Becky and lewis´s hamster cages have the same perimeter. Lewis´s cage has a length of 0.75 times becky´s cage. what is the width, w, of Lewis´s cage? Write your answer as a mixed number in simplest form
The width of Lewis´s rectangular cage as a mixed number in simplest form is equal to 14.86 inches.
How to calculate the perimeter of a rectangle?Mathematically, the perimeter of a rectangle can be calculated by using this formula;
P = 2(L + W)
Where:
P represents the perimeter of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.For the perimeter of Becky's rectangular cage, we have:
Perimeter, P = 2(L + W)
Perimeter, P = 2(15 + 11)
Perimeter, P = 2(26)
Perimeter, P = 52 inches.
For the perimeter of Lewis's rectangular cage, we have:
Length, L = 0.75W
Perimeter, P = 2(L + W)
52 = 2(0.75W + W)
26 = (0.75W + W)
1.75W = 26
Width, W = 26/1.75
Width, W = 14.86 inches.

The plates that Mom bought are very fragile and expensive. She paid $16.68 per plate and there are eight plates. How much money did she spend on the plates? Show work.
The money spent on the plates which are very expensive is: $133.44
Given,
The plates that mom bought are very fragile and expensive.
Each plate costs $16.68.
Total plates bought by her mom are = 8
we are asked to determine the total cost of the plates bought = ?
let y represent the total cost of the plates.
and x represent the number of plates bought.
based on the conditions, we can formulate:
total cost pf plates = 16.38(number of plates bought)
⇒ y = 16.68x
we know that plates bought = 8
⇒ total cost is:
⇒ y = 16.68(8)
⇒ y = 133.44

Find how many quarts of 5% butterfat milk and 2% butterfat milk should be mixed to yield 90 quarts of 3% butterfat milk.
The mixture should contain ___ quarts of the 5% butterfat milk.
Answer:
The mixture should contain 30 quarts of the 5% butterfat milk.Step-by-step explanation:
Let the required amount of 5% milk is x quartz, then the amount of 2% milk is 90 - x quartz.
Set equation for the fat content:
5% of x + 2% of (90 - x) = 3% of 900,05x + 0.02(90 - x) = 0.03*900.05x + 1.8 - 0.02x = 2.70.03x = 2.7 - 1.80.03x = 0.9x = 0.9/0.03x = 30while exploring a volcano, Zane heard some rumbling, so he decided to climb up out of there as quickly as he could.
Zane's elevation relative to the edge of the inside of the volcano (in meters) as a function of time (in seconds) is graphed.
The time that it took Zane to reach the edge of the volcano is of:
35 seconds.
Where is the edge of the volcano?The variables that are graphed in this problem are listed as follows:
x-axis: Time.y-axis: Elevation relative to the volcano.The edge of the volcano is the point at which the elevation relative to the volcano is of 0, hence the coordinate is:
y = 0.
y = 0 is the x-intercept of the function, which is the value of x at which the function crosses the x-axis.
Hence, looking at the graph, the time that it took Zane to reach the edge of the volcano is of:

Which graph represents the polar curve r = 3 – 2cos(θ)?
The graph of the polar curve r = 3 – 2cos(θ) is in the attachment
What is a graph?A graph is a diagram representation on a coordinate system.
What is a polar curve?A polar curve is a curve represented by the equation r = a + bcosθ where
a and b are constants and θ = the argument of the curveHow to find the graph of the polar curve r = 3 – 2cos(θ)?To find the graph of the polar curve r = 3 – 2cos(θ), we need to determine its maximum and minimum values and also the value as it crosses the axis.
The maximum value of rSince r = 3 – 2cos(θ), the maximum value of r is obtained at the minimum value of cos(θ) = -1 at θ = π
So, substituting this into the equation, we have
r = 3 – 2cos(θ)
r = 3 – 2(-1)
r = 3 + 2
r = 5
The minimum value of rSince r = 3 – 2cos(θ), the minimum value of r is obtained at the maximum value of cos(θ) = 1 at θ = 0
So, substituting this into the equation, we have
r = 3 – 2cos(θ)
r = 3 – 2(1)
r = 3 - 2
r = 1
The value of r at the originSince r = 3 – 2cos(θ), the value of r at the origin is when θ = π/2 and θ = 3π/2
So, substituting this into the equation, we have
r = 3 – 2cos(θ)
r = 3 – 2cos(π/2)
r = 3 – 2(0)
r = 3 - 0
r = 3
So, in polar form, the points we require for the polar curve graph are

3. An object is launched at 190.6 meters per second (m/s). The equation for the object's height
s at time t seconds after launch is s(t) = -4.9t^2 + 190.6t + 58.8, where s is in meters.
a. What was the initial height of the object?
b. At what time will the object first hit the ground?
c. What was the maximum height reached by the object?
Considering the quadratic equation, it is found that:
a) The initial height of the object is of 58.8 meters.
b) The object first hits the ground after 39.2 seconds.
c) The maximum height reached by the object is of: 1912 meters.
What is the quadratic equation?The quadratic equation that models the projectile's height is defined as follows:
s(t) = -4.9t² + 190.6t + 58.8.
Which has the coefficients given as follows:
a = 4.9, b = 190.6, c = 58.8.
The initial height is obtained as follows:
s(0) = -4.9(0)² + 190.6(0) + 58.8 = 58.8 meters.
It hits the ground at the positive root for which s(t) = 0, hence, using a quadratic equation calculator, this root is of:
t = 39.2 seconds.
The maximum height obtained by the object is the y-coordinate of the vertex, hence:
hMAX = -(b² - 4ac)/4a = -(190.6² - 4(-4.9)(58.8))/(4(-4.9)) = 1912 meters.

The length of a rectangle is five times its width.
If the area of the rectangle is 245 ft^2 , find its perimeter.
Answer:
P = 84
Step-by-step explanation:
Area = length* width or A = lw
We know that the length is 5 times its width which can also mean
[tex]l = 5*w[/tex] or [tex]l=5w[/tex]
Use the formula for area and replace [tex]l[/tex] with [tex]5w[/tex] and the total area with 245
[tex]A = lw\\245=5w(w)[/tex]
Multiply:
[tex]245=5w^{2}[/tex]
Divide by 5
[tex]49=w^2[/tex]
Square root of [tex]w^2[/tex]
[tex]\sqrt{49}=\sqrt{w^2}[/tex]
Simplify
[tex]7=w[/tex]
Now that we know w = 7 we can input this into the Perimeter formula
(P = 2l +2w)
P = 2(5*7)+2(7) // Note: Remember [tex]l[/tex] = 5*w and w = 7
P = 84

Step-by-step explanation:
Find the local maximum of the function.

f(x)=2x3+15x2−36x+1
Please help! Thank you :D
The minimum and maximum of the function f(x)=2x³+15x²-36x+1 are 38 and 39 respectively
The maximum value of a function f(x) is also called the absolute maximum value, or the greatest value of the function f on the closed interval [0, 1]. on the other hand, the minimum value of f(x) at x = 0 is called the absolute minimum value, or least value of the function f on the closed interval [0, 1)
How to find the minimum and maximum functions?
From the function f(x) = 2x3 − 15x2 + 36x + 1.
Using differential calculus , dy/dx = 6x2 - 30x + 36
= 6(x2 - 5x + 6)
f(x) is a maximum when x = 2 and the maximum value of f(x) = f(2).
This implies that f(2) = 2(23) − 15(22) + 36(2) + 11 = 39
d2y/dx2|x=3 = 12 x 3 - 30 = 6 > 0
This also implies that f(x) is a minimum when x = 3 and the minimum value of f(x) = f(3) = 2(3)3 − 15(3)2 + 36(3) + 11 = 38

The length of a rectangle is 8 inches more than its width. If 4 inches are taken from the length and
added to the width, the figure becomes a square with an area of 196 square inches. What are the
dimensions of the original figure?
Answer:
18 in. x 10 in.
Step-by-step explanation:
Squares will always have equal lengths. So, you need to figure out what will multiple by itself to get 196, and it’s 14.
Since you know in the equation that if 4 were to be taken away from the length and added to the width, it would make the 14 x 14 square, you can subtract 4 from one of the 14’s and add 4 to the other 14.
So, then you get (14-4) 10 in. x (14+4) 18 in.

h(1) = -17
h(n) = h(n
1) - 0.2
Find an explicit formula for h(n).
h(n)
h(n) = -17·0.2^(n-1)
Step-by-step explanation:
The explicit formula for a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Your sequence h has first term a1 = -17 and common ratio r = 0.2. Then the explicit formula is ...
h(n) = -17·0.2^(n-1)
Evaluate the function at the given values.
