68,246 inches of road had been repaved before today.
Step-by-step explanation:
Given,
Length of road repaved so far = 97338 inches
Length repaved today = 29092 inches
Length repaved before today = Total length repaved - Length repaved today
Length repaved before today = 97338 - 29092
Length repaved before today = 68246 inches
68,246 inches of road had been repaved before today.

Answer:
OQ = 16
PR = 32
m<QRS = 90 degrees
Step-by-step explanation:
Since we know that PQRS is a rectangle, we can use its properties to find that:
OQ, OS, OR, and OP are equivalent, meaning that they all equal 16. Therefore, OQ = 16.
PR = OR + OP, meaning that 16 + 16 = PR, meaning that PR = 32.
And finally, m<QRS = 90 degrees because all corner angles in a rectangle are right angles.
I hope this helps!
Step-by-step explanation:
Find the unit rate of each pair of socks for the dozen. 12/9=1.3333
so then multiply 18 by 1.33 to get 23.92. So you could sell the 18 pair pack of socks for anything less than $23.92
Hope this helps ^-^
Answer:
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
