Complete question :

the original blueprint of a concrete patio has a scale of 2 inches=3 feet. victoria wants to make a new blueprint of the patio with a length of 16.8 inches. original blueprints length is 14 inches and original blueprints width is 12 inches. what is the scale for the new blueprint and what is the width of the blueprint with the new scale?

Answer:

2.5 fts, 14.4 fts

Step-by-step explanation:

Given that:

Scale of original blueprint : 2inches = 3 feets

To make a new blueprint with a length of 16.8 inches, the scale for the new blueprint will be :

Original scale : 2 inches = 3 feets

Original blueprint length = 14 inches

Then,

2 inches = 3 feets

14 inches = d

Cross multiply :

2d = 42

d = 21 feets

Hence, new scale for blueprint :

16.8 inches = 21 feets

2 inches = d

16.8d = 42

d = 2. 5 feets

For the width :

14 inches = 16.8 feets

12 inches = w

14w = 201.6

w = 201.6/14

Width = 14.4feets

The time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated by a normal distribution with a mean value of 110 sec and a standard deviation of 15 sec. The fastest 10% are to be given advanced training. What task times qualify individuals for such training? (Round the answer to one decimal place.) seconds or less

Answers

Answer:

The task times is [tex]x =90.77 \ s[/tex]

Step-by-step explanation:

From the question we are told that

The mean is [tex]\mu = 110 \ sec[/tex]

The standard deviation is [tex]\sigma = 15 \ sec[/tex]

Generally the task times that qualify individuals for such training is mathematically represented as

[tex]P(X < x) = 0.10[/tex]

=> [tex]P(X < x) = P( \frac{X - \mu}{\sigma } < \frac{x - 110}{15} ) = 0.10[/tex]

Generally [tex]\frac{X - \mu}{\sigma } = Z (The \ standardized \ value \ of X )[/tex]

=> [tex]P(X < x) = P( Z < \frac{x - 110}{15} ) = 0.10[/tex]

Generally the z -score of 0.10 from the z-table is

[tex]z -score = -1.282[/tex]

[tex]\frac{x - 110}{15} = -1.282[/tex]

=> [tex]x =90.77 \ s[/tex]

A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples. Is the owner's estimate reasonable? The owner's answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with. The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with. The owner's estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.

Answers

Answer:

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.

Step-by-step explanation:

Given that:

Number of apples already available with Owner = 200

Number of bags of apples ordered with 12 apples each = 19

Number of apples ordered = 12 [tex]\times[/tex] 19 = 228

Rounding off 19 to 20:

Number of apples ordered = 12 [tex]\times[/tex] 20 = 240

Around 240 apples were ordered.

Number of bags of apples with 8 apples each, sold = 42

Number of apples sold = 42 [tex]\times[/tex] 8 = 336

Rounding off 42 to 40, number of apples sold = around 320

Therefore, 80 more apples were sold than that of apples bought.

So, according to the estimate, there will be 80 fewer apples left than they started with.

Correct answer is:

The owner's estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with

It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals. a. Identify the variables in this relationship and indicate which would be the independent variable and which would be the dependent variable.

Answers

Answer:

We want to write the cost equation for the company.

First, we know that:

It cost $20 per box.

There is a fixed cost of $2300.

Then the only variable will be the number of boxes that they make.

Where the number of boxes is the independent variable (the company can decide the number of boxes that they make) and the dependent variable will be the cost (the cost changes as the number of boxes change).

Then we can write the cost equation as:

C(x) = $20*x + $2300.

Where x is our variable, the number of boxes made by the company.

An online furniture store sells chairs for $100 each and tables for $450 each. Every day, the store can ship a maximum of 24 pieces of furniture and must sell no less than $4500 worth of chairs and tables. If 5 tables were sold, determine all possible values for the number of chairs that the store must sell in order to meet the requirements.

Answers

Answer:

Actually, there is no answer to this problem.

450x5=2250

4500-2250=2250

2250/100=22.5

Technically the "answer" to this would be 23 or more, but the problem is saying the MAXIMUM amount they can ship is 24

23+5=28

28 is larger than 24, meaning there is no answer to the problem.

There is no answer to this problem.

What is inequality?

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.

Given that, an online furniture store sells chairs for $100 each and tables for $450 each. Every day, the store can ship a maximum of 24 pieces of furniture and must sell no less than $4500 worth of chairs and tables and 5 tables are sold,

According to question,

450*5 = 2250

4500 - 2250 = 2250

Since, each chair is sold for $100, therefore,

2250/100 = 22.5

≈ 23

Since, 5 tables are already sold,

23 + 5 = 28

This is a contradiction to the given conditions, because the problem is saying the maximum amount they can ship is 24 and 28 is larger than 24.

Hence, there is no answer to the problem.

Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.17x + $15.89

Answers

Complete question :

Answer:

$92.39

Step-by-step explanation:

Given that:

Total distance = 450 miles

Amount charged for fees and taxes = $15.89

Amount charged ti redeem each mile = $0.17

In the equation:

Y = $0.17x + $15.89

X = distance Hans is flying

Y = cost of trip

Y = $0.17(450) + $15.89

Y = $76.50 + $15.89

Y = $92.39

A granola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories.The equation represents the relationship between these quantities. List the facts. * 4c + 5 = 27

Answers

Step-by-step explanation:

Given the expression that modeled the relationship between these quantities (calories from grams of carbohydrate and the rest of the ingredients) as

4c+5 = 27

From the equation, the constant value of 5 represents the calories in grams of the rest of the ingredients present in the bite.

Let us calculate the value of c from the equation

4c+5 = 27

4c + 5- 5 = 27-5

4c = 22

c = 22/4

c = 5.5

This means that the total calories of carbohydrate the granola bite contains is 4(5.5) i.e 21 calories of carbohydrate

Note that 8 cannot be the solution to the equation because for us to eliminate 5 from both sides of the equation, we need to subtract it from both sides not add. If 5 was added to both sides, the value of c would have been (32/4 i.e 8) which would have been wrong.
