The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
4:30 hours ..............
Answer:
x=12
Step-by-step explanation:
Simplify both sides by adding like terms
5/12x=x-7
subtract x from both sides
-7/12x=-7
multiply both sides by 12/-7
x=12
I don’t understand the question 14=7
We need to find an equation in the form
.
To find
, we use the formula:
We'll use the points
and
:
The value of
(the y-intercept) is the value of
when
, which is 25.
So the equation is
(choice A).
