Answer:

180 cars

Step-by-step explanation:

The group washes 12 cars in 1 hour, and in 2 hours they can wash 24. Therefore, if we multiply 12 by 15, we get 180.

Answer:

slope = -3

y-intercept = (0,7)

Yes -20 degrees and 340 degrees are co-terminal angles

are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330°.

The coterminal angles can be positive or negative. To find the coterminal angles, simply add or subtract 360 degrees as many times as needed from the reference angle. All of these angles are coterminal angles.

co-terminal angles are found by adding or subtracting 360° to the angles.

for example the co-terminal angles of -10° = -10° + 360 = 350°

Similarly The co-terminal angles of -20 = -20+360 = 340°

therefore the -20 and 340 are co-terminal angles

Answer:

b. interaction effect

Step-by-step explanation:

In a regression model, the interaction effect is present when a predictor variable changes the effect of another predictor variable on the outcome.

In a regression model, the interaction effect exists when one predictor variable impacts the outcome of another predictor variable differently than when examined individually. It refers to the interaction between two or more predictor variables and their influencers on an outcome or response variable. For example, in a regression model, studying and having a quiet place may individually contribute to a better score on a test, but perhaps studying in a quiet place provides a significantly better effect than the sum of those two effects separately. This would be considered an interaction effect.

The statement made by Lincoln in the movie "Lincoln" refers to a mathematical principle known as Euclid's first common notion. This notion can be seen as an example of both a postulate and a theorem.

In the statement, Lincoln says, "Things which are equal to the same things are equal to each other." This is a fundamental idea in mathematics that is often referred to as the transitive property of equality. The transitive property states that if a = b and b = c, then a = c. In other words, if two things are both equal to a third thing, then they must be equal to each other.

In terms of Euclid's first common notion being a postulate, a postulate is a statement that is accepted without proof. It is a basic assumption or starting point from which other mathematical truths can be derived. Euclid's first common notion is considered a postulate because it is not proven or derived from any other statements or principles. It is simply accepted as true. So, in summary, Euclid's first common notion, as stated by Lincoln in the movie, can be seen as both a postulate and a theorem. It serves as a fundamental assumption in mathematics, and it can also be proven using other accepted principles.

Answer:

$2,800 and $6,400

Step-by-step explanation:

Aquí, sabemos que hay un 20% de descuento en compras.

Entonces, para una persona que compró cosas por valor de $ 3,500, el monto que debe pagar será; 20/100 * 3500 = $ 700

Entonces, la cantidad a pagar = 3500-700 = $ 2,800

Para la persona que compró $ 8000, monto a pagar = 20/100 * 8,000 = $ 1,600

Cantidad a pagar = 8000-1600 = 6400

Answer:

1.

\(C.\\sin(N)=\frac{\sqrt{3} }{2}\)

2.

\(x=82.1\)

3.

x = 18°

Step-by-step explanation:

1. The sine ratio is sin(θ) = opposite/hypotenuse, where θ is the reference angle.  When N is the reference angle, we see that side OP with a measure of 5√3 units is the opposite side and side NP with a measure of 10 units is the hypotenuse.

Thus, we can find plug everything into the sine ratio and simplify:

\(sin(N)=\frac{5\sqrt{3} }{10} \\\\sin(N)=\frac{\sqrt{3} }{2}\)

2. We can use the tangent ratio to solve for x, which is tan (θ) = opposite/adjacent.  If we allow the 75° to be our reference angle, we see that the side measuring x units is the opposite side and the side measuring 22 units is the adjacent side.  Thus, we can plug everything into the ratio and solve for x or the measure of the opposite side:

\(tan(75)=\frac{x}{22}\\ \\22*tan(75)=x\\\\82.10511777=x\\\\82.1=x\)

3. Since we're now solving for an angle, we must using inverse trigonometry.  We can use the inverse of the tangent ratio, whose equation is tan^-1 (opposite/adjacent) = θ.  We see that when the x° is the reference angle, the side measuring 11 units is the opposite and the side measuring 33 units is the adjacent side.  Now we can do the inverse trig to find the measure of x:

\(tan^-^1(\frac{11}{33})=x\\ 18.43494882=x\\18=x\)

The sentence "If it is a dog (d), it has fleas (f)" can be represented in symbolic form as d → f.

In symbolic logic, we represent the components of a sentence using letters or symbols. In this case, the given sentence has two components: "it is a dog" and "it has fleas." To represent these components, we assign the letter 'd' to "it is a dog" and the letter 'f' to "it has fleas."

The sentence "If it is a dog, it has fleas" implies a conditional relationship between the two components. It states that if something is a dog (d), then it has fleas (f). This can be symbolically represented as d → f, where the arrow (→) denotes the conditional relationship.

The given sentence, "If it is a dog (d), it has fleas (f)," can be represented in symbolic form as d → f. The arrow (→) in symbolic logic represents the conditional relationship. It indicates that if something is a dog (d), then it has fleas (f). In this symbolic representation, 'd' stands for "it is a dog," and 'f' represents "it has fleas."

The sentence is a conditional statement because it presents a hypothetical relationship between the two components. The truth value of the sentence depends on whether the antecedent (d) is true or false. If something is indeed a dog, then it implies that it has fleas. However, if it is not a dog, the statement does not make any specific claim about fleas.

The statement is sometimes true. It depends on the relationship between the radius of the cone, the height of the cone, and the height of the prism.

The volume of a cone is given by the formula\(V_{cone} = (1/3)\pi r^2h\), where r is the radius of the cone and h is the height of the cone.

The volume of a prism is given by the formula\(V_{prism} = Bh\), where B is the base area of the prism and h is the height of the prism.

To determine if the statement is true, we need to compare the volumes of the cone and the prism.

If the base area of the cone is 3 times as great as the base area of the prism, it means that \(B_{cone} = 3B_{prism\).

Substituting these values into the volume formulas, we have \(V_{cone} = (1/3)\pi r^2h\) and \(V_{prism} = 3B_{prism} h\).

By comparing these formulas, we can see that the volume of the cone is indeed three times the volume of the prism, given the condition that \(B_{cone} = 3B_{prism\).

However, it is important to note that this relationship depends on the specific values of the radius and height of the cone and the height of the prism. If these values do not satisfy the condition \(B_{cone} = 3B_{prism\), then the statement would not hold true. Therefore, the statement is sometimes true, but it is not always true.

The (g·g)(t) of the function is (g·g)(t) = 16t - 15

A function is an expression, rule, or law that defines a relationship between an independent variable and a dependent variable

Since g(t) = -4t + 5

What (g·g)(t) means is that you should replace t with the value of g(t)  (i.e. -4t + 5) in the same equation. That is:

(g·g)(t) = g(g(t))

(g·g)(t) = -4(-4t + 5) + 5

(g·g)(t) = 16t - 20 + 5

It must be less effective than 100%. Any time you switch from one source of energy to another, especially if there is effort involved, there is a cost.

An enzyme is a protein that must retain its three-dimensional structure in order for it to function as a "lock and key." A little alteration to the enzyme structure might render it inoperative.

Denaturation of proteins is common. The protein's structure can change as a result of environmental factors including pH and temperature. An increase in temperature should hasten the process, but an excessive increase might harm the enzyme. Therefore, the situation in which there is no change to the enzyme structure would be the "ideal" one.

Step-by-step explanation:

1. 9 plants - 15 minutes

x plants - 75 minutes

Cross multiply

15x = 75 x 9

15x = 675

Divide both sides by 15

x = 675/15

x = 45 plants

45/85 x 100

= 52.94%

2. 90% of 180

= 90/100 x 180

= 162 plants

9 plants - 15 minutes

162 plants - x minutes

Cross multiply

9x = 162 x 15

9x = 2430

Divide both sides by 9

x = 2430/9

x = 270 minutes or 4 hours 30 minutes.

Step-by-step explanation:

To answer this, we need to plug in 3 as x in the equation f(x) = 5 + 4x².

That would look like this: f(3) = 5 + 4(3)²

f(3) = 5 + 4(3)²

f(3) = 5 + 36

f(5)=41
