The calculated value of each boy's share is shown below

Let's call the amount of oranges the third boy gets "x".

According to the problem, the second boy gets twice the amount of oranges as the third boy, so he gets 2x oranges.

And the first boy gets twice more oranges than the second boy, so he gets 2(2x) = 4x oranges.

So the total number of oranges is x + 2x + 4x = 7x, and we need to divide this equally among the three boys.

Therefore, the first boy gets 4/7 of the total oranges, which is 4x/3, the second boy gets 2/7 of the total oranges, which is 2x/3 and the third boy gets 1/7 of the total oranges, which is x/3.

The meaning of the y - intercept in the context of the problem of the snow level in Moose Wyoming is the level of snow at the beginning of the time period in question.

The y-intercept of the function y = 2x + 14 is the value of y when x = 0. Substituting x = 0 into the equation, we get:

y = 2(0) + 14

y = 14

Therefore, the y-intercept is 14.

In terms of the problem, this means that at midnight (when x = 0), there is already 14 inches of snow on the ground in Moose, Wyoming. The y-intercept represents the initial or starting value of the snow level function, which in this case is the amount of snow already on the ground at the start of the time period being modeled.

Radius simply means half of the diameter. In other words radius is the distance between the center of the circle to the outside of the circle

Here he formula for v is:

v = √(2gh)

What is meant by the term formula?

A formula is a mathematical relationship or rule that is expressed using symbols and mathematical operations. It is used to represent a relationship between quantities or to calculate a value based on given variables or inputs. Formulas are often used in various branches of mathematics, science, and engineering.

According to the given information

To change the subject of the formula mgh = (1/2)mv² to v, we need to isolate v on one side of the equation.

First, we can multiply both sides of the equation by 2 to eliminate the fraction:

2mgh = mv²

Next, we can divide both sides of the equation by m:

(2mgh) / m = v²

Simplifying the left side, we get:

2gh = v²

Finally, we can take the square root of both sides of the equation to solve for v:

v = √(2gh)

Therefore, the formula for v is:

v = √(2gh)

The density of the given metal is 19.3g/cm³ . Then, the correct answer to this given question is Option E.

The given mass of  the metal is 611 g  and it is kept in a elevated cylinder that contains 25.1 mL of water,
Now, let us increase the water level to 56.7 mL. The metal  volume can be evaluated by subtracting the initial volume  from the final volume of water released by the metal.

Hence,
Metal volume = final volume - initial volume
= 56.7 mL - 25.1 mL
= 31.6 mL

Therefore,
Density = Mass / Volume
= 611 g/31.6 mL
= 19.3 g/cm³

Answer:

$10,244.14 after 12 years

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

A = the final amount of the investment

P = the principal amount ($4200 in this case)

r = the annual interest rate (8% or 0.08 as a decimal)

n = the number of times the interest is compounded per year (once annually in this case)

t = the number of years the money is invested (12 years in this case)

Substituting the given values into the formula, we get:

A = 4200(1 + 0.08/1)^(1*12)

A = 4200(1.08)^12

A = 4200(2.44140625)

A = $10,244.14 (rounded to the nearest cent)

Answer:

a=60 (12*5=60)

b=7 (45/9=5 5+2=7)

c=62

d=25 (11*5=55 55-30=25)

The a is rational , b is irrational and product of a and b is rational.

The number a=0.444444444444 is rational

Because it can be expressed as the ratio of two integers.

a = 4/9

The number b=0.354355435554 is irrational

Because it cannot be expressed as the ratio of two integers.

It has an infinite non-repeating decimal expansion.

To determine whether the product of a and b is rational or irrational, we can simply multiply them together:

a × b = (4/9) × 0.354355435554

= 0.158919191574

This product is a rational number, because it can be expressed as the ratio of two integers.

Hence, a is rational , b is irrational and product of a and b is rational.

Step-by-step explanation:

Put '16' where 'x' is and compute

3/4 ( 16 ) + 7 = f(16) = 19

the average rate of change over the interval (-1, 2] in the given function is 1.17.all three functions have the same average rate of change over the interval [1, 2], which is 2

A function is a mathematical rule that takes an input and produces an output. The average rate of change of a function over an interval is the average amount the output changes per unit change in the input over that interval.

For the function f(x) = 2x + 3:

Let x1 = -1 and x2 = 2

f(x1) = 2(-1) + 3 = 1

f(x2) = 2(2) + 3 = 7

The average rate of change is:

[f(x2) - f(x1)] / [x2 - x1] = [7 - 1] / [2 - (-1)] = 6 / 3 = 2

Therefore, the average rate of change of f(x) over the interval (-1, 2] is 2.

For the function g(x) = x^2 - 1:

Let x1 = -1 and x2 = 2

g(x1) = (-1)^2 - 1 = 0

g(x2) = 2^2 - 1 = 3

The average rate of change is:

[g(x2) - g(x1)] / [x2 - x1] = [3 - 0] / [2 - (-1)] = 3 / 3 = 1

Therefore, the average rate of change of g(x) over the interval (-1, 2] is 1.

For the function h(x) = 2^x + 1:

Let x1 = -1 and x2 = 2

h(x1) = 2^(-1) + 1 = 1.5

h(x2) = 2^2 + 1 = 5

The average rate of change is:

[h(x2) - h(x1)] / [x2 - x1] = [5 - 1.5] / [2 - (-1)] = 3.5 / 3 = 1.17 (rounded to 2 decimal places)

Therefore, the average rate of change of h(x) over the interval (-1, 2] is approximately 1.17.

b)To determine which function has the greatest average rate of change over the interval [1, 2], we need to calculate the average rate of change for each function over that interval and compare the results.

Let's assume the functions are f(x), g(x), and h(x).

The average rate of change for f(x) over the interval [1, 2] is:

[f(2) - f(1)] / [2 - 1] = (2(2) + 3 - 2(1) - 3) / 1 = 2

The average rate of change for g(x) over the interval [1, 2] is:

[g(2) - g(1)] / [2 - 1] = (2^2 - 1 - 1^2 + 1) / 1 = 2

The average rate of change for h(x) over the interval [1, 2] is:

[h(2) - h(1)] / [2 - 1] = (2^2 + 1 - 2^1 - 1) / 1 = 2

Therefore, all three functions have the same average rate of change over the interval [1, 2], which is 2.

The percentage of pens that are blue =18%

Let's assume that r represents the red pens, b represents the blue pens and g represents the green pens.

From the statements we can observe that the blue appears in both ratio.

The ratios are,

r:b=5:9 and b:g=1:4

Consider ratio b:g,

b:g

= 1:4

= (1×9) : (4×9)

=9:36

i.e., b:g = 9:36 and r:b = 5:9

So, we can conclude that, b=9, g=36, r=5

so, the total number of pens would be,

n = b + g + r

n = 9 + 36 + 5

n = 50

Now we need to find the percentage of pens that are blue.

p = (9/50) × 100

The rate of change for the function f(x) is 9.5 over the interval.

How I calculated the rate of change for f(x):

f(2) = 12, f(6) = 50

slope = (50 - 12) / (6 - 2) = 9.5

The rate of change for the function g(x) is -2 over the interval.

How I calculated the rate of change for g(x):

g(2) = -10, g(6) = -18

slope = (-18 - (-10)) / (6 - 2) = -2

To find the rate of change for a function over an interval, we need to calculate the slope of the secant line that connects the two endpoints of the interval.

The slope of a line can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

For the quadratic function f(x) = (x + 1)² + 8, we can find the values of f(2) and f(6) by substituting x = 2 and x = 6 into the function:

f(2) = (2 + 1)² + 8 = 12

f(6) = (6 + 1)² + 8 = 50

Therefore, the rate of change for f(x) over the interval 2 ≤ x ≤ 6 is:

slope = (f(6) - f(2)) / (6 - 2) = (50 - 12) / 4 = 9.5

So the answer is: The rate of change for f(x) is 9.5 over the interval.

To find the rate of change for the linear function g(x) = -2x - 6, we can use the same formula:

g(2) = -2(2) - 6 = -10

g(6) = -2(6) - 6 = -18

Therefore, the rate of change for g(x) over the interval 2 ≤ x ≤ 6 is:

slope = (g(6) - g(2)) / (6 - 2) = (-18 - (-10)) / 4

slope = -2

So the answer is: The rate of change for g(x) is -2 over the interval.

LaTisha's calculation of the distance for the brake anchor placement is incorrect because she didn't take into account the height at which the cable is attached to the starting tree.

The bungee cord is attached 16 feet above the ground, which will also contribute to the length of the cable needed to reach the ending tree.

To correctly calculate the distance, we can use the Pythagorean theorem, considering the height (16 feet) and the length of the stretched bungee cord (24 feet + 18 feet = 42 feet). Let's denote the horizontal distance from the base of the ending tree to the brake anchor as 'd'. We have:

d² + 16² = 42²

Now, we can solve for d:

d² + 256 = 1764

d² = 1508
