Answer:

x = 17.2 oz of substance A and C

x = 3.7 oz of substance B

Step-by-step explanation:

This is a word problem in mathematical optimization, which involves finding the values that maximize or minimize some objective function. To solve this problem, we need to find the optimal number of ounces of each substance to provide 100% of the required nutrition.

Let x be the number of ounces of substance A and C. Then the amount of substance B is 1 1/5 times either of these, or 1 1/5 x.

Since each ounce of substance A supplies 3% of the nutrition, the total contribution from A is 3x%. Similarly, the total contribution from B is 10 * 1 1/5 x = 11 x/5% and from C is 15x%.

The objective is to find x such that the total contribution from all three substances is 100%, or 3x + 11 x/5 + 15x = 100.

Solving for x, we have

29x/5 = 100

x = 100 * 5 / 29 = 17.24 oz

So, 17.24 oz of substance A and C, and 1 1/5 * 17.24 oz = 3.65 oz of substance B should be in the meal. Rounding to the nearest tenth, we have:

x = 17.2 oz of substance A and C

x = 3.7 oz of substance B

by trigonometry the magnitude of the force P so that the resultant force exerted on the stake is vertical. The magnitude of the force is 196.6 N.

When a force system acts on an item, the difference between the forces is referred to as the Resultant force. When an item is under the influence of two or more forces, the combined force may be calculated by adding up the separate forces. The forces in all directions will be the same for all the forces if they are all acting in the same direction. The SI unit for resultant force is the Newton.

Given that,

α = 30°

Using the triangle rule, and the law of sines:

120 N / Sin 30° = P / Sin 25°

or, P =  (Sin 25° /  Sin 30°) × 120

or, P = 101.428 N

or, P = 101.4 N

and also, θ = 180 - 25 - 30

θ = 125°

the value of resultant is:

120 N / Sin 30° = R / Sin 25°

Answer:

0.5236 radians per minute

or

0.00872665 radians per second

Step-by-step explanation:

Let's first define angular speed

Angular speed is the rate at which an object changes it angles which we measure in radians in a given time. Angular speed has a magnitude (a value only whereas velocity is a vector with speed and direction)

The angular speed, ω of an object is given by the formula
ω = θ/t

where  θ is the angle in radians
1 full revolution is 360° or 2π radians

t = time taken for completing θ radians of rotation

We are given that the Ferris wheel completes 1 full revolution in 12 minutes

1 full revolution = 2π radians

t = 12 minutes

Angular speed = ω = θ/t =  2π/12 radians/minute

ω = 0.5236 radians per minute

or in radians per second

ω = 0.5236/60 = 0.00872665 radians per second

The line's equation is y = 3x - 3 with the z-intercept (-1, 0) and the y-intercept (0, -3).

Two triangles having two pairs of congruent sides and a pair of congruent angles do not necessarily meet the SAS congruence criterion, therefore Angie is incorrect.

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

An included angle is found between two sides that are under consideration.

In the image, the triangles are congruent to each other by the Side-Angle-Side Congruence Theorem (SAS).

Thus, two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.

Answer: $ 5.90 is the the cost of 2 panes of glass

In order to solve this we must divide the number of panes, by the cost spent on the panes. 20.65 divided by 7 is 2.95. This means that each pane is $ 2.95. If there are two panes that were also broken, we have to add 2.95 twice, which is $5.90. This means that the nursey owner must spend another $5.90 on two panes.

Step-by-step explanation:

(n+1)! = (n+1)n(n-1)(n-2)...×3×2

16n! = 16n(n-1)(n-2)...×3×2

16(n-1)! = 16(n-1)(n-2)...×3×2

we can now divide both sides by (n-1)! and get

(n+1)n = 16n + 16

n² + n = 16n + 16

n² - 15n - 16 = 0

1×n² - 15n - 16 = 0

we try to bring this into a form

(n + a)(n - b)

one factor has to contain "-", because we have "-16".

and because -15 = 1 - 16, we see that

a = 1

b = 16

n² - 15n - 16 = (n + 1)(n - 16)

and that is 0, when at least one of the factors is 0, because 0×... = 0.

so, the solutions are

n = -1

n = 16

n = -1 does not make any sense for n!

so, n = 16 is the solution.

Answer:

706.86

Step-by-step explanation:

The area of the sign will be found with the formula πr^2

r = 15 since the radius is half of the diameter

π(15)^2 = 706.86

Answer:

707 square inches.

Step-by-step explanation:

The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. The diameter of a circle is equal to twice the radius, so we can find the radius by dividing the diameter by 2.

In this case, the diameter of the circular railroad-crossing sign is 30 inches, so the radius is 30/2 = 15 inches.

So, the area of the sign is A = π * 15^2 = π * 225 = 706.86 square inches.

Rounding to the nearest whole number, the area of the sign is 707 square inches.

A correct answer is option (B) 7.78%. so, the interest rate is  7.78% being charged in her lease.

What is the interest rate?

Interest rate is the amount charged over and above the principal amount by the lender from the borrower. In terms of the receiver, a person who deposits money to any bank or financial institution also earns additional income considering the time value of money, termed as interest received by the depositor.

The interest rate in a lease can be calculated using the money factor, which is essentially a type of interest rate used in auto leasing.

To calculate the interest rate from the money factor, multiply the money factor by 2400.

In this case, the money factor is 0.00324, so the interest rate would be:

0.00324 * 2400 = 7.776%

Therefore, the correct answer is option (B) 7.78%. so, the interest rate is  7.78% being charged in her lease.

A correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

The money factor, which is essentially a sort of interest rate utilized in auto leasing, can be used to compute the interest rate in a lease.

By multiplying it by 2400, you can determine the interest rate from the money element.

Given that the money component in this situation is 0.00324, the interest rate would be:

The result of three consecutive conversions from an interest rate to a money factor is 2400 (1/2 × 1/12 × 1/100). 6/2400 = 0.0025 money factor, which can be multiplied by the entire amount borrowed to see how much the monthly interest would be roughly.

(1/2 × 1/12 × 1/100). 6/2400 = 0.0025

0.00324 × 2400 = 7.776%

The solution is, EF = 4√3

Area of a rectangle (A) is the product of its length (l) and width (w).

A= l. w

here, we have,

In rectangle ABCD, AB = 6, BC = 8, and DE = DF.

ΔDEF is one-fourth the area of rectangle ABCD.

We want to determine the length of EF.

First, we can find the area of the rectangle. Since the length AB and width BC measures 6 by 8, the area of the rectangle is:

A = 48 cm^2

The area of the triangle is 1/4 of this. Therefore:

A = 12 cm^2

The area of a triangle is half of its base times its height. The base and height of the triangle is DE and DF. Therefore:

12 = 1/2 * DF *DE

Since DE = DF:

24 = DF^2

Thus:

DF = 2√6 = DE

Since ABCD is a rectangle, ∠D is a right angle. Then by the Pythagorean Theorem:

DF^2 + DE^2 = EF^2

Therefore:

now, Squaring & Adding , we get,

FE^2 = 48

The completion of the equation to find w, the number of weeks until Ashely and Tanner have the same amount in their savings accounts is 25w + 450 = 40w + 200.

An equation is a mathematical statement claiming that two or more mathematical expressions are equivalent or equal.

Equations are depicted with the equation symbol (=) to show equality of the expressions.

                                       Ashely  Tanner

Savings                            $450    $200

Planned weekly deposits $25      $40

Let the number of weeks to save equal amounts = w

Ashely's total savings in w weeks = 25w + 450 ... Equation 1

Tanner's total savings in w weeks = 40w + 200 ... Equation 2

For the two friends to have an equal amount, Equation 1 must equal Equation 2:

25w + 450 = 40w + 200

Answer:

The equation of the proportional relationship can be written as y = (2/3)x.

Step-by-step explanation:

This equation is derived by using the fact that the slope of the relationship between x and y is 2/3. The slope of a line can be expressed as the ratio of the change in y to the change in x, which is represented by (delta y) / (delta x).

Since the slope is 2/3, the change in y for a unit change in x can be expressed as 2/3 * x. This relationship can then be written in terms of x and y by solving for y:

y = (2/3) * x.

In this equation, y is directly proportional to x with a constant of proportionality equal to 2/3.
