Answer:

Step-by-step explanation:

a-b=2

\frac{27^{\frac{1}{3} b} }{9^{\frac{1}{2}a } } \\=\frac{(3^{3}) ^{\frac{1}{3} b} }{(3^{2} )^{\frac{1}{2} a} } \\=\frac{3^b}{3^a} \\=3^{b-a} \\=3^{-(-b+a)} \\=3^{-2}\\=\frac{1}{3^2} \\=\frac{1}{9}

In 2000, Florida's total population was 15,982,378 people and 183 out of every 1000 residents were 65 years and older. Determine
dmitriy555 [2]
Hello! There were 15,982,378 people living in Florida in 2000 and 183 out of 1,000 were ages 65 and over. That's 18.3% of all Florida residents, because 183/1,000 is 0.183 and 0.183 * 1,000 is 18.3. What you could do is multiply the amount of people living in Florida by the percentage, in this case, 18.3% (0.183). When you do that, you get 2,924,775.174 or 2,924,775 when rounded to the nearest whole number. Either way, you can't have part of a person. In the year 2000, there were 2,924,775 Florida residents 65 and older.

A scale drawing has a scale of 0.25 in. : 12 ft. Find the length on the drawing for an actual length of 15 ft.
lesya [120]

If 0.25 in on a drawing is 12 ft in real life, than 1 in on the drawing is 48 ft in real life.

Just divide 15 by 48

15/48=0.3125

So the length of 15 in real life to a drawing is 0.3125 inches.

The absolute value of y is further from 0.

Explanation:
The absolute value of any number is a positive. If the value of y is greater than x, then y would be further. Let’s input a number as an example. Let’s say that the absolute value of y was 9 and the absolute value of x is 4 due to the y value being larger. 4 is closer to 0 compared to 9 so the absolute value of y is further from 0.

Find the simplified product:<br> sqrt 2x^2 * sqrt18^5
makvit [3.9K]

Answer:

1944x^2.

Step-by-step explanation:

sqrt 2x^2 * sqrt18^5

= sqrt2x^2 * (sqrt(9^5*2^5))

= sqrt 2 x^2 * (sqrt9^5 * sqrt 2^5)

= sqrt2 x^2 * (243* sqrt2^5)

= 2^0.5 (243 * 2^2.5) x^2

= 2^3 * 243 x^2

= 1944x^2.

the selling price for a refrigerator is 584 if the mark up is 25% of the dealers cost, what is the dealers cost of the refrigera
tia_tia [17]
25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
