Answer:
$0.276
Step-by-step explanation:
Given data
Bill= $9.20
Tax= 3%
Tip= 19%
Let us find the amount of the tax and the tip
Tax
=3/100*9.20
=0.03*9.2
=$0.276
Amount after sales tax
= 0.276+9.20
=$9.476
Tip
=19/100*9.476
=0.19*9.476
=$1.80044
Therefore the sales tax
=$0.276
Formula 1 mi =in * 63,360
So 0.9*63,360= 57024 inches
(6,(31pi/180)+2 n pi)
(-6,(31pi/180)+2 n pi)

Answer:
The 4th option, 10g + 24 = t
Step-by-step explanation:
It costs 24 dollars per month no matter what.
$10 * the amount of GB you want
Add those two values to get the total cost per month.
In this case you want 5 GB, so substitute the g in the equation for 5. You will get:
10 * 5 +24 = t
50 + 24 = t
74 = t
So it costs 74 dollars per month to get 5 GB.
Let the two numbers be x and y.
We have x+y=45
⇒ y= 45-x.
The two numbers multiply and get 121, so we have another equation:
x*y = 121 (1)
Plug y= 45-x in (1), we have:
x* (45-x)=121
⇒ 45x - x^2 = 121 (distributive property)
⇒ x^2 - 45x = -121 (multiply -1 on both sides)
⇒ x^2- 45x + 121= 0
⇒ x= 42.128 or x= 2.872
y= 45- 42.128= 2.872
or y= 45- 2.872= 42.128.
Because it does not matter what number, x or y, is larger, the two numbers are 2.872 and 42.128.
Hope this helps~
