The value 2,000 is decreased to 100. What is the percent decrease?
percent decrease =
Answer:
95 percent decrease
Step-by-step explanation:
2000/100=5 percent. This means that for every 100 decrease, the percent decrease is 5 percent.
Since it decreased by 1900, 19 hundreds x 5 =95 percent decrease
If you liked my answer, a brainliest would much be appreciated! Thanks!
The value of 2,000 is decreased to 100. Then the percentage of decrease will be 95%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The value of 2,000 is decreased to 100. Then the percentage of decrease will be given as,
P = [(2,000 - 100) / 2,000] x 100
Simplify the expression, then we have
P = [(2,000 - 100) / 2,000] x 100
P = [1,900 / 2,000] x 100
P = 0.95 x 100
P = 95%
The value of 2,000 is decreased to 100. Then the percentage of decrease will be 95%.

Answer:
4x-15+6x-35=180
Step-by-step explanation:
4x−15+6x−35=180
Step 1: Simplify both sides of the equation.
4x−15+6x−35=180
4x+−15+6x+−35=180
(4x+6x)+(−15+−35)=180(Combine Like Terms)
10x+−50=180
10x−50=180
Step 2: Add 50 to both sides.
10x−50+50=180+50
10x=230
Step 3: Divide both sides by 10.
10x/10=230/10

An ice cream cone measures 4 in across the opening of the cone. Two hemisphere shaped scoops of ice cream, which have diameters of 4in, are placed on top of the cone. As the ice cream melts, it begins to fill the ice cream cone. How deep must the cone be so that the melted ice cream will fill the cone exactly to the top without overflowing?
Answer:
8 inches
Step-by-step explanation:
The volume of a hemisphere is half the volume of a sphere.
Therefore, the sum of the volumes of the two hemisphere-shaped scoops of ice cream (with diameters of 4 inches), is equal to the volume of a sphere with diameter of 4 inches.
If the melted ice cream fills the cone exactly to the top without overflowing, the volume of the cone with diameter of 4 inches must be equal to the volume of a sphere with diameter of 4 inches.
As the diameter of a circle is twice its radius, then the radius of the sphere and cone is r = 2 inches.
The formulas for the volume of a cone and the volume of a sphere are:
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex] [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a sphere}\\\\$V=\dfrac{4}{3} \pi r^3$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius.\\\\\end{minipage}}[/tex]
The depth of the cone is its height.
Therefore, to calculate how deep the cone must be so that the melted ice cream will fill the cone exactly to the top without overflowing, set the two equations equal to each other, substitute r = 2, and solve for h (the depth of the cone).
[tex]\begin{aligned}\textsf{Volume of a cone}&=\textsf{Volume of a sphere}\\\\\dfrac{1}{3} \pi (2)^2 h & = \dfrac{4}{3} \pi (2)^3\\\\\dfrac{1}{3} \pi \cdot 4 h & = \dfrac{4}{3} \pi \cdot 8\\\\\dfrac{4}{3} \pi h& = \dfrac{32}{3} \pi \\\\\dfrac{4}{3} h& = \dfrac{32}{3} \\\\4 h& = 32 \\\\h&=\dfrac{32}{4}\\\\h&=8\; \sf inches\end{aligned}[/tex]
Therefore, the depth of the cone must be 8 inches.
The cone must be at least 8 inches deep in order for the melted ice cream to fill the cone exactly to the top without overflowing.
1. The opening of the ice cream cone has a diameter of 4 inches. This means that the radius of the cone's opening is 4/2 = 2 inches.
2. The two hemisphere-shaped scoops of ice cream have diameters of 4 inches each. This means that the radius of each scoop is 4/2 = 2 inches.
3. When the ice cream melts, it will take up the space between the scoops and fill the cone. In order for the melted ice cream to fill the cone exactly to the top without overflowing, the depth of the cone must be equal to the combined height of the two ice cream scoops.
4. The height of each hemisphere-shaped scoop can be calculated using the formula for the volume of a sphere, which is (4/3)πr³, where r is the radius.
- For each scoop, the radius is 2 inches, so the height of each scoop is (4/3)π(2)³ = (4/3)π(8) = (32/3)π.
5. Since there are two scoops, the combined height of the two scoops is 2 * (32/3)π = (64/3)π.
6. Therefore, the cone must be at least (64/3)π inches deep in order for the melted ice cream to fill the cone exactly to the top without overflowing. This is approximately equal to 67.03 inches.

Anthony bought a rug for his office. He made a scale drawing of the office using a scale of 1 in = 4 ft.
What is the area of the office floor not covered by the rug?
Answer:
Area of the floor not covered = 240ft²
Step-by-step explanation:
Find the diagram attached
The area of the floor not covered = area of the office floor - area of the rug covered
Area of the office floor = 7in×5in = 35in²
Area of the rug = 5in×4in = 20in²
Area of the floor not covered = 35in²-20in² = 15in²
Since 1in = 4ft
1in² = 16ft²
Given the area of the floor not covered to be 15in²
In square feet will be 16×15 = 240ft²

Answer:
5n - 3
Step-by-step explanation:
3 less then 5 time a number (n)
first of all we know were subtracting
-3
and were multiplying 5 and a number
5n
in my mind the one thing that makes sense is
5n - 3
but the problem can be switched
-3 + 5n
[tex]\boxed{5n-3}[/tex]
Answer: To interpret this expression, we first identify that "3 less than 5" means that we are subtracting 3 from 5. Our equation looks like this:
5 - 3
Now, we add the variable. We would put n in front of 5, because the problem says "5 times a number n." It now looks like:
5n - 3

Deciding whether to issue a loan to an applicant based on demographic and financial data (with reference to a database of similar data on prior customers):
This task would likely be framed as a supervised learning problem. The goal is to predict whether to approve or reject a loan application based on the given data. Hence, it can be considered a classification problem.
In an online bookstore, making recommendations to customers concerning additional items to buy based on the buying patterns in prior transactions:
This task would also be framed as a supervised learning problem. The goal is to recommend additional items to customers based on their buying patterns. It can be approached as a recommendation system using collaborative filtering techniques, which involve predicting customer preferences. This can be considered a classification problem.
