A realtor listed a house that was 45 yards by 10 yards. What is the total square footage of the house?

Answers

Answer 1
1 yd = 3 ft...so 45 yds = (45 * 3) = 135 ft
and 10 yds would be (10 * 3) = 30 ft

A = L * W
A = 134 * 30
A = 4050 sq ft <==
Answer 2

Answer: There is 1500 squared feet of the house.

Explanation:

Since we have given that

Dimensions of a house is given by

[tex]45\ yards\ and\ 10\ yards[/tex]

So, we need to find the square footage of the house ,

Area of house is given by

[tex]Length\times Breadth\\=45\times 10=4500\ yards^2[/tex]

Now, we'll change it into feet ,

As we know that

[tex]1\ yard=3\ feet[/tex]

So, total squared footage of the house is given by

[tex]\frac{4500}{3}=1500\ feet^2[/tex]

Hence, there is 1500 squared feet of the house.

In my block of 100 flats a painter is kept employed by painting one flat each month from January to November. The flats are painted in the same order and he takes a holiday every December. If my flat was last painted in August 2010 when will it be next painted?

Answers

January to November == 11 months.

11 flats are painted every year.

100 flats / 11 flats per year = 9 years + 1 month 

the next time it will be painted is September 2019.

Answer:

The answer is September 2019.

Step-by-step explanation:

In order to determine the date of the painting flat, we have to know how the painter works.

Every year, the painter paints 11 flats, because he paints one flat each month and he doesn't work in December.

Also, if we consider that "my flat" is currently in the first position, we have to wait until the painter paints the 100 position because the painter has to paint 99 flats more.

So, "my flat was painted in August 2010", then the painter paints 3 flats more that year (September, October, November).

Now we add more painted flats every year:

3+11+11+11+11+11+11+11+11=91

At beginning of 2019, the painter has painted 91 flats. So in 9 months later, the painter will be paint the 100 position, that is in September 2019.

Finally "my flat" will be painted in September 2019.

Step-by-step explanation:

A person or company that allows others to borrow money is called a "lender".

What is a Lender?

A lender is a person, a group (public or private), or a financial organization that makes cash accessible to a person or business with the expectation of repayment. Payment of any interest or fees will be included in the repayment.

Repayment might take place in installments (such as a monthly mortgage payment) or as a flat amount. A mortgage is one of the largest loans that individuals obtain from lenders.

The loan duration varies depending on the type of debt. While some loans are for 1-2 years, the majority are for 6-12 months.

Thus, a person or company that allows others to borrow money is called a "lender".

Which expressions are equivalent to 3(x + 3y + 2x − y)?

Answers

3(x + 3y + 2x − y) = 3(3x + 2y)
= 9x + 6y
See if any of these match an answer option.
Use distributive property, and simplify like terms.

   3(x + 3y + 2x - y)
= 3(x) + 3(3y) + 3(2x) + 3(-y)
= 3x + 9y + 6x - 3y
= 9x + 6y

Therefore, 9x + 6y is equal to 3(x + 3y + 2x - y)

Also, 9x + 6y can be factored into 3(3x + 2y).
   3(3x + 2y)
= 3(3x) + 3(2y)
= 9x + 6y

So this pair is equivalent: 3(3x + 2y) and 9x + 6y

If the temperature after 1 hour is 81 degrees celcius, what are two possible original temperatures? What is the difference between the possible original temperatures?

What is a quadratic equation?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

It is given that:

A scientist finds the temperature of a sample at the beginning of an experiment is t degrees Celcius.

After 1 hour, the temperature is t² degrees Celcius. If the temperature after 1 hour is 81 degrees Celcius.

From the question:

t² = 81

Taking square root on both sides:

t = ±√81

t = ±9

t = 9 degrees Celcius

Or

t = -9 degrees Celcius

The difference between the temperature = (9) - (-9) = 18 degrees Celcius

Thus, the two possible original temperatures are 9 and - 9 degrees Celcius and the difference between the temperature is 18 degrees Celcius.

Which equation represents an exponential function with an initial value of 500

Answers

Exponential function is characterized by an exponential increase or decrease of the value from one data point to the next by some constant. When you graph an exponential function, it would start by having a very steep slope. As time goes on, the slope decreases until it levels off. The general from of this equation is: y = A×b^x, where A is the initial data point at the start of an event, like an experiment. The term 'b' is the constant of exponential change. This is raised to the power of x, which represents the independent variable, usually time.

So, the hint for you to find is the term 500 right before the term with an exponent. For example, the function would be: y = 500(1.8)^x.

The center of an ellipse is located at (0, 0). One focus is located at (12, 0), and one directrix is at x = 14 1/12.
what is the equation that represents the ellipse?????????

Answers

The standard equation for an ellipse is
[tex] \frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} =1[/tex]
where
(h,k) = coordinates of the center
a, b = semi-major and semi-minor axes

Refer to the figure shown below.
The center of the ellipse is at (0,0). 
Therefore, h=0, k=0.

One focus is at (12, 0)
Therefore
c = 12

One directrix is at  14 1/12 = 169/12.
Because the directrix is located at x = a²/c, therefore
a²/12 = 169/12
a² = 169/144
a = 13

Because c² = a² - b², obtain
b² = a² - c²
     = 169 - 144 = 25
b = 5

Answer:
The equation for the ellipse is
[tex] \frac{x^{2}}{169} + \frac{y^{2}}{25} =1[/tex]

Final answer:

The equation that represents the ellipse with the given coordinates of the center, one focus, and one directrix is x^2/144 + y^2/(25/12) = 1.

Explanation:

The equation that represents the ellipse with the center at (0, 0), one focus at (12, 0), and one directrix at x = 14 1/12 can be found using the standard form of the equation for an ellipse:

(x - h)^2/a^2 + (y - k)^2/b^2 = 1

where (h, k) is the center of the ellipse, a is the distance from the center to the vertices, and b is the distance from the center to the co-vertices.

Since the center is at (0, 0), the equation becomes:

x^2/a^2 + y^2/b^2 = 1

The distance from the center to one focus is 12, so the value of a is 12. To find the value of b, we need to use the distance from the focus to the directrix. Since the directrix is x = 14 1/12, the distance from the focus to the directrix is |14 1/12 - 12|. Simplifying, we get |14 1/12 - 12| = 2 1/12. Therefore, the value of b is 2 1/12.

Substituting these values into the equation, we get:

x^2/144 + y^2/(25/12) = 1

Ira purchased a new dishwasher for $361.35. The dishwasher was on sale for 17.5% off. What was the original price of the dishwasher, to the nearest dollar?

Answers

Answer: $438
To solve this equation, you cross multiply. I first subtracted 17.5 from 100 in order to get the percentage value that $361.35 was of its original price. Since 100 - 17.5 = 82.5, the washing machine is 82.5% of its original price.

I cross multiplied by writing [tex] \frac{361.35}{1} * \frac{82.5}{100} [/tex], and multiplying [tex]361.35 * 100[/tex] and [tex]82.5 * 1[/tex]. The result was [tex] \frac{36135}{82.5}[/tex]. This becomes $438. There is no rounding needed to be done.

The original price of the dishwasher with a 17.5 percentage discount is $361.

We have,

To find the original price of the dishwasher, we need to figure out what the discount amount is and subtract it from the sale price.

The discount amount is 17.5% percentage of the original price, which can be expressed as:

Discount amount = 0.175 x Original price

We can rearrange this equation to solve for the original price:

Original price = Discount amount / 0.175

The discount amount is:

Discount amount = 0.175 x $361.35 = $63.25

So the original price of the dishwasher was:

Original price = $63.25 / 0.175 = $361.43

Rounding this to the nearest dollar gives an original price of $361.

Thus,

The original price of the dishwasher with a 17.5 percentage discount is $361.

it's 12π, because √36=6. 6×2= 12 :)

Final answer:

The circumference of a DVD with an area of 36π cm^2 is 12π cm.

Explanation:

The question asks for the circumference of a DVD with an area of 36π cm2. The circumference C of a circle is related to its area A by the formula C = 2√(Aπ). In this case, we need to substitute the given area of the disc into the formula to calculate the circumference.

First, we'll start by plugging in the area into the formula:

C = 2 √(36π π)
C = 2 √(36)√(π)√(π)
C = 2 × 6 × π
C = 12π

Therefore, the circumference of the disc is 12π cm.
