Six hundred seventy-eight million nine hundred eighty-five thousand four hundred eighty-eight. (I think)
The missing length is 12km (i never promised anything xd)
Answer:
324 pi . and 36 pi
Step-by-step explanation:
Area is pi r squared, so 18x18 is 324, times pi which is 324 pi
Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi
:D
1. You have that a<span> student's pay of $18 an hour </span>is <span>$4 more than twice the amount the student earns per hour at an internship.
2. So, let's call the </span><span>hourly pay of the internship: "x". Then, you have:
</span><span>
18=2x+4
3. When you clear the variable "x", you obtain:
18-4=2x
14=2x
x=14/2
x=$7
Therefore, the answer is: T</span><span>he hourly pay of the internship is $7.</span>
Answer:
v = 15 miles / hour
Step-by-step explanation:
Given:
Distance covered by biker = s=45 miles
time taken by him = t=180 minutes
TO Find:
speed in miles per hour = v = ?
Solution:
As it is given that the distance covered is 45 miles
and time taken by him is 180 minutes
as one hour have 60 minutes
so time taken by rider = t = 180 /60
= 3 hours
this step is done because we have to find speed in miles per hour
Now
The formula for finding the distance is
distance = speed * time
or
s = v * t
we have to find v
so dividing both sides by t

it becomes

Putting the values

solving it gives
v = 15 miles / hour
which is the required speed
