Answer:
20%
Step-by-step explanation:
We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.
Another way is
20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%
Answer:
x = 10
Step-by-step explanation:
Using the rules of logarithms
• log x + log y ⇔ log(xy)
• log ⇔ n log x
• log x = log y ⇒ x = y
Given
ln20 + ln5 = 2 lnx , then
ln(20 × 5) = ln
ln 100 = ln, hence
x² = 100 ( take the square root of both sides )
x = 10
Answer:
about $2269
Step-by-step explanation:
If we assume the aspect ratio of the two screens is the same, then the area is proportional to the square of the diagonal dimension.
__
The diagonal dimension of the larger HDTV is 65/32 ≈ 2.0313 times that of the smaller one. So, the price is expected to be ...
$550 × 2.0313² ≈ $2269.29
You expect the 65" HDTV to cost about $2269.
