8 because the actual answer is 792. 2 is too low and 17 is too high. so is 12

Walt has a box of 80 postage stamps. The box contains 16 stamps featuring the Bald Eagle and 40 stamps featuring the Stars and S

Sophie [7]

7/10

16 + 40 is 56, so 56 out of 80 stamps in the box feature the Bald Eagle or the Stars and Stripes.

We can simplify 56/80 further though. Let’s divide the numerator and denominator each by 8 to get 7/10.

There’s your simplified answer.

Given a quadratic equation px^2 + 8x + 2 does not have real roots. Determine the range of the values of p.

Verdich [7]

Step-by-step explanation:

For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.

For px² + 8x + 2 = 0,

We have a = p, b = 8 and c = 2.

=> (8)² - 4(p)(2) < 0

=> 64 - 8p < 0

=> 8p > 64

=> p > 8

Hence the range for p is p > 8.

When using bits to represent fractions of a number, can you create all possible fractions?.

mafiozo [28]

Every rational number has a base-2 representation, but only the ones with denominators that are powers of 2 will require a finite number of bits to fully represent it.

For example,

$\dfrac12 = 1\cdot2^{-1} = 0.1_2$

$\dfrac14 = 1\cdot2^{-2} = 0.01_2$

$\dfrac34 = \dfrac12 + \dfrac14 = 0.11_2$

$\dfrac{1023}{1024} = 1 - \dfrac1{2^{10}} = 1_2 - 0.0000000001_2 = 0.1111111111_2$

whereas a number whose denominator contains anything else like 1/3 will need an infinite number of bits to represent it exactly.

$\dfrac13 = \dfrac1{2^2} + \dfrac1{12} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{48} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{2^8} + \dfrac1{192}$

and so on, so that it has a repeating but non-terminating base-2 representation

$\dfrac13 = 0.010101\ldots_2$

You are designing an aquarium that is to have a tank holding 225,000 gallons of water. The tank will be 100 feet long and 20 fee

ziro4ka [17]

So hmmm notice the picture below

thus $\bf \textit{volume of a rectangular prism}\\\\
V=lwh\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\
----------\\
l=100\\
w=20\\
V=225,000
\end{cases}\implies 225,000=(100)(20)h$

solve for "h"
