238% of what number is 47,600?

Given the following expression:

To determine an estimate for each expression:

A fraction can be defined as a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.

Generally, a fraction comprises two (2) main parts and these include:

In this exercise, we would simplify and estimate the given expressions as follows:

Note: An estimate simply means an approximate value.

a. [tex]\frac{1}{8} + \frac{2}{5}=\frac{5+16}{40}=\frac{21}{40}[/tex]

For the estimate:

[tex]\frac{1}{8} + \frac{2}{5}=\frac{1}{2}[/tex]

b. [tex]\frac{13}{14} -\frac{1}{10}=\frac{130-14}{140} =\frac{116}{140} =0.83[/tex]

For the estimate:

0.83 ≈ 1

c. [tex]\frac{1}{12} + \frac{1}{20}=\frac{5-3}{60} =\frac{2}{60} =0.03[/tex]

Answer: 5 feet 6 inches.

Step-by-step explanation:

12 inches = 1 foot

We can divided 66 by 12 to find how tall Joan is in feet.

66 ÷ 12 = 5.5

The term "0.5" means half, and there are 12 inches in a foot. So half of a foot would mean 6, so Joan's height would be 5 feet and 6 inches.

Joan is 66 inches tall, then the height of Joan in feet will be equal to 5.5 feet.

Multiplying or dividing by a numeric number, or more specifically, a correction factor, is a procedure comprising several steps known as conversion.

Rounding and choosing the appropriate number of significant digits may also be necessary steps in the procedure.

As per the given information in the question,

The given height of Joan = 66 inches

So, let's perform unit conversion,

1 foot  = 12 inches, so,

x foot = 66 inches

Use cross-multiplication,

12x = 66 × 1

x = 66/12

x = 5.5 feet.

Answer:

It will take 30.48 for the money in his account to double.

Step-by-step explanation:

Interest compounded anually:

With an investment of P, the amount compounded annualy after t years that you will have is given by:

[tex]A(t) = P(1+r)^{t}[/tex]

In which r is the interest rate, as a decimal.

Ren sets aside $1,000 into an online savings account with an annual interest rate of 2.3%

This means that [tex]P = 1000, r = 0.023[/tex]. So

[tex]A(t) = P(1+r)^{t}[/tex]

[tex]A(t) = 1000(1+0.023)^{t}[/tex]

[tex]A(t) = 1000(1.023)^{t}[/tex]

How long will it take for the money in his account to double?

This is t for which A(t) = 1000*2 = 2000. So

[tex]A(t) = 1000(1.023)^{t}[/tex]

[tex]2000 = 1000(1.023)^{t}[/tex]

[tex](1.023)^{t} = \frac{2000}{1000}[/tex]

[tex](1.023)^{t} = 2[/tex]

[tex]\log{(1.023)^{t}} = \log{2}[/tex]

[tex]t\log{1.023} = \log{2}[/tex]

[tex]t = \frac{\log{2}}{\log{1.023}}[/tex]

[tex]t = 30.48[/tex]

It will take 30.48 for the money in his account to double.

Answer:

Total cost of cementing the path = Rs. 17,000.

Step-by-step explanation:

Let the square garden be ABCD

Let the region inside the garden (ABCD) be WXYZ.

Given the following data;

Length of sides of ABCD = 90m

Width of path = 5m

Cost = Rs. 10 per m²

Area of ABCD = 90 * 90

Area of ABCD = 8100m²

To find the area of WXYZ;

WX = WZ = 90 - (5 + 5)

WX = WZ = 90 - 10

WX = WZ = 80m

Area of WXYZ = WX * WZ

Substituting into the equation, we have;

Area of WXYZ = 80 * 80

Area of WXYZ = 6400 m²

Area of path = Area of ABCD - Area of WXYZ

Area of path = 8100 - 6400

Area of path = 1700 m²

Total cost of cementing the path = Area of path * cost

Total cost of cementing the path = 1700 * 10

Total cost of cementing the path = Rs. 17,000

Answer:

x

Step-by-step explanation:

the variable that represents the cost per person is x

The cost per person for company A is given as: [tex]C = \dfrac{y-d}{x}[/tex] where C is cost per person and d is one time fixed delivery fee.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, let we take:

We're given that:

That means, as C is cost per person, so for x persons, it will be [tex]C \times x[/tex]

Thus, total cost = cost for x persons + delivery cost

or

[tex]y = C \times x + d\\\\[/tex]

Subtracting 'd' from both sides and then dividing both sides by 'x', we get

[tex]C = \dfrac{y-d}{x}[/tex]

Thus, the cost per person for company A is given as: [tex]C = \dfrac{y-d}{x}[/tex]where C is cost per person and d is one time fixed delivery fee.

Step-by-step explanation:

Answer:

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: It weighs 2 lbs or more

Event B: Delivered by UPS

15% of the packages that are delivered by UPS weighs 2 lbs or more.

This means that [tex]P(A \cap B) = 0.15[/tex]

More than 2 lbs:

15% of 20%(UPS)

93% of 80%(Not delivered by UPS). So

[tex]P(A) = 0.15*0.2 + 0.93*0.8 = 0.774[/tex]

a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.774} = 0.1938[/tex]

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more

Answer:

£683.10 in New York.

Step-by-step explanation:

Given the following data;

iPhone costs in London = £799

iPhone costs in Paris = €850

iPhone costs in New York = $970

£1 = €1.17 and £1 = $1.42

First of all, to find the cheapest (lowest) price for the three phones we would have to convert the prices to Pounds (£).

a. iPhone costs in London = £799

b. iPhone costs in Paris = €850

To find the price in Pounds (£);

£1 = €1.17

iPhone costs in Paris = €850/€1.17

iPhone costs in Paris = £726.50

c. iPhone costs in New York = $970

To find the price in Pounds (£);

£1 = $1.42

iPhone costs in New York = $970/$1.42

iPhone costs in New York = £683.10

Therefore, the lowest price for the iPhone is £683.10

Answer:

b

Step-by-step explanation:

Answer:

Step-by-step explanation:

There are two different techniques that I can think of for arriving at the answer. The first method utilizes combination, sometimes referred to as the “choose” operator. First, we need to know how many 6 cards hands are possible, which can be calculated using 52 choose 6, which in notation looks like  (526)   =20,358,520 . This is our denominator.

Now that we know how many total 6 cards hands there are in a normal deck, we need to find the numerator, which is how many 6-card hands can be made up of all hearts. Since there are 13 hearts in the deck, we can find that number with  (136)   =1,716 .

Completely written out in mathematical notation, the probability of drawing 6 cards that are all hearts, appears as follows:

(136)(526)=171620358520≈0.0000843≈0.00843%  

__________________________________________________

The second method that results in the same value can be found by multiplying together the chances of drawing the individual cards at each step, for example, there is a  1352  chance of the first card drawn being a heart,  1251  for the second, and so on.

This second method looks like:

1352×1251×1150×1049×948×847≈0.0000843≈0.00843  

Incidentally,  13!46!7!52!  is another way to notate this second method.

Personally, I find the first method to be cleaner and easier to work with, but some may find the second more intuitive.

Answer: 11/51

Step-by-step explanation: After you've picked the first card, if it's a face card then there are only 11 faces cards left, out of a total of 51. So the probability of the next card also being a face card is 11/51.
