Hey there! :D
$43 dinner with 18% tip.
18%=.18
.18*43= 7.74
43+7.74= 50.74
The meal would cost $50.74.
I hope this helps!

Volume = πr²h
Volume = π (14)²(28) = 17.241 units³
Answer: 17.241 units³
First we need to find the equation of line .
Here the line passing through (0,-1) and (-1,1). So the y intercept is -1 here.
Now we need to find the slope , m.
So we have slope, m =-2 and y intercept , b=-1
And the slope intercept form is y=mx+b.
Substituting the values of m and b,
y=-2x -1
Here point (0,0) is a part of the shaded region.
It means point (0,0) must satisfy the inequality.
Let's plug point (0,0) in the equation
0=-1 and 0 is greater then -1. So the inequality have to be
y>-2x-1 .
Answer:
x= 0, y= -1
Step-by-step explanation:
To obtain the values of x and y from a system of equations, start by labelling the given equations.
8x +5y= -5 -----(1)
7x -3y= 3 -----(2)
Let's solve by elimination.
Here, I will be working to eliminate the y term. This is done by ensuring both equations have the same numerical value in the coefficient of y.
(1) ×3:
24x +15y= -15 -----(3)
(2) ×5:
35x -15y= 15 -----(4)
Add the two equations together since the coefficient of y has opposite signs.
(3) +(4):
24x +15y +35x -15y= -15 +15
59x= 0
Divide both sides by 59:
x= 0
Now, substitute the value of x into any equations to find the value of y.
Substitute x= 0 into (1):
8(0) +5y= -5
5y= -5
Divide both sides by 5:
y= -5 ÷5
y= -1

Answer: 2160°
Step-by-step explanation:
The sum of angles in a polygon is represented by the formula:
Sum = (n - 2) x 180° where n is the number of sides in the polygon
In this case, the complex polygon has 14 sides (n = 14)
So, (14 - 2) x 180°
= 12 x 180°
= 2160°
Thus, the sum of interior angles of a convex 14-gon is 2160°
