Infrared, is much more different compared to Bluetooth and WiFi. Infrared uses, as the name infers… the infrared spectrum of light. It is basically red light which is not visible to our human eyes. Unlike radio waves, infrared cannot pass through walls and other obstructions, so the applications are usually limited to devices that are within Line-Of-Sight or where light can travel

MissTica

Answer:

see below

Step-by-step explanation:

We can determine how much 12 ounces cost by using ratios

5 ounces       12 ounces

-------------- = -------------------

2.35                 x

Using cross products

5x = 12*2.35

5x = 28.2

Divide each side by 5

5x/5 = 28.2/5

x =5.64

If she has 10 dollars

5 ounces       y ounces

-------------- = -------------------

2.35                 10

5*10 = 2.35y

50 = 2.35y

Divide each side by 2.35

50/2.35 = 2.35y/2.35

21.27659574 =y

She can buy 21.3 ounces

How many four element subsets of \{1, 2, 3, 4, 5, 6, 7\}{1,2,3,4,5,6,7} have 11 as an element but do not have 77 as an element
levacccp [35]

If we fix 1 to be an element of a subset of size 4, then we can choose from 5 other elements (2, 3, 4, 5, and 6) to fill the other 3 spots in the subset. So there are

\dbinom53 = \dfrac{5!}{3!(5-3)!} = \boxed{10}

such subsets.
