Amount of tip she gave,
[tex]T = 15\times 0.20\\\\T =\$3[/tex]
Amount of tax given :
[tex]Tax=15\times 0.09\\\\Tax = \$1.35[/tex]
So, total amount she paid is :
Total = Actual cost + Tip + Tax
Total = $(15 + 3 + 1.35 )
Total = $19.35 .
Therefore, total amount she paid is $19.35 .
Hence, this is the required solution.

What is 12 = 1 + a/1 -a?
Answer:
There is no solution
Step-by-step explanation:
There are no values of (a) that make the equation true.
Answer:
a = 11/13
Step-by-step explanation:
Multiply both sides by 1 - a
12(1 - a) = 1 + a
= 12 - 12a = 1 + a
Subtract 12 from both sides
= -12a = -11 + a
Subtract a from both side
-13a = -11
Divide by -13 each side
-13a/13 = -11/-13
= a = 11/13

Answer:
[tex] \rm x = - 7 \pm \sqrt{11} [/tex]
Step-by-step explanation:
Solve for x over the real numbers:
[tex] \longrightarrow [/tex] x² + 14x + 38 = 0
Subtract 38 from both sides:
[tex] \longrightarrow [/tex] x² + 14x + 38 - 38 = 0 - 38
[tex] \longrightarrow [/tex] x² + 14x = -38
Add 49 to both sides:
[tex] \longrightarrow [/tex] x² + 14x + 49 = 49 - 38
[tex] \longrightarrow [/tex] x² + 14x + 49 = 11
Write the left hand side as a square:
[tex] \longrightarrow [/tex] x² + 7x + 7x + 49 = 11
[tex] \longrightarrow [/tex] x(x + 7) + 7(x + 7) = 11
[tex] \longrightarrow [/tex] (x + 7)(x + 7) = 11
[tex] \longrightarrow [/tex] (x + 7)² = 11
Take the square root of both sides:
[tex] \longrightarrow [/tex] [tex] \sf \sqrt{{(x + 7)}^{2}} = \pm \sqrt{11} [/tex]
[tex] \longrightarrow [/tex] [tex] \sf x + 7 = \pm \sqrt{11} [/tex]
Subtract 7 from both sides:
[tex] \longrightarrow [/tex] [tex] \sf x = - 7 \pm \sqrt{11} [/tex]

Solve the linear graph
y=3x+7
points to plot:
(0, 7) (1, 10) (2, 13) (4, 19)
For the given equation of the graph, the slope is 3 and the y-intercept is 7.
An algebraic equation known as a linear equation depicts a straight line on a graph. This equation has one as the greatest power of the variable or variables at play. In other words, no exponentiation or other mathematical action is performed on the variables in a linear equation.
The general equation of the straight line is,
y = mx + c
Here, m is the slope and c is the y-intercept.
Compare the given equation with the general equation of the line,
y = mx + c
y = 3x + 7
Therefore, the slope is 3 and the y-intercept is 7.

Find the percent change:
$350 to $400
Answer:
14.29% increase
Hope this helps!
Step-by-step explanation:
The formula for this would be:
New value - Old value
Then divide the answer by the old value
Finally multiply it by 100
So it should be $400 - $350 which is $50
Then $50 ÷ $400 which is 0.125
Finally do 0.125 × 100 which is 12.5
So there has been a 12.5% increase
Hope this helps and/or makes sense!

A company rents out 11 food booths and 22 game booths at the county fair. The fee for a food booth is $125 plus $6 per day. The fee for a game booth is $80 plus $10 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
$3135 + $286d
Step-by-step explanation:
Given that:
Food booth = 11
Game booth = 22
Let number of days = d
Food booth rent = ($125 + 6d) * 11
Game booth rent = ($80 + 10d) * 22
Food booth = $1375 + $66d
Game booth = $1760 + $220d
Amount company is paid :
Food booth rent + game booth rent
($1375 + $66d) + ($1760 + $220d)
$(1375 + 1760) + $(66d + 220d)
$3135 + $286d

An equilateral triangle with side length 1 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Answer:
1/2 cm
Step-by-step explanation:
the area of the triangle is √3/4cm^2.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Here, given that,
An equilateral triangle with side length 1 cm .
we know,
area of An equilateral triangle
=√3/4×side²
so, the area of the triangle = √3/4×1
=√3/4 cm^2
hence, the area of the triangle is √3/4cm^2.
