The perimeter of this rectangle is 94, which is the smallest possible perimeter for a non-square rectangle with integer dimensions that has an area that is triple its perimeter.

Let's call the length of the rectangle "L" and the width of the rectangle "W". The area of the rectangle is then L * W, and the perimeter is 2 * (L + W).

According to the problem, the number of square units in the rectangle's area is triple the number of units in its perimeter:

L * W = 3 * (2 * (L + W))

Expanding the right side and solving for L:

L * W = 6L + 6W

L * W - 6L = 6W

L * (W - 6) = 6W

L = 6W / (W - 6)

Since L and W are both positive integers and L can't be equal to W (because the rectangle can't be a square), we know that W must be greater than 6. Let's try W = 7:

L = 6 * 7 / (7 - 6) = 6 * 7 = 42

This gives us a rectangle with dimensions 42 x 7, which satisfies the conditions of the problem.

The perimeter of this rectangle is 2 * (42 + 7) = 94, which is the smallest possible perimeter for a non-square rectangle with integer dimensions that has an area that is triple its perimeter.

Answer:

Step-by-step explanation:

To solve for x in the equation 3x + 2 = 11, we'll start by subtracting 2 from both sides:

3x + 2 - 2 = 11 - 2

Simplifying the left-hand side:

3x = 9

Finally, divide both sides of the equation by 3 to find x:

(3x) / 3 = 9 / 3

x = 3

We can quickly determine that the person has been moved by 10 miles by logical reasoning.

A mental process called logical reasoning seeks to reach a conclusion in a precise way.

By beginning with a set of premises and reasoning to a conclusion supported by these premises, it takes the shape of inferences or arguments.

Propositions, or true or false statements about the reality of a situation, are what the premises and the conclusion are.

They have a disagreement as a group.

In the sense that it seeks to develop correct arguments that any sane person would find persuasive, logical reasoning is norm-governed.

Logic is the primary academic field that studies logical reasoning.

So, using logical thinking, we can easily tell that the person is displaced by 10 miles.

The y-intercept of the line shown is (0,4).

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Answer:

88

Step-by-step explanation:

We can set up the proportion 8/1 = x/11. By cross-multiplying, we get that x = 88.

The number 56 when compared to 10 is the same as 28 compared to 5.

Option- C(56)

Let x be the number when compared to 10 is same as 28 compared to 5.

So, finding the value of x by comparing the ratios of the above stated values.

Therefore,

                    [tex]\frac{x}{10} = \frac{28}{5}[/tex]

So, Cross multiplying the above equation,

                      x × 5 = 28 × 10

                       5x = 280

                        x = [tex]\frac{280}{5}[/tex]

                        x = 56

So, 56 when compared to 10 bears the same ratio as 28 compared to 5.

Step-by-step explanation:

To find the velocity of the particle, we need to take the derivative of the position vector with respect to time.

r(θ) = (a + b * cos(θ)) * i + (b * sin(θ)) * j

d/dt[r(θ)] = d/dt[(a + b * cos(θ)) * i + (b * sin(θ)) * j]

d/dt[r(θ)] = (-b * sin(θ)) * i + (b * cos(θ)) * j

So there are ten different combinations of two pupils out of five when there are five kids in my class and I want to choose two to treat to lunch.

A combination in mathematics is a selection of elements from a set with distinct members, where the order of selection is irrelevant. A combination is a mathematical approach for determining the number of potential arrangements in a set of objects when the order of the selection is irrelevant. You can choose the components in any order in combinations. Permutations and combinations are often mistaken. A combination is a method of picking elements from a collection when the order of selection is irrelevant. Assume we have three integers P, Q, and R. Combination defines how many possibilities we may choose two numbers from each set.

Here,

To determine the number of ways to pick 2 students out of 5 to treat them to lunch, you can use the combination formula, which is given by nCr, where n is the number of items to choose from, r is the number of items to choose, and nCr is the number of combinations of n items taken r at a time. In this case, n = 5 and r = 2, so the number of ways to pick 2 students out of 5 is:

5C2 = 5! / (2! * (5 - 2)!) = 10

Answer:

(m,n) is (-2,2)

Step-by-step explanation:

Elimination means that we should rewrite one of the two equations as an expression of one of the variables isolated, and then use that definition isn the other equation.  It is also called "substitution."

Lets use the first equation and rewrite it so that the variable m is isolated:

3m-4n=-14

-4n = -3m-14

n = (3/4)m +(7/2)

Now use this definition of n in the second equation:

3m+2n=-2

3m+2((3/4)m +(7/2)) = -2

3m + (3/2)m + 7 = -2

4.5m = -9

m = -2

Now use m= -2 in either equation to find n.

3m-4n=-14

3(-2)-4n=-14

-6 -4n = -14

-4n = -8

n = 2

The solution of this system of equations is (-2,2).

See the attached graph, with x and y used in place of m and n.

In the given question the hand contains 4 cards of the same suit, and 1 of another suit and we have to find the probability of this.

As we know that in standard card deck have 4 suits and 13 ranks in each suit and each deck have total 52 cards. If 13 ranks separated then 39 cards are left.

So the probability that the hand contains 4 cards of the same suit and 1 of another suit is

The equivalent expression to show another way to represent the new price is b - 0.86b = c .

Step-by-step explanation:

Given that the original price of the purchase is b and the coupon gives a 14% discount, the new price of the purchase is given by:

c = b - 0.14b

To write an equivalent expression, we can multiply both sides of the equation by 100% - 14% to simplify:

c * 100% = b * 100% - 0.14b * 100%

c * 100% = b * (100% - 14%)

c * 100% = b * 86%

c = b * 86%

So, another way to represent the new price of the purchase is c = b * 86%.
