The expression that represents all the possible widths of the rectangle is given as follows:
0 < x < 5.
How to obtain the area of the rectangle?The area of a rectangle of length l and width w is given by the multiplication of these dimensions, as follows:
A = lw.
For this problem, the length is 5 meters more than five times the width, hence:
l = 5 + 5w.
Hence the area is given as follows:
A = w(5 + 5w)
A = 5w² + 5w.
The area is less than 100m², hence the inequality is given as follows:
5w² + 5w < 100
5w² + 5w - 100 < 0.
w² + w - 20 < 0.
(w + 5)(w - 4) < 0.
Hence the solutions are:
w + 5 < 0 -> w < 5.w - 4 < 0 -> w > -4.The width cannot be negative, hence the interval is:
0 < x < 5.

27 - 4x + x² can be written in the form (x + a)²+ b, where a and b are numbers. Work out the values of a and b.
Answer:
To rewrite the expression 27 - 4x + x² in the form (x + a)² + b, we can complete the square.
Starting with x² + (-4x) + 27:
x² - 4x + 4x² = 4x² - 4x
Adding (4/2)² = 4 to both sides:
4x² - 4x + 4 = 4x² - 4x + 4
The expression is now in the form (x - 2)² + 0, so a = -2 and b = 0.
Therefore, 27 - 4x + x² = (x - 2)² + 0.

Find the surface area of the prism
I
Answer:
684sq in
Step-by-step explanation:
The surface area of a rectangular prism can be calculated by adding up the areas of all six faces. If the dimensions of the prism are 6 inches, 15 inches, and 12 inches, then the surface area can be calculated as follows:
2(lw + lh + wh)
where l is the length, w is the width, and h is the height.
Substituting the given values, we get:
2(6 * 15 + 6 * 12 + 15 * 12)
= 2(90 + 72 + 180)
= 2(342)
= 684 square inches
So, the surface area of the rectangular prism is 684 square inches.

hihi i need help with this question 11
Step-by-step explanation:
So working from the bottom
The last line for x > 20 shows 13 because of the top graph, the last line is 13 and there is nothing below it.
Now for x > 16, we go up a line and see 14
That's where you would add 14 + any number below it
14 + 13 = 27. So for x > 16, you'd write 27
Going up, we have X > 12. Same thing, we go up a line and see 19. So now we just add 29 and any number below that
19 + 14 + 13 = 46. So for x > 12, you'd write 46.
You'll do that for the rest of the table. hope that helps
Suppose that a motorboat is moving at 83 ft/s when its motor suddenly quits, and that 1 s later the boat has slowed to 23 ft/s. Assume that the resistance it encounters while coasting is proportional to the square of its velocity so that dv/dt =-kv^2 where k > 0. How far will the boat coast in the first 2 minutes after its motor quits?
The boat will coast approximately 16752.9 feet (or about 3.17 miles) in the first 2 minutes after its motor quits.
From the problem statement, we know that the velocity of the boat, v, changes from 83 ft/s to 23 ft/s over a period of 1 second. Therefore, we can write:
[tex]dv/dt = -k v^2[/tex]
Separating variables and integrating from v = 83 at t = 0 to v = 23 at t = 1, we get:
[tex]∫83^23 dv / v^2 = ∫0^1 -k dt[/tex]
=> [1/83 - 1/23] = k
So the equation for the velocity of the boat as it coasts is:
[tex]dv/dt = -[(1/83 - 1/23)] v^2[/tex]
The differential equation is separable:
[tex]dv/v^2 = -[(1/83 - 1/23)] dt[/tex]
Integrating both sides, we get:
-1/v = [(1/83 - 1/23)] t + C
where C is an integration constant. Using the initial condition v(0) = 83, we get:
C = -1/83
Substituting this back, we have:
-1/v = [(1/83 - 1/23)] t - 1/83
Solving for v, we have:
v(t) = 83 / [1 + (83/23 - 1) t]
To find the distance traveled, we integrate v(t) from t = 0 to t = 120:
s =[tex]∫0^120 v(t) dt[/tex]
Substituting v(t) and simplifying, we have:
s = 23 ln(1 + 3.6087t) + 60.391t + C
where C is another integration constant. Using the initial condition s(0) = 0, we get:
C = 0
Therefore, the distance traveled by the boat in the first 2 minutes after its motor quits is:
s = 23 ln(1 + 3.6087t) + 60.391t
Evaluating this expression at t = 120 seconds, we get:
s = 23 ln(433.044) + 7246.92 ≈ 16752.9 ft

Sam is paid $12.45 per hour for a 37.5 hour week plus 6% of sales for a week. What would Sam's sales have to be for him to earn $800 in a week?
Answer:
ok Let’s calculate the money Sam makes per week, not including sales (or Assuming $0 in sales):
Money per week =$6.45/hour×37.5 hours/week= $241.88/week
The money he Gains from sales must make up the difference, So
money from sales = $400−$241.88 = $158.12
This Money is only 6% or 0.06 of the total sales though, so
Total sales = $158.120.06 = $2635.33
of course, this is Assuming that the money per week is rounded up from $241.875 to $241.88 instead of down to $241.87, in which case Sam would Have to make $2635.50 in sales (about 17 cents more).

in how many ways can we arrange a standard deck of 52 cards so that all cards in a given suit appear contiguously (e.g., first all the spades appear, then all the diamonds, then all the hearts, and then all the clubs)?
There are 71,536,320 ways to arrange a standard deck of 52 cards so that all cards in a given suit appear contiguously.
There are 4 suits in a standard deck of 52 cards, and we need to arrange all the cards in a given suit contiguously. Once we choose a suit to be arranged in this way, we can treat it as a block of 13 cards that need to be arranged. Therefore, we have reduced the problem to arranging 4 blocks of 13 cards each, where each block represents a suit.
Within each suit, there are 13! ways to arrange the cards. However, once we arrange the cards in one suit, we fix the relative positions of the cards in the other suits. Therefore, we only need to consider the number of ways to arrange the suits themselves.
There are 4! = 24 ways to arrange the 4 suits. For each of these arrangements, there is only one way to arrange the cards within each suit contiguously. Therefore, the total number of ways to arrange the deck of cards so that all cards in a given suit appear contiguously is:

Una compañía de teléfonos ofrece dos planes mensuales. El plan a cuesta $15 más $0. 12 adicionales por cada minuto de llamadas. El plan b cuesta $8 más 0. 17 adicionales por cada minuto de llamadas
¿para cuantos minutos de llamadas los dos planes cuestan lo mismo?
¿cual es el costo al que dos planes cuestan lo mismo?
The two plans cost the same for 60 minutes of calls. And the two plans cost the same for 60 minutes of calls.
We can set the cost of the two plans equal to each other and solve for the number of minutes:
Plan A: $15 + $0.12x (where x is the number of minutes)
Plan B: $8 + $0.17x
$15 + $0.12x = $8 + $0.17x
Subtracting $8 from both sides:
$7 + $0.12x = $0.17x
Subtracting $0.12x from both sides:
$7 = -0.05x + $0.17x
Adding 0.05x to both sides:
$7 + 0.05x = $0.17x
Dividing both sides by 0.12:
x = (7 / 0.12) / (1 - 0.17/0.12) = 60 minutes
So the two plans cost the same for 60 minutes of calls. To find the cost, we can plug x = 60 into either equation:
Plan A: $15 + $0.12 x 60 = $15 + $7.20 = $22.20
Plan B: $8 + $0.17 x 60 = $8 + $10.20 = $18.20
So the two plans cost the same when there are 60 minutes of calls, and they both cost $18.20

R^2=2025
R=45
Answer:
b) 45cm
Step-by-step explanation:
by pythagoras theorem:
R² = P² - Q²
R² = 53² - 28² = 2809 - 784
R² = 2025
R = √2025
R = 45cm
Hope this helps!
HELP I REALLY NEED IT!!
Answer:
Below
Step-by-step explanation:
Since the center (h,k) is (4,1) and the circle passes through (4,-4) the radius is 5 ( from y = 1 to -4 ...a distance of 5 )
the equation for a circle is of the form (x-h)^2 + (y-k)^2 = r^2
becomes (x-4)^2 + ( y-1)^2 = 5^2 < ==== graph this equation
radius = 5 then the diameter = 10 then circumference = pi * d = 10 pi
What value of m would make parallelogram WXYZ asquare?2m + 4m+6
The value of m for which the parallelogram WXYZ will be a square is (a) 2 .
For the parallelogram WXYZ to be a square ,
We know that , if parallelogram WXYZ is a square all, then all the sides are equal ;
So , we write WX = XY = YZ = ZW ;
To find the value of "m" , we use WX = ZW ;
substituting the values of sides of square from the figure ,
we get ;
⇒ 2m + 4 = m + 6 ;
⇒ 2m - m = 6 - 4 ;
⇒ m = 2 ;
Therefore , the value of "m" for the square WXYZ is 2 .

phone models a particular cell phone company offers models of phones, each in different colors and each available with any one of calling plans. how many combinations are possible?
The number of combinations that are possible for 4 cell phone models of 6 colors with 5 calling plans is 120 .
We have to find the total number of combinations of cell phone models, colors, and calling plans,
So , we multiply the number of choices for each category.
By Using the multiplication principle of counting:
⇒ Total number of combinations = (number of phone models) × (number of colors) × (number of calling plans) ;
⇒ 4 × 6 × 5
⇒ 120
Therefore, there are 120 possible combinations of cell phone models, colors, and calling plans from this particular cell phone company.
