A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

While on vacation in Missouri, Sue's family stopped to see the world's largest ball of nylon twine.

Before they got there, Sue predicted the ball would weigh 6,000 pounds.

Her prediction was 50% less than the actual weight of the ball.

let, the ball's actual weight = x

now, 50% of x = x/2

ATQ, x/2 = 6,000 pounds.

so, x = 12000

Hence, The solution is, 12000 pound was the ball's actual weight.

The measurements of the figures that should be equal in order for the ratio of volumes between the volumes of the cone, sphere, and cylinder of 1:2:3 to be true is; The radius and the height

A ratio is a comparison between the magnitudes or measurements of items, expressing the number of times one item in the ratio is contained within another item in the ratio.

The formula for the volume of a cone, [tex]V_p[/tex] is, [tex]V_p[/tex] = (1/3)·π·r₁²·h₁

The formula for the volume of a sphere, [tex]V_s[/tex], is [tex]V_s[/tex] = (4/3)·π·r₂³

The formula for the volume of a cylinder, [tex]V_c[/tex], is [tex]V_c[/tex] = π·r₃²·h₃

The ratio of the volumes in the question is 1:2:3

Therefore; The volume of the sphere is twice the volume of the cone, and the volume of the cylinder is three times the volume of the cone, which indicates;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·h₁...(1)

π·r₃²·h₃ = 3 × (1/3)·π·r₁²·h₁...(2)

Equation (1) indicates that we have;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·h₁

Where, h₁ = 2·r₂, we get;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·(2·r₂) = (4/3)·π·r₁²·r₂

Therefore; r₁ = r₂, and the diameter of the sphere is equal to the height of the cone

The radius of the cone is equal to the radius of the sphere

Equation (2) indicates;

π·r₃²·h₃ = 3 × (1/3)·π·r₁²·h₁ = π·r₁²·h₁

Therefore;

r₃²·h₃ = r₁²·h₁

r₃ = r₁

h₃ = h₁

The radius of the cone = The radius of the cylinder

The height of the cone = The height of the cylinder

Answer: y = -5/6x - 23/6

(Read the explanation first to make sure it's correct)

Step-by-step explanation:

A parallel line means that it has the same slope as the equation:

5x + 6y = 11

Let's first convert this standard form equation into slope-intercept form:

y = -5/6x + 11/6

So that means that our new line also has a slope of:

-5/6

So far, for our new equation we have:

y = -5/6x + b

Next, let's plug in the values of our point to the equation:

-3 = 5/6 + b

So b = -23/6

So the equation in slope-intercept form is:

y = -5/6x - 23/6

The price of the pipette for company A and company B will be $480 and $420, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A research facility supervisor was keen on purchasing another pipette. Organization A was selling 2 pipettes for £300 not as much as Organization B was selling 3 pipettes for. For a solitary pipette, Organization A was more costly by £60 than Organization B.

Let 'x' be the price of the pipette of company A and 'y' be the price of the pipette of company B. Then the equations are given as,

2x = 3y - 300         ...1

x = y + 60                 ...2

From equations 1 and 2, then we have

2(y + 60) = 3y - 300

2y + 120 = 3y - 300

y = 420

Then the value of x is given as,

x = 420 + 60

x = 480

The price of the pipette for company A and company B will be $480 and $420, respectively.

Answer:

y = 3/4x - 1

Step-by-step explanation:

4x + 3y = 7

3y = -4x + 7

y = -4/3x + 7/3

The slope of the given line is -4/3 so the slope of a line perpendicular to it is 3/4 (negative reciprocal).

y = 3/4x + b

Substitute x = 4 and y = 2:

2 = 3/4(4) + b

2 = 3 + b

b = -1

Thus the final equation is y = 3/4x - 1

Answer:

Step-by-step explanation:

You want to know if a function can have the characteristic that the limit at a point does not exist, but the function is defined at that point.

A function has no limit at a point if the limit from the left is different from the limit approaching from the right.

Consider the sign function ...

  [tex]\text{sign}(x)=\begin{cases}-1,&x < 0\\0,&x=0\\1,&x > 0\end{cases}[/tex]

The left limit as x → 0 is -1; the right limit as x → 0 is +1, so the limit as x → 0 "does not exist." However, the function is defined at x=0.

The function is defined everywhere, but the limit as x→0 does not exist.

The distance from the lighthouse is 64 ft and the distance from Maya to the lighthouse is 56 ft

From the question, we have the following parameters that can be used in our computation:

Height of lighthouse = 48 ft

Height of Maya = 6 ft

Using the above parameters and the attached figure, we have the following equivalent ratio

48 : x = 6 : 8

Multiply the second ratio by 8

So, we have

48 : x = 48 : 64

This means that

x = 64

From the figure, we have

y + 8 = x

Recall that

x = 64

So, we have

y + 8 = 64

Evaluate

y = 56

Hence, the distance is 56 ft

Answer:

x = 4

Step-by-step explanation:

2x + 1 ≥ 0

2x ≥ -1

2/2 x ≥ -1/2

x ≥ -1/2

2x + 1 = 3²

2x = 9 - 1

2x = 8

2/2 x = 8/2

x = 4

The factored form of the polynomial x + 9x + 20 is (x + 4)(x + 5). To obtain this form, we can use the factoring method known as "FOIL," which stands for "First, Outer, Inner, Last." This method involves multiplying the first terms, the outer terms, the inner terms, and the last terms of the two factors to obtain the original polynomial.

In this case, if we let the factors be (x + 4) and (x + 5), we can use FOIL to multiply them and obtain the following:

(x + 4)(x + 5) = (x * x) + (4 * x) + (x * 5) + (4 * 5)

This simplifies to:

(x + 4)(x + 5) = x^2 + 9x + 20

As we can see, the result is the original polynomial. Therefore, the factored form of x + 9x + 20 is (x + 4)(x + 5)

The value of the factored form of the polynomial are,

⇒ (x + 4) (x + 5)

An algebraic equation with the second degree of the variable is called an Quadratic equation.

Given that;

The polynomial are,

⇒ x² + 9x + 20

Now, We can simplify as;

⇒ x² + 9x + 20

⇒ x² + 5x + 4x + 20

⇒ x (x + 5) + 4 (x + 5)

⇒ (x + 4) (x + 5)

Thus, The value of the factored form of the polynomial are,

⇒ (x + 4) (x + 5)

The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.

Clark reportedly placed $5000 at a constant 3.8% interest rate when he was 18 years old.

Using the compound interest calculation, we can calculate how much Clark will make when he turns 22.

A= Amount after T years.

P= Principal amount.

e= Mathematical constant e.

r= Interest rate (in decimal form).

T=  Time in years.
