Answer:
No, she tipped about 18%.
Step-by-step explanation:
How much she tipped:
$25 - $21.18 = $3.82
To find the percentage, you can put this tip over the what she paid for the pizza.
[tex]\frac{3.82}{21.18} =0.18=18%[/tex]%
She only tipped about 18%

All even natural numbersStep-by-step explanation:
This is an AP with:
The first term = 1Number of terms = nCommon difference = 2Find the sum of the first n terms:
[tex]S_n= n(1+2n-1)/2=n^2[/tex]The sum is divisible by 4 if n is even number:
n = 2k ⇒ n² = 4k² ≡ 0 mod 4Plot the point (11, 7) on the coordinate plane.
Answer:
Step-by-step explanation:
When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form [tex](x,y)[/tex].
So, first, we need to plot 11 on the [tex]x[/tex]-axis (the line going left to right, horizontal) then plot 7 on the [tex]y[/tex]-axis (the vertical line)
So we first go 11 units to the right along the [tex]x[/tex]-axis then go up 7 units along the [tex]y[/tex]-axis.
Hope this helped.

Answer:
X=1
POQ= 1/3x+1/3= 1/3(1)+1/3=2/3

Answer:
x = 12.2; angles are 77.6 and 102.4 total to 180
Step-by-step explanation:
The equations they are giving you for the two angles he was correct about. When a line intersects two parallel lines, the angles on the opposite sides of the transverse line will equal 180 degrees.
So those two equations when added together must equal 180 degrees.
(5x + 16.6) + (9x - 7.4) = 180
Rearrange the equation
5x + 9x + 16.6 - 7.4 = 180
Add the x values together and subtract the regular numbers
14x + 9.2 = 180
Subtract 9.2 from both sides
14x = 170.8
Divide both sides by 14
x=12.2
The top angle in your drawing is 5x + 16.6 or
5 ( 12.2) + 16.6 = 77.6 degrees
The bottom angle in your drawing is 9x - 7.4 or
9 ( 12.2) - 7.4 = 102.4
Both angles added together is 77.6 + 102.4 = 180
Answer:
×=25 ; angle = 107 degree
Step-by-step explanation:
if a transversal line intersect two parallel lines then the sum of two consecutive exterior angles is 180 degrees.
The two consecutive exterior angles are 3x+32 and x+48.
3x+32+x+48=1803x+32+x+48=180
4x+80=1804x+80=180
4x=180-804x=180−80
4x=1004x=100
x=25x=25
The value of x is 25.
The measure of two consecutive exterior angles are
3x+32=3(25)+32=1073x+32=3(25)+32=107
x+48=25+48=73x+48=25+48=73
The measure of the larger angle is 107 degrees.

since every two meters is 3 mm in the drawing, divide 206 by 2 and get 103

Which linear inequality represents the solution set graphed?
A) y ≥ 4x + 5
B) y > 4x - 5
C) y ≥ 4x - 5
D) y > -4x - 5
Answer:
C
Step-by-step explanation:
first of all since the line is solid then we know that the answer is not D or B.
so it has to be either A or C.
now to graph it let's start with A.
you would go up 5 on the y axis and since there isn't enough space go down 4 and to the left 1. the line doesn't match with the one in the picture so A is not the answer.
now let's try with C.
you would go down 5 on the y axis and then go up 4 and to the right 1. the line matches up so C is your answer.
