Anastasy [175]

Area = 1/2 bh
96 = 1/2 x b x 8 = 4b
b = 96/4 = 24 inches

Perimeter = 3b [since the other sides are equal to the base]

P = 3 x 24 = 72 inches.

The question is this: Rationalize the denominator and simplify.

Neko [114]

9514 1404 393

Answer:

$\dfrac{20+5\sqrt{3}}{13}$

Step-by-step explanation:

Multiply numerator and denominator by the "conjugate" of the denominator.

$\dfrac{5}{4-\sqrt{3}}=\dfrac{5(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}=\dfrac{20+5\sqrt{3}}{4^2-(\sqrt{3})^2}=\boxed{\dfrac{20+5\sqrt{3}}{13}}$

This is done in different scenarios in order to take advantage of the factoring of the difference of squares. Square root terms and imaginary terms in the denominator can be eliminated in this way.

a² - b² = (a -b)(a +b)

From 1990 to 2000, the consumer price index (CPI) increased from

lutik1710 [3]

Answer:

1.09 $

Step-by-step explanation:

From 1990 to 2000 ( 10 years ) the consumer price index increased from

130.7 to 172.2 then

172,2 - 130.7 = 41.5 % was the net increase, if peaches suffered similar increase then we will look for 41.5 % of peaches price ( 1990)

0,77 ⇒ 100

x ?? ⇒ 41.5

x = 0,77* 41,5 / 100

x = 0,3196

Then price of a pound peaches in 2000 will be

0,77 + 0,32 = 1.09 $
