Answer:
miles.
Step-by-step explanation:
Given that a group of hikers walked 
miles along a hiking trail. Another group of hikers walked 
that distance with the first group before turning off onto another trail. Now we need to find about how many miles did the two groups of hikers walk with each other.
To find that we just need to find half of
=
=
=
=
=
Hence final answer is miles.
Answer: 48 sq. cm.
Step-by-step explanation:
Area = l x w
= 12 x 4 = 48 sq. cm.
Check the picture below, that's a parabolic graph of a quadratic equation with a negative leading coeffficient, like this one, the one in the graph is just for initial velocity, but, the highest point is at the vertex for any of these parabolas.
and this one is not exception, so where's the vertex? what's A or the y-coordinate when the vertex is reached?, well, let's check.
so, that's the vertex, and when the width is that much, the Area reaches a maximum of that much.
It is 76.68 this was so easy lol
Answer:
The value of a = 8 and b= 2 for PQRS to be a parallelogram
Step-by-step explanation:
Given as :
Quadrilateral PQRS having side PQ , QR , RS , PS
The measure of side is
PQ = 6b , QR = 4a + 1
RS = 11b - 10 , PS = 2a + 9
The measure of angle PQR is (6x + 13) And PSR is (7x - 5)
The parallelogram become quadrilateral when its opposite sides is parallel and equal
I.e PQ = RS And QR = PS
Or 6b = (11b - 10)
Or, 10 = 11b - 6b
Or, 5b = 10
∴ b= 
= 2 or, b = 2
Again ∵ QR = PS
So, 4a + 1 = 2a + 9
Or, 4a - 2a = 9 - 1
∴ a = 8
Hence the value of a = 8 and b= 2 for PQRS to be a parallelogram Answer
