we know that
To determine the rate per pretzel or unit rate, divide the total paid by the number of pretzel
so
<em>Jaimie's error</em>
He subtracted 42 from $126 when he should have divided $126 by 42
a) The gradient of a line perpendicular to AB is -2.
b) equation of line is y=-2x+6
<h3>What is gradient?</h3>
The gradient is the measure of the steepness of a straight line.
a)The gradient of line is
=(-2-2)/(7+1)
=-4/8
=-1/2
So, gradient of a line perpendicular to AB is -2
b)The coordinates of mid point (3, 0)
m = -2
So,
0= -6+ b
b= 6
So, equation of line is y=-2x+6

Theta = 210°
r = 4.6/2 = 2.3
Area of circle = pi * r * r
= 3.14 * 2.3 * 2.3 = 16.61
Area of sector =
(theta / 360) * area of circle
= (210/360) * 16.61
= 9.69
Answer:
-5 and 17
Step-by-step explanation:
-5+17 = 12
-5*17 = 12
