The city says that the perimeter of the skyscraper's base must be 1,000 ft. The length of the skyscraper's base must be 50 feet longer than twice its width.

If the width of the skyscraper is 150 ft, what is the length?

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

probably .5

i can on others if necessary.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
