactly what you're doing to this shape here. and if you do it about the origin counterclockwise, the origin is (0,0) so I drew it in Quadrant III, as you can see in my attachment.
You can see that every point has been moved by 90°, I put all of the variables there so you could visualize it better!
