Answer:

C. $4.50

Step-by-step explanation:

hello, there.

1) 2p + 3c = 17.50

2) 5p + 2c = 19.00

:

Solve equation 1 for p

:

p = (17.50 - 3c) / 2

:

Substitute for p in second equation

:

(5(17.50 - 3c) / 2) + 2c = 19.00

:

Multiply both sides of = by 2

:

(5(17.50 - 3c)) + 4c = 38.00

:

87.50 - 15c + 4c = 38.00

:

-11c = -49.50

:

c = 4.50

---------

Cashews are $4.50 per pound

--------------

:have a great day.

Answer:

C

Step-by-step explanation:

Let p represent the cost for one pound of peanuts and let c represent the cost for one pound of cashews.

Two pounds of peanuts and three pounds of cashews cost $17.50. So:

\(2p+3c=17.5\)

Five pounds of peanuts and two pounds of cashews cost $19.00. So:

\(5p+2c=19\)

This yields a system of equations.

We can solve this using elimination. We can multiply the first equation by -5, and the second by 2. Therefore:

\(-5(2p+3c)=-5(17.5)\)

Multiply:

\(-10p-15c=-87.5\)

And:

\(2(5p+2c)=2(19)\)

Multiply:

\(10p+4c=38\)

Now, we can add the two equations together:

\((-10p-15c)+(10p+4c)=(-87.5+38)\)

Combine like terms:

\(-11c=-49.5\)

Therefore:

\(c=4.5\)

So, a pound of cashews costs $4.50.

Our answer is C.

Notes:

To solve for the cost for peanuts, we can use the first (or second equation) again:

\(2p+3c=17.5\)

Substitute:

\(2p+3(4.5)=17.5\)

Solve for p:

\(2p+13.5=17.5\Rightarrow 2p=4\Rightarrow p=2\)

So, a pound of peanutes cost $2.00.

What you want to do first is to do the equation 5-7 which is -2 but there is an absolute value sign so 2.

-3|11 - 15|=-12

For this one it is a little more difficult but all you have to do is do the equation 11-15 which is -4 but there is an absoulte value sign so 4 you then multiply 4 by -3 which is -12 bam.

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

Option A is the correct answer.

We have,

To solve the equation 3x + 7 = 16 - 2x for x, we need to isolate the variable x on one side of the equation.

Let's solve it step by step:

Start with the original equation:

3x + 7 = 16 - 2x

- Add 2x to both sides of the equation to get rid of the -2x on the right side: 3x + 2x + 7 = 16 - 2x + 2x

- Simplifying, we have: 5x + 7 = 16

- Next, subtract 7 from both sides of the equation to isolate the term with x: 5x + 7 - 7 = 16 - 7

- Simplifying, we have: 5x = 9

- Finally, divide both sides of the equation by 5 to solve for x: (5x)/5 = 9/5

- Simplifying, we have: x = 9/5

Therefore,

The solution to the equation 3x + 7 = 16 - 2x is x = 9/5.

Step-by-step explanation:

The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits because they are ambiguous and can lead to confusion.

What are Limits?

In calculus, limits are used to describe the behavior of a function as the input values approach a certain value, usually infinity or a specific point. The concept of limits is essential in calculus and is used to define derivatives and integrals.

The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits because they are ambiguous and can lead to confusion. In the limit notation lim x→a, the variable x is approaching the value a from both sides, meaning it can approach a from either the left or the right.

The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ suggest that x is only approaching infinity or negative infinity from a specific direction, which is not the case in limit notation. Therefore, the notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits to avoid confusion and ensure clarity in mathematical expressions.

Multiple regression analysis is applied when analyzing the relationship between one dependent variable and two or more independent variables. The goal is to determine the extent to which the independent variables predict the dependent variable.

Multiple regression analysis is a statistical technique used to explore and quantify the relationship between a dependent variable and multiple independent variables. It allows researchers to examine how changes in one or more independent variables impact the dependent variable, while controlling for the effects of other variables. By estimating the coefficients for each independent variable, the analysis provides insights into the strength, direction, and significance of their relationships with the dependent variable. This method is commonly employed in various fields, such as economics, social sciences, and business, to understand complex relationships and make predictions based on the interplay of multiple factors.

The three points to plot for the equation 2y = 3x + 11 are (0, 5.5), (1, 7), and (-1, 4).

To graph the equation 2y = 3x + 11, we can choose any three points that satisfy the equation. Let's select three points and plot them on a coordinate plane:

Point 1:

Let's set x = 0 and solve for y:

2y = 3(0) + 11

2y = 0 + 11

2y = 11

y = 11/2 = 5.5

So, the first point is (0, 5.5).

Point 2:

Let's set x = 1 and solve for y:

2y = 3(1) + 11

2y = 3 + 11

2y = 14

y = 14/2 = 7

The second point is (1, 7).

Point 3:

Let's set x = -1 and solve for y:

2y = 3(-1) + 11

2y = -3 + 11

2y = 8

y = 8/2 = 4

The third point is (-1, 4).

Answer:

\(\frac{1}{4}\)

Step-by-step explanation:

let the number be x , then

\(\sqrt{x}\) = 2x ( square both sides )

x = (2x)² = 4x² ( subtract x from both sides )

4x² - x = 0 ( factor out x from each term )

x(4x - 1) = 0

Equate each factor to zero and solve for x

x = 0

4x - 1 = 0 ⇒ 4x = 1 ⇒ x = \(\frac{1}{4}\)

Assuming x > 0 then the number is \(\frac{1}{4}\)

As a check

\(\sqrt{\frac{1}{4} }\) = \(\frac{1}{2}\) and 2 × \(\frac{1}{4}\) = \(\frac{1}{2}\)

The required tension steel area for the reinforced concrete T-beam is approximately 3.82 square mm.

To calculate the required tension steel area for the reinforced concrete T-beam using the shortcut method,

Step 1: Calculate the effective depth of the T-beam.

d = Effective depth = Effective depth of the T-beam - Cover to tension steel

= 400 mm - (Tension steel diameter + Clear cover)

(Assuming a standard tension steel diameter and clear cover, let's say 25 mm and 40 mm, respectively)

= 400 mm - (25 mm + 40 mm)

= 335 mm

Step 2: Determine the lever arm (a) for the T-beam.

a = (d / 2) × (1 + (4 × Web Width) / Effective Flange Width)

= (335 mm / 2) × (1 + (4 ×300 mm) / 900 mm)

= 167.5 mm ×(1 + 1.33)

= 167.5 mm × 2.33

= 390.975 mm (approx. 391 mm)

Step 3: Calculate the moment of resistance (Mr) for the T-beam.

Mr = Factored moment / (0.87 ×fy × a)

= 750 KN-m / (0.87 × 345 MPa × 391 mm)

= 750,000 N-m / (0.87 ×345 × 10³ N/mm² × 391 mm)

= 0.00368 (approx.)

Step 4: Calculate the area of tension steel (Ast) required for the T-beam.

Ast = Mr / (0.87 × fy × (d - 0.42 × x))

= 0.00368 / (0.87 × 345 ×10³ ×(335 - 0.42 × 335))

= 0.00368 / (0.87 × 345 × 10³ × 335 × (1 - 0.42))

= 0.00368 / (0.87 × 345 ×10³ × 335 × 0.58)

= 0.00368 / (0.87 × 345 ×10³× 335 ×0.58)

The given fractions have equal value, so Liam is correct.

Equivalent fractions are defined as fractions that have different numerators and denominators but the same value. For example, 2/4 and 3/6 are equivalent fractions because they are both equal to 1/2. A fraction is part of a whole. Equivalent fractions represent the same part of a whole.  

Liam is claiming that the fraction -(5/12) is equivalent to 5/-12.

Thus, we can say that:

The fraction  -(5/12) can be described as the opposite of a positive number divided by a positive number. A positive number divided by a positive number always results in a positive quotient and its' opposite is always negative.

Answer:

B. consistent and dependent.

Step-by-step explanation:

y = -3x – 1

{

3x + y = -1

__________

This system is consistent and dependent because it has an infinite amount of solutions.

The easiest way to tell if the solutions are infinite is if the equations are equivalent.

As you can see, 3x + y = -1 is standard form, while y = -3x – 1 slope-intercept form.

We can tell that they are equivalent by converting the standard form equation to slope-intercept to see that they are equivalent.

All you need to do is subtract both sides by 3x to get the equation with respect to y so that it is slope intercept.

3x + y = -1 → 3x – 3x + y = -1 – 3x → y = -3x – 1.

[y = -3x – 1] = [y = -3x – 1].

Independent = one solution pair.

Inconsistent = no solution pair.

Consistent = at least one solution.

Dependent = infinite solutions.

The value of x which is the radius of the circle in the image above, is calculated to the nearest tenth as: x = 14.3.

The circle that is shown above has a radius whose length is represented as x. Since the segment that is drawn from the center of the circle intercepts the chord and is perpendicular to the chord, therefore, it bisects the chord into equal segments.

Thus, the perpendicular segment and half of the segment of  the chord will form a right triangle with the radius of the circle.

Therefore, using the Pythagorean Theorem, we have:

x = √(13² + 6²)

x = 14.3 [to the nearest tenth].
