Answer:
4 hours
Step-by-step explanation:
Given
Car 1:
Car 2:
--- i.e. 2 hours after car 1
Required
Determine the time car 1 will meet car 2
To do this, we calculate the distance of both cars using:
For Car 1:
For Car 2:
Open bracket
When car 2 meets up with car 1, they are at the same distance.
So:
Collect Like Terms
Solve for h
<em>Car 2 will catch car 1; 4 hours from the start</em>
Answer:

Answer:
The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with
N sides. It is equal to 360
o
N
.
Step-by-step explanation:
Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.
However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to 360
o
.
It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of
360
o
. So, if all exterior angles are equal, like in a regular polygon, each one equals to 360
o
N
.
It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is (
N

)

.
Dividing the above by N
we will obtain a value of an interior angle: (

Therefore, exterior angle of a regular polygon is 180

Answer:
11 Jars
Step-by-step explanation:
32 ounces = 2 pounds = 1 jar
So 22 divided by 2 = 11 jars
