Answer:
1.199 ≤ x ≤ 1.201
Step-by-step explanation:
You want ...
|y -7| ≤ 0.005
Substituting the expression for y, you have ...
|5x+1 -7| ≤ 0.005
|x -1.2| ≤ 0.001 . . . . . simplify, divide by 5
-0.0001 ≤ x -1.2 ≤ 0.001 . . . . . "unfold" the absolute value
1.199 ≤ x ≤ 1.201 . . . . . . . . . . . .add 1.2
Okay, so first, we need to find the discounted rate of the TV:
(1 - 0.2)849 = 0.8(849) = <u>$679.20</u>
Now that we know this, we solve for the price with sales tax:
1.06(679.20) = $719.952 (this can be rounded to 719.95)
The total cost of the TV is $719.95
The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion
Step-by-step explanation:
Given,
Profit received = 32%
Total profit received = $4.8 billion
Amount of profit received for mobiles = 32% of total profit
Amount received =
Amount received =
Amount received = 1.536 billion
Rounding off
Amount received = 1.54 billion
The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion

Answer:
x = 6
Step-by-step explanation:
pythagorean theorem
a^2 = c^2 - b^2
a^2 = 10^2 - 8^2
a^2 = 100 - 64
a^2 = 36
sqrt a^2 = sqrt 36
a = 6
CHECK:
6^2 + 8^2 = 10^2
36 + 64 = 100
yes.
