In the question it is given that the length of the blue lake trail is 11 3/8 miles. In the question it is also given that Gemma has hiked for a total time of 3 hours and each hour she has hiked 2 1/2 miles.
Now coming to solving the problem we get:
Total length of blue lake trail = 11 3/8 miles
= 91/8 miles
Distance hiked by Gemma in 1 hour = 2 1/2 miles
= 5/2 miles
Then the total distance hiked by Gemma in 3 hours = (5/2) * 3
= 15/2 miles
The distance left to cover the full trail = (91/8) - (15/2) miles
= (91 - 60)/8 miles
= 31/8 miles
= 3 7/8 miles.
So Gemma is 31/8 miles or 3 7/8 miles from the end of the trail.
Answer:
c
Step-by-step explanation:
4×2=2in
100÷2=50%
so it is c
An equation is formed of two equal expressions. The solution of the equation is w=3.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
In order to solve the equation, we need to isolate the variable in the following manner, therefore, the solution of the equation can be written as,
Divide both sides of the equation by 6.2,
Hence, the solution of the equation is w=3.

Answer:
4,500
Step-by-step explanation:
To find the number of students majoring in economics, you must turn 90% into a decimal making it .9.
Then you multiply the decimal to how many students there are (5000x.9) and that gives you 4,500.
Answer:
-2
The problem:
y=f(x)=x^2+x
find the slope of the secant line joining (-3,f(-3)) and (0,f(0))
Step-by-step explanation:
We need to first find the values that correspond to f(-3) and f(0).
f(-3) can be found by replacing the x's in f(x)=x^2+x with (-3):
f(-3)=(-3)^2+(-3)
f(-3)=9+-3
f(-3)=6
f(0) can be found by replacing the x's in f(x)=x^2+x with (0):
f(0)=(0)^2+(0)
f(0)=0+0
f(0)=0
So we want to find the slope of the line going through the points:
(-3,6) and (0,0)
Line them up-doesn't matter which point goes on top:
(-3,6)
(0,0)
---------Now subtract!
-3 , 6
The rise goes over the run so the slope is 6/-3 which simplifies to -2.
