Determine the constant of proportionality in the situation below.

Every bag of peanuts costs $3.55

Answers

Answer 1

Answer:

The constant is that every bag costs $3.55

Step-by-step explanation:

Answer 2

When the bag of peanuts costs $3.55 then Constant of proportionality is 3.55

What is constant of proportionality?

The constant of proportionality is the ratio between two directly proportional quantities

Here,

Every bag of  peanuts costs $3.55

Consider the number of bags =  x

Cost of the peanut bag = y

Therefore

y is directly proportional to x

y = kx

Where k is the constant of proportionality

k = [tex]\frac{y}{x}[/tex]

if the cost of the one bag is $3.55

Then [tex]k=\frac{3.55}{1}[/tex]

k=3.55

Hence, When every bag of peanuts cost constant of proportionality is 3.55

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the total square centimeters of fabric that Sue must use to cover all faces of the ottoman?

Answers

Answer:

1926cm²

Step-by-step explanation:

Given

Dimension = 21cm by 18cn by 15cm

The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:

[tex]Surface\ Area =2(LB + LH + BH)[/tex]

Where L, B and H are the dimensions.

So,

[tex]Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)[/tex]

[tex]Surface\ Area = 2(378 + 315 + 270)[/tex]

[tex]Surface\ Area = 2(963)[/tex]

[tex]Surface\ Area = 2 * 963[/tex]

[tex]Surface\ Area = 1926cm\²[/tex]

Hence, 1926 cm² of fabrics are needed to cover all surfaces.

A rectangular building with a square front is to be constructed of materials that costs 11 dollars per ft2 for the flat roof, 14 dollars per ft2 for the sides and the back, and 15 dollars per ft2 for the glass front. We will ignore the bottom of the building. If the volume of the building is 5,600 ft3, what dimensions will minimize the cost of materials? (Round your answers to the nearest hundreth such that the dimensions increase from the smallest to the largest.)

Answers

Answer:

y = 23.14 ft

x = 15.56 ft

so the dimensions of the building will be = 15.56 ft x 15.56 ft x 23.14 ft

Step-by-step explanation:

the area of the roof = xy

cost of the roof = 11xy

the area of the sides and back = 2xy + x²

cost of the sides and back = 14(2xy + x²) = 28xy + 14x²

area of the glass front = x²

cost of the glass front = 15x²

minimize:

total cost = 11xy + 28xy + 14x² + 15x² = 39xy + 29x²

total volume = x²y = 5600 ⇒ constraint

39y + 58x = 2λxy

39x = λx2

x²y = 5600

λx = 39 which we replace into the first equation

39y + 58x = 78y

58x = 39y

(58x)²y = 58² · 5600

now we replace 58x by 39y

(39y)²y = 58² · 5600

39² · y³ = 58² · 5600

y³ = (58² · 5600) / 39² = 12,385.53583

y = ∛12,385.53583  = 23.14 ft

x² = 5600/ 23.14 = 242.04

x = 15.56 ft

triangle, then find the perimeter.

Answers

Answer:

Third side is 15cm. Perimeter is 37cm.

Step-by-step explanation:

In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.

So if the third side is 7cm

7+7=14cm which is less than 15 cm.

hence third side is 15 cm as

15+15=30cm which is greater than 7cm

15+7=22cm which is greater than 12cm

then

perimeter=15+7+15=37cm

5% of items in a large batch of items produced at a local foundry' are defective. If 50 of these items are selected at random, what is the probability that exactly 2 of the items will be defective? Round to four decimal places.

Answers

Answer:

0.2611

Step-by-step explanation:

We have x to be binomially distributed random variable which denotes the items number that are defective

We have been given n = 59 as our sample size

Probability of 5% = probability of success

1-5% = 0.95

We solve using this formula

nCxP^xq^n-x

= 50C2(0.05)²(0.95)^50-2

= 0.2611

This is the probability that exactly 2 would be defective
