Answer:

The cost of house was $245000 when it was built.

Step-by-step explanation:

Given that:

Cost of the house today = $333200

Percent increase in today's price = 36%

Let,

x be the cost of house when it was built.

100 be the percentage when the house was built.

Percentage of house price today = (100+36)% = 136%

136% of x = 333200

$\frac{136}{100}*x=333200\\1.36x=333200$

Dividing both sides by 1.36

$\frac{1.36x}{1.36}=\frac{333200}{1.36}\\x=245000$

Hence,

The cost of house was $245000 when it was built.

There were 13,531 new products introduced last year. If 87% of the products introduced last year failed to reach their business

kvasek [131]

I'm assuming that since 87% failed, that would the remaining 13% was a success. If that assumption is correct, than we simply have to take:

.13 * 13531 = 1759.03 products were successful.

What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?

zimovet [89]

Answer:

The smaller addend is subtracted from the bigger addend

Step-by-step explanation:

Represent the two numbers with a and b such that a > b

So, the mathematical representation will be

$+a + (-b)$

Open the bracket

$+a -b$

This implies that the smaller addend (b) is subtracted from the bigger addend (b)

Take for instance; a = 6 and b = 4

This gives

$+6 + (-4)$

Open the bracket

$= +6 - 4$

$= 2$

Can two lines be drawn from a point not on a line that will meet the line at a right angle? at a 45° angle? explain each answer.

vichka [17]

I believe the the correct answer would be yes. Two lines can be drawn from a point that is not collinear with a certain line that will meet the line at a right angle or 90 degree angle and at an angle of 45 degrees. We can freely draw any line that would pass through a given point and would cross a given line at any direction giving us different angles and this would include a 90 and 45 degree angle.

NEED HELP ASAP. By what percent will a fraction change if its numerator is decreased by 30% and its denominator is decreased by

joja [24]

Answer:

0.7x/0.8y = x/y * 0.7/0.8 = x/y * 0.875

So the fraction is reduced by 12.5%
