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

Your answer would be option A.

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%.

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:

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:

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

The expression given involves various terms and operations. To simplify it completely, each term needs to be evaluated and simplified. The given expression includes square roots, fractions, and exponentiation.

a. To simplify 16a, we need more information about the variable 'a' to provide a specific answer.
b. The expression 18² can be simplified as 324, since 18 squared equals 324.
c. For 26/(6 - √2), we can rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator, which is 6 + √2. Simplifying this will result in (26(6 + √2))/(36 - 2) = (156 + 26√2)/34 = (78 + 13√2)/17.
d. SA²²¹ is an unknown term, so it cannot be simplified further without additional information.
e. The expression 5 - √(101) is already in its simplest form, since the square root cannot be simplified further.
f. The expression 12(2/2)(KE83) can be simplified as 12 * 1 * KE83 = 12KE83, assuming KE83 represents a known quantity.

a(n-3)+8=bn

Step 1: Add -bn to both sides.

an−3a+8+−bn=bn+−bn

an−bn−3a+8=0

Step 2: Add 3a to both sides.

an−bn−3a+8+3a=0+3a

an−bn+8=3a

Step 3: Add -8 to both sides.

an−bn+8+−8=3a+−8

an−bn=3a−8

n(a−b)=3a−8

Step 5: Divide both sides by a-b.

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.
