The dimensions of the closet are 4 feet long and 12 feet wide and the perimeter is 32 feet

The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.

P=2(l+w) where l=length and w = width

Given here rectangular closet is 4 feet long and It is 3 times as wide as it is long. Thus its width would be 12 feet

Now perimeter of the closet using the formula above we get

P = 2(4+12)

   = 32 feet

Hence the perimeter is equal to 32 feet.

Step-by-step explanation:

[tex]f(2.75) = 12(2.75) + 10 [/tex]

[tex] f(2.75) = 33 + 10 = 43[/tex]

Answer:

b) (0.10p + 0.35f) + 0.0875 (0.10p+0.35P)

first is Jamir total cost + the sales tax of 0.0875 of the total cost

a. this is wrong because both is the sales tax only, theres no total cost include

c. wrong because its just also sales tax only

d. wrong because the total cost must only multiplied by the sales tax

PART B

12(0.10) + 8(0.35)

= 1.2 + 2.8

= $4   as the total cost

4(1.035)

= $4.14 as after tax bill

Therefore, the work done in this problem comes out to be 144 ft pound.

The work a force does is calculated as the product of the object's displacement and the components of the applied force of the object in the displacement direction. Pushing a block with some force and accelerating the body results in work being completed.

Here,

Given : an 8 lb mass

a height = 18ft

So, we find the work done

Using formula

=> Work done = m*g*h

=>  Work done = weight * height

=>   Work done = 8*18

=> Work done=144 ft pound

Therefore, the work done in this problem comes out to be 144 ft pound.

An example of a rational function is the first equation given, f(x)=3x²+1 over x-1.

A rational function is a type of function that can be expressed as the ratio of two polynomials. In this equation, the numerator is a polynomial of degree 2 (3x²+1), and the denominator is a polynomial of degree 1

(x-1).

The second equation given, x over 3 = 8 over 3, is not an example of a rational function. This equation is a rational expression, which is an expression that is the ratio of two polynomials, but it is not a function because it does not map a single input to a single output.

The third equation given, 1 over 3x-1 +3<0, is not an example of a rational function either. This equation is an inequality, not a function, and it does not have a ratio of two polynomials.

The probability that at least 2 babies out of a cluster of 5 babies will speak tomorrow is 47/128.

The probability that less than 2 babies will speak is

5C0 * (0.25)^0 * (0.75)^5 +  5C1 * (0.25)^1 * (0.75)^4

= (0.75)^5 +  5 * 0.25 * (0.75)^4

(0.75)^5+5*0.25*(0.75)^4 = 81/128

The formula for calculating the change in consumption is MPC x Change in Disposable Income.Thus, Tamba's change in consumption = 0.75 x $860 = $645

The marginal propensity to consume (MPC) is a measure of the proportion of an increase in disposable income that is spent on consumption. In Tamba's case, his MPC is 0.75, which means that for every $1 increase in his disposable income, he will spend 75 cents on consumption. The formula for calculating the change in consumption is MPC x Change in Disposable Income. Therefore, when Tamba's disposable income increased by $860, his consumption increased by 0.75 x $860 = $645.

Answer:

Step-by-step explanation:

The greatest common divisor of two integers a and b is a divisor common to both integers that is greater than any other common divisor. The least common multiple of two integers a and b is the smallest positive integer that is a multiple of both a and b.

To find the smallest possible value of a+b, we can start by trying to find the smallest possible values of a and b that satisfy the given conditions.

Since the greatest common divisor of a and b is 5, we know that both a and b must be divisible by 5. We can write a = 5x and b = 5y, where x and y are positive integers.

The least common multiple of a and b is 55, so we know that both a and b must be factors of 55. We can write 55 as the product of its prime factors: 55 = 5 * 11. Since a is divisible by 5, we know that a must be equal to 5 or 25. Similarly, since b is divisible by 5, we know that b must be equal to 5 or 25.

There are four possible pairs of values for a and b: (5,5), (5,25), (25,5), and (25,25). The smallest of these is (5,5), which gives us a+b = 5+5 = 10. Therefore, the smallest possible value of a+b is 10.

The line segment AB and let MN is the perpendicular bisector of AB line segment.

we prove the required result by congruence of triangles.

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure

From the figure,

Let P be any point on the perpendicular bisector MN. Join A to P and B to P.

To show AP=BP

In ΔANP and ΔBNP

PN=PN {common side in both triangles }

∠PNA=PNB=90°{ MN is ⊥ bisector of AB}

AN=NB {N is mid point}

By SAS rule of congruent ΔANP≅BNP

By CPCT (corresponding Parts of congruent triangles)

AP=BP

But P is point on MN

Therefore, every point on the perpendicular bisector of line segment AB is equidistant from the segments endpoints.

The measure of the angle ∠ACD will be 150°. Then the correct option is D.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The internal angles ∠A is 33° and ∠B is 117°.

Then the measure of the internal angle ∠C is given as,

∠A + ∠B + ∠C = 180°

33° + 117° + ∠C = 180°

∠C = 30°

The angle ∠C and angle ∠ACD are supplementary angles. Then we have

∠C + ∠ACD = 180°

30° + ∠ACD = 180°

∠ACD = 150°

The measure of the angle ∠ACD will be 150°. Then the correct option is D.

The probability that the next person will purchase exactly one costume is 0.57.

what is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

146 visitors purchased no costume.

230 visitors purchased exactly one costume.

31 visitors purchased more than one costume.

So, the total number of customers are,

146 + 230 + 31 = 407

The total visitors purchased exactly one costume are 230.

So,

P(Purchase exactly one costume) = 230 / 407 = 0.5651 ≈ 0.57
