The length of a rectangle is 3 times the width. The perimeter is 96 cm. Find the width and length.
Let width = X
Then length would = 3x
The perimeter is 2 times the length + 2 times the width, so half the perimeter would be the length plus the width.
L + W = 1/2 perimeter
L +w = 48
Replace L and W withe the variables from above:
3x + x = 48
Simplify:
4x = 48
Divide both sides by 4:
x = 48/4
x = 12
Now you have a value for x, replace x with 12 in the variables:
Width = x = 12 cm
Length = 3x = 3*12 = 36 cm
A bathtub in the shape of a rectangular prism is 20 feet long, 10 feet wide, and 5 feet deep. How much water could the tub hold?
Answer:
Step-by-step explanation:
Volume = length * width * height.
Volume = 20 * 10 * 5
The tub can hold 1000 cubic feet of water.
The amount of water tub hold is 28316.8 liters.
What is Volume?Space is used by every three-dimensional object. The volume of this space is used as a measurement. The volume of an object in three-dimensional space is the amount of space it occupies within its boundaries. The capacity of the object is another name for it.
An object's volume can help us figure out how much water is needed to fill it, like how much water is needed to fill a bottle, aquarium, or water tank.
Given shape of bath tub is rectangular prism
which is 20 feet long, 10 feet wide, and 5 feet deep
length = 20 feet
width = 10 feet
height = 5 feet
to find the capacity of tub we need to calculate volume of tub
volume for rectangular prism = l x b x h
V = 20 x 10 x 5 = 1000 cubic feet
and 1 cubic feet = 28.3168 liter
1000 cubic feet = 28316.8 liter
Hence, the capacity of tub is 28316.8 liters.

Answer:
11.3cm = RC
Step-by-step explanation:
We can find the radius by using Pythagorean theorem and finding RC
a^2 + b^2 = c^2
RQ^2 + QC^2 = RC^2
We are given QC = 8
QC is the perpendicular bisector of PR so QR is 1/2 PR
QR = 1/2 (16) = 8
RQ^2 + QC^2 = RC^2
8^2 + 8^2 = RC^2
64+64 = RC^2
128 = RC^2
Take the square root of each side
sqrt(128) = sqrt(RC^2)
11.3137 = RC
Rounding to the nearest tenth
11.3cm = RC
Ice-Cream Palace needed 6 gallons of milk today to make their daily special. They had 6 1?2 quarts of skim milk and 1 pint of whole milk. How many pints of milk did they still need to buy?
The Ice-Cream Palace needed to buy 34 more pints of milk to reach their requirement for the daily special, as they only had 14 pints and required 48 pints in total.
Explanation:To solve this question, we need to convert all the quantities to the same unit. In this case, we'll use pints, since it's the smallest unit given. We know that 1 gallon equals 4 quarts, and 1 quart equals 2 pints. Therefore, 1 gallon equals 8 pints.
Ice-Cream Palace needed 6 gallons of milk, which is 6 * 8 = 48 pints. They already had 6 1/2 quarts of skim milk and 1 pint of whole milk. The 6 1/2 quarts equals 6.5 * 2 = 13 pints.
So, in total, Ice-Cream Palace had 13 pints + 1 pint = 14 pints of milk. This means they still needed to buy 48 - 14 = 34 pints of milk for their daily special.

The Ice-Cream Palace does not need to buy any more pints of milk because they already have more milk than they need.
Explanation:To find the number of pints of milk the Ice-Cream Palace still needed to buy, we first need to convert the given quantities to the same unit. Since we need to find the number of pints, we'll convert the 6 gallons and 6 1/2 quarts to pints.
1 gallon = 4 quarts = 8 pints
So, 6 gallons = 6 x 8 = 48 pints
1 quart = 2 pints
So, 6 1/2 quarts = 6 x 2 + 1 x 2 = 12 + 2 =14 pints
1 pint is already given as 1 pint.
Now, to find the number of pints of milk still needed to buy, we subtract the total amount of milk they already have (48 pints + 14 pints + 1 pint) from the amount they need (6 gallons = 48 pints).
48 pints (needed) - (48 pints + 14 pints + 1 pint) (already have) = 48 pints - 63 pints = -15 pints
Since the result is negative, it means they have more milk than they need. So, they don't need to buy any more pints of milk.

(a) Wild guess:
[tex]f(x)=\dfrac1{(6+x)^2[/tex]
Recall the power series
[tex]\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n[/tex]
With some manipulation, we can write
[tex]\displaystyle\frac1{6+x}=\frac16\frac1{1-\left(-\frac x6\right)}=\frac16\sum_{n=0}^\infty\left(-\frac x6\right)^n=\sum_{n=0}^\infty\frac{(-x)^n}{6^{n+1}}[/tex]
Take the derivative and we get
[tex]\displaystyle-\frac1{(6+x)^2}=-\sum_{n=0}^\infty\frac{n(-x)^{n-1}}{6^{n+1}}[/tex]
[tex]\displaystyle=-\sum_{n=1}^\infty\frac{n(-x)^{n-1}}{6^{n+1}}[/tex]
[tex]\displaystyle=-\sum_{n=0}^\infty\frac{(n+1)(-x)^n}{6^{n+2}}[/tex]
so we have
[tex]\displaystyle\frac1{(6+x)^2}=\sum_{n=0}^\infty\frac{(n+1)(-x)^n}{6^{n+2}}[/tex]
By the ratio test, this series converges if
[tex]\displaystyle\lim_{n\to\infty}\left|\frac{\frac{(n+2)(-x)^{n+1}}{6^{n+3}}}{\frac{(n+1)(-x)^n}{6^{n+2}}}\right|=\left|\frac x6\right|\lim_{n\to\infty}\frac{n+2}{n+1}=\left|\frac x6\right|<1[/tex]
or [tex]|x|<6[/tex], so that the radius of convergence is [tex]R=6[/tex].
(b). If we take the second derivative, we get
[tex]\displaystyle\frac2{(6+x)^3}=\sum_{n=0}^\infty\frac{n(n+1)(-x)^{n-1}}{6^{n+2}}[/tex]
[tex]\displaystyle=\sum_{n=1}^\infty\frac{n(n+1)(-x)^{n-1}}{6^{n+2}}[/tex]
[tex]\displaystyle=\sum_{n=0}^\infty\frac{(n+1)(n+2)(-x)^n}{6^{n+3}}[/tex]
[tex]\displaystyle\frac1{(6+x)^3}=\frac12\sum_{n=0}^\infty\frac{(n+1)(n+2)(-x)^n}{6^{n+3}}[/tex]
Apply the ratio test again and we get [tex]R=6[/tex].
(c) Multiply the previous series by [tex]x^2[/tex] and we get
[tex]\displaystyle\frac{x^2}{(6+x)^3}=\frac12\sum_{n=0}^\infty\frac{(n+1)(n+2)(-x)^nx^2}{6^{n+3}}[/tex]

Earth's equator is about 24,902 mi long. What is the approximate surface area of Earth?
Answer:
197 million square miles
Step-by-step explanation:
Remark
What the equator is telling you is that the circumference around the earth is approximately 24902 miles. So before you can find the surface area, you need to find the radius of that circumference.
Equations
C = 2*pi*r
Area = 4pi*r^2
Solution
Radius
C = 24902
pi = 3.14
r = ?
24902 = 2 * pi * r
r = 24902 / (2 * pi)
r = 3965.29
==========
Surface Area
Area = 4 * pi * r^2
Area = 4 * 3.14 * 3965.29^2
Area = 4 * 3.14 * 15,723,498
Area = 197 000 000 square miles
Final answer:
The approximate surface area of the Earth, an oblate spheroid, is calculated using the mean radius derived from the average of the equatorial and polar radii, resulting in an estimated surface area of around 197 million square miles.
Explanation:
Calculating Earth's Surface Area
To approximate the surface area of the Earth, we will use the formula for the surface area of a sphere, which is 4πr². Since the Earth is not a perfect sphere but rather an oblate spheroid, we will use the mean radius. The equatorial radius is approximately 3963.296 miles, and the polar radius is 3949.790 miles. Thus, the mean radius would be the average of these two measurements.
First, we calculate the mean radius:
(3963.296 + 3949.790) / 2 = 3956.543 miles
Now, plug the mean radius into the formula for the surface area of a sphere:
Surface Area = 4π(3956.543)² ≈ 197,000,000 square miles
This calculation provides an approximation of the Earth's surface area, taking into account its oblate spheroid shape.
Suppose a homeless shelter provides meals and sleeping cots to those in need. A rectangular cot measures 6 feet long by 3 ½ feet wide. Find the cot's diagonal distance from corner to corner. Round your answer to the nearest hundredth foot. 6.95 feet 9.64 feet 9.65 feet 6.94 feet
Answer:
6.95 feet
Step-by-step explanation:
The shape of the cot is rectangular. A diagonal of the rectangle divides the rectangle into two Congruent Right Angled triangles. The length and width of the rectangle become the legs of the right triangle and the diagonal is the hypotenuse of the right triangle.
In order to find the length of the hypotenuse which is the diagonal in this case we can use the Pythagoras Theorem. According to the theorem, square of hypotenuse is equal to the sum of square of its legs. So for the given case, the formula will be:
[tex]\textrm{(Diagonal)}^{2}=\textrm{(Length)}^{2}+\textrm{(Width)}^{2}\\\\ \textrm{(Diagonal)}^{2}=6^{2}+3.5^{2}\\\\ \textrm{(Diagonal)}^{2}=48.25\\\\ \textrm{(Diagonal)}=\sqrt{48.25}=6.95[/tex]
Thus, rounded of to nearest hundredth foot, the diagonal distance from corner to corner is 6.95 feet
A 5-ounce can of tuna costs $0.90. A 12-ounce can of tuna costs $2.40. Which is the better buy?
Hello there!
To find which tuna is a better deal, divide the cost by the number of ounces of tuna you are getting to get the cost per ounce.
$0.90/5 = $0.18 per ounce
$2.40/12 = $0.20 per ounce
Since the 5-ounce can of tuna has a cheaper unit rate price, meaning you are getting a better value, makes this the best option. I hope this was helpful and have a great day! :)

HELP PLEASE!! An artist is drawing three large circles on the ground with diameters of 6m, 10m, and 13m. Identify the area of each circle rounded to the nearest tenth of a meter.
Answer:
[tex]A1=28.3\ m^{2}[/tex],[tex]A2=78.5\ m^{2}[/tex],[tex]A3=132.7\ m^{2}[/tex]
Step-by-step explanation:
we know that
The area of a circle is equal to
[tex]A=\pi r^{2}[/tex]
Part 1) Find the area of the circle with diameter 6 m
we have
[tex]r=6/2=3\ m[/tex] -----> the radius is half the diameter
substitute the values
[tex]A1=(3.14)(3)^{2}=28.3\ m^{2}[/tex]
Part 2) Find the area of the circle with diameter 10 m
we have
[tex]r=10/2=5\ m[/tex] -----> the radius is half the diameter
substitute the values
[tex]A2=(3.14)(5)^{2}=78.5\ m^{2}[/tex]
Part 3) Find the area of the circle with diameter 13 m
we have
[tex]r=13/2=6.5\ m[/tex] -----> the radius is half the diameter
substitute the values
[tex]A3=(3.14)(6.5)^{2}=132.7\ m^{2}[/tex]
The areas of the circles with diameters 6m, 10m, and 13m are approximately A₁=28.3 m², A₂ =78.5 m², and A₃=132.7 m², respectively.
To determine the area of each circle, we use the formula for the area of a circle: A = πr², where A is the area and r is the radius of the circle. First, we need to find the radii of the circles, which are half of their diameters.
For the circle with a diameter of 6 meters, the radius is 3 meters. The area is then π(3)² = 28.3 square meters (rounded to the nearest tenth).For the circle with a diameter of 10 meters, the radius is 5 meters. The area is then π(5)² = 78.5 square meters (rounded to the nearest tenth).For the circle with a diameter of 13 meters, the radius is 6.5 meters. The area is then π(6.5)² = 132.7 square meters (rounded to the nearest tenth).Therefore, the areas of the circles are approximately 28.3 m², 78.5 m², and 132.7 m² respectively.

The first step is to add 4.2 on both sides of the equation;
[tex]1.2*10^{4x}=14.1[/tex]
The next step will be to divide both sides of the equation by 1.2;
[tex]10^{4x}=11.75[/tex]
Next we take natural logs on both sides of the equation;
[tex](4x)ln10=ln11.75[/tex]
Finally, we divide both sides by 4*ln10 and simplify to determine x;
[tex]x=\frac{ln11.75}{4ln10}=0.27[/tex]

rearrange the x terms to the left and constant to the right
3(x-1)² = 162
(x-1)² = 162/3
(x-1)² = 54
Take square root on both sides
√(x-1)² = √54
x - 1 = ±3√6
x = ±3√6 + 1
So we have two values for x
x = 3√6 + 1 OR x = -3√6 + 1
Answer:
b.x = 1+3√6, 1-3√6
Step-by-step explanation:
We have given a quadratic equation.
3(x-1)²-162 = 0
We have to find the solution of given equation by taking the square root of both sides.
Simplifying above equation, we have
3(x-1)² = 162
Dividing above equation by 3, we have
(x-1)² = 54
Taking square root to both sides of equation, we have
x-1 = ±√54
x = ±√54+1
x = ±√(9×6)+1
x = ±3√6+1
x = 1+3√6, 1-3√6 which is the solution of given equation.

take each equation and put number of miles in that , calculate cost and compare the table.
for example
taking first equation
c = 0.15m + 5.75
noe.from table take m = 10, after putting this we should get cost equal to 5.75 as mentioned in table.
c = 0.15×10 + 5.75 = 7.25 ≠ 5.75
so ignore this and take next equation
c = 0.15m + 4.25
m =10
c = 0.15×10 + 4.25 = 5.75
which matches with our table. putting other values of m from table gives us the right cost mentioned in table . so answer is option B
you can verify that no other equation satisfies the table data.

An architect is designing a ramp that allows handicapped persons to get to a door's level that is 12 feet off the ground. What is the maximum angle of elevation for the rap, rounded to the nearest hundredth of a degree? What is the shortest possible length of the ramp, rounded to the nearest tenth of a foot? The ramp can not have an incline surpassing a ratio of 1:12.
Answer:
4.780 °
144''
Step-by-step explanation:
Given that,
door's level is 12 feet off the ground
the ramp can not have an incline surpassing a ratio of 1:12
An incline surpassing a ratio of 1:12 , means that every 1" of vertical rise requires at least 12" of ramp length
So,
1' rise = 12' length
12' = 12'x12
= 144''
now we know the length and height of ramp so we can use trigonometry identities to find the angle
sinФ = height / length
sinФ = 12 / 144
sinФ = sin^-1(12/144)
Ф = 4.780 °
What is the value of y in the solution to the system of equations?

8
Final answer:
After solving the given system of equations, the value of y is determined to be 6.4, but this answer does not match any of the provided choices. There appears to be an error in the options given or the original equations.
Explanation:
To find the value of y in the solution to the system of equations, we first need to solve the system. We have two equations:
x + y = 1
2x – 3y = –30
From the first equation, we can express x in terms of y:
x = 1 - y
Next, we substitute this expression for x into the second equation:
2(1 - y) - 3y = -30
Expanding this equation:
2 - 2y - 3y = -30
Combining like terms:
-5y = -32
Divide both sides by -5 to find the value of y:
y = 32 / 5
Now, we can see that none of the options provided in the question (-8, -3, 3, 8) match the correct value we found, which is 6.4. It seems there might be an error in the options provided. However, if the question intended for y to be an integer, then we should re-examine the arithmetic or consider that there might be a typo in the original equations or options given.
which pair of numbers, if included in this set, would NOT change the median?
{ 28, 27, 35, 47, 43, 37}
a- 35, 50
b- 37, 48
c- 36, 42
d- 24, 31
The median of a set is defined as the middle element of the sorted set.
So, the only way to add two elements without changing the median is to add an element before it, and one element after it.
Think about it: if you are the middle element in a queue, and we add something before you and something after you, you're still in the middle:
[tex] \{2,\ 3,\ 4\} \mapsto \{1,\ 2,\ 3,\ 4,\ 5\}[/tex]
In both cases, the middle element is 3.
If, instead, we add two elements before 3,
[tex] \{2,\ 3,\ 4\} \mapsto \{0,\ 1,\ 2,\ 3,\ 4\}[/tex]
the median has changed, and similarly if we add two elements after 3
[tex] \{2,\ 3,\ 4\} \mapsto \{2,\ 3,\ 4,\ 5,\ 6\}[/tex]
the median has changed again.
So, if we sort our set, we have
[tex]\{27,\ 28,\ 35,\ 37,\ 43,\ 47\}[/tex]
And the middle elements are 35 and 37. The only option that adds something bigger than then and something smaller than them is option a.
Solve for x. 8x/7 + 9 = 30
Answer:18.375
Step-by-step explanation:8x/7+9=30
We simplify the equation to the form, which is simple to understand
8x/7+9=30
Simplifying:
+1.14285714286x+9=30
We move all terms containing x to the left and all other terms to the right.
+1.14285714286x=+30-9
We simplify left and right side of the equation.
+1.14285714286x=+21
We divide both sides of the equation by 1.14285714286 to get x.
x=18.375
