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 1
Answer:

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.

A victim of phishing would most likely be contacted in which of these ways. A. In person b. By computer c. By telephone. D by fax.... I think its a but not sure

Answers

ok so basically phishing is dome online so the only logical answer would be by computer option B.
phishing is normally gettting your info
common things are like emails that say you have won
or emails from people claming to be a nigerian prince recently having come into posession of a large fortune...



phishing scams work best when the peson doing the scam is anonymus
internet is great
in person is terrible, you know who it is
internet is on computer
telephone, you can be tricked, but people are more likely to click on email than to be tricked by phone stuff
fax isn't as much


B is answer

Claire and Richard are both artists who paint canvas. Claire uses the polynomial 50x^2+250 to decide how much to charge for her paintings. Richard uses the polynomial 40x^2+350 to decide how much to charge for his paintings.In each polynomial x is the height of the painting in feet. To the nearest tenth for what height will both Claire and Richard charge the same amount for a painting?

Answers

Answer:

3.2 ft

Step-by-step explanation:

50x²+250=40 x²+350

50x²-40x²=350-250

10x²=100

x²=100/10=10

x=√10≈3.1623≈3.2 ft

Solve 3x2 + x + 10 = 0. Round solutions to the nearest hundredth.

Answers

3 x^(2) + x + 10 = 0
x = \frac{-b(+or-) \sqrt{ b^(2) - 4ac } }{2a}
x = \frac{-1(+or-) \sqrt{ 1^(2) - 4(3)(10) } }{2(3)}
: . x =  \frac{-1 +  \sqrt{-119} }{6}   OR   x = (-1 - √(-119) )/(6)

Thus the roots or the solutions to this equation are imaginary because the discriminant √(-119) is negative and a negative number is undefined when rooted.

Can you show your work for me on divided Omg 0.6 and 12.9

Answers

0.6 divided by 12.9.

0.6 is outside the house for the divide then inside the house is 12.6
then you move your decimal point over 1 place so its 06 divide by 126. 
after that 6 goes into 12 twice then your have a remainder of 09 then 6 goes into 9 once, our remainder is 3, then you put a 0 at the end of the decimal point of the 126. after that you bring down your zero and 6 goes into 30 five times.
Answer 21.5
0.04 is the answer first you have to divide then flip your second fraction then change your divide sign into multiplication then solve.
