Answer:
or 120.8 miles per hour
Step-by-step explanation:
We first convert the distance into an improper fraction to facilitate calculation.
Average speed
= distance/time
= 
miles per hour
= 
miles per hour
= 
miles per hour
= miles per hour or 120.8 miles per hour

n7 is y
Step-by-step explanation:y
The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).
<h3>What is transformation of plane shapes?</h3>
Transformation is the change in the coordinates of the vertices that make up a plane shape.
This can be done either by translation, reflection or rotation.
Analysis:
since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.
If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )
In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).

Answer:
<h2> 23-[12+{16-(12÷3)}] = - 1 </h2>
Step-by-step explanation:
23 - [12 + {16 - (12÷3)}] =
= 23 - [12 + {16 - 4}] =
= 23 - [12 + 12] =
= 23 - 24 =
= - 1
