Plan A costs a total of $95 since it says $95 for unlimited talk and text.
Plan B:
(.10 x 800) + (.05 x 1000)
The (.10 x 800) represents 10 cents per talk minute for 800 minutes.
The (.05 x 1000) represents 5 cents per text message for 1000 text messages.
Solve:
.10 x 800 = 80
.05 x 1000 = 50
80 + 50 = 130
This means Plan B will cost him $130 under these conditions.
Plan C:
20 + ((.05 x 800)+(.05 x 1000))
The 20 + represents a flat rate of $20 per month.
The (.05 x 800) represents 5 cents per call minute.
The (.05 x 1000) represents 5 cents per text.
Solve:
.05 x 800 = 40
.05 x 1000 = 50
20 + 40 + 50 = 110
This means Plan C will cost him $110 under these conditions.
Plan D:
45 + (.10(800 - 500))
The 45 + represents a flat monthly rate of $45.
The (800 - 500) represents how many minutes he has to pay for with the 500 free.
The .10 is the cost per extra minute.
Solve:
800 - 500 = 300
.10 x 300 = 30
45 + 30 = 75
This means Plan D will cost him $75 under these conditions.
In short:
Plan A- $95
Plan B- $130
Plan C- $110
Plan D- $75
The least expensive among these is Plan D, which only costs $75 per month.
Answer:
b. no, 6 + 4 < 11
Step-by-step explanation:

Answer:
b
Step-by-step explanation:
Answer:
Diagonal
Step-by-step explanation:
The measure of a television is always indicated by providing the length of the diagonal, in inches.
In fact, the actual length and height of a 32" tv are:
- Length:
L = 27.9 inches
- Height:
h = 15.7 inches
For an object with a rectangular shape, such as the TV, the diagonal of the object can be found by using Pythagorean's theorem:
where
L is the length of the rectangle
h is the height of the rectangle
Substituting the values above, we find:
Which corresponds to the diagonal of the TV.
