The roaming cell phone company charges $15.00 per month plus $0.20 per minute of airtime usage. If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?
Answer:
$63.00
Step-by-step explanation
Since you have sales tax, you would do a 10% sales tax for 15 dollar
10/100 = x/15
Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated
You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars
brainly please...maybe
Answer with step-by-step explanation:
x = $63.00
Since you have sales tax, you would do a 10% sales tax for 15 dollar
Equation = 10/100 = x/15
Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated
You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars.

Write the equation y=3/4x-4 in standard form
The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.
To convert the equation y = (3/4)x - 4 into standard form, we need to eliminate any fractions and rewrite it in the form Ax + By = C, where A, B, and C are integers.
The given equation is already almost in standard form, but we can proceed with the following steps:
Step 1: Multiply both sides by 4 to eliminate the fraction:
4y = 3x - 16
Step 2: Move all terms to one side of the equation to have zero on the other side:
3x - 4y = 16
The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.

Choose the best selection for the
quadrilateral with vertices at the
following points:
(0,0), (0,4), (8,4), (8,0)
A. Rectangle
B. Square
C. Rhombus
D. Trapezoid
The quadrilateral with vertices (0, 0), (0, 4), (8, 4) and (8,0) makes the rectangle.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
The given points are,
(0, 0), (0, 4), (8, 4) and (8,0).
To determine the section for the quadrilateral,
Find distance between points.
The distance between two points A(x₁, y₁) and B(x₂, y₂)
Distance
= √(x₂ - x₁)² + (y₂ - y₁)²
The distance between (0, 0) and (0, 4)
= √(0-0)² + (4-0)² = √(0)² + (4)² = √(4)² = 4
The distance between (0, 4) and (8, 4)
= √(8-0)² + (4-4)² = √(8)² + (0)² = √(8)² = 8
The distance between (8, 4) and (8, 0)
= √(8 - 8)² + (0 - (4))² = √(0)² + (4)² = √(4)² = 4
The distance between (8, 0) and (0, 0)
= √(0 - 8)² + (0- 0)² = √(-8)² + (0)² = √(8)² = 8
Since, the opposite sides are equal,
Therefore, the quadrilateral is rectangle.

A committee consisting of 4 faculty members and 5 students is to be formed. Every committee position has the same duties and voting rights. There are 8 faculty members and 13 students eligible to serve on the committee. In how many ways can the committee be formed?
Answer:
Step-by-step explanation:
This question bothers on combination. combination has to do with selection.
If 4 faculty members are chosen from total of 8 faculty members, this can be done in 8C4 number of ways.
8C4 = 8!/(8-4)!4!
8C4 = 8!/4!4!
8C4 = 8*7*6*5*4!/4!*4*3*2
8c4 = 8*7*6*5/24
8C4 = 7*5*2
8C4 =70 ways
Similarly, 5 students are to be selected from a pool of 13 students, this can be done in 13C5 number of ways.
13C5 = 13!/(13-5)!5!
13C5 = 13!/8!5!
13C5 = 13*12*11*10*9*8!/8!*5*4*3*2
13C5 = 13*12*11*10*9/120
13C5 = 1,287 ways
The total number of ways the committee can be formed is 8C4 * 13C5 = 70*1287
The total number of ways the committee can be formed is 90,090 ways

Answer 5:8
Step-by-step explanation:
Solve the system using Gaussian elimination. 6x−y+3z=−9 5x + 5y−5z = 20 3x−y+4z = −5 A (2,12,−3)open paren 2 comma 12 comma negative 3 close paren B (2,2,0)open paren 2 comma 2 comma 0 close paren C (−1,6,1)open paren negative 1 comma 6 comma 1 close paren D (−2,6,3)
Answer:
C. (-1,6,1)
Step-by-step explanation:
Given the system of equation
6x−y+3z=−9 ...... 1
5x + 5y−5z = 20 ...... 2
3x−y+4z = −5 ...... 3
Reduce the equations to two variables with 2unknown
Multiply equation 3 by 2 and add to 1.
Equation 3×2; 6x−2y+8z = −10 ...... 4
Subtract 4 from 1
-y-(-2y)+3z-8z = -9-(-10)
-y+2y-5z = -9+10
y-5z = 1 ...... 5
Also multiply eqn 2 by 3 and 3 by 5
Equation 2×3; 15x+15y-15z= 60
Equation 3×5; 15x-5y+20z = -25
Subtract
15y+5y-15z-20z = 60+25
20y-35z = 85
Divide through by 5:
4y-7z = 17 ...... 6
...................................
Solve 5 and 6
y-5z = 1 ...... 5 × 4
4y-7z = 17 ...... 6 × 1
....................................
4y-20z = 4
4y-7z = 17
Subtract
-20z+7z = 4-17
-13z = -13
z = -13/-13
z = 1
Substitute z = 1 into equation 5 to get y:
From 5: y-5z = 1
y - 5(1) = 1
y-5 = 1
y = 1+5
y = 6
Substitute y = 6 and z = 1 into equation 3 to get x;
From 3: 3x−y+4z = −5
3x-6+4(1) = -5
3x -6+4 = -5
3x-2 = -5
3x = -5+2
3x = -3
x = -3/3
x = -1
Hence x = -1, y = 6 and z = 1
The correct answer is (-1, 6, 1)

Question in the photo :) (Please help with my other questions!)
Answer:
a
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]u_{n}[/tex] = u₁ + (n - 1)d
given u₂₀ = 100 and u₂₅ = 115 , then
u₁ + 19d = 100 → (1)
u₁ + 24d = 115 → (2)
subtract (1) from (2) term by term to eliminate u₁
0 + 5d = 15
5d = 15 ( divide both sides by 5 )
d = 3
substitute d = 3 into (1) and solve for u₁
u₁ + 19(3) = 100
u₁ + 57 = 100 ( subtract 57 from both sides )
u₁ = 43
Answer:
a) u₁ = 43, d = 3
Step-by-step explanation:
Given :-
u₂₀ = 100
u₂₅ = 115
To Find :-
u₁ and d
Solving :-
u₂₀ = u₁ + 19d = 100 -(1)
u₂₅ = u₁ + 24d = 115 -(2)
(2) - (1)
5d = 15
d = 3
u₁ + 19(3) = 100
u₁ + 57 = 100
u₁ = 43
Solution :-
a) u₁ = 43, d = 3

Answer:
1.26
Step-by-step explanation:
Using the equation that the of the circumference:
C = 2Πr, you can plug in the given circumference:
7.92 = 2(3.14)r | Now you can isolate r:
7.92 = 6.28r
7.92/6.28 = r
r =1.26
The Stock Market alexzander is a stockbroker. Earns 12% commission each week. Last week, he sold $5,400 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answer:
Commission in March = $648
Commission in 2011 = $33696
Step-by-step explanation:
Given
[tex]Stocks = \$5400[/tex]
[tex]Commission = 12\%[/tex]
Required
- Determine the amount of commission
- Determine the amount of commission in 2011
This is calculated as
[tex]Amount = Commission * Stocks[/tex]
[tex]Amount = 12\% * 5400[/tex]
[tex]Amount = 0.12 * 5400[/tex]
[tex]Amount = \$648[/tex]
Since the number of weeks in a year is 52.
[tex]Yearly\ Commission = 52 * \$648[/tex]
