I think its 2c and 9d. I am not completely sure but i hope this helps.
Answer:
He had hiked 3/12 of a mile so the answer is 8/12 of a mile
Step-by-step explanation:
You need to make 1/4 into twelves by multiplying both sides by 3 to get 3/12.
You take that and subtract it from the total distance. 11/12 - 3/12 = 8/12
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 miles
Answer:
Step-by-step explanation:
Remember that
Area of Circle = 
They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =
Divide both sides by 
.
144 = 
Now we want to solve for r (r = radius).
You need to square root each side
So now we know the radius, 
metres
Also remember that
Diameter = 
So,
Diameter = 2 times 12 = 24 metres
