You are a contractor who is installing new windows. You are working on a house that has 6 windows that are each 3 feet by 4 feet.If the glass for the windows costs $0.05 per square inch, approximately how much money will the glass cost for all of the window installations?

A.
$36
B.
$43
C.
$432
D.
$518

Answers

Answer:

D. $518

Step-by-step explanation:

We know that the windows are 3ft by 4ft, find the area:

A = L * W

A = 3ft * 4ft

A = 12 sq ft

12 sq ft is the area of each window in the house

Now multiply the amount of windows in the house by the 12 sqft:

12 sqft * 6

72 sq ft

The combined area of all 6 windows are 72 sqft. Now since 1 sqft is equal to 144 sq inches, simply convert the square feet into squared inches:

72 * 144

10,368 squared inches

Since each square inch costs 0.05 cents, multiply the amount of square inches by the cost of each square inch:

0.05 * 10,368

$518.4

Since D. is the closest value, that would be our answer.

Nian's graden i 4 1 5 meters long 3 under 10 meter wide what is the area of nians garden

Answers

Answer:

14 meters squared

Step-by-step explanation:

The dimensions of this rectangle are 4 1/5 meters by 10/3 meters. The area of a rectangle is: $A=lw$ , where l is the length and w is the width.

Here, l = 4 1/5 and w = 10/3. We simply multiply them together:

A = (4 1/5) * (10/3)

Let's turn 4 1/5 into an improper fraction to make things easier: 4 1/5 = 21/5. Now:

A = (21/5) * (10/3) = 210/15 = 14

The area is 14 meters squared.

Hope this helps!

Answer:

14m²

Step-by-step explanation:

Area = length × width

length = 4⅕ = 21/5

width = 10/3

Area = 21/5 × 10/3

= 14m²

Nell's mortgage is $50,150 at 10 percent for 30 years. What is her monthly payment if she must pay 8.78 points per $1,000? (Points : 1) $440.32
$439
$422.95
$385.89

Answers

I actually don't know the actual computation. I used a mortgage points calculator and inputted the data given.

The monthly payment given based on its computation was $440.10. The closest answer is 440.32.

The difference in decimal point is due to the rounding off of 8.78 points to 8.8 points in the calculator.

Help asap please!Add 4p^2+6 / 4p^2 + 2p-2 / 10p

Which statements are true about adding the rational expressions? Check all that apply

The least common denominator is 20p
.
The first fraction rewritten with the LCD is 20p^2+30 / 20p^2

The second fraction rewritten with the LCD is 4p - 4 / 20p

The sum is 24p^2-,4p+30 / 20p^2 = 12p-2p+15 / 10p^2

The sum is a rational expression.

Answers

I have to rewrite the expressions because they look very confusing.

1) The given fractions to add are:

4p² + 6        2p - 2
------------ + ------------
     4p²             10p²

2) The statements to asses are:

A) The least common denominator is 20p
.
B) The first fraction rewritten with the LCD is (20p² +30) / 20p²

C) The second fraction rewritten with the LCD is (4p - 4) / 20p

D) The sum is (24p² -4p +30 ) / 20p² = (12p-2p+15) / 10p^2

E) The sum is a rational expression.

This is the result for each statement.

A) The least common denominator is 20p

FALSE: THE LCD IS 20p², because it the least expression that contains all the prime factors of both denominators: 4p² and 10p.

See that you cannot divide 20p by 4p² but you can divide 20p² by 4p² and 10 p. So, 20p is not a common denominator.
.
B) The first fraction rewritten with the LCD is (20p² +30) / 20p²

TRUE: you get this expression from the first fraction by multiplying both numerator and denominator by 20p² / 4p² = 5:

(4p² + 6)×5 = 20p² + 30

(4p²)×5 = 20p²

=>

20p² + 30
--------------
      20p²

C) The second fraction rewritten with the LCD is (4p - 4) / 20p

FALSE: you have to multiply both numerator an denominator by 20p² / 10p = 2p

(2p - 2) × 2p = 4p² - 4p

10p × 2p = 20p²

So, the second fraction rewritten with the LCD is:

4p² - 4p
-----------
    20p²

D) The sum is (24p² - 4p +30 ) / 20p² = (12p-2p+15) / 10p²

TRUE

20p² + 30        4p² - 4p         24p² - 4p + 30
-------------- +   --------------- = ----------------------
      20p²              20p²                    20p²

And when you simplify the last fraction dividing by 2 you get:

12p² - 2p + 15
-----------------------
          10p²

E) The sum is a rational expression.

TRUE:

The sum of rational number has the closure property which means that by adding rational expression you will always ge a rational expression.
