Answer:
Multiply 1/4 ; dividing 4
Step-by-step explanation:
Note that in each number going from left to right, it decreases by dividing 4 each time (or multiplying 1/4)
8/4 = 2 ; 2/4 = 1/2 ; (1/2)/(4) = 1/8 ; etc.
(8)(1/4) = 2 ; (2)(1/4) = 1/2 ; etc.

well you have to divide 324 by 42 which equals to 7.71 which whe you round it to the nearst tenths is equal to 7.7 so your answer is 7.7
At rate x miles/ hour drove d miles/ 4 hours;
At rate x-10 miles / hour drove d miles/5 h
d miles = x• 4 miles first rate
d miles= (x-10)•5 miles second rate
5x-50= 4x
5x-4x= 50
X= 50 miles/h to get to the beach
50-10= 40 miles/h to get home
D(√x + (1/4) sin (2x)^2)/dx = 1/(2√x) + (1/4) cos (2x)^2 * 8x = 1/(2√x) + 2x cos (2x)^2

Speed of driver = 5 miles/hours
Distance to be covered = 62.8 miles
<u />
<u>F O R M U L A ~ U S E D</u>
Speed = Distance/Time
<u>S O L U T I O N </u>
Time = Distance/Speed
= 62.8 miles / 5 miles / hour
= 12.56 hours
It will take 12.56 hours to cover 62.8 miles, if the driver is moving
with 5 miles/hours
