2 cups (into mL of water
Answer:
about 473 mL
Step-by-step explanation:
For liquid measure, there are 16 cups in a US gallon, which is exactly 231 cubic inches. Each cubic inch is exactly 2.54³ = 16.387064 cubic centimeters--the same number of mL.
So, the exact conversion from cups to mL is ...
1 cup = (231/16)(16.387064) mL = 236.5882365 mL
Multiplying this by 2 gives ...
2 cups = 473.176473 mL
For many purposes, the nearest mL is sufficiently accurate:
2 cups ≈ 473 mL

The graph shows the number of each kind of CD in Dante's collection. What is the probability that a randomly chosen CD will be country?
A.) 15%
B.) 20%
C.) 25%
D.) 30%
Photo of the graph is attached.
The probability of getting a country CD out of all the CDs is the number of country CDs divided by the total number of CDs in Dante's Collection.
The total number of CDs in Dante's collection is [tex]6+12+8+4+10=40[/tex].
The total number of country CDs is 12.
So our required probability is [tex]\frac{12}{40}= \frac{3}{10}[/tex].
In percentage this is 3 divided by 10, and then multiply by 100. We get 30%. Answer choice D is correct.
ANSWER: D
Answer: D.) 30%
Step-by-step explanation:
From the given pie chart, we have the number of country CD = 12
The total number of CD's=[tex]12+8+4+6+10=40[/tex]
Now, the probability that a randomly chosen CD will be country is given by :-
[tex]\text{P(country)}=\dfrac{\text{Number of country CD}}{\text{Total CDs}}\\\\=\dfrac{12}{40}=\dfrac{3}{10}=0.3[/tex]
In percent, [tex]0.3\times100=30\%[/tex]
Hence, the probability that a randomly chosen CD will be country is 30%.

Jaycee is writing a coordinate proof to show that the diagonals of a rectangle bisect each other. She starts by assigning coordinates to a rectangle. Then she uses these coordinates to write the coordinates of the midpoint of each diagonal. She finds that the midpoints of the diagonals have the same coordinates, so the diagonals must bisect each other.
What are the coordinates of the midpoint of the diagonals of the rectangle?
Enter expressions in the box for the coordinates of the midpoint.
(__,__)
The coordinates of the midpoint of the diagonals of a rectangle are found by averaging the x-coordinates and the y-coordinates of the endpoints of the diagonals. Because of the properties of a rectangle, the midpoint will be the same for both diagonals, confirming that the diagonals bisect each other. The midpoint's coordinates are ((x1+x2)/2, (y1+y2)/2).
Explanation:To find the coordinates of the midpoint of the diagonals of a rectangle, you must first know the coordinates of the rectangle's vertices. Suppose the rectangle has vertices at (x1, y1), (x1, y2), (x2, y1), and (x2, y2). Without loss of generality, let (x1, y1) and (x2, y2) be the endpoints of one diagonal and (x1, y2) and (x2, y1) be the endpoints of the other diagonal.
The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) can be found by averaging each of the x-coordinates and the y-coordinates of the endpoints. Thus, the midpoint M1 has coordinates ((x1+x2)/2, (y1+y2)/2). Similarly, the midpoint M2 for the other diagonal has coordinates ((x1+x2)/2, (y2+y1)/2). Because of the properties of a rectangle, these midpoints will be the same, confirming that the diagonals bisect each other.
Therefore, the coordinates of the midpoint of the diagonals of a rectangle are ((x1+x2)/2, (y1+y2)/2).

steve has 276 slides in carousels. each carousel holds 75 slides. how many carousels will be completely filled?
Steve can completely fill 3 carousels with his 276 slides as each carousel holds up to 75 slides.
Explanation:Based on the provided data, Steve has 276 slides and each carousel holds up to 75 slides. To find out how many carousels can be completely filled, we have to divide the total number of slides by the number that each carousel holds.
So, the calculation would be: 276 (total slides) divided by 75 (slides each carousel can hold).
276 ÷ 75 equals about 3.68. Since we cannot have a fraction of a carousel, we round the number down to the nearest whole number. Hence, Steve can completely fill 3 carousels with his slides.

find the volume of a regular hexahedron if one of the diagonals of its faces is 8 root 2 inches.
Final answer:
To find the volume of a regular hexahedron with a face diagonal of 8√2 inches, we first calculate the side length of the cube and then use it to determine the volume, resulting in a volume of 512 cubic inches.
Explanation:
The question asks to find the volume of a regular hexahedron (which is a cube), given the diagonal of one of its faces is 8√2 inches. Since we know the face of a hexahedron is a square, we can use the Pythagorean theorem to find the side of the square. The diagonal (d) of a square relates to its side (s) by the formula d = s√2. Therefore, we can solve for s: s = d / √2 = (8√2) / √2 = 8 inches. Now that we have the length of the side of the cube, we can compute the volume (V) using the formula V = s3. Substituting s = 8 inches, we calculate the volume as V = 83 = 512 cubic inches.

Why is it important to start saving for retirement decades before retirement age?
It is important to start saving for retirement decades before retirement age because of compound interest. When you start saving at a younger age, you have more time for your money to compound. In other words, you can start with a smaller amount of money and after 30 years of compounding, it can grow to a larger amount.
Compounding is the formula 1 + r to the n which means interest compounds into more interest over time.

Angle BDC = 37½°
CBD =
Answer:
[tex]\angle CBD=105^{\circ}[/tex]
Step-by-step explanation:
We have been given a diagram. We are asked to find the measure of angle CBD using given diagram.
We can see that in triangle ABD two angles measure 60 degree. Using angle sum property of triangle, we can find measure of triangle angle ADB as:
[tex]\angle A+\angle B+\angle D=180^{\circ}[/tex]
[tex]60^{\circ}+60^{\circ}+\angle D=180^{\circ}[/tex]
[tex]120^{\circ}+\angle D=180^{\circ}[/tex]
[tex]120^{\circ}-120^{\circ}+\angle D=180^{\circ}-120^{\circ}[/tex]
[tex]\angle D=60^{\circ}[/tex]
Since all angles of triangle ABD are equal, so it is an equilateral triangle and its all sides will have same measure.
[tex]AB=BD=AD[/tex]
We have been given segment AB is equal to segment BC. Now, we will get:
[tex]AB=BD=AD=BC[/tex]
In triangle BCD sides two sides (BD and BC) are equal, so it is an isosceles triangle.
We know that angles corresponding to equal sides of an isosceles triangle have equal measure, so measure of angle BDC will be equal to angle BCD.
[tex]\angle BDC=\angle BCD=37\frac{1}{2}^{\circ}[/tex]
Now, we will use angle property of triangle to find measure of angle CBD as:
[tex]\angle CBD+\angle BCD+\angle BDC=180^{\circ}[/tex]
[tex]\angle CBD+37\frac{1}{2}^{\circ}+37\frac{1}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{75}{2}^{\circ}+\frac{75}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{150}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{150}{2}^{\circ}-\frac{150}{2}^{\circ}=180^{\circ}-\frac{150}{2}^{\circ}[/tex]
[tex]\angle CBD=\frac{360}{2}^{\circ}-\frac{150}{2}^{\circ}[/tex]
[tex]\angle CBD=\frac{210}{2}^{\circ}[/tex]
[tex]\angle CBD=105^{\circ}[/tex]
Therefore, the measure of angle CBD is 105 degrees.

A ship sails due west from a harbor for 28 nautical miles. It then sails S68°W for another 17 nautical miles. How far is the ship from the harbor? (Round your answer to two decimal places.)
The ship is approximately 26.16 nautical miles from the harbor after following the described path.
To find the distance of the ship from the harbor after sailing due west for 28 nautical miles and then S68°W for another 17 nautical miles, we can use trigonometry to calculate the resultant displacement.
Let's break down the two legs of the journey:
1. Due west for 28 nautical miles is a straight line.
2. Sailing S68°W for 17 nautical miles forms an angle of 68° with the west direction.
Using trigonometry, we can find the horizontal and vertical components of the second leg:
Horizontal component = 17 * cos(68°)
Vertical component = 17 * sin(68°)
The total horizontal displacement from both legs is:
Horizontal displacement = 28 - (17 * cos(68°))
The total vertical displacement from both legs is:
Vertical displacement = 17 * sin(68°)
To find the distance from the harbor, we use the Pythagorean theorem:
Distance = √(Horizontal displacement² + Vertical displacement²)
Calculating:
Horizontal component = 17 * cos(68°) ≈ 6.93 nautical miles
Vertical component = 17 * sin(68°) ≈ 15.52 nautical miles
Horizontal displacement = 28 - (17 * cos(68°)) ≈ 21.07 nautical miles
Vertical displacement = 17 * sin(68°) ≈ 15.52 nautical miles
Distance = √(21.07² + 15.52²) ≈ √(443.9749 + 240.5504) ≈ √684.5253 ≈ 26.16 nautical miles
Therefore, the ship is approximately 26.16 nautical miles from the harbor after following the described path.

Two numbers are in a ratio of 3:6 their sum is 63 find the bigger number
To find the bigger number in the given ratio of 3:6 with a sum of 63, simplify the ratio to 1:2, assign a variable to the smaller number, and solve for the larger one. The bigger number is found to be 42.
Explanation:To find the bigger number when two numbers are in a ratio of 3:6 and their sum is 63, first simplify the ratio to its lowest terms. The ratio 3:6 simplifies to 1:2, since both terms can be divided by 3. Let's assign the variable x to the smaller number, which corresponds to the '1' part of the ratio. Therefore, the bigger number is twice the smaller one, so it can be represented as 2x.
The sum of the two numbers is given by the equation x + 2x = 63. Combine like terms to get 3x = 63. Dividing both sides by 3 gives x = 21. Since 2x represents the bigger number, we have 2x = 2 imes 21 = 42.
Hence, the bigger number in this ratio is 42.

Oscar needs to ship 14 rock cds, 12 classical cds, and 8 pop cds. he can only pack only one type of cd in each box and he must pack the same number of cds in each box. what is the greatest number of cds oscar can pack in each box?
Answer:
2
Step-by-step explanation:
Oscar needs to pack only one type of cd in each box and he must pack the same number of cd's in each box.
To solve this problem we would need to find the greatest common factor of the numbers given; the numbers that we have are 14, 12, 8.
First we are going to find the factors of all these three numbers:
14 = 1 x 2 x 7
12 = 1 x 2 x 2 x 3
8 = 1 x 2 x 2 x 2
The common factors of these three numbers are bolded:
14 = 1 x 2 x 7
12 = 1 x 2 x 2 x 3
8 = 1 x 2 x 2 x 2
We can see that the common factors are 1 and 2. The biggest of them is 2.
Therefore, the greatest number of cd's Oscar can pack in each box is 2
Since 2 is common to them all, hence the greatest number of cds oscar can pack in each box is 2 CDs
Given the number of cars needed to ship 14 rock CDs, 12 classical CDs, and 8 pop CDs
In order to get the greatest number of cds oscar can pack in each box, we will have to calculate the GCF of each value as shown:
The prime factors of each value is as shown
14 = 2 * 7
12 = 3 * 2 * 2
8 = 2 * 2 * 2
From the factors, we can see that only 2 is common to them all, hence the greatest number of CDs oscar can pack in each box is 2 CDs

If 600 cm2 of material is available to make a box with a square base and a closed top, find the maximum volume of the box in cubic centimeters. Answer to the nearest cubic centimeter without commas. For example, if the answer is 2,000 write 2000.
The maximum volume of the box is:
1000 cm³
Step-by-step explanation:Let x be the length of the square base
and h be the height(h) of the box.
As we know that the length(l) and width(w) of the box is same( since the base is in the shape of square)
As we know that the surface area of box is given by:
[tex]Surface\ Area=2(lw+wh+hl)\\\\\\i.e.\\\\\\Surface\ Area=2(x^2+xh+xh)\\\\\\Surface\ Area=2(x^2+2hx)[/tex]
We are given surface area of box=600 cm²
Hence,
[tex]2(x^2+2hx)=600\\\\i.e.\\\\x^2+2xh=300\\\\i.e.\\\\h=\dfrac{150}{x}-\dfrac{x}{2}[/tex]
The volume of box is given by:
[tex]Volume(V)=l\times w\times h\\\\\\Volume=x^2h\\\\\\Volume=x^2(\dfrac{150}{x}-\dfrac{x}{2})[/tex]
Hence,
[tex]V=150x-\dfrac{x^3}{2}[/tex]
Now, for maxima or minima we have derivative equal to zero.
[tex]i.e.\\\\\\\dfrac{dV}{dx}=0\\\\\\i.e.\\\\\dfrac{d}{dx}(150x-\dfrac{x^3}{2})=0\\\\\\i.e.\\\\\\150-\dfrac{3x^2}{2}=0\\\\\\i.e.\\\\\\150=\dfrac{3}{2}x^2\\\\\\x^2=100\\\\\\i.e.\\\\\\x=\pm 10[/tex]
Now,
[tex]\dfrac{d^2V}{dx^2}=\dfrac{-6x}{2}\\\\\\=-3x[/tex]
Now, as we know if for a given x
[tex]\dfrac{d^2V}{dx^2}<0[/tex]
then that x is a point of maxima.
Hence, when we put x=10 we get: [tex]\dfrac{d^2V}{dx^2}<0[/tex]
Hence, x=10 is a point of maxima
Also, the value of V at x=10 is:
[tex]V=150\times 10-\dfrac{(10)^3}{2}\\\\\\V=1500-\dfrac{1000}{2}\\\\\\V=1500-500\\\\V=1000\ cubic\ cm.[/tex]
Hence, the maximum volume of the box is:
1000 cm³
